Note 278 — Chapter XXIV

This minute lichen, mentioned at chapter xxxii, is the most Arctic, Antarctic, and Alpine in the world; often occurring so abundantly as to colour the rocks of an orange red. This was the case at Bhomtso, and is so also in Cockburn Island in the Antarctic ocean, which it covers so profusely that the rocks look as if brightly painted. See “Ross’s Voyage,” vol. ii. p. 339.
