227. Antennaria concolor Piper, l. c., p. 604. 
Cespitose, the ligneous rootstocks and stolons slender; stems slender, 
erect, 20 to 30 em high, sparsely tomentose; basal leaves thin, spatulate, 
2,5 to 3,5 cm long, whitish, abruptly acuminate, concave on the lateral 
margins, the greener upper side becoming nearly glabrous the second 
season; cauline 7 to 9, linear or linear-lanceolate; inflorescence of 4 to 
7 short-peduncled heads in a corymb; involucre 8 to 9 mm high; bracts 
in about 3 ranks, mostly acute, greenish below, fuscous in the middle, 
the tips paler or white. 
Type specimens collected by the writer in open places in fir woods 
near the suburb of Portland, Oreg., known as Mount Scott, June 6, 1904, 
no. 6189. A few colonies only were found, all pistillate. — 
The species is perhaps nearest to A. Howellii Greene, which was ab- 
undant in the same locality, but that has larger and thicker leaves, 
nearly always smooth and green above with the lateral margins nearly 
straight and with the heads usually sessile.
