PREFACE 



The accompanying papers are designed to assist students of the 

 taxonomy and distribution, and to some extent of the ecology, of the 

 New Mexican flora. The first contains an annotated list of all those 

 plants that have their type localities in New Mexico. So far as can 

 be learned no list of this kind has ever been prepared before for any 

 State or Territory, in spite of the obvious advantages which such a 

 work offers. It is interesting to learn that from New Mexico alone 

 almost seven hundred new plants have been described. Accompanying 

 the list of species is a list of localities with the names of the species 

 described from each; and in order to facilitate the finding of the 

 localities, a map of New Mexico has been prepared upon which all 

 the type stations have been conspicuously marked. As an aid in 

 the study of the collections made by some of the earlier botanical 

 explorers of this region notes regarding their itineraries have been 

 collected and tabulated. It has been found necessary in preparing 

 the list of species to form several new binomials; these will be found 

 listed at the end of the paper. The bibliography which forms the 

 second of the papers is intended to be a complete index to the litera- 

 ture of New Mexican botany.
