"Much the same may be said of this as of Coulter's Botany of Western Texas. 

 Rydberg's Flora, however, is more useful in the northern part of New Mexico than 

 Coulter's in the southern part, being newer and more complete. The relation between 

 the flora of northern New Mexico and that of southern Colorado, too, is possibly closer 

 than that existing between those of southern New Mexico and western Texas. Almost 

 all the plants occurring in the Santa Fe and Las Vegas mountains and the surrounding 

 region will be found listed in the Flora of Colorado.
