The Secret World of Crops: Tales of higher than 100 excellent flowers, timber, and seeds by Ben Hoare, 2022. Dorling Kindersley.
I don’t often analysis plant-based books meant for a youthful viewers. However, this publish appraises one such title, The Secret World of Crops by Ben Hoare.
What you get
The Secret World of Crops, which is revealed by DK Children, is promoted as a “nature e-book for teenagers ages 7+”. In approx. 180 pages, it packs in a surprising amount of plant biology. Because of the author’s web site for this e-book doesn’t embody a desk of contents, I hope this overview will in all probability be of price to potential readers/purchasers of this tome.
Setting the scene
Introduction – whose ‘take-home message‘, “With out crops, life as everyone knows it is not going to exist” (p. 5), doesn’t get any further essential than that. There adjust to 4 2-page sections.
World of Crops – a summary outline of the precept extant plant groups (masking “spherical 400,000 species of plant” (p. 6))– which includes inexperienced algae – and plant evolution (and likewise mentions fungi and lichens – because of they look like crops, nonetheless aren’t).
Leaves – begins with: “Most crops might make their very personal meals [a clear nod in the direction of those plants that don’t – e.g. corpse flower, which is covered by Hoare], and their leaves are the factories [use of which word gives an indication of the audience the book is geared towards] the place it happens” (p. 8). The determine of that course of – photosynthesis – is obtainable elsewhere on p.8, as is a summary overview of its chemistry.
Flowers – although purists would possibly baulk at labelling what are clearly the sepal equivalents of the lily flower as ‘petals’, the final knowledge – which includes components of a flower, feminine and male flowers, and pollination – seems excellent, and is summarised in a strategy that’s acceptable for the meant viewers.
Seeds – covers basic seed development and germination, and supplies a ‘shout-out’ for seed banks (Rebecca Gosling; Bonnie Grant).
The precept textual content material
is packaged primarily as a bunch of 2-page devices, each of which determine a specific plant – with its English frequent determine, and its scientific determine precisely italicised – and develop particular factors of the plant organ beneath which heading they’re included (along with completely different knowledge such as a result of the plant’s utilization by people or its ecological significance). In affect, these items are mini-essays. An indication of their contents is obtainable beneath.
Leaves
Significantly curiously, this half begins with an entry for phytoplankton. Although they have no leaves [as Hoare acknowledges], it does current the prospect to say that “There are so many phytoplankton on Earth, all ending up photosynthesis, that they launch further oxygen than all of the world’s land crops put collectively” (p. 17). A named desmid, a single-celled inexperienced alga (Wim van Egmond), is the featured phytoplankter. This half moreover incorporates the highly-modified leaves of the Venus flytrap (illustrating a way by which crops obtain extra mineral food regimen), the fragile plant (and promotes herbivore-defence as the reason for the leaf-dropping behaviour of this plant),* and the great bougainvillea (which affords the prospect to show “a selected type of leaf often known as a bract” (p. 45)).
Stems and trunks
Consists of: horsetails (and reference to their historic place inside the formation of coal deposits); the tendrils of sweet pea (which always curl to the correct, so it’s a ‘right-handed plant’…); fire-resistant massive sequoia (whose ripe cones open with fire releasing their seeds into nutrient-rich ash); and the water-storing trunk of the baobab.
Roots and bulbs
Choices: the air plant (making the aim that not all crops get their water by way of roots, and supplies us a superb check out water-absorbing scales on leaves of an epiphyte [which term is used and explained]); the strangler fig (a plant that may kill completely different crops); cassava (and likewise stating that potato tubers, although rising underground, are “massively swollen stems” (p. 86)); and nitrogen-fixing nodules on clover.
Flowers
Begins with seagrass (and a reminder that some flowering crops reside not solely fully submerged, however moreover beneath the ocean on this event versus freshwater lakes or rivers) [this entry is also used to mention the manatee and the seagrass ecosystem to make the important point that plants are not separate entities divorced from an association with other living things in the environment, but it is not clear to me why kelp forest is also included in this entry]; lotus (with acceptable level out of its beetle-trapping flowers, and the plant’s cultural and spiritual significance); and coralroot orchid (making the aim that not all crops use photosynthesis, some are ‘vampires’ – as Hoare calls them – because of “they suck out water, nutritional vitamins and sugar” (p. 115) from completely different crops…).
