Diagnostic Description

This species is closest to Philodendron linnaei, differing principally in the leaf blade, displaying differentiated primary lateral veins, and by the colour of the spathe, displaying wine-colouration on both surfaces. Philodendron linnaei does not show distinct primary lateral veins, but rather has fine parallel veins when dry and a red spathe tube with the inner surface of the blade white.

Habitat

Plant found on a dead tree in the forest interior or at over 10 m high in "mata de baixio" and "floresta de platô".

Distribution

Brazil (Amazonas, Bahia, Pará, Roraima), Colombia, French Guiana, Guyana, Surinam and Venezuela.
