Cotyledon Purpusti is a native of the Sierra Nevada of 
California, where it was discovered at an altitude of seven 
thousand to eight thousand feet on Mt. Whitney, by the 
gentleman to whom it is dedicated by the author in the 
© Gartenflora.”” Nine Californian species of the genus _ 
are given by 8. Watson in the “ Flora of California,” with 
the descriptions of one of which, C. nevadensis, Wats., 
CO. Purpusii so closely agrees, that it is possible that the 
latter is a synonym, especially as Sonora and the Yosemite 
Valley (the habitats for nevadensis) are, though much 
lower in elevation, in the same botanical region and group 
of mountains as Mt. Whitney. Referring to the Her- 
barium, I find it impossible from dried specimens to settle 
this point, which must be reserved for study when living 
specimens of C. nevadensis are available for comparison. 
Another very similar species is Heheveria Desmetiana, L. de 
Smet (ex Morren in Belg. Uortic., 1874, p. 159; Ill. Hort. 
sér. 6, ii. p. 93, f. 13), which is recorded as a native of 
Mexico.
