'''''Cycas arenicola''''' is a species of [[cycad]] in the genus ''[[Cycas]]'', native to [[Australia]], in the far north of [[Northern Territory]] in the basin of the upper East Alligator River in [[Arnhem Land]]. It grows in [[Eucalyptus]] woodlands on highly [[siliceous]] soils (sandstone derived). They thrive in open situations.<br />
<br />
The stems reach 1.5 m (rarely 2.5 m) tall, with a diameter of 15-20 cm. The [[leaf|leaves]] are numerous, 0.9-1.6 m long, pinnate with 180-200 leaflets, glossy bright green above, pubescent beneath with brown pubescence, the leaflets are oriented 60-90 degrees forward without overlapping. The [[Petiole (botany)|petiole]] is brown pubescent, 25-35 cm long, armed with spines.<br />
<br />
The female [[strobilus|cones]] open, with [[sporophyll]]s 15-20 cm long, grey with orange hairs, each with 4-6 ovules. Margins toothed, with bright orange [[sarcotesta]] when ripened. The male cones are solitary, spindle shaped, 25 cm long and 9 cm diameter. <br />
<br />
The name derives from Latin ''arena'' and ''-cola'', "sand dweller", the species growing in [[sandstone]] habitats.<br />
<br />
First described in 1993 by Hill, the plant is not thought to be threatened as its range occurs on Aboriginal land and is very remote. The plant is dependent on very dry, seasonally variable conditions, and is susceptible to crown rot.<br />
