In DRYER’s new “ Lessons in physical geography’? we are pleased to 
notice a fuller account than is usual in such books under the topic “ Plant 
geography.” It is refreshing to see some of the more cogent ecological facts 
presented in place of the time-worn statements current in the older physical 
geographies.— H. C. Cowes.

THE FIRST FASCICLE of the fifth volume of Thomé’s Flora von Deutsch- 
‘and, dealing with cryptogams, has appeared, with Dr. Walter Migula as 
author. The pteridophytes appeared in the first volume, so that the present 
one begins with the Bryophytes. A general discussion (21 pp.) of the essential 
features of the group, illustrated by the excellent plates, precedes the sys- 
tematic presentation. The fascicle includes the Sphagnaceae, comprising 
22 species of Sphagnum, and also the beginning of the Andreaeaceae.—

Dr. Eve. WaRMINGS has published his sixth contribution dealing with 
Podostemaceae, Presenting the genera Polypleurum, Cladopus, Griffithella, 
Sphaerothylax, Tristicha, and Marathrum. The very full and illustrated 
account of the anatomy, morphology, and distribution of these interesting 
forms follows the method of the preceding papers, which appeared in the ~ 
—— publication in 1881, 1882, 1888, 1891, and 1899. In another contribu- 
tion the author promises to present a systematic revision of the family, based 
upon these studies.— J. M. C.
