Alocasia robusta is a gigantic herb of the arum family (Araceae) which is endemic to the island of Borneo. The plant is a rosette herb consisting of several very large leaves having a sagittate (arrowhead shaped) lamina or blade up to 12feet long by 8feet wide, borne on very stout petioles or stalks up to 12abbr=offNaNabbr=off in length. More recently, Anthony Lamb of the Sabah Agricultural Department found and measured one individual with a lamina 15feet in length.,[1] the largest leaf of any non-palm (Not belonging to the family Arecaceae). The inflorescence is the spathe and spadix typical of the Arum family, with the spathe being a very dark blackish-purple color. This species was unknown to science prior to 1967.[2] [3] The plant is usually trunkless.
