﻿200 Heller: New Plants from 



midvein prominent : sepals lanceolate, barely 2 mm. long ; the 

 flowers solitary in the axil of nearly every leaf; petals pale red, 

 half again as long as the sepals, obovate-spatulate in shape, two- 

 cleft ; mature pods about 7 mm. long, slightly curved outward. 



The type is no. 341 I, collected July 10, 1896, on the bare, dry 

 ridge east of Lake Waha, Nez Perces county, Idaho, altitude 2500 

 feet. The plants were growing in dry stony ground. It appears 

 to be a species quite distinct from any hitherto described, although 

 it may have a relative in B. diffusa Greene, from near Deeth, 

 Nevada. That species is of different habit, however, and less 

 pubescent 



* Erigerox pulcherrimus. 



Perennial, from a stout, multicipital rootstock ; stems and foli- 

 age light green : stems about 20 cm. high, tufted at the base with 

 young leaves and the remains of the old ones, simple, slender, 

 leafy for three-fourths of their length, marked with prominent yel- 

 lowish lines, pubescent with short, appressed, white hairs, which 

 point upward : leaves all very narrow, about 1 mm. wide, the basal 

 ones linear-spatulate, about 1 . 5 cm. long, those of the stem 2- 

 4 cm. long, linear, acute, pubescent in the same manner as the 



stems : peduncles a prolongation of the stems, 2—5 cm - l° n £ : 

 heads large, 3.5 cm. in diameter, 7 mm. high ; involucral bracts in 

 about four rows, slightly spreading, linear-lanceolate, more or less 

 tinged with red, especially the tips, pubescence spreading ; rays 

 20-30, either white, pinkish, or violet blue, 1.5 cm. long, 2 mm. 

 wide, emarginate. (PL 340.) 



The type is no. 3664, collected on sandy hills ten miles north 

 of Santa Fe, New Mexico, June 5, 1897, at an elevation of 5800 

 feet. In the type specimen, the rays are violet blue, but some of 

 the other specimens have pinkish, or even white rays. It is gre- 

 garious in habit, and is one of our handsomest species. Its near- 

 est relative appears to be E. Montanensis (E. Tzveedyaniis), but it 

 is much less pubescent than that species, the pubescence being ap- 

 pressed instead of spreading, the involucral bracts are longer, more 

 acute, smoother, and the rays are longer and broader. The draw- 

 ing shows the plant one-half natural size, with a ray flower and disk 

 flower, each natural size.
