The leaves are 1.8-2.5 m long, and pinnate, with 100-150 leaflets and several basal spines; they are glossy dark green, but covered in orange pubescence at first which soon wears off. The leaflets are 35-52 cm long and 13-19 mm wide, and the basal spines .<br /> <br /> The name derives from the latin aculeatus, which translates as &quot;prickly&quot;, indeed has short prominent spikes along the [[Petiole (botany)|petiole]] (the leaf stalk). The stems are usually to slightly emergent, with trunk 6 inches in diameter. Emergent leaves are bright orange, and turn dark green with age, somewhat similar to [[Zamia integrifolia]] by coincidence.<br /> <br /> The male [[strobilus|cones]] are solitary, 15-20 cm long and 4-6 cm diameter; the female cones are undescribed. <br /> <br /> ===Habitat===<br /> This cycad is one of a number of related subterranean species native to SE Asia. It is most closely related to ''[[Cycas balansae]]'', little is known about this cycad. It grows in deep [[loam]] over [[granite]] in the inner forests of Vietnam. During the [[Vietnam war]], herbicide spraying and mass bombings may have severely upset the plant's native habitat and may have killed many of the plants. <br /> <br /> ==References==<br /> *[http://plantnet.rbgsyd.nsw.gov.au/cgi-bin/cycadpg?taxname=Cycas+aculeata Cycad Pages: ''Cycas aculeata'']<br /> <br /> [[Category:Cycads]]</div>
