N. alba X Candida occurs in East Prussia at Neuhausen near Konigsberg, near 

 Goldap, and elsewhere (Caspary 1879). Sernander (1894) claims to have found a 

 red variety of N. Candida in Fagertarn, Sweden. 



Nymphaea nitida, Sims 181 1 a, with entire, suborbicular leaves, with obtuse lobes; 

 flowers white, cup-shaped, may belong here. Its habitat is unknown, and it has not 

 recently been positively identified anywhere. The figure of the Botanical Magazine 

 was " drawn at Mr. Vere's garden " in Kensington-Gore, Mr. Anderson, gardener. A 

 specimen exists in hb. Caspary (now Berlin), which was presented by Prof. M. T. 

 Masters in 1854 from the botanic garden of Oxford. Here it was received in 1840 

 from Kent, whither it came directly from Anderson. This specimen appears to belong 

 to N. Candida as here defined.

Leaves nearly orbicular, floating, red when very young, 10 to 30 cm. in diameter, 

 crowded on the rhizome, phyllotaxy about 13 on 34 ; lowest pair of veins straight and
