 L. (Villarsia) nvmphaeoidcs Hoffmgg. et Link, S. England, is a water- 

 plant with habit of Nymphaea. The infl. appears to spring from the 

 top of the leaf-stalk, but really the floating 1. springs from the infl. 

 axis. This is an advance upon the Nymphaea construction, as the 

 materials going from 1. to seeds have not to travel to the bottom of 

 the pond and up again.
