America, descriptions and plates of eight new species of Crataegus, one of 
Malus, one of Solanum, one of Picea, and a new hybrid Cornus. There are 
also illustrations and descriptions of thirteen other species, previously 
described elsewhere.— 
THE CHARALES of the province of Brandenburg have been described by 
Holtz in an account of 136 pages which is well illustrated. This volume is 
one of aseries that is to treat the cryptogamic flora of this region. The 
account of the general structure of this group is very clear, the notes on 
distribution are full, and the arrangement good. It seems to be an excellent 
piece of work of its character— B. M. Davis. 
RINGLE AND KENOYER have attempted to meet the demand on the part 
of district-school teachers and high-school pupils for a simple means of 
determining the local spring floras The addition of laboratory hints, out- 
lines of morphology, and directions for the preparation of an herbarium, 
makes it more than a manual, but its subject-matter is wholly inadequate if it 
is supposed to comprehend the entire botanical pumnne of the high-school 
graduate. ma M. WESTGATE. 
AS A COMPANION book to Our Native Trees Miss Keeler® publishes a 
similar work on shrubs, The work contains very excellent descriptions of nearly 
all the native northern shrubs and many common cultivated ones. Accompa- 
nying each description is a well-made half-tone illustration of the form. In 
Many instances so good are these figures that they are sufficient to identify 
the plants. Each description contains many interesting facts about the habits 
of the shrub. A very simple key isgiven by which one who is not a profes- 
sional botanist may identify them. Indeed, the book is intended for the 
amateur, the lover of nature, and those interested in landscape gardening.—

THE LEGUMINOSAE collected in the states of Michoacan and Guerro in 
Mexico during the years 1898 and 1899 by Eugéne Langlassé have been 
elaborated by the late Marc Micheli? The purpose of Langlassé’s explora- 
tion was mainly horticultural and the collection of dried plants for the 
herbarium was purely incidental. Moreover, his collections of all kinds were 
Primarily of the plants having some interest for the horticulturist, or of impor- 
tance from the point of view of agriculture or forestry. In spite of this, the
