Astragalus (Xylophacos) puniceus 



Petennial from the root, the stems decumbent, about 3 dm. 

 long, pubescent throughout with a short close silvery pubes- 

 cence, much branched: leaves pubescent like the stem, the rachis 

 about 6 cm. long and having 6-9 pairs of oblong or obovate leaf- 

 lets each 7-10 mm. long: inflorescence in a loose head becoming 

 spike-like, the corollas 2 cm. long, purple, glabrous, the banner 

 darker: calyx i cm. long, pubescent with a whitish woolly pu- 

 bescence, the teeth 3 mm. long and acuminate: legume coria- 

 ceous, sessile, 2 cm. long, curved and pointed, pubescent with a 

 whitish pubescence and slightly mottled, without a partition, but 

 the lower suture impressed. 



The stem of this plant is much longer than in other species 

 of this section of Astragalus as I know them, but the legume is 

 like that of Astragalus Missouriensis and its allies. Collected 

 at Trinidad, Las Animas county, Colorado, June 28, 1898, no. 

 1737- 

 Erigeron paucipetalus 



A small perennial growing in clumps, the stems about 

 1.5 dm. high, the upper portion glandular, the lower portion and 

 the leaves glabrous: root leaves narrowly obovate or oblanceo- 

 late and rounded or slightly pointed, tapering to a petiole, 5-8 

 mm. wide, about 3 cm. long including the petiole; lower stem 

 leaves very narrow and acuminate, 2 mm. wide and 3 cm. long, 

 becoming smaller and bract-like upward: stem branched into a 

 racemiform inflorescence, the upper heads on peduncles 3 cm. or 

 more long: involucre glandular, the bracts narrow, about 5 mm. 

 long, in two series, the outer somewhat shorter than the inner: 

 rays rather large, few, 16-20, purple. 



The relationship of this Erigeron is not plain; it is quite 

 different from other Colorado species so far as I am acquainted 

 W'ith them, but might be placed in the section with Erigeron 

 caespitosus. Collected about the sulphur springs at Sulphur 

 Springs, Grand county, Colorado, July 16, 1905, no. 3051.
