CURRENT LITERATURE 
MINOR NOTICES 
A textbook of botany.—The second part of GANono’s Textbook of Botany 
has appeared,' including a presentation of the plant groups, and also the 
ecological classification of plants. In the first chapter the phylogenetic con- 
nections of the major plant groups are presented; while the subsequent 
chapters give a general account of the different groups, using selected forms as 
illustrations. The author is so well known as a teacher that it is hardly 
necessary to say that the presentation, following the ae he has had in 
mind, is thoroughly well done.—J. M. C. 
Manual of woody plants.—TRELEASF? has published a small pocket manual 
of the woody plants used for decorative purposes. The intention of the author 
“is to make it possible for any careful observer to learn the generic and usually 
the specific name of any hardy tree, shrub, or woody climber that he is likely 
to find cultivated in the United States.” The book contains 782 species in 247 
genera. Its keys and descriptions, with the help of the glossary, should enable 
those untrained in botany to recognize woody plants under cultivation in parks 
and other ornamental grounds; while its size makes it available as a pocket 
companion.—J. M. C. 
The sweet pea.—The rapid advance in plant pathology is bringing forth 
popular books on the diseases of special crops for the use of commercial growers. 
These works in order to meet the demand of the growers must be broader than 
most Experiment Station publications. The most recent publication of this 
ment Station have given him an especially good preparation for this work. 
The book gives a review of the history, evolution, and classification of sweet 
peas; a thorough discussion of cultural methods; and the diseases (including 
insect pests) and methods for their control. The work is very carefully pre- 
pared and well illustrated, and the discussions so clear and concise that the 
grower will find it very helpful—Met. T. Coox.
