tenues bispiri. Spore minute, diametro eclateres vix excedentes, 
minute scaberule, 
Andreecia in caule ramisve terminales vel subterminales; bractec 
paucijuge, foliis proximis vix diverse; antheridia solitaria magna 
globosa stipitata. 
Cum typo advenit forma brevior, magis robusta, fulva, seepe simpliciter 
pinnata, foliolis plerisque 6-fidis.

Plante elatiuscule vel pusilla, interdum minute, prom. depresso- 
cxspitose, latas plagas sistentes; virides vel haud raro albicantes 
flavideeve, rarius badiz lurideve, in perpaucis speciebus roseo picte. 
Caules prostrati vel assurgentes, nunc validi, nunc tenuissimi, 
diverso modo ramosi; alii rami, floriferi pracipue—in quibusdam 
generibus omnes—postici; in unico genere Anomoclada rami 
foliosi et floriferi antici, radicelliferi postici, nullo lateral. Folia 
alterna, in perpaucis opposita, omnimodo inserta, omniformia fere 
inter setacea et orbiculata, raro ad squamulas minutas redacta, in 
Cephalozie subgenere Pteropsiella in limbum aleformem connata ; 
in paucis integra, in plerisque biloba, in plerisque aliis 3—4-lobata- 
dentatave ; margine integerrimo vel dentato, plano vel incurvo 
(nunquam, ut videtur, recurvo); cellule persepe majuscule vel 
mediocres, in perpaucis preminute. oliola in aliis nulla vel 
adventitia, in aliis parva minutave, in perpaucis (Lepidozie speciebus 
precipue) foliis lateralibus parum minora. lores in speciebus 
robustioribus semper fere dioici, in pusillis sape monoici (raro 
paroici); feminei vix non constanter in ramo hypogeno, brevis- 
simo vel longiusculo, in quibusdam Cephaloziis autem in ipso caule, 
terminales. Bructec trijugee vel pauciores, tristiche, rarissime solum 
distichze, foliis rarius conformes, seepe majores, magis fisse, intime 
interdum in cyathum plus minus alte connate, a perianthio autem 
libere. (In genere marsupialio, Kantia, bractese in etate etiam 
parve restant, squamiformes, marsupii orificlum circumstantes), 
Pistillidia 10-20. Perianthiwm (Kantie excepto) semper presens, 
tam ab involucro quam a calyptra perfecte liberum, trigonum—a 
fronte subplano compressulum, angulos duos laterales, tertium 
posticum ostendens—raro 3-6-gonum ; angulis plicisve constanter 
inermibus, superne argutioribus, unde peranthium (initio seepe hians) 
apice plus minus subulato-constrictum evenit, ore repando, dentato
