LopHo-LEJEUNEA. 119 
Suseenus X1.—LOPHO-LEJEUNEA. 
Lejeunee species Syn. Hep. 
Mediocris, rufescens, raro virescens, siccando seepe fuscidula, in plagas 
densas spe latas effusa, raro stratificata, in arborum cortice, ramu- 
lisque, nec raro aliis hepaticis muscisque irrepentes. Caules 1—2- 
pollicares pinnatim ramosi; rami inquilongi spe assurgentes, alii 
apice indiviso florigert. 
Folia 0°5-1-0™™ longa imbricata, subdistiche patula, apice solo decurva 
plus minus oblonga raro subrotunda, interdum subfalcata, pro more 
rotundata raro subacuta, semper integerrima; lobulus mediocris, in 
una eademque specie major et minor, inflato-saccatus (rarius sub- 
planus) apice v. acuto incurvo v. sepe lato obtuso in lobum sensim 
transiens; cellule parvule—in unica specie fere magnee—paulo in- 
crassatee, subplanze. 
Foliola pro more magna, raro tamen folia equantia, reniformirotunda, 
planiuscula. 
Flores monoici rarius dioici: 2 in ramo brevi longioreve terminales, 
sine ullainnovatione. Bractez foliis caulinis majores serrulatee—raro 
laciniatz lobulo parvo,‘interdum subnullo; bracteola magna sepius 
orbiculata patelliformis apice lata integra. 
Perianthia plerumque emersa pyriformis turbinatave sat compressa, 4-cari- 
nata, carinis omnibus siepissime late alatis, alis profunde laciniato- 
cristatis. 
Andreecia longispica, ramum totum v. ejus apicem solum tenentia. 
Platylejeunea, quoad species minores, Lopholejewnew sat similis, differt 
habitu serpentino; caulibus pro more elongatis paucirameis; foliolis 
decurrentibus; floribus 9 minutis, ramulo brevissimo laterali constantibus, 
semper tamen innovatione parva suffultis ; bracteis minutis fere equaliter 
bilobis ; perianthio parvo magis compresso, aliarum imo complanato—mar- 
gine plus minus laciniato-ciliato, faciebus (postica precipue) apicem 
versus pro more carinulatis cristulatisque. 
L. harpaphylla 8. facie Lopholejeunee persimilis, differt perianthiis obeor- 
dato-triangularibus triquetris, carinis fere levibus valde rudimentarie 
alato-scaberulis; necnon foliorum lobulo eroso-crenulato; bracteolis apice 
angusto bidentalis. Probabiliter subgenus proprium constituerit, sociis 
L. Crescentie L. et G., L. Lehmanniana G., e. a. perianthiis trigonis a 
Lopho-Lejeunea eeque ac ab Acro-Lejeunea distinctum. 
Hab. In arborum cortice vetusto seepeque in fruticum ramulis, raro 
in rupibus, aliis Lejeuneis plerumque consociata ; extra planitiem haud 
visa. 
Distr. Species sub 12 adhue recognite regionibus tropicis omnibus 
disperse ; in America ab Antillis et Mexico ad Brasiliam australem ; 
in oriente per insulas Malayanas et Oceanicas. In sylva Amazonica— 
nullibi in montes ascendentes—4 species legi, quarum 1 (L. L. Sag- 
reana Mont.) in insula Cuba, in Guiana, etc., crescit, ejusque var. 
cyclostipa ad ostia tam fl. Amazonum quam fl. Nigri Africz; altera, 
L. L. subfusca N. etiam in Chili (?), Java et Mauritii insula inventa 
est. Eidem subgeneri probabiliter adscripta est L. plicatiscypha H. f. 
et T. e Nova Zelandia.
