Inner Structure.—See Fig. 87. Powder.—Dark reddish-brown; numerous irregular yellowish-brown or brownish-black fragments of secondary perisperm, showing 204 SCIENTIFIC AND APPLIED PHARMACOGNOSY. Fig. 87.—Myristica. A, transverse section through the kernel showing theouter layer of perisperm (hp) with its inward ramifying projections (v),which extend into the endosperm (d); in the latter are irregular cavities (s)in which occurs a lighter and more recently developed tissue correspondingto the endosperm. B, a surface view of the perisperm with brownish thin-walled cells and containing an amorphous reddish-brown substance in whichrod-shaped crystals of either calcium carbonate or a salt of tartaric acid mayseparate. C, transverse section showing perisperm composed of thin-walled lignified cells having a reddish-brown content; cells of endosperm (E)containing either starch grains (am), aleurone grains (al), tannic acid, or areddish-brown amorphous substance (/); secondary perisperm (F) compose
