Cycas basaltica is a species of cycad in the genus Cycas, native to Australia, in the far north of Western Australia in the Kimberley region. The stems grow to 2 m (rarely 4 m) tall and 15-23 cm in diameter, with a swollen base and an enlarged subterranean structure. There are 30 or more leaves in the crown, forming a bowl shaped, inward facing leaf crown, each leaf 80-125 cm long, pinnate, with 140-210 leaflets. Younger plants have spiny petioles, with older specimens losing this trait. The leaflets are covered with a dense layer of silver hairs, angled forward at 70-80°. The basal leaflets are reduced to spines, similar to Cycas revoluta. The taproot is contractile, and tends to pull crown downwards.
