 cotton is more ;>rofitably cultivated and sickness more 

 general. — Its cen.ral, black, elastic and curled fibres,

The venerable W, Bartram informs me of the existence 

 of a Bromeiiseform species of Tillaiidsia, nea.v the moutk

This interestmg- and sing-ular genus, consisting- of 26 

 species, is, with the above exceptions, exclusively indige-

 tation. 



303. TRADESCANTIA. Z. (Spider-wort.) 

 Calix 3 -leaved Petals 3. Filaments villous. 

 Capsule 3-celled, few- seeded. 



Habit similar to CommeUna, differing, however, in the 

 disposition of the flowers which are pruduced in unequal 

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

 lucrum, and in the filaments which are bearded. 



Species. 1, T. virgiiiica. Throughout the Atlantic 

 states, and westward into Upper Louisiana. 2. rosea. 



This genus is almost exclusively indigenous to India 

 and tropical .\merica, tiiei-e being, besides the above, but

504. DIPHYLLEIA. Mkhaux. 



Calix 3-leaved, deciduous. Petals 6, opposite 

 the calix. Anthers growing to the filaments, 

 cells opening from the base to the summit by so 

 many vertical elastic valves. Berrij 1-ceIicd. 

 Seeds 2 or 3, roundish. 



Stem 2-1eaved; leaves excentrically peltate, palmately 

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