In pastures and heathy ground^ on a barren gravelly soil. 



Annual. May. 



Root small, fibrous. Whole herb glaucous and \try smooth. 

 Stems several, erect, 3 or 4 inches high, round, leafy. Leaves 

 opposite, sessile, linear-lanceolate, entire, single-ribbed. Flowers 

 erect, solitary, on long terminal stalks, conspicuous for the shining 

 white of their petals and the edges of their calyx-leaves. Caps. 

 of a light shining brown. 



An elegant little plant, certainly misplaced in Sagina, as its habit 

 and the structure of the capsule evince. The uncertainty of 

 its genus is hinted, in FL Brit, and Engl. Bot. ; though I had not 

 then seen Ehrhart's work, to consider his characters. The ori- 

 ginal specific name erecta ought not to be changed. We may be 

 thankful to get rid of Quaternella.

Cal. in 3 or 4? deep, spreading, large, ovate, succulent seg- 

 ments, inferior. Pet. 3 or 4, ovate or lanceolate, acute,

 with its divisions. Nect. none. Filam. 3 or 4, simple, 

 awl-shaped, shorter than the corolla, erect. Anth. roundish, 

 of 2 cells. Germens 3 or 4, ovate, superior. Styles ter- 

 minal, very short. Stigmas obtuse. Caps. 3 or 4, oblong, 

 pointed, recurved, bursting lengthwise at their upper edge, 

 each of 1 cell, and 2 valves. Seeds ovate, 2 in each cap- 

 sule. 



Small, succulent, annual herbs, with numerous branches, op- 

 posite sessile leaves, and generally axillary^otLT?-^. This 

 genus differs from Crassida in the want ol nectariferous 

 scales, as well as in number of the several parts.
