DRrEPANO-LEJEUNEA. 187 
Folia dissita, primum assurgentia dein apice valide decurvo-hamata, 
elongata, 2-4-plo longiora quam lata, pro more oblique lanceolata 
acuminata acuta—raro latiora ovataque—lobulo ovato-fusiformi tur- 
gido (raro obsoleto) aucta, margine (antico preecipue) spinulosa erenu- 
latave, in paucis speciebus insigniter pectinatim laciniata, levia 
papulosave; cellule parvee vel fere minute subconformes—raro paucee 
subbasales majores ocellum sistentes—pellucide, pariete vix incras- 
sato. 
Foliola minuta, in sp. Austro-Americanis a basi integra brevissima cuneata 
biparita, cruribus 3-5 cellulas longis late divergentibus (in unica L. 
palmata erectis); in L. hamatifolia, Europea, solum bifida, basi 
integra altiore, cruribus brevioribus. 
Flores dioici, in perpaucis monoici: 9 in ramo brevi terminales, innova- 
tione simplice suffulti—in unica L. campanulata in caule ramove 
iteratim innovando-florifero. Bracteze foliis longiores seepeque multo 
latiores bilobee concave, vix complicates, lobis parum ineequalibus 
spinulosis; bracteola angusta seepe subovalis spinulosa, ad }—% bifida, 
segmentis acuminatis, pro more cum bracteis altiuscule connata, 
Perianthia ssepius emersa 5-gono-obpyramidata, rostellata, carinis in per- 
paucis inermibus, in plurimis superne spinulosis apiceque in cornu 
breve subhorizontale pungens dilatatis. 
Andreecia longispica; bracteze majusculee contiguee rotundo-naviculares 
subeequilobee, ad carinam e cellulis exstantibus pulchre moniliato- 
papulosee, monandre. 
Hab. Species Amazonicz et Andinz in foliis vivis, filicibus, et licheni- 
bus repens, necon alias hepaticas infestans, nunquam in cortice; species 
unica Kuropzea autem in fruticum cortice et in rupibus crescit. 
Distr. In America eequatoriali 8 species legi, quarum 6 Andium juga 
sylvatica, alt. 1000-3000™ habitant, 2 solum in planitie visee, earumque 
1 (L. palmifolia N.) in sylvis flum. Amazonum borealibus, super truncos 
prostratos, ad arborem pedem, etc. viget, semper autem caulibus suis 
tenacibus implexo-ramosis, foliorumque laciniis uncinatis, alias Lejewneas, 
Bazzanias, etc. arcte amplectens, imove denique exstirpans. Altera species 
amazonica est L. capulata Tayl.! (quam nullo modo a planta Taylori 
originali, in Oware Africze lecta, distinguere possum): probabiliter inter 
“L. hamatifolie vars.” ‘Synopseos Hepat.’ jam enumerata. L. hamati- 
folia Hook. vera autem, Europe occidentalis, ins. Britannicarum preci- 
pue, incola, nusquam in America mihi obvia fuit. LZ. inchoata Meissn., ex 
ins. Antillis, certe eidem subgeneri pertinere videtur; alize species sunt 
L. Ternatensis G., tenuis N., tridactyla G., trematodes N., dactylophora 
N., muricata G., insulis Malayanis et Oceanicis indigenz, plereeque L. 
paliifolie arcte affines.
