drought remarkably well. Then follows a list of plants which have done 

 especially well ; of those which hardly flourish at all, such as Bamhoos 

 and most Australian Palms; and of plants which have perished from cold 

 or unknown causes. — W. C. W. 



Aconite, Winter, Smut attacking. By William Carruthers (Jour. 

 Ii.A.S. vol. lxii., p. 248, 1901). — An example of smut Urocystis anemones 

 was sent from Cambridgeshire. It had attacked winter aconite (Eranthis

 the order Ranunoulacea." — B. N. 



Adonis, Perennial. By G. Reuthe (Garden, No. 1583, p. 191 ; 



22 3/1902). — There is not a single species or variety of Adonis that does 

 not deserve to be cultivated. So states the writer of this article, and he 

 proceeds to describe the perennial ones and to give much useful cultural 

 and general information concerning them. — E. T. C.

Alabama, Plant Life of. By Oh. Mohr, Ph.D. {Contributions from 

 (he U.S. National Herbarium, vol. vi. 1901).— This work, of 846 pp. and 

 index of 75 pp., contains an account of the distribution, modes oi 

 association, and adaptations of the flora of x\labama, together with a 

 systematic catalogue of the plants growing in the State. 



After a sketch of the history of the earlier botanical explorations of 

 Alabama, the author deals with the general physiological features of the 

 State, geologically considered. 



The river systems are then discussed, and the climate, including 

 temperature, rainfall, winds, and cloudiness. 



Then follow the general principles of the distribution of plants, 

 Humboldt's and Merriams' " zones " being described ; the distribution of 

 species as depending upon geological history ; and plant formations and 

 plant associations of Engler and Drude. This part concludes with 

 Warming's new classification, followed by the present ecologists', viz. 

 bydrophytie, xorophytic, halophytic, and mesophytic vegetations. 



Then follows the general character of the Alabama flora. It stands 



the number of species and varietal forms, as well as in the diversity of 

 their characteristic associations, unsurpassed among those of adjoining 

 regions, such being due to its diversity of topographical features.
