NEW OR NOTEWORTHY SPECIES. 111 
OREOCARYA THYRSIFLORA. Biennial, erect but seldom 
simple, the erown of the root usually producing 3 or more 
equal stout stems a foot high, these leafy toward the base 
and rather amply thyrsoid-panicled from below the middle: 
leaves all oblanceolate, obtuse, strigose-hispid : branches of 
the inflorescence forked, and with a flower in the fork: 
calyx hispid and hirsutulons, the segments narrow, not 
elongated: corolla-tube not exserted, very short: nutlets 
only 14 lines long, ovate, obtuse, acutely-margined, dorsally 
rather sharply but interruptedly rugose. i 
Very common on stony hills in southern Wyoming about 
Cheyenne, Laramie, &c., thence to middle Colorado. 
OREOCARYA INTERRUPTA. Perennial, tufted, 14 to 3 feet 
high, canescently tomentulose throughout, the stems and 
stem-leaves, also the calyx, hispidly hirsute: radical leaves 
oblanceolate, acute, tapering to a broad hispid-ciliate petiole: 
stem leafy below, above the middle interruptedly floriferous, 
the inflorescence uninterrupted and thyrsiform only at sum- 
mit: calyx elongated, the segments 4 or 5 lines long: corolla 
smaller than in allied species: nutlets elongated-ovoid, ob- 
tuse, dorsally marked by a distinct but little raised median 
ridge and many low tuberculations seldom approximating 
the transversely rugose. 
This I have not seen in any herbarium; but it was col- 
lected by myself in the mountains of eastern Nevada, in 
July last. It abounds in open woods some miles east of 
Wells. 
OREOCARYA FULVOCANESCENS (Gray), Greene, Pitt. i. 58. 
The type is Fendler’s 632, from the mountains of New Mex- 
ico. It has a densely silky-tomentose herbage, only the in- 
florescence displaying a yellow hispid hairiness; the leaves 
are linear-spatulate and acute. | With this type the plant of 
Nevada and eastern California, called Eritrichium fulvoca- 
nescens, Gray, is not to be confounded. That may be named 
and characterized as follows:
