DISTRIBUTION AND ECOLOGY

Calantica biseriata is native to forests of western to northern Madagascar, often bordering rivers or streams, on limestone.

REMARKS

Calantica biseriata is a tree to 20 m, sometimes multi-trunked, with finely fissured bark. The petals are reddish or reddish-green, while the sepals may be green; the glands and anthers are (at least sometimes) yellowish and the filaments reddish.

Ethnobotany

The semi-soft wood of Calantica biseriata is used for construction (Service Forestier 19033).

Vernacular names

Hazoambo (Labat & Deroin 2294); Hazofoty (Leandri 548).

CONSERVATION STATUS

The preliminary assessment of the conservation status of Calantica biseriata is Vulnerable (VU B2ab(iii)). Although the Extent of Occurrence is 91 262 km 2, the Area of Occupancy is estimated to be less than 2000 km 2, and fewer than ten locations are known; remaining natural vegetation in most of the known range is experiencing anthropogenic decline in area and quality. It is present in two protected areas, Bemaraha and Namoroka.
