82 SrTicto-LEJEUNEA. 
Andrecia vel ramulum totum folio caulino sublongiorem, vel rami pri- 
marii apicem tenentia; bracteze 6-10-jugze arcte imbricate equaliter 
biloba. ; 
Inter Lejeuneas insignis, *solumque cum Platy-Lejeunea, e fl. 2 later- 
alibus, innovatione simplice suffultis, necnon bractea altera equiloba 
comparari potest; differt vero hee colore badio; caule flaccido pauci- 
rameo; foliis, etc. epunctatis; sed preecipue perianthiis margine ciliato- 
cristatis, apice exauriculatis. Revera Neuro-Lejeunee (quam videas) 
multo magis affinis est. 
Hab. In fruticum ramis, in sylvis opacis, secus rivulos preecipue. 
Distr. In sylva Amazonica fere tota, in Andibus humilioribus Peru- 
vianis et Aiquatorialibus, cordillere tam orientalis quam occidentalis, 
ipse legi. In tota America tropica, ab insulis Antillanis per Braziliam 
ad Chili usque, reperta est.—Stirpes mere Americane, in Oriente 
nondum vise.

Syn. Heb. 322. 
Hab. in fruticum ramulis secus rivulos, rarius in arborum cortice, per 
Andium: orientalium radices, nusquam supra 600 m. ascendens: locis 
Tarapoto, fl. Bombonasa, Pastasa, etc.; in planitie (quoad formam per- 
fectam) rarior: fl. Negro juxta montem Cocuz (inter Braziliam et 
Venezuelam litem), ete. 
F 1:2x°85, 1:1 ‘8, ‘8x °6; lob 1—*125; ¢ 3; f'* ‘8x12; bractew lob 
*8x°55; br 65x ‘55; per 1:05 x ‘9, auricule °35 x °5; caps *35™™. 
Elata, pallide viridis, albescens, raro rufescens, procumbens stratificata. 
Caules e caucdice repente fere liberi, arcte plumeeformi-pinnati et sub- 
bipinnati, ramis alternis, frondem 2-3 pollices longam, } poll. latam, 
ambitu lanceolatam, efformantes. 
Folia late imbricata subplana, tenuia, pellucido-punctata, patula, semi- 
cordato-ovata v. ovato-oblonga rotundata, basi antica caulem late 
transeuntia, postica sinuato-lobulata; lobulus minutus foliis 10-plo 
brevior ovoideus convolutus, sinu decurvus itaque quasi corni- 
formis, apice (occulto) acuto acuminulatove; cellule minutule sub- 
pellucide leptodermes, subeequilatere, inferivres subelongate. Inter 
cellulas normales interpositee sunt alice duplo majores —pellucide, 
annulo chlorophylli opaco in ambitu—ad ocellorum instar, cellulis 
normalibus 4 v. pluribus dissite, per totum folium sequaliter sparse. 
Eodem modo foliola, bracteze perianthiaque ocellata sunt. 
Foliola imbricata foliis eequimagna sed transversa, dimidio latiora quam 
longa, cordato-reniformia, apice lato recurva. 
Flores dioici: 9 quasi-laterales, in ramo primario secundariove brevis- 
simo terminales, innovatione simplice pro more brevi (foliis sub 5- 
jugis) suffulti. Folia rami ? infrafloralia minuta unijuga orbiculata. 
Bractez foliis multo minores complicate; interna (innovationi adnata) 
bipartita; lobis obovatis rotundatis, inferiore duplo breviore angus- 
tioreque, externa duplo minor obcordata, paulo ultra } emarginata, 
lobis subeequalibus semiobovatis.
