3. Beilschmiedia moratii van der Werff  

Novon 6: 463 (1996). — Type: Service Forestier (Capuron) 24985, Madagascar, massif de Tsaratanana (holo-, MO!; iso-, P, n.v.)   .

Shrubs or trees, to 15 m tall. Twigs terete, glabrous, the young ones black, older ones with grey, corky bark. Terminal bud glabrous. Leaves subopposite, coriaceous, 2.5-4 × 1.5-3 cm, broadly elliptic, shiny, base and apex obtuse to rounded, the margin often incurved, glabrous, lateral veins 4-7 on each side, poorly differentiated from the tertiary venation, midrib weakly raised on both surfaces, lateral veins and reticulation prominently raised. Petioles 4-7 mm long, glabrous. Inflorescences axillary, paniculate, to 2.5 cm long, puberulous, the hairs curled, more or less erect, base of the flower often with a glabrous bract with ciliate margin, this c. 2 mm long. Flowers depressed globose, 3-4 mm wide, reddish green. Tepals 6, equal, broadly elliptic to ovate, the margin thinner than the center, outside sparsely puberulous, inside glabrous, the bases fused, tepals deciduous in old flowers and leaving a circular scar at the base of the very young fruit. Stamens 9, 2-celled, the outer 6 broadly ovate, c. 2 mm long, pubescent along margin, cells large, introrse, filament very short; inner 3 narrowly triangular, densely pubescent, 1.5-2 mm long, cells lateral, 2 large globose glands present at base of filaments; staminodia of Whorl IV small, triangular, pubescent; bases of filaments of Whorls III and IV fused into a narrow, pubescent ring. Pistil glabrous, ovary turbinate, gradually narrowed into the short style. Fruit obovoid or roundish, 4.5 × 3.5 cm, a little warty.




ECOLOGY. — Forest at mid and high elevation (1300-2100 m).

PHENOLOGY. — Flowers in November.

Beilschmiedia moratii   is closely related to B. opposita   and B. sary   ; these species are characterized by their subopposite leaves, black young twigs, dehiscent tepals in old flowers and their (nearly) glabrous condition. Beilschmiedia moratii   differs from both species in its obtuse to rounded leaf bases and the sparse, erect hairs on the inflorescences; from B. opposita   it also differs in its raised reticulation and from B. sary   in its smaller leaves.

COMMON NAMES. — Maitsoravina, Voantsilana.
