Ascending from the coast to the snow-line. 
Abundantly flowering and fruiting. 
Often snowless during winter. 
4 50. Poa nemoralis L. var. glaucantha Вгутт. 
Almost the same applies to this southern type as to Р. laxa. LANGE gives the 
distribution between 60° and 69°20’ and this GELERT approves by his sign!; hut in 
Н. H. revised by GELERT no specimens occur from localities north of са. 67°. The 
localities recorded north hereof are: Disko (WALKER), some localities near Jakobs- 
havn (В. Br.) and Christianshaab (W. & H.). 
In addition I have referred to this species a grass from a few localities in N. 
Stromfjord: Eqaluarssuit 67°36’ and Ipiutarssuaq 67°44’ (P. & E.). 
The plant was here growing in thickets and seemed to have been 
fruiting the preceding year. 
The above mentioned localities are from the lowland. 
" Hibernates under thick layers of snow. 
Puccinellia. 
The species beionging to this difficult genus have recently been 
thoroughly studied by various American and European botanists. Thus 
М. Г. FERNALD and С. A. WEATHERBY in Rhodora 18. 1916 gave a 
description of the species in Eastern North America, accompanied by 
extensive synonymic and excellent figures. And on the European and 
Arctic species Dr. О. В. HoLmBERG, has published various smaller 
papers as precusory studies for an exhaustive monograph. 
Аз I have had an opportunity of comparing ту М. 5. and my field- 
notes, but not my herbarium-plants, with the material in H. H. revised 
and labelled by Dr. HoLMBERG, it seemed desirable to bring the names 
of the species here treated of in accordance with the nomenclature of 
HoLMBERG’s monograph, still unpublished. For that purpose my friend 
Dr. Ногмвевс kindly provided me with a list of the combinations 
to be used. | 
For the explanation of those combinations and their synonyme, 
in shorthy for the entire systematic part of the classification, the reader 
is referred to HoLmBEre’s own work soon to be published. 
V 51. Pucinellia Vahliana (Lırsm.) Scripn. & Merr. (Incl. Glyceria 
Kjellmani (LANGE). 
In open spots in the heath, on newly formed moraine and on clayey 
and sandy slopes, but not halophilous. 
Disko: The Northland from about 70°0’ on the coast of Waygat and around 
to the Nordfjord gathered from several localities, no doubt rather common (P.); in 
the great valleys from the head of Nordfjord 69°50’ (P.). Hare Ø (Nath.; P.).
