On the Red River, Nuttall ! Rocky hills in the prairies near Fort Tow- 

 son, Arkansas, Dr. Leavenirorlh !—U Stem 14-2 feel hiifh, somewhat 

 branched. Leaves about 2 inches long ; and li inch wide ; petiole shorter

Sandy fields and road-sides, New-Jersey ! to Florida ! and Avest to Arkan- 

 sas! Jiily-Aug.— (p Stem 12-18 inches high, branching from near the 

 base. Leaves 1-li inch long, obtuse or cordate at the base : petiole 6-8 lines 

 long. Peduncles nearly solitary, but often appearing clustered from the short 

 axillary flowering branches. Calyx hemispherical. 5-angled ; segments broad- 

 ly ovate, acuminate. Petals obovate, yellow. Carpels easily separating 

 when ripe, strongly reticulated on the sides. Seeds dark purplish-brown, 

 glabrous. 



2. S. fasciculata: stems somewhat hairy ; leaves linear, denticulate-ser-

 flowers sessile, terminal ; carpels 5-7, scarcely rostrate, strongly reticulated

Texas, Drummond! — 2^ ? Stems about a span high, branching from the 

 base. Leaves f of an inch long and a line wide, mostly with a few serratures 

 towards the apex, nearly glabrous above, strllately hirsute beneath : petiole 

 about \ the length of the lamina. Calyx hemispherical; segments ovate, 

 acute. Corolla not seen. Carpels short and broad, strongly roughened with 

 projecting points. — This species greatly resembles a Sida figured in St. Hi- 

 laire's Fl. Bras.
