Paraguay Jaborandi, yielded by P. pinnatifolins, and (3) Maran- 

 ham Jaborandi, obtained from P. micro phyllus. The name, jabor-

 besides those of the genus Pilocarpus (p. 305). 



Fig. 257. Pilocarpus pinnatif alius: A, transverse section of lamina showing upper 

 epidermis (E), oil gland (Se), palisade cells (P), some of which contain rosette aggregates 

 of calcium oxalate, loose parenchyma (m), some of the cells of which contain calcium 

 oxalate (o), and lower epidermis with a stoma (Sp). B, surface view of epidermis showing 

 basal portion of a non-glandular hair (h). The remains of hairs are often found, the hairs 

 themselves having been rubbed off. C, view of the under surface of the lamina showing 

 stomata (sp). D, diagram showing the arrangements of the tissues in one of the secondary 

 veins: P, palisade cells; m, loose parenchyma; Sc, sclerenchyma; s, sieve; g, tracheae. 

 E, transverse section of the primary or middle vein showing palisade cells (P), elongated 

 parenchyma (p), oil glands (Se), sieve (s), tracheae (g), which surrounds parenchyma (m), 

 thus distinguishing it from the secondary vein. F, surface view of upper epidermis of 

 lamina. After Meyer.
