True time capsules of life, seeds are significant items of hope and promise. They are the most complex organs plants ever produce, and come in an enormously diverse range of shapes, sizes, and colours; from the impressive coco de mer nut to the microscopic seeds of an orchid, to the extraordinary cobalt blue of the traveller's palm pit. Seeds are often overshadowed by the adult plant's size and show. Here, 600 seeds are spotlit, each given equal attention, each shown as glorious photographs, life size and in detail, alongside an engraving of the parent plant. Every profile includes a population distribution map, a table of essential information, and a commentary revealing notable characteristics, related species, and a diagnosis of the specimen's importance in terms of taxonomy, rarity, dispersal method, and scientific significance. Arranged taxonomically, this essential reference reveals the variety and importance of seeds to an extent never seen before.
