It occurs in the Sepik River basin, in wet lowland forest in modestly seasonally flooded areas. It has erect stems up to 2.5 m tall. The leaf leaves are hairy and orange at first, soon losing the hair and becoming glossy bright green, numerous and spreading, 1.8 2.5 m long. The Petiole botany petiole is armed with spines nearly over its entirety, with glabrous , glossy green leaflets angled forward about 70 80 degrees. The female strobilus cones are open, grey with orange hairs, with each sporophyll containing 6 8 ovules. The male cones are orange, narrowly ovoid. The name derives from the plant s vernacular name in the language of the Kaka tribe of the Sepik River estuary in New Guinea. First described in 1994, the plants were previously thought to be a population of Cycascircinalis . It is closely related to Cycas rumphii , with which it shares much of its geographical range. This species is not presently considered threatened, with a large population, fast growth, and remote habitat.
