Name: Philodendron lupinum E.G.Gonç. & J.B.Carvalho
Etymology: The specific epithet lupinum is derived from the Latin word for “lupine”.
First described: 2008 by Eduardo G. Gonçalves and J. B. Carvalho.
Origin/Distribution: Brazilian Amazon.
Location/Habitat: Climbing hemiepiphyt in warm, moist terra firme forest at low altitudes. We recommend approximately 20–29 °C, high humidity, good air circulation, and bright, indirect light.
Description and notes: The species shows a pronounced transition between juvenile and adult forms. Young leaves are small, heart-shaped, and velvety with a chestnut-colored underside; mature leaves become longer and greener. A support promotes the development of the mature leaf shape. Keep coarse, airy aroid substrate evenly lightly moist and avoid waterlogging.
