Known only from a single site where the area of occupancy and extent of occurrence are estimated to be well less than 4 km² (even less than 1 km²) and is threatened by increased fire frequency and grazing which may reduce the quality of the habitat for the population and any regeneration. About 30 mature trees have been counted at this site. The species is listed as Critically Endangered.
|Range Description:||This species is known only from a single locality in Analalava district, in the northwest of Madagascar.|

|Population:||About 30 mature individuals are known in the wild. The current population trend is unknown as this species was only discovered fairly recently. It was almost certainly commoner in the past, as much of the habitat where it occurs has been converted to agricultural lands.|
|Habitat and Ecology:||Occurs in the gently rolling hills and flatlands of the region, now dominated by anthropogenic grasslands, there is a small outcrop of 'tsingy', karst Tertiary limestone, about 250 m long, carrying a semi-natural vegetation. Tahina grows in seasonally flooded land at the foot of the limestone hill at an elevation between 10 and 20 m|
|Major Threat(s):||The increased frequency of fire is probably the main threat at present, as most of the former habitat has been transformed. Grazing by livestock also poses a threat to the remaining habitat and to the regeneration of this species.|
|Conservation Actions:||Efforts are under way to conserve this species through distribution of seed and cultivation in botanic gardens. The site is not formally protected. Regular monitoring of the population is required.|
