3. S. afSnis Welw. ms. in Herb.

 8 to 12 in. high, branched from the base ; radical leaves- 

 rostilate, broadly elliptical, obtuse ; stem quadrangular, with 

 the angles sub-acute and membranous-winged, several times 

 dichotomously divided, gradually finishing in a corymbose flower- 

 ing panicle ; stem-leaves ovate or lanceolate, acute or acuminate- 

 at the apex, somewhat narrowed at the base, sessile, the upper-

 between the corolla -lobes ; anthers attached at the middle of the

This difilers from S. Irachyphylla by the stem-leaves being ovate- 

 acuminate and not obtuse, by the much laxer inflorescence, by the- 

 alate calyx, by the corolla-lobes being gradually more acuminate, and 

 by the larger glands on the anthers.

 branches opposite ; flowers yellow, rather small, with a circle of small 

 glands between the bottom of the calyx and the funnel-shaped corolla; 

 corolla-lobes ovate, rather obtuse ; stamens included ; ovary very 

 shortly stipitate, beset around the base with very small crowded 

 glands sessile at the bottom of the calyx, that is, at the base of the 

 corolla ; style sparingly pubescent, reaching the middle of the anthers ;
