Powder.—Yellowish-brown; calcium oxalate from to in diameter, usually in aleurone grains from to Fig. 211.—A, transverse section through a mericarp of fennel: O, outer epidermisof pericarp; /, inner epidermis of pericarp; F, fibrovascular bundles; V,vittse or oil canals; S, seed-coat; EN, endosperm. B, isolated aleuronegrains from cells of endosperm of fennel showing globoids and small rosetteaggregates of calcium oxalate. C, section through the carpophore, which iscomposed chiefly of sclerenchymatous cells. in diameter (Fig. 211); fragments containing yellowish-brown vittae,from to mm. in width; sclerenchymatous fibers few,strongly lignified and with numerous oblique, simple pores; paren-chyma cells with more or less thick walls and simple pores andoccasionally reticulately thickened; tracheae few and either spiralor annular; in mounts made with solutions of potassium hydroxideor
