The Flora of Disko Island and Adjacent Coast of West Greenland. 103 
A 202. Potentilla alpestris Hat. fil. (Syn. P. maculata Pourr.; 
P. Langeana Ryopp.). 
In herb-mats and copses. 
Disko: Rather common on the south coast. In Diskofjord on the north coast 
and at the hot springs of the south coast. On the north coast of Mellemfjord to 69°45’; 
from Mudderbugt to Kvandal behind Ujaragsugssuk 69°45’ (P.), 
Hare ©. The south coast, scarce 70°22’ (P.). 
Mainland: Ritenbenk 69°45’ (V.); Jakobshavn (Sor.); Egedesminde (Sor.). 
On the mainland s. o. Ikamiut island 68°23’ common (P. & E.). 
A southern type, the above mentioned localities represent the 
northern limit of the species in West Greenland. 
All the mentioned localities in the lowland. 
Abundantly flowermg and fruiting. 
Hibernates covered by snow. 
Rather variable, some of the forms certainly depending on the 
quality of the habitat. Var. hirta Lange is in well-marked forms a rather 
deviating type, by Ryppere |. c. p. 179 considered an independent 
species: P. Langeana Rydb.; it is distinguished by several flowered 
cymes and the long pubescence of the leaves, but also by the more acute 
teeth, the longer and more acutish bractlets and narrower sepals. This 
form seems to be more common than the mainspecies; it is sometimes 
very tall and robust. 
As most of the numerous European forms of the comprehensive col- 
lective species P. alpestris are constant in culture, the same may per- 
haps be the case with this. 
P. rubens Vill. is recorded from Godhavn by RowLer & WIEGAND; 
but as this Mediterranean species has been found nowhere else in Green- 
land | am inclined to refer the plant to the form-circle of P. alpestris. 
Bs 203. Potensilla Frieseana Lancer. 
This remarkable plant has only once been recorded from Kuaner- 
ssuit in Diskofjord 69°35’ (Th. Fr.) 
In vain I have searched for it here during many years. Of the re- 
cent monographers of the genus RypBeERG accepts it as a valid species 
rather deviating from the other ones; but Tu. Wotr reduced it to a 
form of P. alpestris. The most remarkable characters is the dense glan- 
.dular pubescence. But as P. emarginata also normally shows a glandular 
covering (see Apromeir |. c., KNup Jessen, Medd. om Grl. 37, p. 39). 
I feel rather inclined to consider P. Frieseana a luxuriant form of this 
species or a hybrid between P. emarginata and P. alpestris, both grow- 
ing plentifully at Kuanerssuit.
