Leptolaena cuspidata

Leptolaena cuspidata is a shrub to a small tree. It flowers from January to November.[1]

Leptolaena cuspidata is endemic to northwestern Madagascar. It inhabits dry deciduous forests of central Diana Region, and the subhumid forests of the Sambirano region in southern Diana Region and northernmost Sofia Region. It grows from 10 to 500 meters elevation on a variety of substrates, including sandstone, lava, basement rock, Mesozoic limestone, unconsolidated sands, and alluvial and lake deposits. The species is known from 129 records at 21 locations. Based on the known locations, the species' estimated extent of occurrence (EOO) is 24,265 km², and an estimated area of occupancy (AOO) of 252 km². These estimates may be low because of under-sampling.[1]

The species has a declining population, and is threatened by habitat loss across much of its range. Threats include deforestation from shifting cultivation and logging, over-harvesting timber, and the declining population of animals, including birds and lemurs, which disperse its seeds.[1]
