in sections 2 and 3 of the paper. In this part one regrets the absence 

 of plates, which we hops the author may yet be enabled to add. 



The whole number of species in the world is stated to be " per- 

 haps forty to sixty," of which fourteen, besides a dozen well- 

 marked varieties, occur in North America. It may be of interest 

 to enumerate those occuring in this country, giving the geograph- 

 ical range, as indicated by specimens.

Modern Botany and Mr. Darwin.— In no one thing is the bot- 

 any of to-day more sharply in contrast with that of a quarter cf a 

 century ago than in the attention now given to the study of plants as 

 Hvincr things. The plant as a body of a certain form, occupying a 

 definite amount of space, does not now absorb the whole atten- 

 tion of the botanist. For the botanist of to-day, plants are living, 

 moving, feeling beings, whose habits and movements, and the 

 secrets of whose lives are deemed worthy of the closest scrutiny 

 and observation. In this work, the proper work of modern bot- 

 any. Mr. Darwin led, and where he did not enter himself, he 

 pointed out the way. The titles of his books alone, almost out- 

 line the whole work of the student of plant life. The " Contri- 

 vances by which Orchids are fertilized by Insects;" the " Move- 

 ments and Habits of Climbing Plants ;" the " Variation of Ani- 

 mals and Plants under Domestication;" the " Insectivorous 

 Plants;" the "KfTectsofCrossa.nl Self-fertilization ;" the "Dif- 

 ferent forms of Flowers on Plants of the same Species;" the " Power 

 of Movements in Plants;" certainly the field was well mapped 

 out. Everv book as it appeared gave a new impetus tobioiogical 

 botany, and at once directed attention to what in many cases had 

 been almost entirely neglected subjects. It is, however, not so 

 much what Mr. Darwin saw that others had not seen, for his
