leaves when dry with lobes strongly incurved. The plant is interesting as forming a link between Sphenolobus & Cephaloziella and though large for the Cephaloziella the shape of perianth & the occasionally partly connate bracts partly bridge the gap between the two genera The plant has been confused with Belleria so the points of distinction are given below. Affinities Teeth Belleriains Perianth lobulate, with short either few or many Perianth lobulate with long numerous teeth Bracts usually 3 fid rarely over 4 fid Bracts 3 fid ( sometimes 4 fid) with entire marginal lobes sometimes with few to numerous teeth apiculate bracts occasionally connate or partly lobed Leaves concave with incurved lobes lobes obtuse to subacute, rarely leaves caniculate teeth folded into acute sinus lunute to acute acute to acuminate lobes, sinuses acute cells averaging 18 { little if any larger cells averaging 17, very thick at base of leaves. uneven at one walled, usually much larger at base & arrangement the rather thick of leaves walled but without trigones Gemmae bracts absent gemmae bracts constant with gemmae rarely on margins of upper leaves reddish tubercular gemmae Habitat wet floor & flon debris Habitat rotter wood
