DESCRIPTIONS OF NEW PLANTS PRELIMINARY TO A 
REPORT UPON THE FLORA OF NEW MEXICO. 
By E. O. Wooton and PavL C. STANDLEY. 
INTRODUCTION. 
For several years the writers have had in preparation a flora of 
New Mexico. The manuscript of the grasses was the first part to be 
completed, the material of this family in the herbarium of the New 
Mexico Agricultural College having been carefully worked over in 
the winter of 1906-7. There has been published recently as a bulletin 
of the New Mexico Agricultural Experiment Station a list of the 
grasses and grass-like plants of the State in which are enumerated 
all the species of the Poaceae, Juncaceae, and Cyperaceae, which we 
have seen from within our limits, the paper being accompanied by 
keys to the genera and species. While the material in the Agricul- 
tural College Herbarium was the basis of that report, all of that in 
the National Herbarium has now been gone over carefully, resulting 
in many additions to our first list. 
The Cactaceae of the State have been treated in a similar bulletin 
published by the same institution. The flora of New Mexico is par- 
ticularly rich in representatives of this family, no less than 67 being 
known to occur within the State, while additional ones are doubtless 
to be discovered. 
Other briefer papers dealing with special groups of New Mexican 
plants have been published from time to time, notably one treating 
the genus Androsace,’ one upon the genus Delphinium,’ and several 
describing miscellaneous new species from the State.’
