SMITH: STUDIES IN THE GENUS LuPINUS—X 93 
have not seen these, Mr. Johnston’s critical notes have made it 
possible for me to recognize the species and name the Arizonan 
collection here recorded. 
CHIHUAHUA: Cumbre, on the summit of the mountains above 
Batopilas, 8850 feet, 1885, E. Palmer 318 (G); summits of the 
Sierra Madre, Oct., 1887, C. G. Pringle 1483 (G) 
ARIZONA: Cochise County: Chiricahua Mountains, May, 
1894, W. W. Price (DS, CPS). 
This appears to be a species with fair characters, although 
closely allied to L. manus, which it resembles not a little. The 
fistulous character of the stems and branches seems to be one of 
its strongest peculiarities.

4. Lupinus ASCHENBORNII S. Schauer, Linnaea 20: 739. 1847. 
In my seventh paper I listed this species as a member of the 
Micranthi. This was done because I have, for some four years, 
been interpreting a certain Chihuahuan plant as Schauer’s 
species. His description is unusual in its comprehensiveness, 
and applies quite well to the specimens concerned; but no hint 
is given as to the ciliation of the keel. Recently, however, I 
have been favored with flowers for dissection from specimens 
from Southern Mexico and Costa Rica, all labelled L. Aschen- 
bornii. Since three possible species seem to be included in this 
small assortment of material, I now feel it necessary to withhold 
my treatment of both Schauer’s species and the Chihuahuan 
plant until after I have had opportunity to study Aschenborn’s
