caulis pluristrate, corticales internis conformes, magis opace, iis 
foliorum inferioribus sat similes nisi subminores. Folia incuba, 
alterna, in paucis opposita, basi plus minus imbricata, apice pro m. 
dissita, decurva, interdum (in sicco precipue) secunda, semper 
obliqua, plerumque falcata, subduplo longiora quam lata, a basi 
semicordato-ovata sensim angustata, in dimidio supero subligulata, 
apice plano semper fere truncato-tridentata—casu rariore 4-dentata 
vel subintegra—in perpaucis zqualiter bidentata, vel (in aliis 
speciebus) inzequaliter biloba; margine in plerisque integerrimo, in 
paucis basi postica spinoso dentatove. Axis folii margini postico 
propior, vitta cellularum majorum elongatarum, in seriebus 
6-12-dispositarum, notata; cetere cellule parve subzquilatere 
guttulate, plerumque sublevissime, pariete ad angulos insigniter 
incrassato. oliuwm dichotomiale anticum, ceteris longius, ovato- 
subulatum integrum. Joliola ubique presentia, foliis subduplo— 
raro 3-4-plo—breviora, caule sat latiora, appressa, plerumque sub- 
rotundo-quadrata, raro longiora, apice truncato persepe 4-crenata- 
incisulave, raro subintegerrima, margine integerrima vel subdentata ; 
in aliis speciebus basi cordata, auriculis interdum spinis armatis. 
Flagella subzequifoliata ; folia minuta tristicha ovata concava, apice 
bidentula, rarius solum apiculata tridentulave, juxta basin radicellas 
longas pallidas proferentia. JJores dioici, utriusque sexus cladogeni, 
ramulis posticis constantes. Bractee Q 3-5-juge, intime majores 
(foliis autem seepe subbreviores) arcte imbricatz concave, orbiculatie 
ovateve, rarius ovato-lanceolate, apice saltem lobulate, laciniatze, 
ciliateeve, subscariose, cellulis majusculis elongatis 4-6-gonis sub- 
vacuis constantes. Pistillidia 10-16. Perianthia ovato-subulata 
fusiformiave, 3—4-plo longiora quam lata preter ad basin subcarnosam 
leptodermia, primum ab ipsa basi tricarinata, carinis latis, sulea 
exaratis, exinde quasi 6-plicata, posterius—fructu maturato repleta, 
carinisque fere obliteratis—interdum subteretia, solum apice con- 
stricto trigona; ore in statu perfectiore ciliis longis, 12-15, peni- 
cellata. Calyptra perianthio duplo brevior pyriformis vel cylindrico- 
oblonga, basi quasi-stipitata 3-strata, pistillidiis sterilibus obsita, 
superne 2-strata. Capsula calyptra duplo brevior, oblonga, sub- 
cylindrica, sub 5-strata; cellule stratorum 4 exteriorum columnis 
parietalibus fulcite, extimi duplo majores tesselate, intimi (quinti) 
fibris semiannularibus notate. Hlateres tenues subobtusi, sporis 
minutis duplo angustiores. Amenta 3 folio postico axillaria, brevia 
incurva; bractee 5-raro ad 10-juge, ovate concave vel subcom-
