Arundinaria maorosperma Michx. Cane Reed. Abund- 
ant in a few localities. Dense cane brakes occur at remote 
intervals in the bottom lands of the Sabine and Neches 
rivers and a few of their smaller tributaries. 
Alnus rugosa (Du Roi) K. Koch. Alder. Very com- 
mon in swamps, forming dense thickets. 
In probably few regions are the types of vegetation more 
sharply contrasted than in the Texan forests, a slight 
account of which I have here attempted to give. The 
ecology of this region merits a more thorough study than 
it was, in the nature of things, possible to’ give it in con- 
nection with the forestry survey. Such a study may, it is 
hoped, prove possible at some future time.