Fruits and cones
Showcases the night-flowering dragon fruit (making the aim that not all crops flower all through the day, and as a consequence of this truth need nocturnal pollinators comparable to bats); banana (whose ‘youngster fruit’ start out straight nonetheless develop to be curved as they develop away from the underside in route of the sunshine; and which will also be an opportunity to comment upon fragility of meals present since there is a fundamental downside with fungus affecting Cavendish bananas), and lodgepole pine [although most of the plants mentioned in the book are flowering plants, gymnosperms, such as this pine, do get a mention – and there is a 2-page spread devoted to conifer cones in this section].
Seeds and nuts
Wheat begins this half, appropriately adequate because of it’s acknowledged to be “the first cereal grown by folks higher than 10,000 years up to now” (p. 163), on the dawn of agriculture. Maize (“a world mega-crop” (p. 166)),** espresso, and coco de mer (with its leaves that catch rain, which is channelled proper right down to the roots alongside the deep folds inside the trunk) are moreover included. As is dandelion and its ‘clock’. Nonetheless, do bear in mind that the feathery buildings launched from the clock are actually fruits (George Briggs; Cynthia Kelly et al.), and by no means seeds as acknowledged inside the e-book.
The plant biology part of the e-book ends with Crops of the World – a 2-page unfold that comes with a map of the world displaying the geographical homes of some of the planet’s “most spectacular and bizarre crops” (p. 184) (a minimal of some of which – e.g. heather, Australian Christmas tree, and welwitschia – is not going to be talked about elsewhere inside the e-book), and a reminder that many worldwide areas – nonetheless solely specified for Canada – have a nationwide plant.
There then follows a Glossary (two 3-columned pages, from ‘alga’ to ‘wildfire’), and an Index (of approx. 4 3-columned pages, from ‘acidity’ to ‘yew tree’, by way of: bark; caffeine; dinosaurs; ecosystem, seagrass; farming, historic; germination; hemiparasites; insect pollination; Jurassic Interval; Khasi people; left-handed crops; mimicry; nectar; oil palm; pollinators, insect; quinine; rainforests; selective breeding; toxins; ultraviolet delicate; vanilla; and wholegrain bread). There aren’t any entries for ‘X’, so, presumably, there’s no level out of ‘xylem’ inside the e-book [nor is phloem listed under ‘P’], and none for ‘Z’. For crops, frequent names are listed, nonetheless not scientific names (although the latter are used in-text).
The Secret World of Crops concludes with Acknowledgements [in which we learn that Dr Jonathan Mitchley – aka ‘Dr M’ – Associate Professor in Field Botany at the University of Reading, UK, was a consultant for the book].
Practically every net web page is illustrated – typically with every photographs and beauitiful artwork work by illustrator Kaley McKean. There is no such thing as a such factor as a indication of the place the information provided inside the e-book has come from, nor any suggestions of extra learning.
Further nuanced analysis of the e-book
Phrases and images
The author’s enthusiasm for the topic materials shines via the textual content material inside the e-book, which is collaborating and well-written (and Hoare’s liberal use of exclamation marks may be seen as every an indication of his pleasure with crops, and an try to enchantment to the age-range of the meant viewers whose private literary journeys are constantly affected by these punctuation marks (Joseph Brean; Adam Lusher; Stephen Poole & Neil Frizzell; Florence Hazrat)). Furthermore, the e-book is fantastically – and abundantly – illustrated with many photographs and drawings of crops and plant components. Textual content material is fairly minimal in relation to the number of illustrations, which may be seen as a superb demonstration of the earlier adage that “a picture is value a thousand phrases”. On the themes of images, a number of of them current very small objects, comparable to seeds, a 2-page unfold of a false-coloured scanning electron micrograph of stomata, and a nitrogen-fixing module on a clover root. Because of these buildings may be unfamiliar to the readers it’ll have been helpful if some sense of scale had been indicated (and an announcement included that the SEM image had been false-coloured). The highly-magnified wheat grain on p. 162 doesn’t desire a scale since its measurement is acknowledged inside the legend.
It’s all inside the ‘packaging’
There’s more than likely no one, supreme approach to present plant natural knowledge. The tactic used proper right here – primarily based spherical named plant components – may be practically pretty much as good as any. Accordingly, beneath a plant half – comparable to leaves, or flowers – we have got fully completely different factors of plant biology related to that organ. To do that, each of the 2-page mini essays depends spherical a named plant – whose English frequent determine and scientific determine are given. Nonetheless, the e-book doesn’t keep all through the considerably slim confines of plant anatomy that the organ-based methodology might counsel. Instead, each entry takes the prospect to place the named plant and plant half proper right into a wider natural context. As an illustration, it would focus on plant physiology, pollination biology, fire ecology, plant sickness, and varied sources of nutritional vitamins. Quite a few plant biology is crammed into this e-book.
