Aug. P. Decandolle Physiologie Végétale Tom. Tom 2. 1832.

p. 834 Trapa natans has 2 very marginal cotyledons, one so small as to be scarcely visible, the other large & filled with farinaceous matter. Radicle bends to side of small cot.— This large Cot entirely take place of bulb. —

[Movement in plants, p. 95: "The smaller cotyledon of one seedling was extremely thin, and not half the length of the larger one, so that it was clearly becoming rudimentary,* In all these seedlings the hypocotyl was enlarged or swollen.

In another and very different water-plant, 'Trapa natans', one of the cotyledons, filled with farinaceous matter, is much larger than the other, which is scarcely visible, as is stated by Aug. de Candolle, 'Physiologie Veg.' tom. ii. p. 834, 1832."]

one of the cotyledon which is filled with [farinaceous matter] is much larger than the other which is hardly visible; this is state by Aug— De Can.
