Coulter, J. M.. C. R. Barnes and H. C. Cowles. A Textbook 

 of Botanv for Colleges and Universities. Vol. IL Eco- 

 logy. (8'\ p. 485-964. New York. 1912.) 



This volume by Henny C. Cowles treats of that phase of 

 ecology which may be called morphological and physiological eco- 

 logy, or the ecology of plant structure and behavior. It treats only 

 incidentally of physiographic ecology, or the ecology of Vegetation, 

 known also as antecology and synecolog3^ In the introduction 

 in referring to the terms used, the author emphasizes his point of 

 view by mentioning the terms to be avoided. Among such he in- 

 cludes words like adaptation , adjustment, accomodation and regu- 

 lation, as purposive words, and he replaces such usage by the 

 expression advantageous reactions. He makes the attempt to use words 

 that are applicable in physica and in chemistry, because ecology 

 more than any other phase of biology has suffered from the unre- 

 stricted use of anthropomorphic similes and teleological fantasies. 



Chapter I deals with roots and rhizoids under the captions soil 

 roots and root hairs, water and air roots, rhizoids. Chapter II dis- 

 cusses leaves with reference to Chlorophyll and food manufacture, 

 structure and arrangementof chlorenchyma, relation of leaves tolight, 

 air Chambers and stomata, protection from excessive transpiration, 

 variations in form, absorption, secretion and excretion, accumula- 

 tion of water and food, miscellaneous structure and relations. In a 

 similar detailed manner, the foUowing chapters treat of stems (chap. 

 III), saprophytism and parasitism, symbiosis 'chap. IV), reproduction 

 and dispersal (chap. V), germination (chap. VI), plant a.ssociation
