Lysiosepalum is a genus of 5 species of flowering plants in the genus of plants in the family Malvaceae, all endemic to the south-west of Western Australia.
All species of Lysiosepalum are shrubs up to 1.5 m (4 ft 11 in) high. The leaves are mostly linear to egg-shaped with 2 leaf-like stipules at the base of the petiole. There are petal-like sepals alternating between broad to narrow, and tiny, scale-like petals. Three egg-shaped or lance-shaped bracteoles are below the sepals, bracts at the base of the pedicels, the stamens are joined at the base and there are tiny staminodes. [2] [3] [4]
The genus Lysiosepalum was first formally described in 1858 by Ferdinand von Mueller in his Fragmenta Phytographiae Australiae , and the first species he described (the type species) was Lysiosepalum barryanum . [5] [6] The genus name means a "setting-free sepal", referring to the sepals, which are almost free or separated. [2] [7]
The following is a list of names of Lysiosepalum species accepted by the Australian Plant Census as at April 2022: [8]
Species of Lysiosepalum occur in open woodland or shrubland between Yuna and Ravensthorpe in the south-west of Western Australia. [3] [4]
