Nuphar variegalum, Engelmann, is referred by Gray as a variety of this species. 



DeCandolle and Salisbury both quote, as belonging to this species, the Nyviphcca flori- 

 bttsjlavis of Clayton, in the Flora Virginiea of Gronovius, " ed 1, p. 164." I have not been 

 able to refer to that edition, but find neither the name, nor any corresponding plant, in 

 the second edition of 1762. 



3. — N. Fletcheri X- Nvphar advena X Kalmianum, Caspary, MS. Macoun, Cat. 

 Can. PL, p. 32, (1883). Fletcher, Flora Ottawaensis, p. 62 (exc. syn. N riibrodiscum) . Mr. 

 Fletcher describes this hybrid, which he found in tln^ Ottawa River, as intermediate in 

 size and appearance between Nvphar advena and Kalmianum, the floating leaves purifie 

 beneath, with slender petioles, the submerged ones freely produced and like those of the 

 latter species ; expanse of flowers IJ inches, sepals 6, stigmatic disc 10-15-rayed, the 

 perfect fruit, which is seldom produced, bearing a closer resemblance to that of Kalmianum 

 than of the other parent. Prof Caspary, to whom living plants were sent, found the 



' The generic name Nujihar, a neuter noun, was long treated by Smith, DeCanJolle, and European botanists 

 generally, as feminine- In quoting references, I bave not thought., it necessary or desirable to keep up the 

 feminine terminations given by the authors quoted to the adjective terms. The change to the neuter gender 

 appears in Walpers' Annates, torn. IV, fasc. 2, published in 1857, after which corrections of names come slowly into 

 botanical works ; the earliest instance of correct u.?e tliat I can find is in Kocli'.s Synopsis' FIor;u Germanicic et 

 Helveticîe, 2nd ed. , published in 18-13. His first edition, I have not been able to refer to.
