Allionia albida Walt. Fl. Car. 84 (1788). 
There are two forms in the collection, which I refer to this species. The material 
is too scanty and poor for a satisfactory determination. One form with broadly 
lanceolate leaves was obtained at Hot Springs, altitude 1,100 m., August 3 (No. 956). 
The other form, with very narrowly lanceolate or linear leaves, grew on the plains 
between Custer and Fairburn, altitude 1,400 n., July 23 (No. 957). Both forms differ 
from A. hirsuta in being smooth up to the pedunele, and from 4, linearis in the 
leaves, which are undulate and sparingly ciliolate on the margin, and in the pedun- 
cles and involucres, which are hispid.

lucre is narrowly turbinate, and the lobes scarcely scarious-margined, and that the 
scape is more slender and the leaves are nearly glabrous above. Dry hills: Hermosa,
