Nomenclatorial Principles. By M. l^. Fernald {Bot. Gaz. vol. xxxi. 

 p. 188 ; No. 3). — Gives an account of some recent publications bearing on 

 this subject, as Heller's " Catalogue of North American Plants north of 

 Mexico " (1900-1), which is criticised ; Professor Underwood's " Our 

 Native Ferns and their Allies"; Britton and Brown's "Illustrated 

 Flora" ; and the Botanical Club's " Check List " of north-eastern plants. 

 These are compared and synonyms criticised, and numerous inconsist- 

 encies as to the treatment of species by the authors are pointed out.

Nuts. By John R. Parry (i7.>S..4. St. B d. JRhode IsL). —CheHtmiiH 

 succeed best on high well-drained spots and in soil of a sandy nature. 

 They yield as many bushels an acre as Wheat does and at vastly less 

 trouble and expense. They can be ground into flour that makes very 

 superior bread. The writer prophesies that they will "inevitably" 

 supplant wheat before long. 



The Chinquapin is like a small Chestnut, but makes up for its lack of 

 size by its productiveness and by the fact that it will bear a temperature of 

 20 deg. below zero ; its flour is also even sweeter and more delicate than 

 that of Chestnuts. 



"Walnuts. — A large number of species and varieties are discussed, the 

 palm being given to the Japanese Juglans cordiformis, which is said to 

 be "of inestimable value." 



Many varieties of the Hickory are also discussed, their kernels being- 

 said to be in great demand among confectioners. — TF. W. 



Nymphaea flavo-virens, Lehm. By Sir J. D. Hooker {Bot. Mag.
