Description

The chromosome count is 2n = 18.

Species

ImageScientific nameDistribution
Bowenia serrulata Chamb.Queensland
Bowenia spectabilis HookQueensland

Distribution

The two living species occur in Queensland. B. spectabilis grows in warm, wet, tropical rainforests, on protected slopes and near streams, primarily in the lowlands of the Wet Tropics Bioregion. However, it has a local form with serrate pinna margins that grows in rainforest, Acacia-dominated transition forest, and also Casuarina-dominated sclerophyll forest on the Atherton Tableland, where it is subject to periodic bushfire. B. serrulata grows in sclerophyll forest and transition forest close to the Tropic of Capricorn.

Fossils

The fossil species Bowenia eocenica is known from deposits in a coal mine in Victoria, Australia, and B. papillosa is known from deposits in New South Wales. Both fossils are of Eocene age, and consist of leaflet fragments.
