8 Colorado Plants. [ZOE 
ANGELICA WHEELERI Watson. ‘This is quite common in 
Colorado, at middle elevations along streams. Specimens have 
been collected at Crested Butte, Coloraco Springs, Chiann Cafion, 
and at Central City.

APLOPAPPUS SPINULOSUS DC. and A. Gracinis Gray occur 
through Southwestern Colorado, and there seem to be inter- 
mediate forms connecting the two. A. spinulosus is exceedingly 
variable, and the forms might easily be mistaken for new species 
in different localities. 
ACTINELLA RicHARDSONII Nutt. This was collected by 
Miss Alida P. Lansing, in South Park, agreeing with the 
description of the type and different from the form var. floribunda 
common in Colorado. It has a few large heads, and the stems 
are shorter and stouter, while the variety has a cyme of many 
small flowers, and leaves in almost filiform divisions. 
ACTINELLA GRANDIFLORA Torr. & Gray. This has the 
involucre from densely white woolly to almost glabrous, heads 
from one to three inches in diameter, leaves occasionally simple 
and linear, more frequently few to several lobed. Stems leafy 
or nearly naked and scape-like. 
CNICUS ERIOCEPHALUS Gray. A few plants collected on 
Mt. Hesperus, of the La Plata Range, in Southwestern Colorado, 
seem to approach C. Parry so closely that it is uncertain under 
which species to place* the plants. The foliage is nearly 
glabrous, the involucral bracts have no lacerate fimbriate tips, 
the woolly hairs on the bracts are not dense, the flowers are light 
pink and in an erect glomerule. 
Cnicus DRumMMonNDII Gray var. BIPINNATUS n. var. This is 
either a variety of C. Drummondii or a new species. At present 
it seems better to consider it in the former light, and give the 
characters which distinguish it from the type of the species. 
Stems several from the root, two feet or more high, sparingly 
tomentose along the stem and the margins of the leaves; leaves 
divided into many linear lanceolate divisions that are themselves 
parted into similar lobes of variable length, the lower lobes often 
as long as the leaflet; the lobes are linear and about one-fourth inch
