1902] Greene — Some New Northwestern Composite. 279 



Collected in the Chilliwack Valley, B.C., 29 July, by Mr. Jas. 

 M. Macoun, No. 26,847; also earlier at Revelstoke, No. 11,334, 

 and again from the Warm Springs, Kootenay Lake, both in 

 British Columbia, in the year 1890. No. 34,05-^ from Salmon 

 Arm, J. R. Anderson, 1899, is also the same. The species is related 

 to G. decurrens, yet very distinct in hnbit and inflorescence, the 

 dense white-woolly pubescence of the upper part of stems and 

 branches of the panicle being very peculiar. 



Gnaphalium proximum. Annual, erect, rather slender, a foot 

 high, rather amply leafy, even up to the subsessile leafy-bracted 

 clusters of heads : leaves thin, equally hoary on both faces, about 

 lyi inches long, from ovate-lanceolate to oblong-lanceolate, 

 broadest at the sessile and subcordate-clasping base, somewhat 

 cuspidately acute : small plants simple and with but a terminal 

 cyme ; larger ones with many short but strict branches, each with 

 its cyme : bracts of the rather smallish involucres greenish-white, 

 the outer broadly triangular lanceolate and acute, the inner very 

 obtuse : pappus rather scanty, dull-white. 



In moist ground in the vicinity of the Mammoth Hot Springs, 

 Yellowstone Park, Messrs. A. and E. Nelson, 1899, distributed 

 under No. 6,036 for G. Sprengeln, from which the species differs 

 widely in habit, form of foliage, etc. 



Arnica l^vigata. Near A. LatifoLia and as large, the 

 herbage of a deeper green and of much more thin and delicate 

 texture : radical leaves from round-ovate and cordate to lance- 

 ovate and subcordate, 2 to 3 inches long, on slender petioles as 

 long, the 2 or 3 cauline pairs broad and sessile, glabrous on both 

 faces and coarsely, incisely, often doubly serrate-toothed, the 

 larger 3 inches long and more than 2 in breadth : peduncles 

 about 3, slender, puberulent under their narrowly turbinate in- 

 volucres, the bracts of these uniserial, lanceolate, acuminate, 

 scarcely pubescent except as to the villous-ciliolate margins ; rays 

 light-yellow, long and narrow ; disk-corollas narrow-funnelform, 

 the very short and hirtellous tube passing gradually into the 

 limb, which much exceeds it in length : pappus white ; achenes 

 glabrous.
