Cycas bifida (syn. Cycas rumphii var. bifida) is a species of cycad plant in the genus Cycas, native to southern China (southern Guangxi and eastern Yunnan), and northern Vietnam (Cao Bằng, Lạng Sơn and Tuyên Quang provinces). The species is named after its dichotomously divided leaflets, a character shared with a few other related species. It has been extensively confused in literature with the related species and Cycas micholitzii (K. D. Hill, Cycad Pages); in the Flora of China, it is treated as Cycas micholitzii, a species restricted by Hill to plants from central Vietnam and Laos.

  • Cycas bifida (syn. Cycas rumphii var. bifida) is a species of cycad plant in the genus Cycas, native to southern China (southern Guangxi and eastern Yunnan), and northern Vietnam (Cao Bằng, Lạng Sơn and Tuyên Quang provinces). The stems are largely subterranean, 20–60 cm in diameter and up to 20 cm above ground level, and bear three to eight leaves. The leaves are 2–4 m long and 40–80 cm broad, dark green and glossy, bipinnate, with 27-44 pairs of leaflets, each leaflet dichotomously divided (split in two), linear, 10–38 cm long and 1.5–3 cm broad, papery to leathery in texture; the leaf petiole is 0.5–2 m long, armed with spikes. The female cones are closed, the sporophylls 8–12 cm long, with deep red-brown tomentose down, and 6-8 ovules on an ovate lamina, with yellow to yellow-brown sarcotesta. Ovoid and flattened sclerotesta. The male cones are solitary and erect, spindle shaped and cylindrical 15-23 long and 4–6 cm broad, with light yellow tomentose down and an erect apical spine with 1.2–2 cm sporophylls with 1-3 minute teeth per side. The species is named after its dichotomously divided leaflets, a character shared with a few other related species. It has been extensively confused in literature with the related species and Cycas micholitzii (K. D. Hill, Cycad Pages); in the Flora of China, it is treated as Cycas micholitzii, a species restricted by Hill to plants from central Vietnam and Laos. , which is often considered synonymous with Cycas bifida but may have hybridized with Cycas multipinnata, is only found in cultivation in Jinping County, Yunnan.
