The Flora of Disko Island and Adjacent Coast of West Greenland. 107 
4 210. Callitriche autumnalis L. 
Disko: The north-west coast at ca. 70710” (P.); at the mouth of Nordfjord 
69°55’ (P.); in pools in Blæsedalen at Godhavn 69°17’ (E. P.; Th. P.). 
Mainland: Sermermiut at Jakobshavn 69°13’ (P.); archipelago of Egedes- 
minde: in some places in the Nivaq-Bugt 68°35’ (Kr.). 
Only found in the mentioned places in Greenland. The specimens 
from the two northmost places are very small; the leaf-bearing sprouts 
only 15—35 mm long with 8—14 pairs of leaves. The leaves 5—10 mm 
long, 0,4--0,8 mm broad. But the specimens from Blæsedalen sometimes 
become 20 cm long in favourable summers. 
Also in Greenland a perennial. 
XXVIII. Empetraceae. 
| 211. Empetrum nigrum Г. 
In heath, moss-bogs, sometimes at the edges of willow-copses. 
Very common throughout the whole area. 
Widely distributed in Greenland, without southern limit and 
perhaps also without northern limit. 
From the coast ascending to considerable altitudes, but not as far 
as, for instance, Cassiope tetragona, and never as а pioneer on fresh 
morainic soil. 
Abundantly flowering and fruiting. 
Normally covered by snow during winter. 
Empetrum ıs the most important heath-species for the natives, 
who use it for fuel; the berries are commonly gathered and eaten. 
ХХУШ. Onagraceae. 
A 212. Epilobium anasallidifolium (L.) Lam. 
In open spots in moist heath, moist places in fell-fields, often on 
iresh moraines, along water-courses; sometimes in herb-mats. 
No doubt often overlooked because of ıts diminutiveness. 
Disko: On the south-land and the valleys here, Diskofjord and Mellemfjord 
known from .many places; undoubtedly rather common. In valleys from the head 
of Nordfjord, common; the north-west coast, rather common far from the coast (P.). 
Mainland: Paotüt 70°12’ (Htz.); southwards not observed till N. Isortoq 
67°15’ (Ros.) and Holsteinsborg 66°55’ (W. & H.); no doubt overlooked. 
A southern type; north of the area found a few times up to 
72°8’ (P.). Also overlooked south of the area; it seems to prefer the 
coast-region, not being able in competition to hold its own.
