The perennial forms of Phi/saJis are referred to P. Virginica, Mill., instead of 

 to P. viscosa, Linn., and to P. lanceolata, Michx.. in place of F. Pennst/lvanica, L. 



Gsntiftna detonso -becomes G. serratn, Gunner, and var. linearis of G. Saponaria

Forsternnin diffnrmis is transferred, with some doubt, to Trachelospermum, Le-

Acerates paniculnta is referred to AscUpiodora, a genus proposed by Dr. Gray 

 for all the later species of Anantherix, Nutt.. which is restricted to the single species 

 upon which it was founded.

'•Ferns of Kentucky, with sixty full-page Etchings and six Wood-cuts," 

 etc.. by John Williainsnn. — Louisville, John P. Morton &, Co., 1878.— 



The desire of the author of this work was to make fi little hand-book, wliich 

 the Fern-lovers of Kentucky would eairy with them in their excursions, and 

 which would enable them to easily recognize the ferns they might meet with. 

 The descriptions of the species are given in popular language, as far as is possible, 

 and every plant is illustrated by an etching made by the author's own hand. A 

 few intioductory chapters treat of the general nature of ferns, and of their struc- 

 ture, fertilization, classification, and the methods of collecting and drying or of 

 cultivating them. The whole is written in clear, simple English, and makes a 

 very readable book, which is certainly well adapted to the end desired. The au- 

 thor gives localities for all but the ver}^ commonest species, and very often there 

 is a useful hint as to the best mode of cultivating some particular species. The 

 etchings are mostly very characterist'c of the species, and the author is certainly 

 to be commended for Iiis ingenuity in representing a large fern on a small plate. 

 If I have counted them correctly. Mr. Williamson gives forty species as found in 

 Kentucky, including two, Asplenium Bradleiji and '/ richomanes radicans, which are 

 not given in Gray's Manual, and omitting, as not native to his State, about eigh- 

 teen or twenty, whicli occur in various parts of tlie Northern States. Of course, 

 such northern ferns n^ Aspidium frin/rans and ^4. Lonchitis, Woodsia glabella and W. 

 lujperborea, are not to be expected in Fventucky, nor of course the New Jersey 

 Schiscea, or the Northwestern Allosonis acr"stichoides; but one would have supposed 

 that Strnthiopteris Germanica might occur in Kentucky, and perhaps Woodwardia 

 Virginica. It is almost safe to promise that diligent search in the south-eastern 

 counties will bring to light Aspleninm parrulinn, while Phegopteris Dryopteris and 

 one or more of the little Botri/chia may possibly lurk in some cool recess of the 

 Cumberland mountains. At any rate, if they are there, we may be very sure that 

 so enthusiastic and pains-taking a Ptcridologist as Mr. Williamson will be sure to 

 find them.— Daniel C. Eaton, .Vr-io Haven, Jubj 22, 1878,

 were crowded out by other matter. They will appear in the December number.—
