Ratibida tagetes cinerea var. now 

 From the typical form this plant differs in being cinereous 

 almost throughout: the stems and lower surface of the leaves are 

 covered with a usually dense pubescence composed of rather 

 coarse, appressed, and straight, or sometimes somewhat matted, 

 pointed hairs; the upper surface of the leaves is green, and with 

 much less abundant pubescence: the divisions of the leaves seem 

 to be rather wider than in the species. 



Type collected at Harrison's ranch near Pecos, New Mex- 

 ico, August 21, 1908, Standley 5156, growing on a dry hillside 

 at an altitude of about 6700 feet. The plant was associated with 

 the species but was readily distinguishable, the collector think- 

 ing at first that it was the typical form of the plant affected by 

 some fungus. 



4410. Coreopsis eanceolata R. Distributed under this 

 name rather reluctantly, because it seems to differ in several par- 

 ticulars from the eastern form of the species. The material in 

 our herbarium is insufficient for satisfactory comparison of the 

 plant, which should, from its geographical location, be distinct. 

 It was collected on a mountain side near the Pecos river, grow- 

 ing under pine trees. The specimens have considerable pubes- 

 cence on the lower part of the steins, and the upper leaves are 

 all 3-parted and distinctly petioled. The leaves seem to be rela- 

 tively wider than those of .eastern specimens of C. lanceolata 

 that we have seen. The plant reproduces by stolons, a method 

 of propagation which explains the fact that the stems occurred 

 singly. The plant was not at all abundant in the one locality 

 where it was collected, but attracted notice at once on account 

 of its large and handsome heads. 



4809. Achillea alpicola R-ydb. Truchas Peak. Read- 

 ily distinguished from A. latmlosa^ which occurred at timber 

 line only a few hundred feet below, by its dwarfed habit and the 

 darker edges of the involucral bracts. 



. 4255. Arnica cordifolia Hook. Shaded hillsides along 

 Winsor creek. 



5069. TRAGOPOGON PORRIFOLIUS k. Rather eoinnion in 



cultivated fields about Pecos; also along Santa Fecreek at Santa 

 Pe.
