epidermal layer are very characteristic, as are also the 
usually numerous vitte. Of these there are from sixteen 
to thirty in each mericarp, the largest occurring in the 
commissure. A further noteworthy peculiarity is the 
thickening of the seed coat at the commissure. 
The powder is greenish-brown, with characteristic 
odor and taste, In it may be distinguished the short, 
conical, unicellular hairs, either isolated or attached to 
fragments of the epidermal layers, fragments of the 
parenchyma, sclerenchymatous cells, and portions of 
vascular bundles from the pericarp; and small pieces of 
seed-coat and endosperm together with cluster crystals 
of calcium oxlate and aleurone grains from the cells
