1 A small, furcate form has occasionally been collected. 2. Crypsinus subfasciatus is a very narrow form, with fertile fronds narrowly linear, to 28 by 0.7-1 cm. It is easily confused with S. setacea, which differs in the still narrower fronds without notches, and the hypodermis with thickened cell walls. 3. Selliguea ceratophylla can be distinguished from S. enervis by the short rhizome, with the phyllopods very close together; the pseudopeltate scales, which are usually more strongly dentate and have a somewhat coarser cell-net than in S. enervis, and the spathulate fronds, which are more gradually narrowed at the base than in S. enervis.
