umna genitalis 2.5-8 mm. longa, non stipitata, apice

Stamina sex in serie unica, columnae valde adnata, anth-

Aristolochia verophytica does not seem to match closely 
any of the species included in Hoehne’s Pseudostipulosae. 
Except for its foliaceous stipules, it would seem vegeta- 
tively to resemble most closely sfristolochia rumicifolia 
Mart. & Zuce., but the flowers of the two species are 
very dissimilar, 
As the specific name implies, -fristolochia werophytica 
grows ina hot, dry and sandy region, a rather unusual 
habitat for members of this genus.
