Erythronium Hartwegi is very closely allied to E. grandi- 

 florum, Pursh.. of Washington Territory and Northern 

 California, of which the leaves are not mottled, the 

 perianth segments strongly recurved, yellow, or cream- 

 coloured, and the filaments longer and more slender. It is a 

 native of the Sierra Nevada, where it was discovered in 

 Butte County by Hartweg, and in Plumas County, and 

 other localities. 



The genus Erythronium, of which there are seven 

 generally recognized species, several doubtful, and many 

 spurious, is greatly in need of a careful study and 

 illustration by good drawings. This can only be effected 

 through cultivation, for the characters, of the flower espe- 

 cially, are more or less obliterated in herbarium speci- 

 mens. There are various obscure forms in North- 

 West America, which is no doubt the headquarters of 

 the genus, and I would strongly recommend them to the 

 attention of the Botanists, and especially the Botanic 

 Gardens, of California. 



The handsome species here figured has for a long period 

 been in cultivation at Kew, where it flowers in an open 



March 1st, 1898.
