Description

Plants in the genus Phebalium are shrubs or small trees that are often more or less covered with scales or shield-shaped or star-shaped hairs, at least when young. The leaves are arranged alternately along the stems, and are simple, sometimes with toothed edges. The flowers are bisexual and have five sepals, five petals and ten stamens. The sepals are fused at the base, usually with five lobes, and the stamens are free from each other. There are five carpels with the styles fused and the stigma is similar to the rest of the style. The fruit is a follicle and the seeds are released explosively.[2][3][4][5]

Taxonomy

The genus Phebalium was first formally described in 1805 by Étienne Pierre Ventenat in his book Jardin de la Malmaison.[6] The first species described was Phebalium squamulosum.[7]
