VANCOUVERIA HEXANDRA (Hook.) Morr. & Dec. 
Woods at the head of Coos river, 4872 in part, September

Vancouveria brevicula Greene, sp. nov. 
Plant low, and for the genus rather delicate: scapes exceed- 
ing the foliage, the lesser 3 inches high, the larger twice as 
high, few flowered (4 or 5 flowers, rarely 6): leaves large for the 
plant, the spread of them over the ground far surpassing the 
height of the plant, but the many leaflets small, one-half to 
three-fourths inch long, often nearly as broad, 3 to 5 lobed, but 
the lobes very shallow, leaf texture not coriaceous: flowers large, 
more than one-half inch long, white, autumnal: fruit not seen. 
Type, no 832 in part, collected at the head of Coos river, 
September 3, 1911, in the National Herbarium. 
According to Professor Greene, my number consists of two 
species, the real Vancouverta hexandra aud V. brevicula. Also 
collected by Dr. Hayden, as no. 92. It may be that the autuim. 
nal flowering condition of this species is merely a rejuvenes- 
cence, due to the warm autumnal rains, such as ocenrs in this 
region in the case of Trifolinm, Mimulus, Viola, Mttella, and 
many other herbaceous vernal plants. The large flowers and 
small herbaceous leaflets, however, are very different from those 
of the ordinary species of Vancouverta.
