Editorial Comments 1 Correspondence 1 indicates that morphological and molecular data (e.g. Clary, K. H. and B. B. Simpson, Bol. Soc. Bot. México 56: 77-88, 1995) support recognition of Yucca whipplei in a separate genus, as Hesperoyucca whipplei (Torrey) Trelease, published in Rep. (Annual) Missouri Bot. Gard. 4: 208. 1893 [authors and places of publication discussed by Greenhouse and Strother (Madrono 49: 20-21, 2002)].
Correspondence 2 Treatment and author notes submitted for The Jepson Manual [Ed. 2] by William J. Hess see Comment 2
