to be at Camden in South Carolina, from which point 

 Cotton is more profitably cultivated and sickness more 

 general. — Us central, black, elastic and curled fibres, 

 which remain after maceration, are not much unlike horse 

 hair, and are used for similar purposes, such as stuffing 

 mattrasses, &c. 



The venerable W. Bartram informs me of the existence 

 of a Hromelireform species of Tillamlda, near the mouth, 

 of the Altamaha. Tliis is probably T. polustachia of Aluh-' 

 lenberg-'s Catalo.cf'ue. 



This interestin.if and sing-ular genus, consisting of 2^ 

 species, is, with t!ie above exceptions, exclusively indige- 

 nous t ) tropicul America, forminpr w'ith many other para- 

 sit'C planisone of the most singular features of its vege- 

 tation.

 Calix 3 -leaved Petals 3. FlUnneuts villous. 



Capsule 3-celIed, fcw-sccded. 



Habit similar to Comiueliiia, differing, however, in the 

 disposition of tl^.e flowers wliich arc produced in unequal 

 terminal umbells, subtended by a long, 2 or3-leaved invo- 

 lucrum, and in tlie filaments which sue hcui-ded. 



Species. 1. 'J', virg-inica. Tlu-oughout the Atlantic 

 Stales, and westward into Upper I ouiiiana. 2. rosea. 



This genus is almost, exclusively indigenous to India 

 and tropical America, tiiere being, besides the above, but 

 a single species hitherto discovevcd in tlie rest of tiie 

 worltl, viz. at tlie Cape of Good H(3pe (xA.frica.) 



304. DIPHYLLEIA. .Michanx. 



Calix 3-lcavrd deciduous. Petals 6, opposite 

 tlie calix. Anthers .^rowiiii^ to tlie filaments, 

 cells openiriji^ from the base to the summit by so 

 many veitical elastic: valves. Bcrrij 1 -celled. 

 Seeds 2 or 3, roundisli. 



Stem 2-Ieaved; leaves excentricnlly peltate, palmately 

 lobed and semibifid; flowers in a terminal, solitarv, um- 

 bellate cyme. (Petals obsolete 3-nerved. Valves "of the 

 anthers conspicuous, spreading horizontally, persistent; 

 germ ovate, exceiuric, 2 to 4-seeded; style none; stigma
