comes to the habitat of E. subalpinum. Then again, far to 
the northwestward of Colorado, in northern Idaho and north- 
western Montana, the region of E. wmbellatum being again 
left behind, the hills of the cooler and moister country are 
the abode of a rank and large growth of the same E. subal- 
pinum. Or, proceeding from Colorado directly westward, 
the higher, more snowy elevations of the mountains of Utah 
and Nevada yield only E. subalpinum, the dry foothills the 
other; while still further westward, to the south of Idaho, 
namely along the dry western borders of the Great Basin, 
toward California and Oregon, E. umbellatum is abundant, 
- .and even variable in several respects; but there is nothing 
_ approaching Z.subalpinwm in any of those regions. On the 
— whole, E. umbellatum has a range over about three times the 
- territory that Æ. subalpinum has; and yet they seem to meet 
and grow together only on the bleak subalpine plains of 
Wyoming, and that without any intermixing even there. 
HEDYSARUM OCCIDENTALE. Stem erect, finely striate, glab- 
_ rousand shining, 1 or 2 feet high: leaves subsessile, the lowest 
= with very long sheathing stipules; leaflets 17 to 21, elliptic 
or ovoid-elliptic, 6 to 8 lines long, thin, villous-pubescent 
along the midvein beneath and the margin,ending in a very 
prominent villous cusp: flowers red: loment of but one or 
two very large obovoid joints, these 5 or 6 lines long, trans- 
versely veined (scarcely reticulated) and sparsely hispidulous 
with curved white hairs. 
Olympic Mountains, Washington, 1890, C. V. Piper. Plant 
like H. boreale when in flower, though with broader leaflets 
-and widely different fruit. : 
POTENTILLA REFLEXA. P. glandulosa, var. reflexa, Greene, - 
Fl. Fr., 65. Rather minutely villous-hirsute throughout, 
and somewhat glandular, the cymose branching very loose 
and open: small round-obovoid petals very deep yellow, 
‘barely equalling the calyx-segments and with them some-
