The Flora of Disko Island and Adjacent Coast of West Greenland. 133 
| 230. Phyllodoce coerulea (L.) Bas. Bryanthus taxifolius Gray). 
In herb-mats and luxuriant sheltered heath. 
Disko: Common on the south coast and in Diskofjord as well as on the 
northern shore of Mellemfjord. Also occurring north of Nordfjord, but searce. Not 
observed on the Waygat-coast, nor in the big valleys leading to the heads of the 
northernmost fjords (P.). 
Mainland: Rather scarce and restricted to favourable spots in the northern 
parts, becoming commoner southwards and at greater distance from the shore (P.). 
Widely distributed in West Greenland, without southern limit; 
the northern limit somewhere north of 74°. 
In the area mostly a lowland plant. 
Abundantly flowering and fructificating. 
Covered by thick layers of snow, often occurring on spots with long 
lasting snow-patches. 
XXXIV. Ericaceae. 
Vv 231. Cassiope tetragona (L.) Don. 
In heath and not too wet bogs. Also in fell-fields up to the borders 
of the snow fields. 
Very common throughout the whole area. 
Widely distributed in West Greenland without northern limit. 
The southern limit is about 64° where the plant only occurs in alpine 
inland stations. Already in the fjords between 66°—67° scarcer on the 
sunny slopes than on the northern; observed, however, locally down 
to the shore. A northern type. 
Flowers and fructificates abundantly, the fruits ripen under the 
snow; and the seeds are not dispersed till the following spring. 
This heather attains its most vigorous growth on sunny, well drained 
spots with abundant watering during the vegetative season. Next to 
Empetrum the most characterizing shrub in the heath. Like this it is 
collected in large quantities for fuel. Owing to its highly resinous con- 
tents it will burn in flames, even in a wet state. 
Normally covered by thick layers of snow, in the highlands some- 
times also snowless. 
ji 232. Harrimanella hypnoides (L.) Covitie. Proe. Wash. Ac. 
Se. II. 1901. p. 575 (Cassiope hypnoides (L.) Don.). 
On spots with long lasting snow, nearly always together with 
Salix herbacea. 
Common throughout the whole area. In the big fjords of the south- 
ern part, however, rather scarce in the lowland, commoner on elevated 
stations or on the northern slopes.
