a bursting of the latter ; such new shoots have rounded 

 bases, which immediately send down roots, probably 

 they separate in time and continue an independent 

 existence. Lond. Journ. Bot., 1844, 479. 



The fructification of this very distinct species has 

 not yet been seen, but the fronds agree with those of 

 Steetzia or Symphyogynee. Fl. Tasm. ii., 238.

Blyftia Lyellii. End growing in small loose patches. 

 Frond about an inch in length, and scarcely a quarter 

 of an inch in width, with a few short side lobes, or 

 forked at the extremity, waved at the margins, 

 occasionally slightly toothed, with a distinct midrib or 

 nerve prominent on both sides. Fruit seated upon 

 the nerve on the upper side near the middle of the 

 frond. Calyx double, the outer shortest, much notched 

 at the margin, the inner or true calyx, cylindrical, 

 slightly toothed at the mouth, and torn on one side. 

 This species is readily known from Morckia hibermca, 

 by the presence of a decided nerve. Cook's Britt.

No Perianth. 



Calyptra on upper side of often stipulate frond ; nerve narrow. 



Fronds membranous, linear, dichotomously or flabellately 

 branched, stalked, arising from a creeping rhizome, midrib 

 stout. Inflorescence monoecious, or dioecious. Fruit from 

 the nerves, usually at the forks. Involucre a toothed scale. 

 Perianth 0. Calyptra smooth, exserted, coriaceous, fimbri- 

 ated at the apex by abortive plstillidia. Capsule on a 

 slender fruitstalk, 4-valved ; valves often cohering by their 

 apices ; elaters with 2 spiral fibres. Antheridia in the 

 midrib ; peri gonial leaves imbricate, tumid, incised, mem- 

 branous.
