Eastwoop: New SprEcirs OF OREOCARYA 241 
the banks of the Columbia River, eastern Washington, July, 
1881. 
Oreocarya elata 
Stems one to several from a woody tap-root, 3-4 dm. high, vir- 
gate, ribbed, floriferous from near the base with sessile or peduncled 
clusters which form heads of few to several flowers in the somewhat 
distant leaf-axils, later becoming spikes; summit of the stem 
branched, forming a panicle of unilateral bracteate spikes which 
are at first capitate but later lengthen, the lower flowers becoming 
distant more than their own length: pubescence of lower part of 
stem and leaves snowy white, consisting of densely appressed and 
interlaced fine hairs with some scattered appressed bristles mostly 
pustulate at base ; pubescence of the upper leaves and inflorescence 
tawny and more spreading: radical leaves densely clustered on 
the caudex, spatulate, entire or crenate, acute or obtuse, with the 
margined petioles as long as the blade, together 2-3 cm., strongly 
ribbed ; cauline leaves distant from each other 1-3 cm., lanceolate, 
together with the broad margined clasping petioles 2-4 cm. long, 
5 mm, wide: divisions of the calyx ovate with strong midvein, 
4 mm. long, 2 mm. wide at base, densely hispid, surpassing the 
tube of the corolla, enlarging in fruit, conniving over the nutlets 
but with the tips spreading: corolla white ; tube 3.5 mm. longer 
than the orbicular lobes which do not extend to the throat ; crests 
slightly emarginate, fleshy, arching over the elliptical anthers ; 
basal scales crescent-shaped, forming a ring 1 mm. from the base : 
anthers 1.5 mm. long, 1 mm. wide, on short broad concealed fila- 
ments: nutlets erect, ovate, with the lateral edges acutely mar- 
gined but not winged, obtuse, tuberculate with glossy white tuber- 
cles which are separate or confluent in irregularly transverse ridges, 
especially along the middle of the dorsal surface : gynobase subu- 
late ; scar forked at base and extending almost to the apex. 
This is nearest to O. setostssima (Gray) Greene from which it 
differs in all its parts. It was collected by the author near Grand 
Junction, Colorado, on the road to the coal mines, growing on the 
bare clay hills characteristic of the region, flowering May 15, fruit- 
ing June 28, 1892. 
Oreocarya aperta 
Caudex branched from a woody root, with leaves densely 
clustered at base and the dilated petioles imbricated : stems several, 
rather slender, 1-2 dm. high, branching from near the base with 
many spreading simple or 2-forked spikes, those of all the stems 
aggregated into a closely branched thyrse: pubescence gray, se- 
tose-hispid, the spreading white bristles pustulate at base, 2-3 mm.
