The Flora ol' Disko Island and Adjacent Coast of West Greenland. 133 



i 230. Phyllodoce coerulea (L.) Bab. Bri/anthus 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 scarce. Not 

 observed on the Waygat-coast, nor in the big valleys leading to the heads of the 

 northernmost fjords (P.). 



Mai ni and: 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. 



V 231. Cassiope tetragona (L.) Don. 



In heath and not too wet bogs. Also in fell-fields up to the horders 

 of the snow fields. 



Very common throughout the whole area. 



Widely distributed in W^est 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 

 Empeinim 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 somo- 

 times also snowless. 



i 232. Harrimanella hypnoides (L.) Coville. Proc. Wash. Ae. 

 Se. III. 1901. p. 575 {Cassiope hypnoides (L.) Don.). 



On spots with long lasting snow, nearly always together with 

 Salix herhacea. 



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.
