BOTANY.— Flora of New Mexico. E. 0. Wooton and Paul C. 

 Standley. Contributions from the U. S. National Herbarium, 

 Vol. 19. Pp. 1-794. 1915. 



This volume consists of a systematic account of the phanerogams 

 and vascular cryptogams native and advent ive in New Mexico. There 

 are provided keys to the orders, families, genera, and species, and brief 

 diagnostic descriptions of the genera are given. Under each species 

 are included the place of publication of the specific name, the principal 

 synonyms, type locality, general range, and distribution in New Mexico, 

 and any notes of particular interest concerning the peculiarities of the 

 plant. Definite collections are cited in the case of some of the rare 

 species. 



There are listed for the state 2903 species, distributed among 848 

 genera. Of these 42 species are pteridophytes and 25 gymosperms. 

 The largest family is naturally the Asteraceae, including 511 species. 

 The other large groups are the grasses (270 species), Brassicaceae 

 (101), Fabaceae (189), and Scrophulariaceae (100). The Cactaceae are 

 represented by no less than 67 species. The largest genus is Astragalus, 

 with 54 species; but some of the others are notable, for example, Carex 

 (41 species), Quercus (24), Eriogonum (40), Opuntia (32), Gilia (20), 

 Pentstemon (35), Castilleja (20), Erigeron (46), Artemisia (23), and 

 Senecio (41). 



The work includes also a geographic index of all the localities in the 

 state at which plants are known to have been collected, and the altitude 

 for each is given when it could be definitely ascertained. P. C. S.
