My new variety of water lily, or nymphaea, belongs to the class known as tropical dayblooming. It was developed by me as the result of definite and extensive breeding. Its parentage is as follows:

N ymphaagc capensis N. castaliiflor N. ovalitolia N. capensis N. ovalifolia The first blossoms of this plant were produced in 1931. It hassincebeen reproduced asexuallyfrom bulbsand has not been offered for sale to the public.

The purpose of my invention is to provide a tropical day-blooming water lily of yellow color. This is the first tropical day-blooming water lily known that has yellow blossoms; heretofore the only known colors were white and various shades of pink and blue.

The accompanying illustration shows in full color a fully opened flower, a. bud with stem attached, and a leaf.

The following is a detailed description of this new variety of tropical day-blooming water lily:

Petioles terete green attaining a length of six feet when fully developed.