And, Hoare doesn’t stop there. He moreover inserts completely different knowledge which can solely give his readers a higher appreciation of crops in a further human context. As an illustration, inside the entry for cassava he makes the aim that not all plant meals is safe, it would need processing to remove toxic compounds – hydrogen cyanide (Joey Kwok; Njoku Damian Ndubuisi & Ano Chukwuka Ugochukwu Chidiebere (2018) Int J Genom Data Min 2018: 118; doi: https://doi.org/10.29011/2577-0616.000118) on this case – from the starch-rich roots. Furthermore, in telling us that “as a lot as 500 million people in Africa depend on cassava” (p. 86) [here is support for that statement] as a staple meals provide, he introduces his readers to staple foodstuffs previous these cereals that they may be further accustomed to in/from Europe, Asia and North America. The utility of crops – and crops components and merchandise – and the relevance of crops to people is a vital theme that runs all by way of the e-book, and reinforces the message the e-book begins with “with out crops, life as everyone knows it is not going to exist” (p. 5).
However, attempting to constrain commentary to the named plant half is an methodology that is not with out its oddities. As an illustration, lots is claimed about water-absorption by leaf scales of the air plant in an essay ostensibly about ‘roots’. And the entry on lotus (beneath ‘flowers’) incorporates – and illustrates – a big level out regarding the barely-wettable leaves of this plant. Furthermore, the 2-page spreads that time out a variety of crops which may be included beneath each plant half have some quirks. For instance, beneath ‘Roots and bulbs’, the Flavourings merchandise incorporates a variety of which can be nothing to do with roots or bulbs, e.g. chillies, sugarcane, vanilla pods, cinnamon, coriander leaves, and saffron (although ginger and garlic do slot in with the plant organ coated on this half). And the unfold on Plant merchandise, which includes henna leaves, papyrus stalks, willow bark, sandalwood heartwood, aloe vera leaves, and kelp (which surprising inclusion is compounded by the reality that brown algae seem like actively excluded from the organisms considered to be crops on p.16!), has nothing to do with ‘flowers’ throughout which half it appears. The one exact flower included in that selection is dried flowerheads of lavender (and, at a push, one can also accept cotton ‘fibres’ as flower-related). However, considerably than make an unlimited fuss about this, let’s recognise that it underlines the difficulties involved in sticking to the topic. And, on the plus side, inside the assortment of Useful fruits (beneath ‘Fruits and cones’), all are fruits, and all of the Tasty seeds (beneath ‘Seeds and nuts’) appear to be seeds.
What variety of crops..?
The e-book’s sub-title – Tales of higher than 100 excellent flowers, timber, and seeds – is intriguing for two causes. First, that trio would appear to exclude all of the tales regarding leaves, stems, roots, and so forth. Why not substitute ‘flowers, timber, and seeds’ with ‘crops’? Second, the place does the considered “higher than 100” crops come from? Having examined the e-book pretty fully, I counted 55 crops – 56 once you embody the desmid – that had been significantly dealt with inside the 2-page mini-essays. That is pretty a strategy wanting 100. If one added-in crops which may be talked about very briefly inside the assorted ‘spreads’ in each half – after which solely by their frequent names – it would attain the required entire. Nonetheless, any tales knowledgeable about these are very poor in contrast with the species dealt with inside the devoted 2-page devices. Readers anticipating 100 crops to be coated within the similar diploma of aspect are destined to be disillusioned.
Feeding the readers’ thirst for further plant knowledge
For the e-book’s meant youthful readership [don’t forget, it is published by DK Children, and is promoted as a “nature book for children ages 7+”], it is attainable that little or no of its contents will in all probability be acknowledged to them. It is as a consequence of this truth totally acceptable that this tome be entitled ‘the important thing world of crops’. And a minimal of some of the secrets and techniques and strategies which may be shared – comparable to parasitic crops, delicate crops, strangler fig, squirting cucumber, vampire crops, insect-mimicking orchids, flowers that look and odor like rotting meat, and an unlimited seed that seems like a unadorned bottom – usually tend to seize their consideration and encourage them to want to know further. In that strategy their curiosity about crops will in all probability be elevated, and, should they go on to hunt out out further about crops, their botanical literacy (Britt Board) can solely be enhanced. From these small beginnings [yes, do think ’acorns and mighty oak trees’], we’d however create the plant-knowledgeable people with the requisite ‘botanical functionality’ (Andrea Kramer & Kayri Havens, Pure Areas J 35(1): 83-89, 2015; https://doi.org/10.3375/043.035.0112/) which may be wished to ensure right stewardship of the planet. With that goal in ideas it’s a selected shame that there is no indication of: first, the sources of the statements of fact made inside the e-book, and second, suggestions of extra learning for these plant information-hungry youthful minds to go on to.
