Taxonomically there is nothing remarkable about this list, unless 

 it is that ferns, oaks, Magnoliaceae, Saxifragacege, Sapindaceae and 

 other Polypetalous families are rather numerous, and grasses, sedges, 

 and other monocotyledons, Rosaceae, Leguminosfe, Umbelliferae, Eri- 

 caceae and CompositEe rather few (using all these family names in 

 their older and broader sense). As in the interior hardwood region 

 of the eastern United States, there are more tlowers in spring than at 

 any other season, evergreens are in the miiioritj', especially among the 

 trees, and fleshy fruits are scarce. 



For rare plants this locality compares favorably with the more 

 or less celebrated bluffs on the east side of the Apalachicola River in 

 ]\Iiddle Florida.^" The two places have several species in common, 

 such as Fagus, Juniperii>s, Liriodendron, Liquidamhar, Pinus Taeda, 

 Quercus aiha, Cercis, Ilex opaca, Ostrya, Aesculus Pavia, Bignonia, 

 Aralia spinosa, Hypericum aureum, Adelia ligitistrina, Ptelea, and even 

 Croomia and \Alsine puhera. And the two endemic trees of the Florida 

 bluffs (representing two genera of Taxaceae) are no more remarkable 

 'than the shrubs Croton ^lahamensis and Neviusia, which are not 

 known outside of Alabama. (The former is known from two counties 

 and the latter from three.) It is rather singular that the Croomia, 

 unlike nearly all the other species listed, has its northernmost known 

 limit in the area under discussion. 



Unfortunately civilization is making inroads on these bluffs and 

 ravines, as on many other beauty spots the world over. The smoke
