Description
editAll 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
editThe 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]
