broad as the anthers, inserted in the throat, the free portion about 
as long as the anther; the style nearly as long as the corolla. 
This is probably a part of the 47. Zanceo/ata (Pursh) DC. of Gray in Proc. 
Am. Acad. 10:53, and of the Syn. Fl. 2: 201, though it is very distinct from 
what Pursh and De Candolle understood by that species. The original seems 
to have been that glaucous, glabrous (at most slightly scabrous) plant which 
we know from the eastern slopes and foothills of the Rocky mountains, and 
which extends eastward toward the Missouri in the hill regions. That has 
rather thick fleshy leaves and has fewer stems. I have for years been familiar 
with it in southern and eastern Wyoming. During the season of 1899 Mon- 
tana and northwestern Wyoming, where the species now proposed is common, 
came under my observation. It did not occur to me that anyone could pos 
sibly have called it J/. lanceolata, so different are they in the field. M. 
amoena may be recognized by its cespitose habit, its hirsute (almost cinereous 
and never glaucous) leaves and stems, and the more crowded inflorescence, 
which in young plants reminds one of J/. oblongifolia, It has the habit and 
leafiness of J/. foliosa, and is more clearly distinct from J. Janceolata than 
M. Fendleri is from that species. 
Collected at Monida, Mont., June 1 5, no. 5413; Glen creek, Yellowstone 
park, June 29, 1899, no. 5556; at both of which places it was abundant.

by a branched caudex bearing a few surculiferous branches which 
terminate in a fascicle of leaves: stems single from the crowns
