112 PITTONIA. 
OREOCARYA HUMILIS. Eritrichium glomeratum, var. humile, 
Gray, in part. Perennial, cespitose, 6 to 10 inches high, 
strigosely hirsute and hispid, with some tomentose pubes- 
cence on the lowest leaves, these obovate, obtuse, tapering 
spatulately to a long slender petiole: flowering stems rather 
slender, equably floriferous from near the base to the sum- 
mit, the flowers solitary or few in the axils of leaves and 
bracts, the whole forming a narrow spiciform thyrsus: co- 
rolla-tube scarcely exceeding the long calyx, the hairs of the 
latter not yellow: nutlets ovate, abruptly narrowed at sum- 
mit, with an indistinct dorsal ridge, rather densely tuber- 
culate but not rugose. 
Frequent in the mountains of Nevada and adjacent eastern 
California; the Californian plant, as collected by Mr. Sonne, 
having nutlets nearly twice as large as in the more typical 
form of eastern Nevada, yet otherwise quite the same. 
OREOCARYA NUBIGENA. Apparently perennial and cespi- 
tose like the last, with similar foliage and the same harsh 
bristly pubescence: stems as low, slender, but floriferous 
only near the summit, and the glomerate inflorescence inter- 
rupted: corolla-tube little or not at all exserted: nutlets 
elongated-ovate, not in the least rugose or granulate but 
smooth or slightly wrinkled. 
On Cloud’s Rest, Mariposa Co., California, 10 July, 1889, 
Messrs. Chesnut & Drew. This has heretofore been lis 
as O. leucophza, on account of its having smooth nutlets; 
though in habit, pubescence and form of the corolla, it is as 
distinct as need be; and, as belonging to the eastern slope 
of the Sierra Nevada, it is quite outside of the territory of 
M. leucophxa, and under very different climatic influences. 
The species is much nearer O. humilis notwithstanding that 
its nutlets are so different from those of that group. 
OREOCARYA CONFERTIFLORA. Perennial, tufted, the nu- 
merous stems from an almost ligneous branching caudex, à 
foot high or more, leafy up to the strictly terminal dense
