Angelica WheeIvERI Watson. This is quite common in 

 Colorado, at middle elevations along streams. Specimens have 

 been collected at Crested Butte, Colorado Springs, Chiann Canon, 

 and at Central City. 



API.OPAPPUS SPINULOSU.S DC. and A. gracilis Gray occur 

 through Southwestern Colorado, and there seem to be inter- 

 mediate forms connecting the two. A. spinuloses 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. I^ansing, in South Park, agreeing with the 

 description of the type and different from the form var. floribimda 

 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. & Gra}^ 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 frequentl}^ 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. Parryi 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 flow^ers are light 

 pink and in an erect glomerule. 



Cnicus Drummondii Gray var. bipinnatus n. var. This is 

 either a variety of C Dmnwiondii 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
