29. STEETZIA, Lehmann. 
Frond linear, more or less dichotomously branched, with a midrib. In- 
florescence dioecious. Involucre at first terminal, dorsal by the subsequent 
elongation of the frond, seated on the midrib, cupshaped, torn. Perianth 
tubular; mouth toothed. Calyptra as long, torn at the apex. Capsule on a 
slender fruitstalk, ovoid ; elaters free, with 2 fibres. Antheridia dorsal, on 
the midrib, covered by minute fimbriated leaves. 
A considerable genus, scattered over both the temperate and tropical regions of the globe.

compared by Mitten with large forms of Melzyeria f areata. 
30. SYMPHYOGYUA, Mont, and Nees. 
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, fimbriated at the 
apex by abortive pistillidia. Capsule on a slender fruitstalk, 4-valved ; valves 
often cohering by their apices ; elaters with 2 spiral fibres. Antheridia in the
