VEGETATION OF BRAZOS CANYON 191 



wootonii, Verbena bracteosa, Munroa squarrosa, Castilleja linariae- 

 folia, Madia glomerata, Marilaunidium angustifolium, Stachys 

 scopulorum, Lactuca pulchella, Rumex mexicanus, and Lathy rus 

 decaphyllus. 



The vegetation of the Brazos Canyon region thus illustrates 

 two of the most characteristic life zones of New Mexico, the 

 Canadian and Transition, the second of which shows two well 

 differentiated subdivisions. It is typical of many of the moun- 

 tain areas of New Mexico, although the writer is not prepared 

 to state that the same divisions of the Transition can be made 

 everywhere. Although scenically the region is equalled by'few 

 in the State, floristically it is surpassed in interest by many 

 other areas, for in number of species the flora appears to be 

 much inferior, for example, to that of the Santa Fe and Las 

 Vegas ranges, and there is found none of that Mexican element 

 which makes the White and Mogollon Mountains so interesting 

 botanically.
