rosea, tenuia pellucida, prelate semiovato-oblonga, truncata ; basi 
postica plerumque semicordata, auricula recurvo-cristata; antica 
recurva, apice explanata, toto margine longissime dentato-ciliata ; 
ciliis sub 40, ad 12 cellulas longis, basi abrupte dilatatis, folii basin 
anticam versus magis contfertis et haud raro_ bipartitis; cellule 
majuscule equilatere. 
Flores 2 plerumque in ramulis terminales, raro innovatione suffulti. 
Bracteze bijugee, perianthio arcte adpresse, margine antico fere 
replicato-recurvee, circumcirca profunde inciso-ciliatee. 
Perianthia (rara) plerumque in ramulis terminalia, e cuneaté basi oblonga 
(quasi lato-linearia) compressa exalata, ore truncato crebre ciliata. 
Andreecia longispica tenuia ; bracteze plurijugee monandre. 
Var? parvifolia. Folia seepius minora et subangustiora, magis dissita, 
basi utrinque subintegerrima, margine ibidem tam recurvo ut cuneata 
videantur, antice edentata vel paucidentata, Perianthia rarissima, 
etiamsi in eodem czespite, ad fluvii Negro cataractas lecto, cum plantis 
? inveniuntur plante ¢, magis pinnatim ramose, ramis andrceciis 
tenuispicis constantibus.—Hab. in planitie ad fluvium Negro, in 
Andibus ad montem Campana, alt. 1200™. Anne eadem erit hiecce 
varietas ac Pl. subplana Lindenb. Sp. Hep. t. 14; Syn. Hep. 37.2? 
Stirps autem a cl. G. A. Lindberg in Brasilia australi lecta, ad Pl. 
subplanam a Gottscheo ipso relata, diversa species est. Ut ut sit, 
nostra forma typica, cum perianthiis ad fl. Bombonasa lecta, forsan 
a forma parvifolia pro diversa specie habenda. 
Exemplaria Lechleriana (No, 2524a !) ad Tatanara Peruvie lecta, sub 
nom. “ Pl. suplana” distributa, a Pl. amazonica certe valde diversa, 
nostre Pl. leptophylle magis aftinia.

Hab. in arborum ramulis fluvii Bombonasa inundatis, ad pedem Andium 
Quitensium orientalem, alt. 400™; etiam in Venezuela boreali ad 
arborum radices rivuli Guayaguaca, fluvio Pacimoni attuentis, irri- 
gatas.

Cuudex in matrice longe prorepens, caules frondiformes horizontales 
emittens. Caules 2~6-pollicares, basi seepe flabellatim divisi, dein 
bipinnati, e ramis inferioribus preelongis in frondem triangularem 
rhombiformemve expansi. 
Folia viridia, interdum flaventia vel olivacea, rarius rufula, alterna im- 
bricata patentia, late semiovata, raro subsemicordata—caulina tamen 
fere semiorbiculata—mareginibus basi valide recurvis revolutisve 
parum decurrentibus, antico fere recto apice rotundato excepto 
integerrima, postico apiceque spinuloso-denticulata, dentibus 10-12 
brevibus inequalibus; cellule parvulie eequilateree subpellucidee. 
F. ramulina longe minora angustioraque, oblonga vel subobovata, 
superne vel apice solo paucidenticulata spinulosave. 
Flores Q in ramulorum apice insidentes, raro innovatione suffulti. 
Bractexe bijuge, foliis ramulinis proximis duplo longiores, perian- 
thium arcte amplectentes, basi postica valde ampliatee, argutius 
spinulosee. 
Perianthia subemersa, cuneato-campanulata, basi turgida gibba, superne 
compressa, hine (raro utrinque) alata vel semialata, ala integerrima, 
ore subobliquo spinosa, spinis confertis flexuosis.
