refer to the true waterlilies. He excluded the other two groups, but 

 omitted the coining of a new name for them. Surely this omission 

 cannot invalidate the name of the group which he did accurately 

 describe. 



Linnaeus's definition of Nymphaea of the sixth edition of the Genera 

 Plantarum was copied verbatim in the various 7th and 8th" editions. 

 It was accepted and amplified by Jussieu in his Genera Plantarum 

 (1789). There we read, p. 08, 



Nymphaea, T. L. * Nenuphar. Calix multipartitus laeiniis inul- 

 tiplice ordine, cxterioribus 4-5 extus viridibus, caeteris interioribus 

 (petala T. L.) coloratis, petaloideis. Stamina numerosa, multiplici 

 ordine germinis lateribus affixa; filamenta exteriora latiora et peta- 

 loidea; etc., etc. 



Jussieu called all of the perianth a calyx, whose inner members are 

 colored and petaloid. The numerous stamens are attached to the 

 sides of the ovary, and the outer have broad, petaloid filaments. All 

 of these characters apply only to the white waterlily group, and not at 

 all to the cow-lilies or the lotus. If, therefore, any doubt remains as 

 to the meaning of Linnaeus's Nymphaea, no doubt can remain regard- 

 ing Jussieu's. When we add that Adanson in 1763 1 had separated 

 the genus Nelumbo from the original Nymphaea of Linnaeus (1753- 

 54), we have the facts as they were when Salisbury wrote. 



Salisbury in 1805 completed the segregation of the old genus Nym- 

 phaea along lines already pointed out by Linnaeus. But he was 

 entirely wrong in applying Linnaeus's amended name Nymphaea to 

 the part of the genus which Linnaeus had definitely excluded from his 

 mature generic characterization, and in coining the new name Castalia 

 for the group, which both Linnaeus and Jussieu had clearly intended 

 in their descriptions of the genus Nymphaea. A comparison of 

 Salisbury's generic diagnosis with those quoted from Linnaeus and 

 Jussieu will show how he reversed the meaning of Nymphaea. He 

 says (Konig and Sims Ann. of Bot. 2: 71, 1806), 



NYMPHAEA 



Calyx 5-0-phyllus, toro insertus, petaloideus. Nectaria 11-10, 

 toro inserta, lamellaria, dorso mellifera. Filamenta 90-100, toro 

 inserta, sub anthesi a pericarpio elastice dissilientia, etc.
