470 © BOTANICAL GAZETTE [DECEMBER 
Among the names in the second bibliography one finds those of BuRGER- 
STEIN, CZAPEK, FRITSCH, HABERLANDT, KRASSER, LINSBAUER, MIKOSCH, 
Mo tiscH, WETTSTEIN, ZAHLBRUCKNER, and others—certainly a notable list. It 
has been a pleasure to many American botanists to meet Professor WIESNER this 
summer and to join in the congratulations upon his past labors and extend to him 
our best wishes for the future.—C. R. B 
MINOR NOTICES. 
FritscH has published an interesting contribution to the comparative mor- 
phology of the seedling of Gesneriaceae.*° The account is so largely a description 
of many forms that a satisfactory summary is difficult to give. The book is 
divided into two parts. In the first part twenty-six species, comprising fourteen 
genera, are treated, and the gross form, particularly in several species of the Strep- 
tocarpus, is described in considerable detail. In the second part the structure 
of the grown plants is considered, and the behavior of the cotyledons, leaf arrange- 
ment, anisophylly, and kindred topics presented by this group are discussed. A 
chapter is devoted to a short account of the anatomy of Gesneriaceae and one 
also to the structure of Steptocarpus as compared with other Cyrtandroideae.—

THE HortIcuLtuRAL Society of New York has published"! the proceedings 
of the International Conference on plant-breeding and hybridization held in New 
York city, September 30 and October 1 and 2, 1902. The conference was such a 
notable one in the quality of the papers presented that it is a valuable service to 
biology in general to have them accessible. Not only are the presented papers 
published, but also the discussions and the papers read by title. Forty-two papers 
are thus brought together, most of them dealing with the fundamental principles 
of plant-breeding and hydridization, and they represent investigations and con- 
clusions that botanists should become more familiar with—J. M. C. 
Lrypav” has published a pocket handbook for the collection and preparation 
of the lower cryptogams with special reference to conditions in the tropics. In 
this work of some 75 pages the characteristic habitats of mosses, liverworts, 
algae, and fungi are described; directions are given for the preparation of material 
in herbarium form and for the simpler methods of preserving in spirits or in 
formalin. It is a book which the traveler and collector with botanical interests 
will find very useful—B. M. D
