majoribus; bracteis distincte lobulatis, lobo latiore; denique perianthiis 
latioribus minus alte emersis.—Quum specimina perpauca habui, de flores- 
centia minus certus sum. Probabiliter a L. Méilleriana haud bene 
diversa erit, et tam una quam altera ad L. subfuscam, pro varietate, re- 
ferenda.—Forma Le}. subfusce N. typica, primum in terris Malayanis in- 
venta, postea etiam e Chili allata fuit, fide cl. auct. ‘Synopseos Hepati-

Hab. Ad flumina Amazonum (Santarem), Negro (S. Gabriel et S. Carlos), 
Uaupés (Panuré), Bombonasa, etc., constanter in cortice, ramulorum 
preecipue. 
F 10x 6, ‘9x ‘55, lob 4-5, c sy—gs; fit 5x5, 55x55; br 105K +4; 
bee 10x 6; per 1-1. :8, 1-1 x -65™™. 
Tenella pallide viridis pellucida, siccando fuscidnla. Caules pollicares 
subrepentes, ramis assurgentibus inequilongis, pro more brevibus, 
subbipinnati. 
Folia subimbricata oblique et subfaleato-oblonga ovaliave obtusata rotun- 
datave, raro superiora acuta, basi antica rotundata angustave—raro 
semicordata, postica decurrente, recte complicata; lobulus duplo 
brevior semiovatus folii medium versus sensim (sine ullo dente 
prominente) transiens, subplanus, eroso-crenulatus; cellulae mediocres 
(basales sensim majores, marginales duplo minores et quadratz) 
subelongatz, pariete ad angulos et media latera incrassato, chloro- 
phyllo parco. 
Foliola subimbricata, superiora sensim crescentia, dimidio folio eequi- 
longa, rotundo-quadrata-obovatave, retusula—raro emarginata—re- 
panda subplana, inferiora radicellas longas in fasciam colligatas 
proferentia, superiora pleraque arhiza. 
Flores monoici: ? in ramis seepe elongatis terminales, sine ulla inno- 
vatione. Bractez foliis caulinis sublongiores erecto-patentes oblique 
lanceolate acute, a basi ad medium usque plica perangusta auctee; 
bracteola zequilonga, latior, ovali-lanceolata obtuse carinata, acuta 
bidentulave. Foliolum infraflorale bracteola paulo brevius, constanter 
bidentatum. 
Perianthia subemersa pellucida obcordato-cuneata compressa, antice de- 
pressa vel parum convexa, postice alte anguste unicarinata, apice in 
rostellum planum abeuntia, margine interrupte subalata, vel solum 
angulata, vel superne dente uno alterove obtuso armata. 
Andreecia caules et ramos terminantia; bracteze plurijuge, foliis sensim 
minores, complicate, basi sola ventricose, planilobee, lobo obtusato, 
lobulo duplo angustiore paulo breviore lineari-rhomboideo sub- 
acuto. 
Forma breviloba, foliis subeontiguis minoribus ligulato-oblongis apice 
variis, lobulo ad plicam 6-plo breviorem semilanceolatam redacto, peri- 
anthio alte emerso, advenit prope 8. Gabriel. 
Forma longiloba, foliis magis confertis, plerisque rotundatis, rectioribus, 
ad vel ultra medium in lobulum involutis, ad fl. Uaupés lecta fuit. 
Tertia forma, minor, tenerrima, foliis plerisque acutis, prope Santarem 
habitat.
