 forms in growth. The technical illustrations are clear and very 

 well represented. 



Dr. Howe's treatment of Hepaticae has also a wealth of illus- 

 trations including many halftone pictures as well as line drawings. 

 An illustrated glossary of special bryological terms is a valuable 

 feature both for the individual student who wants to become 

 acquainted with some of the native Hepatics and for class work.

The Native Flora of the Vicinity of Cold Spring Harbor, 



L. I., N. Y.* 



This work should be of great interest and value to any botanist 

 who may wish to study the plants of the Cold Spring Harbor (N. 

 Y.) region, as either a systematist or an ecologist. Preliminary 

 chapters on the geology, soils and climate of Long Island, which 

 are written with special reference to the region around Cold 

 Spring Harbor, serve as a background for the understanding of 

 the floristic characteristics to which they give rise. The great 

 variety of habitats found in morainic ridges, alluvial plains, 

 prairies, bogs, salt meadows, estuaries of all degrees of salinity, 

 lagoons, littoral dunes and boulder strewn beaches affords an 

 unusually large number of ecological types for so limited an 

 area. 



The list of species, which constitutes the major portion of the 

 work, is particularly broad in scope, although the author does 

 not claim completeness, especially in the lower divisions of the 

 thallophytes. "Die Natiirliche Pflanzenfamilien" and the "Syl- 

 labus der Pflanzenfamilien" (1919) form the basis for the taxo- 

 nomic sequence of the cryptograms, (exclusive of Pteridophytes), 

 used in this paper, while the arrangement of Britton and Brown's 

 "Illustrated Flora" is followed for the Pteridophytes and seed 

 plants. The list includes 1865 species of living plants, belonging 

 to 991 genera and ranging from the bacteria to the composites. 

 With a few exceptions among the lowest forms, the author gives
