N. lodbii, A. Gr., the related Californian species, of which immature fruit is now 
found in the Kew herbarium, appears to have only about eight seeds; these oblong, 
pendulous, half a line in length, and with a thickish, nearly smooth testa. The 
prolonged adnate portion of the filament has distinct, but very narrow, free edges. 
N. demissum may have almost as many seeds as WV. palmeri; but it is an annual.

Schaffner and Parry and Palmer have collected characteristic specimens of this species. 
The corolla is only two or three lines long, and (as in the figure and description) slightly 
surpassing the calyx; and the peduncles are very short. The stock or base is thick and 
woody; and even the slender branches become ligneous. Seemann’s 2083, which was 
naturally referred to this species, seems rather to belong to WV. rupicolum.
