blotch at the top of the petal. From this point south to 

 Los Angeles County the forms seem to change frequently. 



At Preston and Newsom's Springs (San Luis Obispo 

 County) there is a pretty white form, in color exactly like 

 C. catalincB (white, tinged lilac), destitute of both eye and 

 rose-colored blotch, but with the ovate dark brown spot on 

 the claw of the petal, as in C. catalincB. 



At Santa Barbara the type with the rose blotch reappears, 

 and it is found at intervals southward. 



In the Ojai Valley and at Newhall there is a white-flow- 

 ered variety with a rose blotch and narrow petals, closely 

 resembling the white-flowered plants at Paso Robles. It is 

 also tall and slender. 



At Newhall a new color strain comes in, quite novel in 

 C. venusttis ; this (var. siil-pJmreus) is light yellow, narrow 

 petaled, and has the rose blotch. At Elizabeth Lake, a 

 point about midway between Newhall and Alcalde, the 

 species is again seen in the infinite variety of color found 

 about Paso Robles and in the southern Sierras, but with the 

 additional yellow form. 



Newhall is the most southern point from which the writer 

 has specimens of C . venustus. 



Mr. S. B. Parish has written a very interesting descrip- 

 tion of these color forms. 



The Eldorado strain, so termed by the writer in a cata- 

 logue of bulbs, is found in the Sierra Nevada. It begins 

 to appear a little north of Camp Creek (El Dorado 

 County), high up in the foot-hills in the upper Yellow-Pine 

 belt (growing oftenest in open woods), and extends at a 

 nearly uniform altitude in the Sierras south to the Tehachapi 

 and Tejon mountains. The colors of the flowers are richer 

 than those of the Coast Range forms. They vary from 

 white to lilac and deep purple, from pink to deep red, and 

 sometimes light cream flowers are found. The eye is dark 

 brown, not much oculated, the blotch at the top of the petal 

 varies from rose to gold, and flowers can be found with rose 

 or gold rays across the entire top of the petal; but the rose 

 blotch at the apex, instead of being a constant feature as is
