Cycas arnhemica

A cycad from Arnhem Land with stems 1.5–2.5 m tall, confined to the Goyder and lower Blyth river areas of the Northern Territory. It grows in fire-prone eucalypt woodland and savanna with a monsoonal wet season and a long, hot dry season, so it wants heat, sun and a very well-drained soil.
