sprinkled with the spice of poetry, is a consideration of the root, 
stem, leaf, flower, and fruit of weeds, thus preparing the student 
along strictly botanical lines for the use of the descriptive catalog 
that makes up the main portion of the work. As a rule the 
species—arranged by families according to Britton and Brown's 
Flora—are illustrated by cuts well chosen from many sources. 
It is quite clear from this little book—deserving more than a 
paper cover—that weeds provide a subject of great variecy for 
the study of plants in the many phases of their existence, whether 
that extends over only a few weeks or through many years. 
While written especially for Indiana the author has provided a 
handbook from which any one can gain an interesting and profit- 
able familiarity with many of our more common plants.—B.

370. ap. I9I2.—Kwangtung contains about 68,000 square 
miles, about one half within the tropics. There is a moderate 
range in elevation, from sea-level to 3,000 feet, with a few higher 
mountains about which little is known. The area of Hongkong is 
only 30 square miles, largely hilly, but it has been carefully 
explored. Many parts of the mainland are imperfectly known, 
especially in the southwest; nevertheless, its flora has been more 
accurately ascertained than that of any other part of China. It

The sequence and limits of families are those of Bentham and 
Hooker; had Engle: and Prantl been followed, the number of 
families would be stated as 181. In practically all cases, the 
authors have adhered to the nomenclature of the Index Kewensis.
