EOSE — MEXICAN AXD CENTRAL AMERICAN PLANTS. 95 



Typ^ V. S. National llerl>anuiu uo. 461981, collected by Dr. G, G. Pringle in Lake 

 XocliiinilcOj Valley of Mexico, 1896 (no. 6464); also in tlie same lake by J. N. Rot^e 

 ainl Walter Hough, :\Iay 26, 1899 (no. 4830). 



Doctor Conard refers tliiy species to Nijufpltaea od(frata {/{(jnttfra, the ** types'' of 

 which, he states, came from Saint Georges, Delaware. Even if Doctor ConanTs 

 reference were correct the name Avould be untenable, as there in aln^ady a Nymphaea 

 glyunltci. 



Castalia odorata (Ait.) Woodville & Wt^od, Kees' Cy('lo]:>edia 6: no. 1. 1806. 



Nijmphnea odoratit Ait. llort. Kew. 2: 227. 17S1). 



To ('. odorata 1 have refernHl witli ponic doubt material collected by Dr. E. Palmer 

 near Durango in 1806 (no. 244). Thi.s statiun, however, is so far away from the 

 known range of C. uihyndUy that species having not lieretofore been reported from 



anywhere in Mexico, that its inclusion iu the Mexican flora can at present be only 

 tentative. The powsibihty of the species having been introduced into ponds Laa been 

 su<rgested, but Dr. Pahner assures me that the plant shows every indication of being 



CG 



a native.
