Abrotanella rosulata is a plant in the family Asteraceae, endemic to the Campbell Islands.

[4] Hooker describes it[3] as "a small, densely tufted, moss-like herb", with stems that are 1–1.5 inches (2.5–3.8 cm) high.

[3] It was first described in 1844 as Ceratella rosulata by Joseph Dalton Hooker who found it in the Campbell Islands, "in crevices of rocks at the tops of the mountains, at an elevation of 1400 feet",[5] but in 1864 he amended the genus to Abrotanella.

[3] In 2009 and 2012, it was declared "At Risk - Naturally Uncommon" under the New Zealand Threat Classification System.

[6] In 2018 its status remained as "At Risk - Naturally Uncommon" due to its restricted range.
