19. Boerhaavia organensis Standley, sp. nov. 
Annual ?, low, 20 to 25 em. high, branched from the base; stems minutely 
puberulent below, glutinous above; blades 2 cm. long or less, elliptical to 
lanceolate, thick, glabrous, paler below, rather obtuse at both ends, the petioles 
short and thick; inflorescence diffusely paniculate, the branches rather stouter 
than in B. gracillima; flowers solitary on filiform pedicels which vary in length 
from 1 em. to shorter than the flower; no very good flowers on the type but 
those present about 1 mm. long, each subtended by a short, lanceolate bract; 
fruit glabrous, 3 mm. long and about 2 mm. wide, the ribs rather acute, much 
wider above than below, almost truncate above, the ribs rugulose. 
This is nearest B. gracillima, from which it differs in the smaller size of 
the plant, less diffuse panicles, much smaller flowers, and the glabrous fruit 
of different form. Type in the herbarium of the New Mexico Agricultural 
College, collected in Filmore Canyon, Organ Mountains, New Mexico, October 
23, 1904, Wooton. B. gracillima is common in the same locality.
