As already stated, Sir James Smith, in 1808 or 1809, adopted Salisbury's division oi' 

 Nymplum, but uot his nomenclature, retaining the name Nympliaa for Salisbury's Castalia, 

 and giving the new name Nuphar to the yellow-flowered species. 



In his paper in the Journal of Botany, Mr. Britten has revised the gener i Castalia, 

 Salisb., and Nymphcea, Salisb., and given a Synopsis of the "correct nomenclature" of the 

 Salisbury species, noticing the difficulty in regard to Salisbury's Castalia mystica, on 

 account of its including three plants, which Mr. Britten assorted as follows : — 



C. mystica, Salisb.(the Egyptian and African N. Lotus.) 

 C. sacra, Salisb. in Paradisus, (the Indian, N. Lotus.) 

 C. ihermalis, Britten (the Himgarian, C. mystica.) 



Prof. Greene followed up Mr. Britten's readjustment of the Castalias (Torrey Bulletin, 

 Marcli, 1888, XV, p. 84), by renaming several North American species that the latter had 

 uot taken up, as follows : — 



Nuphar polysepalum, Engelm. = Nymphœa polysepala, Greene. 

 N. rubrodiscum, Morong. = Nym. rubrodisca, Greene. 



Nymphfea tuberosa, Paine. = Castalia tuberosa, Greene. 

 N. flava, Leitner. = C flava, Greene. 



N. elegans. Hooker. = C. elegans, Greene. 



Not being aware that the proper specific names of Castalia alba and odorata had been 

 reestablished by Woodville and Wood, Prof. Greene also proposed the reinstating of 

 these specific names under the new generic term, in correction of Salisbury's " wrong- 

 doing " in changing them respectively to speciosa and pudica. 



The Genus Castalia, Salisbury. 



The points at issue having been indicated, and mention made of the work of Prof. 

 Greene and Mr. Britten in reviving Mr. Salisbury's neglected generic names, and revising 

 the specific nomenclature accordingly, it is desirable here to give some history of the 

 genus Castalia, and of its species, that have so long stood under the generic name 

 Nymphœa. 



The following table will show the equivalence of the generic name Nymphœa as 

 used successively by leading systematists. The Nymphœa of Tournefort, Jussieu, and 

 Willdenow, included the Castalia and Nymphœa of Salisbury ; Nymphœa of Linnœus, and 

 Hunberg, included Castalia, Salisbury, Nymphœa, Salisbury, and Nelumbo, Tournefort, 

 which last was called Cyamus by Smith and Salisbury ; Nymphœa of Smith, and of 

 Bentham & Hooker, is equivalent to Castalia, Salisbury ; Nymphœa, Salisbury, Greene, and 

 Britten, is equivalent to Nuphar, Smith : —
