well-known morphological principles are thus beautifully 

 illustrated in one flower. 



The close affinity of Nelumbo with the apocarpous Nym- 

 phseas (N. cceriilea, N. zansibariensis, N. gigantea, etc.), is 

 also suggested. The stamens of N. gigantea, the most 

 primitive member of the genus, closely resemble those of 

 Nelumbo in the slender filament and curved anther. The 

 receptacle, too, of Nymphaea is a cup-shaped organ, to the 

 inside of which the backs of the carpels are fused, and on the 

 outside the stamens are attached.
