Vallaris

Vallaris is a genus of flowering plants belonging to the family Apocynaceae. These plants are typically woody climbers or shrubs native to tropical and subtropical regions of Asia, Southeast Asia, and Australia.

Description

Vallaris species are characterized by their opposite leaves and fragrant, often white or cream-colored, flowers. The flowers are typically tubular or funnel-shaped and arranged in cymes or panicles. They produce follicle fruits containing seeds with a coma (tuft of hairs) at one end, which aids in wind dispersal.

Classification

Vallaris is classified within the subfamily Apocynoideae of the Apocynaceae family. The genus includes several species, though taxonomic classifications can sometimes vary.

Ecology and Uses

Vallaris species are often found growing in forests, along roadsides, and in disturbed areas. Some species are cultivated for their ornamental value, particularly their fragrant flowers. Some species have also been used in traditional medicine in certain regions, although scientific validation of these uses may be limited. The milky sap produced by some Vallaris species can be irritating to the skin.
