SMITH: STUDIES IN THE GENUS LUPINUS 397

I have dissected flowers and made drawings from fourteen of 
the numerous collections examined and here listed. As shown in

variation. The lower lip is entire in only one of these fourteen 
cases, i.e. Heller’s Reno collection. Five cases show a three- 
toothed lower lip, four cases the two-toothed condition, and two 
collections show both two-toothed and three-toothed individual 
calyces. 
Rydberg’s L. scaposus is evidently a pathological phase of L. 
brevicaulis. I have examined the type collection (T, G, RM) and 
cannot find justification for recognizing this form even as a variety. 
Three other collections, from as many states, include specimens of 
this variation. These are: ‘‘Jones 5273, Kanab, Ut.’’ (RM 
14246); ‘““‘Lemmon, Camp Lowell, Ari.’”” (G); and ‘“‘Watson 223, 
Coyote Mts., Nev.’’ (T). We should not overlook Watson’s 
own record (1871, p. 53) which reads: 
A form of this was collected with some of the peduncles much elongated and 
bearing above the leaves loose racemes of reduced florets, apparently perfect in all 
their parts, but usually sterile (223). 
I see only the one species in this series of specimens. If the 
extremes of western Nevada were alone before me, I could readily 
accept Heller’s segregate as a variety of Watson’s species; but
