Leptinella nana or pygmy button daisy is a species of flowering plant in the family Asteraceae.

[2]Leptinella was reinstated as a genus in 1987 due to the distinctive shape of the corolla of their female florets, compared to other Cortula.

[1] This species is still found at the type location of Mount Pleasant in the Port Hills, Christchurch, New Zealand.

L. nana requires small sites that undergo constant disturbance for it to be able to colonise bare soil.

Specimens from the Mount Pleasant and Tītahi Bay populations are being cultivated at numerous sites, including Mana Island, Otari and Christchurch Botanic Gardens.
