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 the true caspitosa, which latter was not known to Mr. Hudson. 

 Mr. D. Don's remarks have led me to reconsider the subject, and 

 to correct what is before the publick in the Fl. Brit, and Rees's 

 Cyclopcedia, 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 smaW^otvers, on downy viscid sialks. Cal. 

 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. ij. 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. pygmcca 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.

 fringed ; lowermost undivided. Flowers from one to five,
