The Editorial Committee of Standardized Plant Names recom- 

 mends that there be "one standard common name for each plant." 

 In reference to the names of species and true varieties the term 

 "plant" really refers to a group of individuals of successive seed 

 grown generations. When two or more common names are in use 

 for a group of plants only one is approved. Numerous new com- 

 mon names have been improvised. Numerous double names and hy- 

 phenated names in common use have been reduced to a single word ; 

 as, Lilyofthevalley, Jerusalemartichoke, etc. 



There is much information concerning plants available in 

 Standardized Plant Names. For any genus of plants one may learn 

 how many species, varieties, polybrids, and clones are listed as im- 

 portant to man. In numerous genera the horticultural clones are 

 segregated and listed by common names and the names of the 

 originators are given (see Aster, Begonia, Azalea, Hemerocallis, 

 etc.). There is a list of plant patents with an index of the plants in- 

 volved. Lists are given of poisonous plants, range plants, state 

 flowers and trees, fiber plants, herb garden plants, and other groups 

 of plants that have special interest. These lists are useful as a basis 

 for obtaining specific information in descriptive literature. 



In the designation of species, of clones, and of polybrids in 

 Standardized Plant Names there are numerous inaccuracies. Es- 

 pecially are many definitely recognized clones listed as polybrids or 

 even as species ; but in most cases this treatment follows that of 

 some manual. This condition is illustrated in the nomenclature sug- 

 gested for the genus Po pubis. At this time this reviewer wishes to 

 record that the statement made in Standardized Plant Names that 

 he collaborated in deciding the nomenclature presented for the 

 genus Populus is an error. 



Criticism of the volume is to some degree tempered when one 

 reads the following statements in the preface: "Standardized Plant 

 Names adopts the rule that species and natural varieties only are 

 entitled to Latin or botanical names and that all hybrids, clones, 

 polybrids, horticultural varieties and the like should receive suitable 



English or common names Time and other serious handicaps 



make it impossible for the Editors to consistently carry out these 

 principles. Yet reasonable progress has been made and it is hoped
