The Malayan sword (Aglaonema simplex) belongs to Araceae (the Arum family). It is a perennial herb that is distributed in Malaysia, Burma, and Borneo. The rhizomes crawl and spread, reaching 30-40 cm in height. The leaves are broadly elliptic with long petioles and are reddish when young, becoming dark green as they grow. It produces white flowers surrounded by pale greenish-white spathe bracts. Horticulturally, it is called "Ryoku-chiku" (green bamboo) in Japan and is treated as an aquatic plant.
