Philodendron oblongum

Philodendron oblongum is a hemiepiphytic climber of the Brazilian Atlantic Forest, with ovate-oblong leaves, first described by Vellozo as Arum oblongum. Wild records range from near sea level to about 1,150 m in Espírito Santo and Rio de Janeiro. There it has warm, humid summers and noticeably cooler, drier winters. It suits a warm room with bright indirect light, a climbing support and a slightly drier, cooler winter.
