crenulata, margine toto (apicis preecipue) recurvulo, basi externa 
fasciam radicellarum linearem proferentia. 
Flores dioici; @ in ramis primariis, necnon in ipso caule, terminales, 
plerumque ex innovationum dichotomia, raro innovatione unica 
(simplice proliferave) suffulti. Bracteze foliis subminores profunde 
bilobz complicate, lobis subineequalibus, vel fere equalibus, 
oblique obovato-lanceolatis acutis angulato-denticulatis—raro spinu- 
losis, lobulo apice haud raro bidentato; bracteola obovato-ovalis ad 
i bifida, segmentis acutis conniventibus, distanter angulato-denticu- 
lata spinulosave. 
Perianthia subimmersa oblongo-pyriformia vix rostellata 5-carinata, 
carinis apice latiore rotundo-prominulis levissimis. Calyptra pyri- 
formis, perianthio duplo fere brevior, stylo ultra perianthium alte 
emerso. 
Lejeunea cerina L et L.* (Syn. Hep. 391) folia habet minora, acute 
tenui-acuminulata, lobulo turgido; foliola, pro foliorum ratione, majora, 
lateribus valide incurvis, rima apicali 5-7 cell. alta.—L. reflexistipula 
L. et L. differt foliis longe minoribus subplanis; foliolis contra pro 
ratione multo majoribus, apice perfecte integris, basi haud cordatis; 
bracteis minus dentatis; bracteola apice integra, nec bifida; perianthiis 
alte emergentibus.

F -8x°6 (sine lobulo); lobul *15-2; ¢ a5; f* “6x *75™™. 
Procumbens, dense stratificata, fulva. Caules 2-3°™ longi, paralleli, 
flaccidi, parum ramosi, seepe ramulis parvifoliis deciduissimis pin-

Folia contigua v. parum imbricata, fragilia, a basi brevi erecta, cum 
lobulo in sacculum parvum semiparaboloideum coalita, subdiver- 
gentia, semicordato-ovata-oblongave, apice decurvo obtusata, margine 
parum celluloso-crenulata; lobulus 5-plo brevior, margine trans-

Majuscula pallida tenera; caules breves parum vageque ramosi. Folia 
imbricata late patentia decurvula, semicordato-ovata acuminulata, apice brevi

Plantam Taylorianam autotypam, in monte Corcovado Brasilie lectam,
