At the slightly projecting apex there is a single apical cell, although it is not always quite certain which is the apical cell and which is its youngest segment. The broad base of the cotyledon is extended laterally, like the stipules of the older leaves, and there is thus inclosed a slightly depressed area, very much as in the embryo of Ophioglossum vulgatum, and within this is situated the stem apex, close to the base of the cot
