tigui. Folia oblique vel fere longitudinaliter inserta, plerumque tenera, 
integerrima, denticulata, vel dentato-ciliata. Foliola in plurimis specie- 
bus obyvia, in paucis nulla. Flores ? monogyni. Innovatis pes sub- 
florales, solitariz, vel binge et opposite, in plerisque adsunt, bracteis 
intimis adnate, in aliis autem carent. Bracteze uni-raro pluri-jugee, 
planilobe. Pedicellus idem fere Jubule, cellulis axialibus 4-seriatis 
(interstitiis formam crucis ostendentibus), periphericis 12- vel 16-seriatis. 
Capsula (pro more pallida) facie interna spongiosa.

Plante pro more elatz, raro pusillee, depresso-czespitosee et strati- 
ficatze, sepe pendule, firmiuscule, colore raro viridi, plerumque 
rufescente badiove, interdum fere nigro, in paucis roseo tincto vel 
omnino sanguineo, haud raro nitido. Cawles validi teretes opaci, 
cellulis parvis conformibus pluristratis conflati, pinnatim ramosi ; 
rami foliis exacte axillares, basi tam lobo quam lobulo contigui, raro 
apice bifurci, altero ramulo ad involucrum ? abbreviato, altero 
interdum apice iterum (subinde iterumque) florifero ; innovatio vero 
subfloralis nunquam adest. olia basi brevi transversa (antice per- 
paulo sursum vergente) inserta, complicato-biloba ; lobus anticus 
major, oblique ovatus vel suborbiculatus—nunquam angustus—con- 
vexus, incubus, persepi basi antica semicordatus, integerrimus, 
rarius apice denticulatus; lobulus cucullatus, galeiformis, vel saccatus 
(campanulatus digitiformisve), haud raro evolutus ovato-lanceolatus, 
revera pro more bipartitus, lacinia intima (juxta caulem) parva 
minutave, triangulari, subulata styliformive. Cellule plerumque 
parvulz, in aliis minut, in paucis mediocres, in nullis magna, in 
omnibus fere subzquales, globoso-hexagone, pariete incrassato, 
trigonis ad angulos, interdumque (cellularum inferiorum) quoque ad 
latera, conspicuis. olium avillare (sc. ramorum insertionem ob- 
velans) quoad lobum ceteris foliis conforme, lobulo autem majore, 
distincte duplice, bifido vel ad basin usque partito, laciniis sube- 
qualibus vel caulinari imo majore. oliola semper presentia, sat 
magna, foliis tamen minora, orbiculata, oblonga, vel cuneata, basi 
seepe cordata vel crispato-auriculata, raro subdecurrentia, apice 
bifida (in perpaucis integra), e tergo radicellas breviusculas stellatim 
patulas rarius proferentia. Flores dioici vel monoici (raro paroici). 
Andrecia varie posita, sepissime ramulo abbreviato, globoso, oblongo 
vel cylindraceo constantia ; bracteze conferte, 2-(raro 3-4-)andre. 
Gynecia semper terminalia, acrogena vel cladogena. Bractew 2-5-
