Description

Henonia scoparia is a shrub or small tree which grows from 1 to 2.5 meters tall. Flowers appear in March, and it fruits starting in November.[1]

Range and habitat

Henonia scoparia is endemic to southwestern Madagascar, in former Toliara Province. It is known from four herbarium specimens, with three known locations. Based on these collections, the species' estimated extent of occurrence (EOO) is 7,150 km2, and its area of occupancy (AOO) is 16 km2.[1]

It is found in dry forest, bushland, dunes, and thickets in the Madagascar succulent woodlands and Madagascar spiny thickets ecoregions, between 100 and 520 meters elevation.[1]

Little is known about the population size of the species. The species' native habitat is threatened with degradation by human activity.[1]

Name

The genus name of Henonia is in honour of Jacques-Louis Hénon (1802–1872), a French republican politician.[4] The Latin specific epithet of scoparia refers to broom, from scopae.[5] It was first described and published in (A.P.de Candolle), Prodr. Vol.13 (Issue 2) on page 237 in 1849.[3]
