Occurrence of Asparagopsis armata Harv. on the Coast of Cornwall

Abstract

THE occurrence of Falkenbergia on a shore of Lundy Isle was reported last year by Harvey and Drew¹, and since then I have received specimens of this inconspicuous alga from Miss M. de Valéra collected in November 1939 from near Galway Harbour and in July 1941 at Muigh Inis, Ireland, as well as another from Miss S. M. Lodge from Lough Ine, collected in July 1949. In addition, I myself have found Falkenbergia cast ashore in August of this year at Falmouth and also at Kennack Sands on the Lizard Peninsula. It must be regarded, therefore, as a not uncommon component of the British marine flora. Although well developed, the Cornish plants were sterile, like all others examined.
