422 EXPERIMENT STATION RECORD. 



abridged so as to bring the subject-matter within the compass of a single vohime. 

 The systems of arrangement and nomenclature of the previous publication have been 

 retained. References are given to the figures in the Illustrated Flora, and the only 

 synonymy quoted is that made necessary by changes resulting from further studies 

 of the nomenclature of many species. By the use of thin paper, narrow margins, 

 and small clear type, the publishers have produced a compact volume that will be 

 preferred by many to the 3 bulky volumes of the original publication. 



American grasses, II, F. Lamson-Scribner {U. S. Dej)t. Agr., Dwision nf Agros- 

 tology Bui. 17, rev. ed., pp. 349, jigs. 32.5). — This is a revised edition of a bulletin pre- 

 viously mentioned (E. S. R., 11, p. 219). In the present publication the synonymy 

 has been revised and extended, and many of the descriptions have been entirely 

 rewritten and considerably extended so as to include brief economic notes which 

 were omitted from the jirevious edition. 



Plant life of Alabama, C. Mohr {U. S. Dept. Agr., Division of Botany, Contribu- 

 tions from the U. S. National Herbarium, vol. 6, pp. 921, pis. 13). — This publication 

 gives a description of the plant life of Alabama as observed by the author during a 

 40-year residence in the State. A short sketch is given of the physiographical 

 features of the State and on the general aspect of the flora of Alabama, its relation 

 to that of adjoining States, and to the continental and extra-continental floras. A 

 general discussion is given of the geographical distribution of plants, the floral divi- 

 sions of the State introduced by the author being considered as only tentative. The 

 general and secondary factors influencing plant distribution are mentioned and vari- 

 ous plant formations and associations are described. Following this is given a com- 

 plete enumeration of the plants, nearly 4,500 species and varieties being given. The 

 distribution of the species in the State is indicated, and descriptive and economic 

 notes given of many. 



The g-enus Salix in Iowa, C. R. Ball {Contrib. Dept. Bot. Iowa State Col. Agr. 

 and Mech. Arts, 1900, No. 18, pp. 141-154, pl^- 3). — An enumeration is given of the 

 willows known to occur in Iowa and the distribution of the different species through- 

 out the State is indicated. 



A monograpli of the genus Melilotus, O. E. Schulz {Bot. .Tahrb. [Engler}, 

 29 {1901), No. 5, 2Jp. 660-735, pis. 3). — A historical sketch is given of the genus and 

 statements made concerning the economic value of some of the species. The morphol- 

 ogy of the different parts of the plant is described and the geographic distribution of 

 the species indicated. In all, 2.3 species are recognized. 



A contribution to the knowledge of the Chjrtridiaceae, R. Ltim {Inaug. 

 Diss., Bern, 1900, pp. 44-^2, figs. 5). — The first part of this dissertation is given up to 

 a description of Synchytrium drabpc, n. sp., in which its morphology and affinities are 

 discussed. In the second part the ])iological relationship of a number of species of 

 Synchytrium is discussed, particular attention being given to S. taraxaci. The 

 results of many inoculation experiments with this fungus are reported and discussed, 

 from which the author has decided that ^S'. taraxaci is not only morphologically 

 distinct, but also biologically. In this group the species seem to be more sharply 

 differentiated and specialized as to host plants than is usually the case with related 

 fungi. The results of studies on the resting spores and other means of propaga- 

 tion are given in conclusion, the principal studies being made with Cladochytrium 

 meyiyanthis. 



Anatomical characteristics of agarics, J. Godfrin {Bnl. Soc. Sci. Nancy, 3. ser., 

 1 {1900), No. 6, pp. lSS-211, figs. 17). — Describes the anatomical structure of a 

 number of species of Panteolus. 



Inventory of foreign seeds and plants, J. G. Smith ( U. S. Dept. Agr., Section of 

 Seed and Plant Introduction, Inventory No. 8, pp. 106). — This inventory includes the 

 seeds and plants imported for distribution in cooperation with the various experiment 

 stations in the country, describing numbers 3401 to 4350, inclusive. Most of these
