Communicated with some other very interesting plants 

 from the Andes of South America, by Wm. Jamieson, Esq. 

 Professor of Botany in the University of Quito. It is pro- 

 bably the largest species of Draba which exists, and forms a 

 striking contrast with the Draha verna of our walls and 

 hedge-banks, or the D. hirta of our mountains. It seems to 

 agree with Humboldt and Kunth's D. alyssoides in almost 

 every particular, except that the leaves are not generally 

 erect, and the siliculc^ are too much inclined to lanceolate to 

 be called simply ovate. But if this be the same plant, we do 

 not see why those authors should doubt it being a real Draba.
