together ; whereas in all other Lejeune the upper lobe of the bract is 
always larger than the lower. The inner bract is either quite symmetrical, 
having the two lobes exactly equal, or the upper lobe is smaller, as in the 
outer bract. 
2. PLATY-LEJEUNEA THNIOPSIS, Spruce. 
Hab. In sylvis fl. Amazonum, preecipue humilioribus, ramulis foliisque 
Vivis adrepens seepeque longe pendula; locis: Pard, S. Gabriel et 
S. Carlos, Yurimaquas, fl. Bombonasa, ete. 
F 26x15, 2°0x 15; lob 4x3; ¢ dy; f'*15x1'8; br 7 et 5 longe; per 
Poe pene 
Elata rufo-badia, strato tenui late repens. Caules 6-pollicares et longiores 
debiles, pinnatim ramosi, aliis ramis brevissimis floriferis, aliis elon- 
gatis fere simplicibus seepe pendulis. 
Folia parum imbricata subdivergentia, siccando vix mutata, maxima, 
semicordato-ovato-oblonga, rotundata vel truncato-rotundata, basi 
caulem late transeuntia, margine antico apiceque incurvula, postico 
(basi apiceque exceptis) valide recurva, prope basin profunde sinuato- 
complicata; lobulus sub 6-plo brevior paraboloideus (axi cauli paral- 
lela, plica transversa) cucullato-concavus muticus; cellule majusculie 
subeequilatere, pellucida, ambitu subopacee, pariete ad angulos 
mediaque latera incrassato, inferiores submajores. 
Foliola subimbricata foliis subminora sed latiora, reniformia longe decur- 
rentia, apice retuso recurvuloque repanda, a basi fere ad apicem 
usque sulcato-canaliculata. 
Flores dioici: 2 ramulo brevissimo, cum perianthio folium caulinum vix 
aquilongo, terminales, innovatione minuta suffulti. Bracteé foliis 
4-plo minores obcordato-bilobee, lobis complicatis subeequalibus, vel 
postico subminore ligulatoque; bracteola tenera angusta ligulato- 
cuneata apice truncato obtuse 3-dentata. 
Perianthia parva obovato-cuneata rotundata retusave brevirostria valde 
compressa, Margine supra medium inciso-ciliata, aliis ciliis seepe pre- 
longis hamatis, facie posticé convexuld carinis 2 valde approximatis 
cito in unam obtusam confluentibus, pauciciliatis, percursa. Calyptra 
perianthio 4 brevior obovata, infra medium 2 ¢. crassa, apice irregu- 
lariter rupta. 
Andreecia subjulacea ramulis micro-polyphyllis constantia, rarius rami 
apicem solum tenentia. Bracteze cymbiformi-concave ultra 4 bilobee, 
lobis semiovatis (margine externo subrecto) antico rotundato, postico 
vix minore obtuso. 
Obs. Folia, e margine infero recurvo, supero incurvo, tota fere longi- 
tudine equilata videntur, sive ligulata et subfalcata. Cellule foliorum 
subplane, bractearum @ et 2 distincte convexo-prominule, perianthii 
trigonis pulchre pellucidis. - 
sractea interna major est quam externa, basique innovationi perbrevi, 
foliis parvis bijugis preeditee, adnata est. 
Forsan eadem species erit ac L. granulata, Nees in Mart. Fl. Bras. I., 
p. 852; Syn. Hep. 311; quum tamen nihil dixerunt cl. auctores de 
foliorum marginis postici recurvatione insigni, nec de perianthii ciliis 
posticis, ad illam referre non ausim. Florescentiam hujus sectionis sub 
silentio omnes auctores relinquunt.
