White-fruited forms of G. resinosa are mentioned in our man- 

 uals of botany, and the red may also have been detected before. 

 They are analogous to cases more often occurring in the common 

 blueberries. I have several times come upon Vaccinium vacil- 

 lans, with white or pinkish fruit, in the dune region of northern 

 Indiana. Sometimes the bushes will almost or quite exclusively 

 occupy an area of one or two square rods, producing berries of 

 these abnormal colors which can be gathered by the quart.

Curtis's Nature and Development of Plants* 



In this work the author has " had in mind a purpose to make 

 familiar our common plants," this knowledge being considered 

 fundamental in any botanical work. The volume is not offered 

 as a text, but as a reader to accompany lectures and laboratory 

 work. Pedagogically the object is to " quicken the reasoning 

 faculty, and create a desire for a further examination of the 

 subject." 



The Introduction discusses, (i) The Nature of the Plant (as 

 made up of cells) ; (2) The Nature of the Living Substance of 

 the Plant. The four sections of Part I, Nature of Plants, treat, 

 in order, of the leaf, the root, the stem, and the flower, fruit, and 

 seedling. Part II, The Development of Plants, comprises six 

 sections, dealing with, Classification of Plants, Thallophyta, 

 Bryophyta, Pteridophyta, Spermatophyta, Angiospermae (Sper- 

 matophyta concluded). Two hundred and forty-four pages are 

 devoted to Part II, and ninety-four to Part I. 



In conformity with the aim, familiarity with common plants, 

 physiology is given less prominence than structure and classifica- 

 tion. There are no illustrations of physiological experiments. 

 On reading through the chapters, one's attention is arrested by 

 the use of pistil and carpel as synonymous (p. 102) ; of anther- 

 idial cell for the more usual term generative cell (p. 108) ; and
