136 The Waterlilies. 



The true species (var. Plumieri Planch., etc.) is of powerful growth, but has 

 not yet been introduced into cultivation. We have discarded the varietal name in this 

 and in other species, allowing the specific name alone to stand for the form originally 

 described. 



Var. speciosa (Mart. & Zucc.) Casp. 



Of medium size; stamens 42 to 129; leaves less coriaceous, margins more or less 

 repand-sinuate or dentate, with obtuse teeth ; nerves slightly prominent beneath ; lobes 

 divergent, overlapping or approximate. Tuber sub-globose.

Notes. This is the form cultivated in Europe as N. ampla, sent to Kew from 

 Jamaica by Macfadyen in 1847 or 1848, and to Caspary from Caracas by Dr. Ernst 

 in 1869. 



Specimens from St. Christophe and Maracaibo have the lobes of the leaf widely 

 divergent; those cultivated in Europe from Jamaica stock have the lobes touching; 

 nearly all the others in collections have an open but very narrow sinus. 



The type specimens of N. ampla y Salzmanni Planch, and N. tropaeolifolia Lehm. 

 consist each of a flower of this variety with a leaf of N. rudgeana Mey. (Casp. 1878). 



Var. pulchella (DC.) Casp. 



Flowers of medium to small size ; stamens 30 to 50 ; margin of leaves sub-entire 

 or slightly repand-sinuate ; veins slender, scarcely prominent.
