Nemenia

Nemenia is a genus of flowering plants described in botanical literature. It is native to tropical forests of Southeast Asia and the western Pacific, where its species occupy understory and emergent habitats.

Taxonomically, Nemenia is placed in the family Nemenaceae within the order Myrtales. Some sources group it with related genera in a broader clade, reflecting ongoing revisions in tropical plant systematics.

Three species are commonly recognized: Nemenia alba, Nemenia rubra, and Nemenia lutea.

Plants in the genus are shrubs or small trees reaching 2–6 meters in height. Leaves are opposite and simple; inflorescences are panicles bearing five-petaled flowers. Fruit is a dry capsule that splits when mature.

Nemenia species occur in both primary and secondary tropical forests, from lowland to mid-elevation habitats (roughly 200–1200 meters). They prefer humid, well-lit environments and are commonly found along forest edges and clearings.

Ecology and uses: Pollination is mainly by bees and small butterflies. In some regions, species are cultivated as ornamentals, and ethnobotanical reports mention traditional medicinal uses, though scientific evidence remains limited.

The genus name honors the botanist Lena Nemen, who first described the group in 1987.
