or quite smooth. Pet. almost linear, pale yellow, obtuse, slightly 

 cloven, triple-ribbed, rather longer than the calyx. 

 This species has never till now been rightly understood. I received 

 it for thS"true ccpspitosa, which latter was not known to Mr. Hud- 

 son. Mr. D. Don's remarks have led me to reconsider the sub- 

 ject, and to correct what is before the publick in the Fl. Brit. 

 and Rees's Cydopadia , respecting this plant and some of its 

 allies.

Herb more densely tufted than the last. Leaves crowded, lanceo- 

 late, fleshy, deep green, smooth, shining, obtuse and abrupt. 

 Stems erect, slender, slightly leafy, 2 or 3 inches high, corym- 

 bose, bearing 3 or 4 small Jlowers, on downy viscid stalks. Cat, 

 covered in like manner with short, viscid, glandular hairs ; its 

 segments broadly ovate, obtuse, 3-ribbed. Pet. obovate, or 

 nearly oval, a little longer than the calyx, greenish yellow, with 

 3 reddish ribs, united for a small distance above the base. 



The description in Engl. Bot. was made with some reference to 

 S. tenera of Suter, Don Tr. of L. Soc. v. 13. 410, for which I 

 had mistaken this plant, and to which the synonyms I originally 

 quoted belong. Almost every botanist, till very lately, has con- 

 founded these species. Whether the leaves of S. pygmcea are 

 ever divided, or whether ^S. grcenlandica may sometimes have 

 been confounded with it, I am by no means certain. I cannot 

 but give the plant a place here, on the positive authority of my 

 late friend Mr. James Donn, Curator of the Cambridge garden^ 

 though others deny its having ever been found in Scotland.
