Root annual. Stem 2 to G inches high) dichotomoasly or sometimes brachiately 

 branched, rarely simple, 4-angled, smooth, angles slightly winded. Leaves about 

 half an inch long, and an eighth to a quarter of an inch wide, ovate-oblong or ovatt- 

 lanceoiate, rather acute, closely sessile. Plotters axillary, solitary, or termina. 

 ting the branches in pairs, generally one in the forks of the stem or branches, on 

 angular peduncles an eighth to near half an inch in length. Calyx (tangled, fl. 

 parted ; segments subulate, erect, closely appressed and even slightly adhering to 

 the tube of the corolla, at first nearly as long as the tube, finally little mure than 

 half as long. Corolla with the limb bright purple, 5 parted, (occasionally 4- partes 

 and tetrandrous), lobes lance-ovate, mostly erect, or conniving; tabe yellowish 

 green, near half an inch long, contracted between the throat and ovary, somewhat 

 ventricoso thin and membranaceous below, adhering to the ovary, and shrivelling. 

 Anthers a little twisted after flowering. Style bifid at apex ; stigmas compressed, 

 suborbicular. Capsule 1-celled, 2-valved ; valves opening at summit and recurr- 

 ing. Seeds numerous, small, rugose punctate. 



Hub. Great Valley, near Brooke's Mill : very rare. Fl. July-Sept. Fr. Aug-Oct. 

 Obs. I do not find this handsome little plant noticed by any American Botanist, 

 except Muhlenberg ;— though Dr. Pickering informs me it is the one intended by 

 Dr. Bec^ under the name of E. Centauriu^i, found in New York. Dr. P. has 

 fcund it, himself, on the Eastern Shore of Virginia. Our plant was first detected 

 in July, 1835, by Mr. William Hartmax, a zealous and promising young Botan- 

 ist, of this County. It appears as if it might be indigenous in the above locality ; 

 and yet one would suppose if it were so, it would be more extensively distributed. 

 It is the only species in the U. States,— unless Dr. Beck's E. Centaur ium be di» 

 tincu Lestiboiulois, however, in his Botanograpliie Belgique, expressesthe opi* 

 ion that the E.pulchella is only a variety of E. Centaurium.
