THE AMERICAN NATURALIST [Vol. XLl 



An excellent, conservatively handled, local flora, of a very rich region, 

 is that of the State of Washington, by Professor Piper, recently pub- 

 lished as vol. 11 of Contributions from the U. S. National Herbarium, 

 an illustrated volume of 637 pages. 



In contrast with the highly diversified flora of Washington, is the 

 homogeneous flora of the Altamaha grit region of the coastal plain of 

 Georgia, to which is devoted a volume of 357 pages, by R. M. Harper, 

 forming vol. 17, part 1 of the Annals of the New York Academy of 

 Sciences. In this region, comprising about 11000 square miles, only 

 814 species or varieties of vascular plants are recognized, and 75 of 

 these are weeds. Mr. Harper's study has been carried out on the lines 

 of ecological analysis with special reference to geographic distribution, 

 and his paper is illustrated by a map and 28 half-tone plates which 

 form one of the best series of such illustrations yet published. 



Habit illustrations of antarctic vegetation are given by Skottsberg 

 in Reihe 4, Heft 3-4 of Karsten and Schenck's Vegetationsbilder. 



Further "Contributions to Canadian Botany" are being published 

 by IVIacoun in current numbers of The Ottawa Naturalist. 



The official precedings of the International Botanical Congress 

 held at Vienna in 1905 have recently been issued from the Fischer 

 press of Jena, in the form of a quarto brochure of vi + 262 pages: 

 the scientific papers presented before the Congress form a similar 

 quarto of vi-|-446 pages, freely illustrated, and published by the 



A polyglot code of the rules of botanical nomenclature adopted by 

 the 1905 International Botanical Congress of Vienna, has been sepa- 

 rately issued from the Fischer press of Jena. The pamphlet is indis- 

 pensable for every phanerogamic herbarium. One of the most debated 

 acts of the Congress was the adoption of a list of several hundred 

 generic names which were considered so thoroughly established as to 

 be exempted from supersession by earlier names which have failed to 

 come into general use. This list is included in the pamphlet. 



Professor Bray's " Wgc^tatioii ..f the S,.tol Country in Texas," 

 elsewhere published, is also printed in vol. 7 of the Transactions of 

 the Texas Academy of Sciences.
