NOVITATES OCCIDENTALES. 19 
Thermopsis velutina. 7. Californica, var. velutina, 
Greene, Eryth. i.81. Stouter than 7. Californica and much 
smaller, in maturity densely villous-tomentose throughout, 
the pubescence of only the younger or growing parts more 
appressed and somewhat silvery-silky: stipules often larger 
than the leaflets, 14 inches long, obliquely ovate and obtusish 
or ovate-lanceolate: leaflets from narrowly to broadly and 
somewhat rhomboidly ovate, mostly acutish: racemes short 
and short-peduncled: ovaries densely white-tomentose. 
The plant was first made known to me, and imperfectly, 
from Mt. Hamilton, which must be its northern limit; and it 
now proves to be frequent five hundred miles to the south- 
ward, in the mountainous parts of San Diego Co., Calif. 
It is certainly quite distinct from T. Californica. 
Ranunculus Populago. Stem solitary from a fascicle of 
fibrous roots, erect, leafy, the whole plant flaccid and glab- 
rous, about 6 to 10 inches high: leaves thin-membranaceous, 
from round-reniform to cordate-ovate, obtuse, entire or 
obscurely crenate, on long petioles; the cauline smaller, 
ovate and ovate-lanceolate, sessile: peduncles many, slender, 
surpassing the cauline leaves to which they are axillary: 
flowers yellow, 4 inch broad; petals 5 or 6, obovate-oblong: 
heads of rather numerous thick short-pointed achenes small, 
globose or depressed -globose. 
A somewhat rare plant of the mountains of eastern Oregon 
and adjacent Idaho, distributed by Mr. Cusick and others 
under various names, but a very well defined new species, 
resembling a diminutive Caltha palustris; but the plant is 
not aquatic. 
Ranunculus eximius. Near R. adoneus, but radical 
leaves very few, often 1 only, on a short stout petiole 1—2 
inches long, the blade of cuneate-obovate or almost flabelli- 
form outline, deeply about 7-lobed at the broad summit, 
otherwise entire; upper cauline leaves sessile, broadly 
cuneiform, 1 inch long, cleft to the middle into about 5 lan- 
ceolate or broadly linear lobes: periphery of the expanded
