Matricaria Chamomilla Linn.
Benguerel, 1861, p. 450.—Babington, 1871, p. 313.
H.H. contains a fragmentary specimen in flower of this plant, labelled “Reykjavík,
ded. Halldórsson Friðriksson”.—Benguerel, loc. cit., mentions M. Chamomilla, but
this is most probably due to a mistake. Where it is really found in Iceland, it is
only as an accidental introduction; it may even now and then be found at the
settlements in Greenland (cp. M. P. Porsild in Medd. om Gronl. vol. 92. No. 1,
p. 20, 1932).

Camomile.
This species was first found at Reykjavík (Bj. Sæmundsson, 1902). It was
originally accidentally introduced, but it has held its ground year after year, and
