À southern type. 
Flowers and fruits abundantly. 
Hibernates undoubtedly covered by snow. 
A 182. Sedum villosum L. 
On warm, not too dry rocky slopes, favourably exposed to the sun. 
Disko: From several places near Godhavn (several coll.) Diskofjord: Kua- 
nerssuit 69°35’ (P.); no doubt often overlooked on the south-land. 
Mainland: Rather common in the domain of Holsteinsborg and the inner 
parts of the land north hereof to Sydostbugten. North of the ice-fjord of Jakobs- 
havn known from Jakobshavn 69°13’ and Päkitsoq 69°30’ (V.; P.). 
A southern type, north of the area only once found at Qarajaq 
70°30. (Vh.). 3 
Abundantly flowering and fruiting; besides abundantly vegeta- 
tive propagation. | 
Hibernates under a thick cover of snow and often of spring-ice. 
XXIV. Saxifragaceae. 
| 183. Saxifrasa oppostifolia L. 
On highland-moraines down to the shore, occurring аз well in 
barren places: gravel and open clayey flats, as among other plants when 
not overshaded by these. Thus it often grows among grasses, and in 
this case it flowers before the grass begins to sprout. 
Very common throughout the whole area. 
Widely ranging in Greenland without southern or northern limit; 
in the southern part, however, less prominent and usually alpine. 
Flowers and fructificates abundantly. 
Often snowless during winter. 
Not much variable. The formes pulvinata and reptans described 
by ANDERSSON and HEssELMANN (Bih. К. 5. Vet. Ak. Handl. В. 26, 
Aid. III, Nr. 1, 1900, р. 25, fig. 10—12) are very common. The last, 
as remarked by the authors, usually in places inundated during the 
spring-time. Also very commonly found on gravelly banks of brooks. 
A 184. Saxifraga Aizoon (L.) Jaca. 
On sunny rocks and slopes, open spots in the heath and among 
grasses. 
Disko: Rather common on the south-land and in the fjords, not observed on 
the north- and Waygat coast (Р.). 
Mainland: From the inner gneiss-domain north of Torssukåtak and down 
to the Jakobshavn icefjord in several places, though not common. South of the ice-
