i;ii»ci(ni poeosonsis sp. nov. 



Perennial from a slender rootstock: steins erect, mostly 

 about 25 cm. high, rather stout, striate, soft pubescent through- 

 out or becoming glabrate below, not glandular: radical leaves 

 spatulate, obtuse, tapering to a short, winged petiole, bright green, 

 glabrous, except the usually ciliate margins, the blades about 

 30 mm. long and 12 mm. wide; stem leaves lanceolate or ob- 

 long, obtuse and mucronate or acute above, sessile by clasping 

 bases, glabrous, except the long-ciliate margins; the upper stem 

 leaves not much reduced, but the stems not appearing very leafy: 

 heads 1 to 7 on short peduncles, the disk about 13 mm. wide and 

 7 mm. high, the purple rays very narrow and very numerous, 

 extending about 1 cm. beyond the disk: bracts in two series of 

 equal length, linear, with acute or acuminate tips, appressed or 

 the tips slightly spreading, glandular puberulent and usually 

 with rather abundant villous hairs. 



The plant strongly suggesis E. macranthus, but its smaller 

 size, more pubescent stems, usually less acute leaves, and more 

 or less villous bracts distinguish it. Type collected in a wet 

 meadow along the Pecos river near Winsor's ranch, July 16, 

 1908, Standley 4358; altitude about 8200 feet. 



A very handsome species, growing everywhere along the 

 streams in this region. The same plant was also collected along 

 Ponchuelo creek near the forks, July 4, 1908, Standley 4181. 

 The latter collection was from a drier place, made before the 

 rains had begun, circumstances which help to explain the minor 

 differences between the plants of the two numbers. 



No. 4830, collected on Truchas Peak above timber line, 

 August 8, 1908, at an altitude of over 12000 feet, seems to be a 

 low, subalpine form of this. It is only about 1 dm. high, and 

 there is only a single head on each stem; the rays, too, are of a 

 deeper purple, otherwise there does not seem to be much differ- 

 ence between this and the type. 



5041. Helianthus aridtjs Rydb. Near Pecos, growing 

 with //. lenlicularis, but readily distinguished beeause of its nar- 

 rower, shining leaves. A few plants were seen at Winsor's.
