278 EARLY ICELANDIC BOTANY. 



nivalis, O. tenella, Jniicns highimis, J. triglnm.is, Snxifrar/n punctata, 

 S. Cotyledon, Stelluria bijiora, S. cerastoides, Saxifroga rividnris, Ste.l- 

 laria hnmifusa, Arenaria clliala, RaHiniciilns liijperhorens, Diapeusia 

 lapponica, Epilohiiim corijmbosiim, Papaver radicatiun. There are also 

 figures of the following, drawn from Greenland specimens : — Andro- 

 meda CfenUea, A. tetraquetra. Campanula unifiora, Saxifraga tricuspi- 

 data (here first described, figured, and named), Potentilla nivea. The 

 figures are uncoloured but fairly characteristic drawings. 



As some of the Icelandic species above named are plants about 

 which Professor Babingtou has doubts of difierent kinds, it will be 

 well to see what light can be obtained from Rottbdll's descriptions and 

 plates. Some information about them has also been obtained from 

 Gunner's 'Flora Norvegica,' pars posterior, published in 1772, in 

 which Eottboll's paper is frequently quoted, but where his names are in 

 several cases not adopted, e.g. Ranunculus hyperhoreus, K,ottb., is named 

 R. Ammamii, and Gentiana tenella, Rottb., R. Kceningii. Gunner appears 

 to be generally accurate, but is quite at fault at p. 140, where he gives 

 a Scandinavian locality for Swertia (Pleurogyne) rotata, — a plant he 

 evidently quite misunderstood,* and the figure of which in Fl. Dan. 

 t. 348, he names Gentiann islandica. He also quotes Fl. Dan. 3+4 

 ((?. involucrata, Kottb.) twice over, once as G. auren, L. (p. 54), and 

 then as G. quinquefoUa, L. 



Ranunculus hyperhoreus, Rottb., here first named, and fully de- 

 scribed (p. 458). Figured (f. 1(3)- but the plant had been previously 

 engraved in Fl. Dan. tab. 331. 



Papaver radicaturn, 'Roith. This is, no doubt, " P. radiatum" of 

 Babington's 'Revision* (p. 293). It is described on p. 455, and 

 figured in f. 24. As Professor Babington states, it does not seem to 

 be more than a small variety of P. nudlcaule. 



Arenaria ciliata, L. Babington excludes this, but it is figured from 

 Konig's specimens in Fl. Dan. t. 346, and Eottboll's figure (f. 15) 

 represents this species rather than A. norvegica ; his description (p. 

 448) also agrees Avith the former. 



Stellarla humifusa, Rottb. This is also excluded by Babington. 

 There can, however, be no doubt about its occurrence. The species 

 was founded on Icelandic specimens, and is fully described by llottboU 

 on p. 447, and figured in f. 14. 



* Hartman (Skand. Flora, ed. 9 (1864) p. 276) says that, according to Prof. 

 Blytt, Gentiana tenella was the plant intended by Gunner.
