plant probably represents the var. arundinacea, such as it is described 

 by Grisebach, 1. c, p. 435 (Vilfa arundinacea, Trinius, Gram, unifl.). 

 Besides, I have also found another quite opposite form which is much 

 slenderer in all parts than the main form; however it grows among 

 the latter. The leaves are only half as broad as in the type, the 

 panicle is smaller, narrower, and less dense. Probably it is such a 

 form which Hooker, 1, c, p. 238, has described as Colp. pauciflorum. 



This grass grew in more or less wet places, in swamps, along 

 brooks, and in clay fields, rarely abundant. Generally the panicle first 

 protruded late in the summer, only in 1902 I saw it in flower about 

 the beginning of August. 



Occurrence. Grinnell Land: Discovery Harbour, Shift Rudder 

 Bay (Hart, Greely). Hayes Sound region: Twin Glacier Valley (870), 

 Cape Viele (863), Eskimopolis (835), Lastraea Valley (853); Cape Ruther- 

 ford in the plateau and the slopes (1154) as also in the vallies. South 

 coast: Fram Fjord in several places (1624); Harbour Fjord, Big Valley 

 (2335), Lake Valley, Spade Point, Barren Vallies (2387), Western sound. 

 Sir Inglis Peak; Muskox Fjord, abundant in clay fields around the 

 Goose and Walrus Fjords, where it was also spread in the higher 

 tracts and especially flourishing there in 1902; specimens from the low- 

 land east of 3rd quarters (3435). West coast; Coal Bay in Baumann 

 Fjord. Here also the narrow-leaved variety was found (3856), which 

 had previously been seen on the south coast in the Big Valley in 

 Harbour Fjord (4249). 



Distribution: Northern East and West Greenland, Arctic Ame- 

 rican Archipelago, Arctic America, Hudson Bay region, Alaska, Pribilof

The species is the most common grass of Ellesmereland and, in 

 fact, is one of the commonest of all plants in the entire country, where
