Life-form: G. (Root-tuber Geophyte).
On grassy slopes, herb-slopes, heather moors; birch-scrub.
Plor. VI—VIII; fr. mat. (?).
Max. height: 34 cm; average: 17 cm.
Geogr. area: Eur.: Faer.; E.S.I.; throughout most of Europe.—Asia : Temperate
parts.—N. Africa.
Orchis masculus Linn.
K. & M., 1770, p. 210.-—Hooker, in Mackenzie, 1811, p. 126.—Babington, 1871,
p. 330.
Recorded by Hooker from Krisuvík, S., and by Babington (after Solander) from
Hafnarfjörður, S.W.—The specimen has evidently been O. maculatus which is
common in S.W.
Orchis Morio Linn.
K. & M., 1770, p. 210.—Baring-Gould, 1863, p. 434,—Babington, 1871, p. 330.
Recorded by K. & M., loc. cit., and accepted by Babington. Baring-Gould gives
the locality Grímstunga. It has most certainly not been found in Iceland and should
be excluded from the flora.
Salicaceae.

Icelandic : Blæösp. Danish : Bævreasp. English : Aspen.
P. tremula was first found by Mr. Stefán Kristjánsson at Garður in Fnjóskadalur,
N., in the year 1914, see Stefánsson, 1914, loc. cit.; it was growing in birch-scrub,
and the individuals were low, mostly prostrate shrubs, the erect branches attaining
a height of only some few cm. No flowering specimens were found. Stefánsson, 1924,
p. 83, mcntions the Aspen as cultivated in gardens in some few places. It is found
growing spontaneously only in the above-mentioned locality in Fnjóskadalur east of
Eyjafjörður.

Icelandic: Grávíðir. Danish: “Graapil”, Blaagraa Pil. English: Northern Willow.
Very common in all parts, in the lowland as well as the central highland. To
be found even in the most barren and exposed localities in the mountains. A very
polymorphous species, varying much in respect to the hairiness and form and size
of the leaves. In many cases the specimens are evidently of hybridogenous origin.
