AUhough stomata are entirely lacking in the epicarp, theyoccur in considerable numbers in the endcxrarp. Spermoderm. i. Epidermis (Fig. 285, ep; Fig. 286). Of all thetissues, this is the most characteristic and remarkable. The cells in themature seed range in width uj) to 100 /<, and in length up to 400 n, butin aljortive seeds are much smaller. As is seen in cross section, theouter walls (Fig. 285, ep) are thin and convex, but the deep-yellow orbrown inner and radial walls are sclercnchymatously thickened (doublewalls often 20 /t), and in addition tlie radial walls and .sometimes tlieouter and inner walls have a transparent mucilaginous layer of distinctlystratified structure which nearly Tills the cell cavity. Treated with chlor-zinc iodine the mucilaginous
