Abstract
THE terrestrial Chætophoraceous alga, Fritschiella tuberosa, which was first discovered1 by Prof. M. O. P. Iyengar in India from soil in drying rain-pools in Madras and Mysore, and later recorded from Fyzabad2 and the Benares district3, has now been found at Khartoum, in the Anglo-Egyptian Sudan. It occurs there during August, September and October in drying silt on the banks of the Blue Nile as the river recedes after the summer floods. It has been found in this situation for three years in succession with the alga Protosiphon botryoides (Kutz.), Klebs., var. deserti, Nayal, and grows in such profusion that the bare silt assumes a distinctly green coloration.
