Foliola caulina remota foliis fere 5-plo minora orbiculata denticulata, 
apice ad 3-} emarginato-bifida, raro integra; ramea multo majora, 
superiora folio adjecto sepe perpaulo minora, argutius denticulata 
fere ad 4 bifida; ommia ex alis recurvis cochleata, haustorium dis- 
coideum parvum pallidum gerentia. 
Flores dioici: 9 in ramo spe brevi terminales, innovatione simplice 
suffulti. Bracteze foliis multo minores lanceolate serrulatz basi 
breviter complicate, lobulo lineari-rhomboideo; bracteola ovalis sub- 
bifida integrave denticulata (in fl. sterili ad $ bifida.) 
Perianthia emersa obcordato-triangularia valde compressa, supra depressa 
subtus convexo-carinata vel solum gibba, margine supra medium 
peranguste alata serrulataque. 
Andreecia longispica ramulo tenui constantia; bracteee minute subcon- 
tiguie arcte complicate solum basi ventricose. 
Foliorum lobulus medio seepe in literee S formam sinuatus, 
Var. megalostipa, rufa planissima siccando hand crispata, foliolis (superiori- 
bus preecipue) foliis paulo minoribus ad 4 bifidis.—Hab, ad fl. Bom-

Plante pusilla, seepe albicantes, prostratie v. laxe reptantes. Caules vage 
v. subpinnatim ramosi, ramis pro more paucis. 
Folia parva parum imbricata decurvula sepissime acuta acuminatave, e 
cellulis marginalibus conicis crenwlata serrulatave, interdum facie 
muriculata; lobulus 2-6-plo minor inflatus, rarius obsoletus; cellule 
gy—sip™™, plerumque parvule, pellucide, pariete ad angulos subin- 
crassato, marginales (raro omnes fere) conice, subbasales seepe multo 
majores. 
Foliola parva minutave subrotunda fere semper integerrima, in pluribus 
adusque (in paucis ultra) medium bifida; radicella fasciatae peni- 
cillateeve—nunquam in discum radiantes. 
Flores in plurimis monoici, in paucis dioici, Rami 9 in aliis sp. brevis- 
simii simplices, in aliisinnovantes. Bractez foliis plerumque minores 
parvilobulatee, argutius denticulate spinuloseeve; bracteola bifida. 
Perianthia iis Odonto-Lejeunee sat similia, sc. obcordata compressa postice 
obtuse l-carinata, rarius tamen alata, plerumque margine solum 
muricato-spinulosa. 
Andreecia ramulo tenui cauligeno constantia, raro terminalia; bractes 
parvulee 2—20-jugee diandre. 
Obs. Odonto-L. Peruviana nexum cum Priono-Lejeunea preebet, differt 
autem statura elatiore; foliis magnis seepe argute dentatis; foliolis den- 
tatis, aliis bilobis, aliis solum emarginatis v, etiam (sed rarissime) in- 
tegris. 
Hab. In arborum foliis, ramis truncisque, sepe supra alias hepaticas 
repentes; planitiem et montes humiliores diligentes,
