Distribution

Known from southern Venezuela (Amazonas) and southern Colombia (Vaupes) at 100-800 m. In Venezuela, it is known only from the Department of Atabapo at Cucurital de Caname and in the Serranfa Yutaje on the Río Manapiare.

Uses

The leaves and petioles of Philodendron craspedodromum are reputed by the Desano Indians of the Rio Papuri to be toxic to fish when crushed and cast into stagnant waters. When used for fish-poisoning, the leaves are cut, tied into small bundles and set on the forest floor for one or two days to "steam" and start fermentation and rotting before being crushed for use.
