148 ODONTO- LEJEUNEA. 
versus complicata; lobulus folio triplo fere brevior, saccatus decur- 
rens, subovatus, apice plano rotundato exciso-tridentatus (dentibus 
cellula unica opaca szepe apiculatis); cellule parvule subconformes 
pellucide. 
Foliola foliis vix triplo minora, orbiculata, basi cordata, auriculis parvis 
sinuato-reflexis rotundis, margine integerrima vel obsolete denti- 
culata. 
Flores monoici: 9 in ramis terminales, innovatione brevi rarius iterum 
florifera suffulti. Bracteze foliis longe breviores, ovales acutee den- 
tatee, basi postica minute inflexee vel non; bracteola ovali-rotunda 
suborbiculatave, concavissima, margine toto late recurvo integer- 
rimo. 
Perianthia emersa, f. caulinis vix breviora, cuneato-oblonga, subobcordata, 
compressa, brevirostria, postice altiuscule obtuse carinata, margine 
ab apice ad ? longit. usque anguste alata, ala spinuloso-denticulata, 
(sine dentibus 3 cellulas lata), rostello integro. 
Andreecia ad caulem et ramos lateralia, spiceeformia, folio collaterali sub- 
equilonga ; bracteze sub 6-jugee, subineequilobe ; lobulo = lobi 2, 
involuto-inflato; lobo subacuminato, acuto rariusve obtuso, integer- 
rimo; antheridia bina. 
A beautiful and very distinct plant—apparently the only monoicous 
species among the Odonto-Lejeunew. The leaves are so widely incurved 
at the postical margin, especially towards the apex, that they become 
almost funnel-shaped.
