3. — Remarks on the Flora of East- Arctic Greenland 



(BUCHENAU).— Pp. 20-21. 



The vegetation of East- Arctic Greenland agrees in all important 

 points with the well-known flora of West Greenland. On the 

 south coast of East Greenland, Kemisak Island, 63° 37' N. Lat., 

 examined by Graah, is the most northern spot whose vegetation 

 is thoroughly known. Between Kemisak and Kaiser-Franz- Joseph 

 Fjord lie nearly nine degrees of unsearched territory. Scoresby 

 landed at only one intervening point; but even reckoning the 

 Sound named after him as part of the known northerly range of 

 coast, there remains a gap of seven degrees between the extreme 

 points waiting for exploration. We see, therefoi-e, why the flora 

 of the southern part, and that of the northern part of East Green- 

 land difler so greatly. Whether within that great space of the 

 nine, or of the seven degrees, a sudden linrit or a gradual transi- 

 tion between these two botanical regions is to be found, is quite 

 unknown. As far as we know, the south part of East Greenland 

 has no plant but what the west coast possesses. The northern 

 flora of the east coast, on the contrary, is characterised by some 

 peculiarities. The following plants have been found on the 

 northern, but neither on the southern coast of East Greenland nor 

 in West Greenland : — 



1. Ranunculus glacialis, L. 



(very doubtful for West 

 Greenland.) 



2. R. auricomus, L. 



3. Dryas octopetala, L. (forma 



typica !) 



4. Saxifraga hieracifolia, W.K. 



5. S. Hirculus, L. 



6. Pyrola rotundifolia, L., var. 



arenaria, Koch. 



7. Polemonium humile, Willd. 



8. Juncus triglumis, L., var. 



Copelandi, Buchenau. 



9. Deschampsia brevifolia, 



R. Br.
