NYMPHAEACEAE. 

 THE MEXICAN WATERLILIES. 



For several years past I have been greatly interested in the Mexican 

 Castalias, having myself collected four of the -even species, one of 

 which ha- long borne tin unpublished name. When 1 learned some 

 years ago that Dr. Henry Conard was preparing a monograph of the 

 genus Nymphaea I withheld my note- from publication and turn< i 

 over the specimens to Doctor Conard for his inspection. Hi- mono 

 graph, an exhaustive treatise and beautifully illustrated, has recently 

 appeared. 



I have attempted here only to present a verv brief synopsis of our 

 Mexican species, referring the reader to Doctor Conard"- work for a 

 full treatment of them.
