Salicornaria malvinensis presents considerable diversity of habit in different localities, so much so, that at first I had designated one of its varieties, characterised by the shortness and thickness of the internodes and the comparatively large size of the orifice, Salicornaria megastoma; but further examination has shown no essential differential characters between this and the forms with elongated and slenderer internodes. In the variety from Station 315 (fig. 7) a further exception to the more usual character is seen in the granular surface of the interareolar septa, when the epitheca has been removed.
