1902] Rich, — Lists of New England Plants, — IX 



203 



an annotated list of the fern and seed plants, which grow without 

 cultivation in the area covered. Under each species and variety the 

 scientific name is followed by a careful statement of the peculiar 

 habitat, abundance, time of flowering, and finally the citation of one 

 or more numbered herbarium specimens. Common names, notes as 

 to habit, and a judicious synonymy are added in many cases. Sta- 

 tistical summaries, including a comparative table showing the numer- 

 ical relation of the flora of Southington to that of Vermont, appear 

 at the end, together with a map and good index. Although the ter- 

 ritory covered contains but thirty-six square miles, no less than 

 twelve hundred and one plants are enumerated. The authors show 

 themselves familiar with the latest taxonomic work in America and 

 treat with excellent discrimination the recently proposed species 

 which happen to come within their limits. The authors' "invariable 

 rule has been to admit no name that has not an extant specimen 

 back of it." The work throughout shows exceptional care in 

 arrangement, typography, and proof-reading. It is safe to say that 

 no more critically prepared flora of so limited an area has appeared 

 in America. While the authors have scrupulously avoided making 

 new combinations, they have introduced the following herbarium 

 names, to which it may be well to direct attention : Aster macrophyl- 

 lus, var. ianthinus, Fernald (A. ianthinus, Burgess), and Cirsium altis- 

 simum, var. discolor, Fernald {Carduus discolor, Nutt.).
