THE MEXICAN WATERLILIES. 



I 



For several years past 1 liavo heen j^'i'catly interested in the ^Mexican 

 Castalias, having myself collected four of the seven species, one of 

 which has long borne an unpublished name. When I learned some 

 years ago that Dr. Henry Conard was preparhig a monograpli of the 

 genus Nymphaea I witldield my notes from publication and turjied 

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

 graph, an exhaustive treatise anci beautifull3' illustrated, has recently 

 appeared. 



1 have attempted here only to present a very })rief s3^nopsis of our 

 Mexican species, referring the reader to Doctor Conard's work for a 

 full treatment of them.
