-f— Corolla veiy villous in the throat, very short: root apparently perennial. 



S. glabra, Michx. Spreading or decumbent, smooth and glabrous : stems a foot or so long : 

 leaves oblong-lanceolate and oblong (inch or two long), not prominently veined: corolla 

 more campauulate than funuelforni, little surpassing the large calyx-teeth (only a line and a 

 half long) : subsessile anthers and style included : fruit somewliat turbinate, smooth (nearly 

 2 lines long), crowned by the 4 conspicuous at length triangular-lanceolate spreading calyx- 

 teeth, their bases slightly united. — Fl. i. 82 ; Pursh, Fl. i. 105 (excl. the remark that corolla

S. tenuior, L. partly, Lam. Ascending or spreading : leaves oval-oblong to oblong-lance- 

 olate, more or less scabrous, with 4 or 5 pairs of more prominent veins : corolla funnelform, 

 twice or thrice the length of the calyx, and with more or less exserted stamens' and style, 

 yet in some plants nearh^ as short as in the preceding species, and with stamens and style 

 included (probably dimorphous) : fruit didymous-obovate, commonly pubescent or puberu- 

 lent (only a line or so long), coriaceo-crustaceous, crowned with the four short deltoid 

 or triangular-lanceolate distinct calyx-teeth. — L. Spec. i. 102, as to Pluk. Aim. t. 136, f. 4,

 blackish, with inconspicuous venation : glomerules mostly small and few-flowered : corolla 

 only half-line long, short-campanulate, glabrous inside : subsessile anthers and style included : 

 fruit globular (a line or less long), very smooth or rarely obscurely puberulent, thinnish,

S. parviflora. Annual, glabrous or a little hirtellous-pubesceut : stems slender, spreading 

 or erect, a span to a foot higli : leaves from narrowly lanceolate to spatulate-oblong (inch or 

 less long), obscurely veined : glomerules in many of the axils, globose : corolla salverform,

 smooth or sometimes obscurely hirtello-puherulent : stipular bristles few : leaves numerous, 

 about the length of the iuternodes and usually axillary-fascicled, narrowly linear (inch or 

 less long), seldom over a line wide, veinless, not rarely with revolute margins, 2 to 6 upper-
