both forms of D. alpina and D. Fladnizensis with predomi- 

 nant ciliating of the leaves. I have seen original specimens 

 of D.pilosa Adams, they seem to belong to D. Fladnizensis. 



Draba ochroleuca Bunge is a form of D. alpina with 

 pale coloured flowers. Synonyms are D. gelida Turcz. and 

 D.primuloides Turcz. I have seen original specimens of them all. 



Draba corymbosa R. Br. is for the first time mentioned 

 by Robert Brown in Ross's voyage as a new species, but 

 with a?, and without description; only it is mentioned, that 

 the plant comes near to D. oblongata and D. rupestris. Th. 

 Fries has informed us (Botaniska Notiser 1873) that in the 

 British Museum, where the Herbarium of Rob. Brown is 

 incorporated, under the name of Draba corymbosa from the 

 hand of the author only occurs a Cochlearia; and I have 

 myself seen , that this is the case. J. Vahl has under this 

 name combined both forms of Draba alpina (D. oblongata) 

 and Draba hirta (a dwarf form of D. hirta v. rupestris 

 (R. Br.) see Fig. 16 a) as specimens in the Arctic herbarium 

 at Copenhagen from Spitzbergen show us. Draba corymbosa 

 from Greenland determined by Lange and figured in Flora 

 Danica tab. 2418 are various forms of D. hirta. Watson has 

 quoted Draba corymbosa as a variety of D. Fladnizensis, 

 but cites Fl. Dan. tab. 2418 and Lange Conspectus Fl. Groenl. 

 for this, and adds: „Greenland and perhaps also (the original 

 specimens) from the western coast of Baffins Bay. Many of 

 the specimens from Greenland and Spitzbergen, that have 

 been referred to it, appear to belong some to D. alpina and 

 others to D. hirta". Perhaps it is best now to leave off 

 speculating on, what Draba corymbosa may have been, and 

 in future to leave it out of consideration. 



Draba Martinsiana J.Gay, by the author himself after- 

 wards named D. Fladnizensis v. exscapa , is according to 

 original specimens, which I have seen, more probably Draba 

 alpina. Th. Fries had first (in Öfversigt Vetensk. Akad. 1869)
