184 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
linear-oblanceolate, obtuse, 20 cm. long or less, the uppermost shorter and 
narrower, cinereous but not densely so; heads small, about 7 mm. wide; 
peduncles very slender, terminating the branches, mostly naked; involucral 
bracts in about 2 series, green, thin, nearly linear, slightly glandular, sparingly 
hirsute, abruptly acute; rays 25 to 30, pale purple, 3 mm. long; achenes slender, 
conspicuously compressed, nearly glabrous; pappus deciduous, uniseriate, of 
few weak, white bristles. 
Type in the U. 8. National Herbarium, no. 687233, collected on dry hills at 
the north end of the Carrizo Mountains, July 30, 1911, by Paul C. Standley 
(no. 7433).

The plant was first collected by Miss Alice Eastwood along the San Juan 
River in southeastern Utah, July 12, 1895. Probably it is what is reported as 
E. bellidiastrum in Rydberg’s Flora of Colorado, said to come from McElmo 
Canyon. It is nearly related to that species, but is a very low, diffusely 
branched plant, very unlike H. bellidiastrum in habit. The rays are brighter 
colored and the leaves shorter and narrower. 
Erigeron gilensis Wooton & Standley, sp. nov. 
Biennial or possibly only annual, 35 cm. high, branched from the base; stems 
several, slender, erect, with numerous leaves, copiously strigose, the pubescence 
near the base mostly spreading; leaves oblanceolate to narrowly oblong or 
linear-lanceolate, the lower obtuse, the upper acute, sessile or attenuate to the 
base, sparingly strigose on both surfaces; heads few, on slender, erect peduncles, 
the disk S or 9 mm. wide; bracts linear, acute or attenuate, villous, slightly 
viscid; rays numerous, about 100, lavender, linear, 5 mm. long. 
Type in the U. S. National Herbarium, no. 690243, collected on the North 
Fork of the Rio Gila, August 4, 1900, by E. O. Wooton. 
This is related to Erigeron divergens, but the pubescence is mostly appressed 
instead of spreading, and the plant is greener, more slender, lower, and less 
branched. 
Erigeron rudis Wooton & Standley, sp. nov. 
Perennial from a stout, creeping, branched rootstock, 4 or 5 stems or more in 
each clump; stems erect, a meter high or fess, stout, striate, hirsute throughout, 
usually simple below; radical leaves oblanceolate to spatulate, acute or obtuse, 
entire, 12 cm. long and 14 mm. wide or smaller, 3-nerved, bright green, scabrate 
or glabrate, long-petiolate; cauline leaves lanceolate or oblong-lanceolate, 6 cm. 
long and 2 cm. wide or smaller, very numerous, the plants appearing densely 
leafy, the leaves little reduced above, acute, sessile by broad, somewhat clasping 
bases, scabrous on both surfaces, ciliate; peduncles stout, short, villous, glan- 
dular, ascending; heads 8 to 8, the disk about 15 mm. wide and 7 mm. high; 
rays numerous, very narrow, light purple, about 12 mm. long; bracts linear, 
appressed, glandular-puberulent, in about 2 series; achenes strigose, the pappus 
in 2 series. 
Type in the U. 8. National Herbarium, no. 330495, collected in the White 
Mountains, Lincoln County, August 1, 1897, by E. O. Wooton (no. 270).
