This coat consists for the most part of obliteratedcells forming a cellulose layer from 2-4 [i thick, but on the ventral sidethe cells are often well defined. Endosperm (£). This consists of a single layer of aleurone cells. Embryo. Two large cotyledons, each in cross-section semielHptical,make up the bulk of the embryo. The thin-walled cells contain pro-tein and fat but no starch. Style and Stigma (Figs. 260 and 261). The strawberr}^ style is dis-tinguished from the styles of other edible rosaceous fruits by its constrictedbase and the large size and transparency of the epiderm cells. It isabout mm. in diameter in the middle part, but tapers somewhat toward 348 FRUIT. the stigma, and very markedly toward the base, where it is less mm. in diameter. T
