DISTRIBUTION AND ECOLOGY. — Canarium globosum , sp. nov. is one of the more broadly distributed species of the genus in Madagascar, known from Fort-Dauphin in the south to Vohémar in the North, occurring in littoral forest, dry forest, and humid forest, 0-500 m elevation. Flowering Jan., fruiting throughout the year.

ETYMOLOGY. — The specific epithet refers to the globose fruit shape. COMMON NAMES AND USES. — Tsiramiramy; ramy mena, ramytsitsihy, sandramy.

The resin is used to kill mites on the feathers and skin of chickens (famonoana tsingongotran’akoho), also used for caulking canoes, illumination, and religious (tromba) ceremonies.

Staminate inflorescences 17-30 cm long, secondary axes to 12 cm long, axes with dense ferrugineous capitate glands, also sparse to dense flexuous ferrugineous hairs to 0.2 mm long; subglabrescent in fruit; bracts 1.5- 1.6 mm long, apex acute, shorter than the buds, with thick ascending ferrugineous hairs to 0.05 mm long; bracteoles c. 1.2 mm long, lanceolate to subulate, shorter than mature buds; pedicel c. 2.5 × 0.5 mm, with dense ferrugineous capitate glands, also sparse flexuous ferrugineous hairs to 0.2 mm long. Staminate buds (mature) 3.3-3.4 mm long; calyx 1.4-1.5 × 2.6-2.7 mm overall, taller than ovariodisk, cupular, cream-colored, the lobes 0.4-0.5 mm long, rounded depressed-deltate, pubescence as on inflorescence but denser; petals 3.3-3.4 × 1.5-1.7 mm, exposed part longer than calyx, oblong, apex obtuse with an inflexed apiculum 0.3-0.4 mm long, fleshy, abaxial surface with dense retrorse whitish hairs to 0.1 mm long; stamens inserted at base of ovariodisk, the antesepalous stamens 2.6 mm long with anthers 1.4 mm long, the antepetalous stamens 2.2 mm long with anthers 1.2 mm long, the anthers oblong-lanceolate in dorsiventral view, oblong in lateral view, with apiculate connective; ovariodisk 0.25-0.45 mm tall, 0.8-1.1 mm thick, discoid, apex craggy. Pistillate inflorescences to 11.5 cm long, secondary axes to 5 cm long; 3.6-5.7 cm × 0.9-1.3 mm diam. Pistillate flowers 5.6-6.2 mm long; calyx 2.8-4.5 × 3.2-4.4 mm overall, reaching the base of stigma, slightly urceolate, fleshy, lobes 0.6-1 mm long, depressed-deltate, abaxial surface with dense erect to ascending golden to ferrugineous hairs to 0.2 mm long; petals 4.6 × 1.4 mm, exposed part of corolla shorter than calyx, narrowly obovate, apex obtuse, slightly spread- ing, abaxial surface with dense ascending pale golden hairs to 0.15 mm long; staminodes inserted on rim of a shallow hypanthium, 2-2.3 mm long, anthers 1-1.3 mm long, lanceolate; pistil 3-3.3 × 1 mm, the ovary narrowly ovoid and substipitate, style 0.7-1.1 mm long, stigmatal area 0.6-08 mm long, capitate. Fruiting pedicel 4-9 × 2.5-3.6 mm, cylindrical to slightly clavate, fruiting calyx 2-3 mm long, spreading to patent, lobes not distinct, abaxial surface with scattered round raised lenticels, adaxial surface with dense appressed golden hairs to 0.1 mm long. Fruits 2-3.8 × 2-2.5 cm, subglobose to (ob)ovoid, sometime broadly so, surface smooth and usually glossy (appearing foveolate under 40 × magnification), green to brown or dark brownish violet, glabrescent, mesocarp thin (dries only slightly wrinkled).
