TENDER \YMPA:HAS. day BLOOMIXG. 91 



It is worthy of special note as beinjj the only white day-blooniing tropical or 

 tender species; a very vigorous plant, free flowering, the flower possessing a 

 delicate fragrance, resembling Lily of the Valley. (See plate facing page 24.) 

 N. mexicana. This is possibly a form of N. flava, which it resembles in 

 most respects. The habit is the same, but the runner plants not infrequently 

 produce flowers during the first season. The plant is altogether freer flower- 

 ing, and the flowers are brighter and deeper in color. The plant is the same 

 in hardiness as N. flava. 



STKLI.ATE FORM OF NVMPH.tA. 



Seudling of N. gracilis. 



N. pukherrima. Very vigorous and free flowering; possibly no other 

 equals it. The flowers are very large under high cultivation — ten to twelve 

 inches across — of a beautiful light blue, with deep yellow stamens tipped blue; 

 the sepals are irregularly striped dark red. Unlike N. zanzibarensis, this 

 variety opens its lovely flowers at early morn, and remains open until other 

 species are mostly closed. The leaves are large, and often exceed two feet in 

 diameter, having long tapering lobes and irregularly crenated margin. Garden 

 hybrid of American origin.
