XII. LEPIDOZIA, Dum. 
Recueil (1835) ; G. L. et N. Syn. Hep. 200 (1845). 
Plante elatiores, raro pusille, albido-vel flavido-virescentes, raro 
viridissimz, dense cespitose, cespitibus depressis, rarius erectis 
pendulisve. Caules in plerisque validi, pulchre plumeformes, 
pinnati vel bipinnati, facie postica fructiferi ; ramé fol/ost pro m. 
omnes laterales, plus minus deorsum arcuantes, interdum apice 
attenuato radicantes; rarius, et in speciebus pusillis precipue, 
accedunt rami postici normaliter foliosi, vel frequentius ad flagella 
radicellifera redacti. Folia incuba, parvula, in aliis speciebus pre- 
minuta, plerumque tam lata quam longa, valde obliqua tamen, 
margine antico multo longiore et magis rotundato, decurvo-concava 
vel fornicata, palmatim 4-fida-partitave, raro 5—6-vel solum 2-3-fida, 
laciniis subulatis, ceeterum integerrima vel basi antica paucis spinis 
armata, in paucis speciebus toto margine dentata; cel/ule spe 
parvule (2;—.™™ longz) quadrato-hexagone, inferiores subelongate, 
ad angulos vix incrassatze, cuticula seepe asperula; in Micro-Lepidoztis 
autem minutule oblongo-quadrate. oliola foliis subconformia, 
symmetrica tamen, in Hu-Lepidoziis perpaulo minora, in Micro- 
Lepidoziis autem foliis duplo minora. Flores dioici, in perpaucis 
(inprimis Micro-Lepidoziis) monoici: ? ad caulem, rarius ad ramos, 
hypogeni. Bractee 3-5-juge, appresse, concave, intime foliis 
plerumque subitriplo (in speciebus parvifoliis ad 8-plo) majores, apice 
2-4-fidee, margine denticulatz vel spinosa. P/stillidia 20 vel pauciora, 
sterilia in calyptre basi et paulo altius persistentia. Perianthia 
semper fere prelonga—in ZL. subdichotoma 30-plo longiora quam 
folia caulina(!)—ovato-subulata vel anguste fusiformia, superne obtuse 
trigona, in Hu-Lepidoziis carnosa, ore integerrimo vel denticulato, in 
Micro-Lepidoziis leptodermia, ore ciliato-laciniato. Calyptra 2—4-plo 
brevior, pyriformis oblongave, inferne carnosula, vel in Micro- 
Lepidoziis ubique tenuis, demum bilabiatim rupta. Capsula in 
pedicello valido pro m. breviusculo exserta, oblongo-cylindrica, inter- 
dum calyptra imo longior, ad basin usque 4-valvis, 2—4-strata ; 
cellule columnis parietalibus fulcite, intime fibris semiannularibus 
implete. Hlateres tenues bispiri. Spore minute, leves vel 
asperule. Andrecia sepissime ramulo tenui postico constantia, 
raro (et in Micro-Lepidozis precipue) in ramis lateralibus termi- 
nalia; bractee 5-10-juge, suborbiculate concave, apice plerumque
