During a revision of Mimosa sect. Mimosa from southern Brazil, we noticed that M. adpressa Hook. & Arn., a species of M. subser. Obstrigosae (Benth.) Barneby, has never been typified and that M. subinermis Benth. has long been considered a synonym of M. rupestris Benth. We designate here a specimen from Argentina, collected by Tweedie and deposited in the Kew herbarium, as the lectotype of M. adpressa. Furthermore, we show that M. subinermis is readily distinguished from M. rupestris by many morphological features (e.g. habit, calyx type, fruits), supporting our hypothesis that M. subinermis is a distinct species.
