A tree 40 — 50 feet high, with smooth bark and branches thinly dispersed. 

 Leaves alternate^ nearly circular; with large irregular teeth, and prominent 

 veins, when young tomentose, becoming glabrous with age, on petioles 2^ — 4 

 inches long* Flowers in small axillary cylindrical aments, shooting out 

 early in the spring with the first buds, very small and inconspicuous. Cap' 

 stiles small, containing many minute seeds surrounded by long cottonlike 

 hairs which causing them to float readily on the air, render them easy of dis- 

 persion, and have given to several species in different parts of the United 

 States the common name of Cotton-trees. 



Grows in the mountainous districts of Carolina and Georgia. 



Flowers March.

A large tree, growhig 50 — 80 feet in height and 2 — 3 in diameter; the 

 young branches are all winged ahd angled by the decurrent petioles or by 

 the junction of different branches, and these vestiges are not effaced for seve- 

 ral years. Leaves ovate-deltoid, acuminate, serrate, glabrous, sometimes 

 slightly cordate, on the young shoots 5 — 7 inches long, 4 — 5 wide, on the 

 old trees smaller, on compressed petioles 2. — 4 inches long. Flowers very 

 small. Seed not as conspicuously villous and white as in some other spe- 



cies. 



This is, I believe, the only species of tins genus which is found along the 

 sea-coast of Carolina and Georfria. Its leaves are easilv a[rit;Uod b3' the 

 ^ind. Its wood is light, brittle, and not durable. 



Grows along the margin of river?. 



Flowers March.
