A small clustering palm. Individual stem that produces inflorescence dies, This is a Monocarpic palm, Hight around three meters, Full sun, or light shade. Unlike the kaong, Gumayaka is a small, acaulescent (trunkless palm), with thick and adventitious roots. Stems are not long, but relatively slender and occurring in tufts or clumps. Leaves are up to 5 to 8 meters long, spreading, with petioles 1 to 2 meters long, green, channeled along the base where the edges are fringede with black, ascending bristlelike fibers. The leaflets are linear, varying from 50 to 80 cm long and 1.5 to 4 cm wide, sometimes partially united at the apex, opposite or in alternating pairs, subglaucous underneath, the constricted base with a small lobe, truncate apex finely toothed, the midrib ridged beneath.Peduncles are about 30 cm long and 2.5 cm thick. Male flowers are on separate stalks, about 1 cm long, the petals bulgiing out along valvate sides. Fruiting spikes are pendulous, longer and more numeroous than the male spikes. Fruit is globose, smooth, thin-skinned, scanty pulp, dark red when ripe, and usually two-seeded. Editing by edric.