As a ‘children’s e-book’ – although a factual one – one doesn’t basically rely on to see indications of sources, each in-text or on the end of the e-book. Nonetheless, that’s solely because of one is used to not seeing this achieved [it’s not done in a lot of fact-based books for adults, but that’s another story!] in books geared towards children. Nonetheless, there’s no goal why there can’t be some acknowledgement of the place the author has purchased his knowledge from – even a ‘bibliography’ may be helpful for that. And, since certainly one of many targets of the e-book is to encourage its readers to hunt out out further about crops (Creator’s Introduction on p. 5), providing particulars of various plant-relevant books to take their pursuits extra may be an superior service to the youthful readers. As author Hoare acknowledges, the plant kingdom is big. By itself, this e-book will not do it full justice; suggestions of various books to try subsequent will solely be of revenue. And one such e-book that would presumably be promoted proper right here is Dorling Kindersley’s very private The Science of Crops. One different I’d advocate is How Crops Work by advertising advisor editor Stephen Blackmore.
DK versus the BBC
In 2022 I reviewed The Inexperienced Planet by Simon Barnes – the e-book of the BBC TV assortment of the similar determine. I moreover appraised The Inexperienced Planet by Lisa Stewart-Sharpe & Kim Smith, which moreover presents “tales from the enduring BBC TV assortment” (primarily based on the sticker on the e-book’s entrance cowl). The latter title was primarily a mannequin of the earlier that was tailored for a lots youthful viewers. In numerous respects Dorling Kindersley’s The science of crops [appraised earlier in 2023] and Ben Hoare’s The Secret World of Crops [also published by Dorling Kindersley] may be seen in lots the similar strategy. However, and although every Stewart-Sharpe & Smith’s The Inexperienced Planet and Hoare’s The important thing world of crops are meant for a youthful readership, with its fairly a number of photographs, glossary, index, and a further grownup textual content material, Hoare’s e-book should additionally enchantment to older readers as correctly.
Summary
Ben Hoare’s charming e-book – The Secret World of Crops – covers a substantial amount of plant biology and ecology and amount of plants-and-people supplies in a strategy that’s acceptable for its meant readership. However, although geared towards a youthful viewers, it doesn’t dumb-down the science, and makes use of technical phrases*** the place very important. If dad and mother, or completely different grown-up family members, study this e-book with the youngsters, every adults and the F1 period may be taught tons from this stunning publication.

** Having included wheat and maize on this half, it seems a little bit of bizarre that there’s no separate entry for rice. As a cereal which may be a staple for approx. 3.5 billion people, one-half of the world’s inhabitants (Deepa; Naomi Fukagawa & Lewis Ziska, J Nutr Sci Vitaminol (Tokyo) 65(Complement): S2-S3, 2019; doi: 10.3177/jnsv.65.S2), which has some noteworthy choices of its biology [e.g. flooding-tolerance (Demilade Fayemiwo] and custom (Michael Bryan), good relevance to genetic modification of crops [think ‘golden rice’], and lots of people-relevance [e.g. it was the other major crop – along with wheat – that was significantly improved during the Green Revolution (Grace Brewer; Amanda Briney)], it’ll seem like an acceptable candidate for inclusion inside the e-book. Instead, it’s solely level out appears to be as certainly one of many ‘Tasty seeds’ inside the 2-page unfold of that title.
*** Readers of a certain age – these considerably older than 7+ – may be disillusioned (nonetheless not totally shocked?) to be taught that the determine ‘ethylene’ (Francis Carey) is now formally no further; it’s often known as ethene (Simon Cotton) – and solely ethene – inside the e-book. After I used to be being launched to plant physiology the 5 classical plant hormones (Hans Kende & Jan Zeevaart, The Plant Cell 9(7): 1197–1210, 1997; https://doi.org/10.1105/tpc.9.7.1197) had been often known as auxin, abscisic acid, cytokinins, gibberellins, and ethylene. Having to now identify the fifth one ethene will in all probability be exhausting to do, and accept…
