This species is common about the summits of the high moun- 
tains of the Cape Region of Baja California. It is near V. tomen- 
tosa, and has been considered the same in notes concerning 
Lower California flora. Both species were in cultivation at San 
Diego, where V. tomentosa grew more luxuriantly than in the 
Cape Region. The proposed new species differs from its associ- 
ate in its virgate habit, larger, deeply serrate leaves, larger flow- 
ers, glabrous akenes and pappus. Many of the akenes are flat- 
tened, and when bearing only two awns resemble those of Encelia. 
V. tomentosa is an intricately branched shrub 5-10 ft. high, com- 
mon throughout lower elevations of the Cape Region. 
Perymenium angustifolium. Frutex cortice fusco-brunneis,

integris vel obtuso-serratis, supra scabro-strigosis, subtus pallidi- 
oribus hispidulo-hirsutis, 3-5 cm. longis, 5 mm. latis: capitulis 
2-5 corymbosis; pedicellis filiformibus 1-2.5 cm. longis adpresse
