Adelonema picturatum (Linden & André ex André) S.Y.Wong & Croat, 2016 - Araceae
Climbing plant with large heart shaped leaves around 24" long, 15" wide, many leaves with elongated holes or deep dentition. Climbs and smothers poles, trees. Also grows in thick clumps on ground, up to 2.5 m tall. Seen all over the Big Island of Hawai'i. No flowers observed. I'm curious for identification!
