Description

Plants in the genus Platysace are woody perennial herbs, shrubs or subshrubs and have simple or lobed leaves. The flowers are borne on the ends of branches in a compound umbel with small bracts and bracteoles but that sometimes fall off as the flowers open. The flowers are bisexual or male, sometimes without sepals, and have white, cream-coloured or pinkish, elliptical to egg-shaped petals. The fruit has 2 compressed mericarps. [2] [3] [4] [5]

Taxonomy

The genus Platysace was first described in 1845 by Alexander von Bunge in Lehmann's Plantae Preissianae , and the first species he described (the type species) was Platysace cirrosa . [6] [7]

A 2021 molecular phylogenetic study suggested that it is sister to rest of the family Apiaceae, and so does not belong to any of the four subfamilies into which the family is divided. It has been suggested that it could be placed in a subfamily of its own. [8]
