Notes o?i the Flora of Custer Co. , Colorado. — III. n 



in Delta and Mesa counties. Bombus rufocinctus, cress, visits 

 its flowers in Custer Co. 



Achillea millefolium, L — Exceedingly abundant in Cus- 

 ter County, and known also from the following counties: 

 Pueblo, Routt, Fremont, Lake, Eagle, Garfield, Mesa, Summit, 

 Delta, Gunnison, El Paso and Saguache. I have found Can- 

 tharis compressicornis on its flower heads in Custer Co., also 

 Trichodes ornatus. 



Senecio feudleri, Gray. — Frequent in open ground. 



Troximon aurantiacum, Hook. — Not rare at about 8,400 

 feet, but I fonnd it more commonly in Delta Co. 



Campanula rotundifolia, L. — abundant, and also found in 

 Mesa, Delta and Summit counties. There is a variety which 

 has white flowers, and it is a most singular fact, first noticed by 

 Mrs. M. E. Cusack, that these turn blue in drying for the her- 

 barium. Campanula uniflora, L. , and C. planiflora, Eng. , also 

 occur in Custer Co. 



Arctostaphylos uva-ursi, Spreng. — Covering large tracts 

 of ground in the woods, begins to flower in the latter part of 

 April. A var. alba, with the flowers white, and smaller than the 

 type, occurs rarely. The ordinary form was also found in Pueblo 

 and Summit counties, and Miss M. Sidford reports it from Colo- 

 rado Springs, El Paso Co. 



Pyrola secunda, L. — Not unfrequent in the mountains. 

 Dodecatheon meadia var. alpinum, Gray. — In the mount- 

 ains, to 11,000 ft., abundant. 



Androsace septentrionalis, L., and A. occidentalis, 

 Pursh. — Abundant about the edge of the timber and in clearings 

 at 8,200 to 8,500 ft. 



Primula parryi, Gray. — Very frequent high up on the 

 range. The smaller species, P. angustifolia, Torr., was found at 

 over 11,000 ft., but so far, only on the other side — in Sagnache 

 County. 



Primula farinosa, L. — Years ago, I received an example 

 of this species, collected by Mr. W. West at Malham, Yorkshire, 

 Eng., and always regarded it as one of my most interesting 

 specimens ; but I had never found it growing until June 12th, 

 1888, when I quite unexpectedly came across it in flower by the 

 roadside near Ula. This seems to be the most southern locality 

 recorded for it in Colorado. 



Gentiana humilis, Stev.— In damp meadows ; begins to 

 flower about the middle of April. The flowers vary in colour 

 from nearly white (albescens) to blue (ccerulea). 



Gentiana serrata, Gunner. — Abundant and very conspic- 

 uous. Found also in Mesa and Summit counties.
