36 THE PLANT WORLD 



The plants of Western Lake Erie, with notes on their distribution, 

 is the subject of an interesting paper by Mr. A. J. Pieters [Bull. U. S. 

 Fish Com, for 1901]. He divides all the plants into two groups : one 

 including all submersed forms and those with floating leaves, and the 

 other all remaining species with emersed leaves and growing with roots 

 and parts of the stem in water. About 160 species are treated and full 

 notes given as to their habits, internal structure, etc. 



Professok Aven Nelson recently began the publication of a series 

 of descriptive papers on western plants under the title of Contributions 

 from the Rocky Mountain Hebarium. The second number contains 

 descriptions of new Colorado Species, Western Eupatoriae, and Studies 

 in Arnicas. 



F. Jaennicke has recently published a valuable paper [Abhandl. K, 

 Leopold, Carolin. Dent. Naturf., 77, No. 2,] on the genus Platamis. 

 The author gives results of 5 years' study on this genus, and among his 

 conclusions he states that there are 6 species and 11 varieties, as follows : 

 P. orientalis, with 4 varieties ; P. occidentalis, with six varieties ; P. 

 acerifoUa, which he believes may prove to be either a variety of occideyi- 

 talis or possibly a hybrid between P. occidentalis and P. orientalis ; P. 

 racemosa ; P. 3Iexicana, with 1 variety, and P. Wrightii. The second and 

 last three species are of American origin. 



The latest number of the contributions from the U. S. National 

 Herbarium [Vol. VII., No. 3] by V. K. Chesnut, is devoted to the plants 

 used by the Indians of Mendocino County, California. The author has 

 spent portions of four or five seasons in making these inquiries into the 

 native uses of plants, and he has brought together a large amount of very 

 interesting and valuable information. The plants mentioned are 

 arranged by families. After the Indian name follows the mode of prepara- 

 tion and uses to which the various species of plants are placed. The 

 paper is quite fully illustrated, the figures showing cei"tain of the more 

 important species, as well as the finished products made from them by 

 the natives. 



With the beginning of the year The Forester, the organ of the 

 American Forestry Association, was merged with National Irrigation, 

 the organ of the National Irrigation Association, under the heading of 

 Forestry and Irrigation. The January number contains articles cover- 

 ing both fields and is fully illustrated. 



Among the forthcoming publications of the Clarendon Press, may 

 be mentioned an authorized Translation of Schimper's Geography of 

 Plants, by Percy Groom, M. A., and W. B. Fisher, B. A. We shall give 

 an extended notice of this valuable work later.
