Description
Plants in the genus Bertya are usually monoecious, often sticky shrubs, either glabrous or covered with woolly, star-shaped hairs. The leaves are usually arranged alternately, simple, sessile or on a short petiole, flat or with the ends curved downwards, and lack stipules. The flowers are sessile or on a short pedicel, usually singly, or in umbel-like clusters on a peduncle in leaf axils. Male flowers usually have no petals, but many stamens with their bases fused, and no styles. Female flowers are small and narrower, have no petals, the ovary usually with three locules and three styles fused at the base. The fruit is a capsule, usually containing a single oval, elliptic or oblong seed with a creamy-white to yellowish caruncle.[2][3][4][5]
Taxonomy
The genus Bertya was first described in 1845 by Jules Émile Planchon in William Jackson Hooker's London Journal of Botany.[6][7] The name of the genus (Bertya) honours the French botanist and horticulturist Count Léonce de Lambertye.[2]
