About

Philodendron crassinervium is a species of plant in the genus Philodendron native to southeast Brazil.

It has lance-shaped leaves that point upwards and can grow almost a meter long with a width of about 10 centimetres (3.9 in). The leaves have a prominent midvein that is used to store water for periods of drought that occur during the dry season. Along the midvein, there are small red glands that produce a clear sap that results in a freckled-look on both sides of the leaves. The plant has a climbing growth habit. Its aerial roots of the plant are red when they first begin growing and later turn a dark brown with age.
