'''''Cycas angulata''''' is a species of [[cycad]] in the genus ''[[Cycas]]'', native to [[Australia]] in northeast [[Northern Territory]] (lower reaches of the [[Foelsche River|Foelsche]], [[Robinson River|Robinson]] and [[Wearyan River]]s near [[Borroloola, Northern Territory|Borroloola]]) and northwest [[Queensland]] ([[Bountiful Islands]]).
It is the largest Australian ''Cycas'' species, with arborescent and frequently branched stems growing to 5 m (rarely 12 m) tall, and 15-25 cm in diameter. Older specimens lose the leaf base scars and gain a more checkerboard appearance. The [[leaf|leaves]] are 1.1-1.7 m long, pinnate with 180-320 leaflets, the leaflets 14-23 cm long and 4.5-6.5 mm wide, grey-green to glaucous; there are to 40 leaves in the crown. The leaf petioles are armed with spines in younger individuals (a few millimetres long) with this trait being lost in older individuals.
The female [[strobilus|cones]] are open type [[sporophyll]]s 25-50 cm long, brown, each with 6-12 ovules each. The [[lamina]] is triangular ending in a sharp narrow spine. The male cones are solitary, erect, 20-25 cm long and 12-15 cm diameter.
The name derives from the Latin angulatus, which translates as "angular", referring to the leaflet arrangement on the leaf petiole.
===Cultivation===
It is occasionally grown as an [[ornamental plant]]; seeds are presently available for buyers.
