Arabidella, but was elevated to genus status by Otto Eugen Schulz in 1924. The type species is Arabidella trisecta. A molecular study in 2022 redescribed the genus and differentiated it from Lemphoria, describing Arabidella species as being shrubs or subshrubs, and rarely annual herbs, and having lower leaves divided into 2-3 linear to filiform lobes; having confluent nectar glands together with median glands, having 20-90 ovules 20–90 per ovary and having linear fruits. Species in the Lemphoria genus are annual herbs whose lower leaves are essentially pinnate, with lateral nectar glands and no median glands, and having 6-70 ovules per ovary and oblong fruits. Its native range is Australia, and is found throughout the mainland ("endemic in the s......read more on Wikipedia.
