Wyethia cusickii n. sp. 
Whole plant slightly varnished with resin and with a suntlower-like 
odor, glabrous excej)t the ciliate margins of the canline leaves and tegnles 
and a few hairs on the upper part of the peduncles; stems stont, 60 to 100 
cm. tall, terete, rather strongly ribbed, often ])nrple-tinged; basal leaves 
firm and thick, oblong lanceolate, acute or short-acnminate, 80 to 45 cm. 
long, on margined i)etioles less than half as long as the blades, the canline 
sessile or snbsessile, gradually reduced upwards; stems hearing a solitary 
terminal head, or more frequently a smaller head from the axil of each 
of the upper leaves; larger heads 4 cm. broad; tegnles lanceolate, a few 
of the lowest ovate, acute, coarsely ciliate, 1.5 to 2.5 cm. long: rays about 
15, pale yellow, oblong, lanceolate, acute, entire at tips or 2 or 8 toothed, 
4 cm. long; bracts firm, linear, acuminate, ciliate, atomiferous-glandu- 
lar near the tip; akenes j)ubescent toward the apex. 
Found growing in swamp, Llog Valley, Blue Mountains, Union 
County, Oregon, together with IF. helianthoides and IF. amplexicauUs 
suhresinosa, by \V. C. Cnsick. Xo. 8726 (type) June 17, 1912; No. 8780 
June 17, 1912; No. 8781 June 17, 1912; No. 8,748 .May 29, 1918; No. 8770

The specimens are intermediate between the two species with which it 
grew. The leaves resemt)le closely those of IF. ample.xicaulis except for 
the pubescence which is ol the same general character as that of IF. 
helianthoides. The akenial characters and the color of the rays are tho.'^c 
of IF. helianthoides. It is not unlikely that the plants may be byhrid in 
charactei. Jlr. Cnsick writes tbat its period of bloom is also intei’inediate, 
being later than that of IF. helianthoides hut earlier than IF. amplexicauUs. 
Wyethia amplexicauUs major n. suhsp. 
Herbage hut slightly resinous; leaves thinner, often denticnl-ate, the 
basal broadly ohlongdanceolate, the cauline usually (?) petiolate; rays 
orange-yellow, 7 cm. long; akenes glabrous. 
.Mormon Basin, Baker County, Oregon, alt. 4000 ft. in open dry soil 
June 17, 1918, IV. C. Cu.sick, No. 8,861. 
IMr. Cnsick states that the more salient characters of this plant are its 
larg('r tlow'crs, larger translucent basal leaves, and stalked cauline leaves. 
On tbe whole, how'ever, tbe plant seems too closly allied to IF. amplexi¬ 
cauUs to be regarded as a di.stinct species. 
Wyethia amplexicaulis suhresinosa n. suhsp. 
Diflers from the tyjacal plant in being much le.ss resinous and in the 
foliage being j)ale green.
