Correspondence and Comments Subsequent to Initial Analysis
Correspondence 1 9 Sep 2002 e-mail from Jeff Greenhouse see Comment 1
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)]. [According to Jeff Greenhouse, pers. comm., none of the minor variants in The Jepson Manual [Ed. 1] is addressed in the cited literature.]
