Seems to be common along the sea coast in most parts of Iceland. Along the
south coast, however, it is rare between Vík and Hornafjörður.
Under the subsp. borealis are established 2 varieties:
1. var. virescens (Lge.) Holmb., loc. cit., p. 182, with higher culms, up to 40 cm,
longer and narrower leaves; panicle brighter, scarcely violet tinged, branches rough,
straight and rigid, erect, later on spreading, ultimately deflexed. Rather rare.
2. var. vegeta Holmberg, loc. cit., p. 183. Stout, up to 90 cm high, coarser, with
broader leaves; panicle prolonged, with many spikelets. Here and there.
Life-form: H.
Around inhabited places, dumping grounds, below bird-cliffs, and on manured
localities, usually near the sea-coast.
Flor. VI—VII ; fr. mat. VII—VIII.
Max. height: 40 cm ; average : 20 cm.
Geogr. area : (coll. spccies) N. Am. (?).—Greenl. : W. 60°—78°20'. E. 60°—65°37\

Until the last few years S. coerulea has been found only within a very limited
area near Reykjavík, S.W., where it is rather frequent. In 1935 it was also found
