I havenot had an opportunity of examiningone of these specimens, but I grate-fully acknowledge the kindness ofProfessor Ewart in loaning me aspecimen from the National Herb-arium, Victoria, collected in sub-saline p. [places?], Little Desert,Lowan, North-west Victoria. Themegaspore measurements of thisspecimen agree with those fromSouth Australia. The species may be said to be common in parts of the National Park,growing in damp sandy soils derived from decomposedCambrian quartzites. The habitat and soil is similar at. Fig. 2.

At Victor Harbour the soil is also sandyalluvium overlying the glacial deposits near the mouth of theHindmarsh River. At this last station some of the specimenswere found submerged to a depth of 6 cms. in a waterholecaused by the removal of a tree stump. This pool onlycontains water during the wet season. Most plants, however,were growing in the open some distance from standing neither of the localities about Adelaide has Isoetes beenfound submerged. The method of growth of the plant isincidentally referred to below in discussing the plant com-munity in which Phylloglossam occurs at Belair. It is unfortunate but inevitable that of the numerousinvestigators of Phylloglossum only one (Thomas
