Journal of the Straits Branch of the Royal Asiatic Society. ines but along two linesfrom top to base on opposite sides, generally rather more than 180°removed from each other on the side of the partial septum, sothat this portion of the husk is rather larger than the other: thenthe hypocotyl elongates and curves to direct the radicle into thesoil (fig. 5) ; if the radicle succeeds in anchoring, a tendency inthe hypocotyl to straighten itself which now succeeds to the other,pulls the cotyledons from the loosely imprisoning fruit-walls, andthe stage which is seen in figure 6 passes over to that seen in Jour. Straits Branch NOTES ON D1PTEBO0AKPS. 163 figure 7. If there happens a most unlikely occurrence in nature,—that the cotyledons cannot be pulled out, and the root does not hold,the latter by the straightening of the hypocotyl is raised up intothe air, and held. The cotyledons at this time move so as to become nearlyhorizontal and stand thus unless as not seldom happens their lobesengage, when they remain face to face as figure 6 Figs. 5 and 6, Shorea leprosula the root being placed in the earth. A glance at figure -I shows than any impression of the placentaswill be on the lower surface of the inner cotyledon only, but thatimpressions of the radicle may be on the lobes of both. In figure5 the impression of the placentas is seen crossing the lobes of theinner cotyledon: and in figure 8 the impression of the radicle maybe observed. Fig. 7. Shorea leprosula, reduced toJ, at the expanding of the first leaves,
