are chiefly confined to the vicinity of streams, Uke the trees in the 

 prairies. The only common shrulis seem to be CaUicarpa Ameri- 

 cana and Myrica ccrifera. The herbaceous flora was difficult to 

 identify from a moving train, but it seems decidedly poorer in 

 species than that of the southeastern pine-barrens, and not many 

 plants were in bloom in August. The most abundant herb is a 

 coarse grass, presumably an Andropogon, and the most conspicti- 

 ous were two species of Lacinlaria, which I have guessed to be 

 L. pycnostachya and L. acidota. (A httle later I had opportu- 

 nity to examine the pine-barrens more closely in eastern Texas, 

 and the results are published in the Bulletin for July, 1920.* 



The Hammock Forests 

 Within a few miles of the Sabine River the country is low and 

 clayey and probably occasionally inundated, though the soil would 

 hardly be classed as alluvial. These conditions are unsuited to 

 long-leaf pine, and the forests are comparatively dense and 

 hammock-like, with approximately the following composition : 



Trees 

 Finns Taeda Quercus Phellos 



Liquid anihar Sfyraciflua Quercus falcata 



Nyssa uniflora Quercus stellata 



Quercus Michauxii Quercus Marylandica 



Taxodium distichum Hicoria aquatica ( ?) 



Shrubs 

 Cephalanthus occidentalis Aralia spinosa 



Herbs 



Tillandsia usneoidcs 

 Most of these are the same species already noted as growing 

 along streams in the pine-barrens, and this might be regarded as 

 merely one of the strips of bottom-land timber, but for the fact 

 that it is considerably wider on the Texas side, where it deserves 

 to rank as a distinct region.
