tion the peduncle bends sharply downwards, w^hile the ripe pod 

 bends sharply upwards again and thus becomes erect. It grows 

 on the edges of the sidewalks and in the crevices of the bricks all 

 over Asuncion. Also along the country roads, but outside of the 

 city it attains a much larger size, with a corolla nearly 3 cm. in 

 diameter, and the petals marked by six short purple stripes near 

 the base inside. 



Zanttioxylum JVaranjillo, Gris., Symb. Flor. Arg., 76. 



Asuncion (809). October. 



A tall shrub 2-3 m. high, in dense thickets about Asuncion. The

 each crenature, and, when fresh, quite transparent along the vena-

Asuncion (466 and 635). February-April. = Balansa 2514, and 

 Gibert 55. 



The well-known Jaborandi, a medicinal plant of great value. The 

 long racemes of dark, lurid flowers, sometimes 20 or 25 cm in length, 

 are very striking. These contrast strangely with the dark green 

 coriaceous shining foliage. The fruit is equally striking. It appears 

 to be a large pod with a thick green shell, which dehisces on one 

 side by 2 valves. Within appear 5 other pods, into which the 5 

 cells of the ovary have developed, each containing a shining black 

 seed enclosed in a bladdery membrane that hardens in drying. A 

 shrub about 1^ m. high, with smooth stem, branches, and leaves 

 and greenish bark, common in the thickets around Asuncion.

 jection about 3 mm. long ; inflorescence terminal, loose, the flowers numerous,
