The $. obovata, Hook. fil. et Tayl., corresponds with what is here understood as the fertile state of S. rhizobola, 
and, as might be expected, the attenuations at the apices of the divisions of the fronds are absent. The calyptra, 
although described by Dr. Taylor as ventral, is truly dorsal, as in all others of the genus. $. pulchra, Tayl., de- 
scribed with the margins of its fronds entire, has them certainly dentate; although the teeth are short and remote, it 
scarcely differs in appearance from the preceding. The specimens gathered by Dr. J. D. Hooker are finely in fruit, 
and the fertile stems are mixed with others corresponding in structure, but differing in habit, being prostrate, and 
rooting at the apices, like the plants figured in * Musei Exotici. The fertile stems are short and ascending, the 
divisions scarcely exceeding the third of an inch in length, and rounded at their apices, thus having an appearance, 
if seen separately from the creeping fronds, of being altogether a distinct plant.

Sufficiently different from any other Tasmanian species. From the description of the capsule it may be doubtful 
if it truly belongs to this genus.
