STAMINATE FLOWERS with sepals 1.7-2.1 x 1.6-2 mm, concave, keeled and proximally gibbous, elliptic, rounded, entire; petals on a 1.2-1.5 mm high receptacle, 3.2- 3.5 x 1.8-2.3 mm, elliptic, fleshy, acute; stamens 6, very slightly biseriate, with the antepetalous stamens inserted slightly higher than the antesepalous ones, filaments 2.4-3 mm the abaxial midrib, and lines of scattered minute reddish scales present on the fainter veins, main vein 1, very prominent adaxially, as well as thickened margins, apex unequal, bifid in median leaflets. INFLORESCENCE interfoliar, 125-178 x 120 cm, widely spreading, branched to 3 orders; peduncle 50-58 cm long, with scattered scales, proximally c. 5 x 3 cm diam., distally c. 3.5 x 2 cm diam.; prophyll 25-63 cm long, borne at 8-12 cm above the base of the peduncle, long, thin, anthers 1.7-2 x 1 mm, dorsifixed, versatile, held horizontally at anthesis, the locules parallel and obtuse; pistillode cylindrical, c. 1.6 mm high and 1 mm diam. PISTILLATE FLOWERS unknown, but from fruiting material sepals 2.4-2.8 x 2.6-3.3 mm, broadly ovate with a small apiculum; petals c. 3.3 x 4.3 mm, with broad membranous wings and a small fleshy triangular apex; staminodes c. 1 mm high. FRUIT ovoid, later subglobose, 15-22 x 12-19 mm, with rounded apex; mesocarp fleshy-fibrous, endocarp fibrouswith anastomosing fibres. SEED subglobose to ellipsoid, 17-19 x 15-17 mm, slightly asymmetric with an apiculate base (1 mm), with shallow anastomosing grooves over its surface, with rounded apex, and an equatorial depression corresponding to the embryo; endosperm ruminate, with ruminations up to 6 mm deep.
    Vernacular
    Laafa (Ranopiso).
    Biology
    Dry forest or bush on stony soil, mid slope; 80-600 m. NATURAL HISTORY. J. Ratsirarson (pers. comm.) has observed both Black Parrot and Lemur catta feeding on the fruit mesocarp; he also found pig droppings full of seed of D. decaryi; he observed bees and flies visiting the flowers at anthesis.
    Conservation
    Vulnerable. Only known from a small area, where nearly all seed is harvested for export; fires are a threat. Population estimated at a thousand. This species is listed on CITES Annexe II.
