grandiolia adest juxta Obidos et ad fl. Caipuraé, lobulo margine supero 
rotundato, apice in supremis foliis apiculato-acuto, in inferioribus autem 
solum abrupte acuto vel etiam rotundato.—Altera forma, e fl. Uaupes, 
foliola hic majora lobulos obvelantia, illic per intervalla minora lobulorum 
apices haud attingentia, habet. Ad Manaos fl. Negro advenit forma 
pusilla, lobulis seepe diminutis, foliolis magnitudine variis; altera ad 
Para, in Mastigobryo repens, elongata, foliolis minoribus, lobulos raro 
obtegentibus.—Forme insigniores sunt : 
Var. intermedia, floribunda. Lobulus dimidium folium fere zequans 
foliolis parvulis raro obvelatus, acutus nec apiculatus. Perianthia postice 
distincte bicarinata, carinis approximatis inferne ol)tusis—quasi in unicam 
latam confluentibus—solum apicem versus magis argutis; margine plus 
minus scaberula, interdum grosse subserrata.—Cuript, prope Pard, in cortice. 
Var. unicarinata. Lobulus parvus, folio 4-5-plo brevior, acutus. Peri- 
anthia magis compressa, apice rotundata vel obcordata, carinis posticis 
parum prominulis sepissime in unicam obtusam coalitis, margine sub- 
leevissima.—Pard, in cortice.

matricem horizontaliter patuli, ramosi, substratificati, ramis confertis 
iteratim proliferis monotropis. 
Folia dense (ultra $ lat.) imbricata, semicordato-ovato-oblonga, sublingue- 
formia, apice decurvo obtusata—raro subacuta rotundatave, margine 
antico late recurva, postico subrecte complicata ; lobulus magnus =

ovato-rhomboideus apiculato-acutus, minime foliolo proximo obve- 
latus sed ultra ejus orbem longe protensus; cellule subparvule

Foliola dimidio folio subeequilonga late cuneato-orbiculata-reniformiave 
recurvo-convexa, ad basin profunde foveolata—nec longe canaliculata

Flores dioici: 9 terminales, innovatione prolifera suffulti. Bracteze foliis

Perianthia subimmersa, cuneato-pyriformia, compressula retusa subrostel-
