Shrubby CExothera. Vulgo — Sun-drops. 



Root perennial 1 Stem 1 to 2 or 3 feet high, often branched from the base, rath- 

 er slender, rigid, terete, mostly purplish, pubescent; pubescence often short, 

 sometimes villose, and almost hirsute. Leaves variable in size, and form, usually 

 about 2 inches long, and 1 third to half an inch wide, often linear-lanceolate, some- 

 times almost rhomboid-ovate, remotely and obscurely denticulate, more or less 

 pubescent and ciliate, sessile. Flowers middle-sized, in a terminal bracteate ra- 

 ceme. Calyx purplish, often nearly smooth, with the tube near an inch long. Pe- 

 tals yellow, sometimes quite pale, broadly obcordate. Ovary clavatc-oblong ; style 

 longer than the stamens, and shorter than the corolla. Capsule about half an inch 

 I »ng, pubescent, or often smoothish, acutely 4-angled, the angles sometimes wing- 

 ed, the sides keeled, tapering at base to a distinct angular pedicel 1 to 4 lines in 

 length. 



ITab. Sterile hills; pastures; woodlands : frequent. Fl. June, July. Fr. Aug. Sept. 



Ohs, This plant is found in very different soils and localities, and seems to pre- 

 sent s-^me perplexing varieties. I think my specimens, generally, rather belong to 

 the (E ambigua of authors, if indeed the latter be a distinct species,— which I doubt. 

 The CE. hybrida, of my Catalogue, although sanctioned by my cxxcUcnt friend, the 

 late Mr. Shweinifz, appears so doubtful, that I am apprehensive it will be safer 

 to rank it among the varieties, for the present. Some sixteen or eighteen addition- 

 al species have been enumerated in the U. States; but it is probable a number of 

 them require a further revision. 



The Gaura biennis, a kindred plant, may probably yet be found in this County; 

 as I have seen it in abundance near Norristown, in the adjoining County of Mont- 

 gomery,
