slopes, apparently equally luxurious and under equally favourable 
conditions, parallel and close to each other, one of them containing 
Kvans, the other not. 
Archangelica hibernates under thick layers of snow, often, but 
probably not always, with its root in soil that never freezes. On large 
root-specimens the terminal bud is larger than a clenched hand and 
contains a complete inflorescence. A little farther down several smaller 
buds are to be found in the axils of former leaves. Kruuse states |. ¢. p. 
246: »the specimens die after having set fruit«, hence it ought to be 
hapaxanthic. Another common appearance here is: an old root, that 
without any apparent cause, is decayed right down, but hence the axil- 
lary buds are set free, and the plant consequently perennial, being 
also ordinarily indicated as such in the Scandinavian Floras. 
XXXII. Pirolaceae. 
L 222. Pirola minor L. 
In copses and vigorous herb-mats, on Disko usually in shade: not 
in the heath. 
Disko: Rare, perhaps sometimes overlooked; in the vicinity of Godhayn 
69°15’, for instance in Engelskmandens Hayn. (P.); Mellemfjord at Kuanit 69°44° 
(P.); Mudderbugten 69°45’ (Htz.). 
Mainland: Found once at Holsteinsborg 66°55’ (Th. Fr.); Jakobshayn 69°13’ 
(Sor.), in vain searched for here (P.). 
A decided southern type, not common till south of 64° (Ros). 
Only known from the lowland. 
Late flowering, but fructificates at least in warm summers. 
Hibernates abundantly covered by snoy. 
L 223. Pirola secunda L. var. obtusata Turcz (= v. pwmila 
Cu. & Scuu.; var. borealis LANGE). 
In the shade under copses and tall herb vegetation, no doubt often 
overlooked because of its diminutiveness. 
Disko: Near Godhayn 69°15’ in several places and gathered by several col- 
lectors. Brede Dal 69°18’ (Nygaard!). 
Mainland: Prestefjeld near Holsteinsborg 66°55’ (W. & H.: P. & E,). 
A deeided southern type in Greenland, only known from the 
mentioned places. 
This form, known from sub-aretic America and Asia, but not 
from Europe, is rather deviating from the main-species, and as its 
ecological variations in Greenland do not seem to approach the European 
plant, it had probably better be considered an independent species.
