Oxytropis viscida Nutt. in T. & G. Fl. 1 341 (1850), Aragallus viscidus 

 (Nutt.) Greene, Aragallus viscidulus Rydberg. Viscid Oxytropis. Rydberg's 

 attempt to elucidate this species in the Flora of Montana has only added to 

 the confusion, while his additional species has no foundation. He refers 

 Nuttall's type to Oregon when it must have been collected either in Montana 

 or Idaho. Nuttall gives it as on the "Headwaters of the Oregon," but the 

 "Oregon" does not head in Oregon. Rydberg gives it as growing at 4000 to 8000 

 feet on hills when it is seldom found lower than 9000 feet, and then on rocky 

 ridges in subalpine places. Watson's locality was 10,000 feet elevation. In 

 his A. viscidulus Rydberg gives the habitat as dry hills and mountain sides 

 when it is always high alpine or subalpine, from timberline (11,500 feet alti- 

 tude in Utah) to 10,000 feet altitude on rocky ridges. His characterization 

 of both species is equally erroneous. He says O. viscida always has yellow 

 hairs at base of stems, when they are nearly always white as in the other. 

 He says the hairs on stem, calyx and pods are 'white and never black in O. 

 viscida while they are both, or in some cases wholly absent. One can always 

 find black hairs underneath the shaggy white ones in O. viscida, as the 

 shaggy ones get less the black ones become more evident. In O. viscidula 

 the pubescence varies likewise, but the black hairs ar more evident and the 

 shaggy ones only occasionally in evidence. In my specimens from Mt. Hag- 

 gin in Deer Lodge Valley near timber line there is no pubescence on the 

 calyx at all except the always present stipitate yellow glands which are 

 very abundant, the specimens are depauperate and the old pods broadly 

 oblong and obliquely short-apiculate, and about 1 cm. long. In my material 

 from Ryan's Lake, same valley, near timber line the calyx is shaggy with 

 white and black hairs intermixed. In my material from Lima, doubtless 

 the same locality where Rydberg got his, the calyx is loosely shaggy with 

 black hairs as well as the pods, and in specimens got close by the calyx 

 is shaggy with white hairs, with a few black ones underneath. The pods 

 vary from oblong-ovate and short-acuminate to lanceolate-acuminate, and 

 from long-beaked to apiculate in pods from the same tuft, and from a half 

 inch long to an inch long, with divergent beak. It is evident that Nuttall's 

 original was a depauperate plant with slightly developed pods. In all my 

 material, of which I have much, my field notes say the flowers are bright 

 red, in drying they turn to blue, or when not quickly dried turn white, and 

 this is probably the reason why Nuttall's specimens seem white flowered. 

 This should grow on all our high peaks. Rydberg refers Watson's material 

 from the East Humboldt Mts. Nevada, to O. viscida and mine from the 

 Wasatch to O. viscidula, while they are the same, as I have material from 

 both localities. This plant also grows at Browning on gravelly knolls.
