the capsule: capsule oval: seeds 12, irregularly ellipsoidal, beauti- 
fully alveolate, seal brown when mature. 
Possibly this may best be referred to the section Euroca Gray, but even in 
this section there seems to be no species nearer to it than P. linearis (Pursh) 
Holz. That, however, is a very different plant in its mode of branching, in its 
different and glandless pubescence, and probably in all of its floral parts as it 
evidently is in its calyx. It is interesting that this little annual possessed 
(according to the field notes) a “‘strong vile odor, something fierce,’ reminding 
one of those perennials like Goopp1no’s P. foetida that proclaim their identity 
while they are still a long way off. 
The type is no. 2232, Gold Creek, Nevada, July 27, 1912; moist sunny flat. 
Oreocarya cilio-hirsuta, n. sp.—Biennial or, apparently, some- 
times perennial, from a slender taproot more or less branched at 
summit; the branches of the caudex or crown short and clothed 
with the inordinately crowded linear leaf-bases: stems several- 
many, very slender, somewhat angled, greenish but thinly hirsute 
and with an admixture of long white stiff ciliate-appearing hairs, 
15-30 cm. long and floriferous in the axils for half their length: 
crown leaves very numerous, 2~4 cm. long, linear, the upper part 
more or less spatulate and not more than half as long as the slender 
petiolar portion; cauline shorter, mostly broadly linear; all with 
pubescence similar to that of the stems: the rather small axillary 
thyrsoid clusters 10-15, crowded above, more open below and 
usually surpassed by the foliar bracts: inflorescence moderately 
hirsute-hispid: calyx lobes linear-lanceolate, 6-8 mm. long in fruit: 
corolla tube barely as long as the calyx, its lobes suborbicular, half 
as long as the tube: nutlets ovate as to the body but narrowed and 
subacute at apex, bordered by a filiform wing-margin, sparsely but 
sharply muriculate on the back, even more minutely on the ventral 
side, not at all rugulose; scar linear, nearly as long as the nutlet, 
slightly enlarged at the base but not forked. 
The type is no. 1799, from Minidoka, Idaho, June 23, 1912, where it was 
growing in the loose sagebrush soil. MACBRIDE’s no. 93 from New Plymouth, 
May 21, 1910, and his no. 875, from Sand Hollow, June 2, ror1, were dis- 
tributed as O. affinis and O. affinis perennis respectively. Neither of these 
accord very closely with the species to which they were referred, and although 
not identical with the species here proposed, they will probably have to be 
considered a part of it rather than of O. affinis.
