Cycas campestris is a species of cycad in the genus Cycas, native to southeastern Papua New Guinea in the lowland region near Port Moresby. It grows in open, grassy locations, often in areas with frequent grass fires.
The stems are erect, up to 2.5 m tall and 20 cm diameter. The leaves are orange tomentose on emerging, soon becoming bright glossy green and glabrous, 80âÂÂ170 cm long, pinnate, with 120-230 leaflets. The leaflets are 8.5âÂÂ16 cm long and 5âÂÂ8 mm wide, and lie flat or in a shallow 'v'-shape on either side of the leaf stem. The leaf petioles are 15âÂÂ90 cm long, and armed with sharp spines at the base.
The female cones are open, with sporophylls 13âÂÂ25 cm long, with two to six ovules per sporophyll. The lamina is lanceolate, with spined dentate margins and an apical spine. The sarcotesta is 2âÂÂ3.5 mm thick and orange, the sclerotesta flattened and long ovoid, with a network of shallow grooves. The male cones are solitary, narrow ovoid, 13âÂÂ17 cm long and 7âÂÂ9 cm diameter, brown, the sporophylls 33âÂÂ40 mm long with an apical spine.
