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.
Description
[edit]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]
Taxonomy
[edit]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]
Species list
[edit]The following is a list of names of Lysiosepalum species accepted by the Australian Plant Census as at April 2022:[8]
- Lysiosepalum abollatum C.F.Wilkins - woolly lysiosepalum
- Lysiosepalum aromaticum C.F.Wilkins
- Lysiosepalum hexandrum (S.Moore) S.Moore
- Lysiosepalum involucratum (Turcz.) Druce
- Lysiosepalum rugosum Benth. - wrinkled-leaf lysiosepalum
Distribution and habitat
[edit]Species of Lysiosepalum occur in open woodland or shrubland between Yuna and Ravensthorpe in the south-west of Western Australia.[3][4]
