THE PLANT WORI.D

usage of most modern manuals, keys to the species, genera and families 

 being placed at the head of each group, while at the beginning of the 

 work there is an elaborate and carefully prepared key to the orders. 

 Measurements are given in the metric system ; and the descriptions are 

 well drawn, though they are in some cases, as for example in Xyris, too 

 concise for easy discrimination. Synonymy is inserted only when the 

 accepted name differs from that used by Chapman or other standard 

 authorities. We are pleased to observe that the author has not con- 

 sidered it necessary to coin book-names for each species, and the only 

 vernacular designations admitted are those in actual use; hence we find 

 no such literary absurdities as "Smith's Contorted Pipewort " to mar 

 the pages of this work. 



It is, however, in the nomenclature and systematic treatment that 

 interest naturally centers, and while we approach the discussion of this 

 phase of the subject with an earnest desire to recognize the justness of 

 Dr. Small's view-point wherever possible, there are several respects in 

 which we can not altogether commend the stand he has taken. 



In discussing the third edition of Chapman's Flora of the Southern 

 States, on its appearance six years ago, the present reviewer remarked : 

 " It is to be deplored that Dr. Chapman did not make some effort to 

 obtain material for examination at least in those genera in which he 

 himself contemplated the establishment of new species. The omission 

 of these well-marked forms is less of an injustice to the botanists who 

 have devoted time and careful study to the plans than it is to the field 

 student who constantly discovers specimens which he can not match with 

 any of those described." Dr. Small can not be credited thus with the 

 sin of omission, for as far as can be judged from a general examination, he 

 has included in his work every species of plant that once grew, is now 

 found, or is ever likely to appear within the limits covered.
