Korstian (1917: 281) has made use of the herbaceous and shrubby species 

 in distinguishing between Sites I and II for yellow pine in the Datil National 

 Forest in New Mexico. 



"A perusal of the list shows marked differences in the individuality of the 

 vegetation of the two sites. Site I is shown to produce such typical meso- 

 phytes as Mnium sp., Agrostis hiemalis, Bromus polyanthus, Muhlenbergia 

 wrightii, Populus tremuloides, Arenaria confusa, Cerastium longipedunculatum, 

 Silene laciniata, Aquilegia chrysantha, Thalictrum wrightii, Draba helleriana, 

 Potentilla atrorubens, P. crinita, Rosa fendleri, Geranium richardsonii, Viola 

 neomexicana, Amarella scopulorum, Gentiana bigelowii, Prunella vulgaris, 

 Mimulus langsdorfii, Penstemon virgatus, Campanula petiolata, and Solidago 

 neomexicana. Site II bears such transitory species and xerophytes as Poa 

 rupicola, Commelina dianthifolia, Yucca sp., Quercus grisea, Portulaca oleracea, 

 Heterothrix longifolia, Cercocarpus breviflorus and Hymenopappus radiatus.
