7. Beilschmiedia sary Kosterm.  

Commun. Forest Res. Inst. 56: 6 (1957). — Type: Service Forestier (Capuron) 8758, Madagascar, piste Maroantsetra-Antalaha (holo-, P!)   .

Large tree, to 25 m tall. Twigs glabrous, terete, the young ones smooth, black, older ones greycorky. Terminal buds glabrous or nearly so. Leaves subopposite, coriaceous, 8-12 × 3-5 cm, glabrous, elliptic or elliptic-obovate, tip obtuse or emarginate, base acute or cuneate, lateral veins weakly developed, 7-12 on each side, poorly differentiated from the tertiary venation; midrib immersed on upper surface, raised on lower surfaces; lateral veins and tertiary venation raised on both surfaces. Petioles glabrous, 6-10 mm long. Inflorescences axillary, glabrous, to 1.5 cm long, racemose, rarely paniculate, 5-7 flowered. Flowers glabrous, with a short funnel-shaped floral tube, the tepals erect to incurved, often with a glabrous bract at the base of the floral tube. Tepals 6, equal erect or incurved, ovate, c. 1.5 mm long. Stamens 6, representing the outer 2 whorls, pubescent, 2-celled, the filament very short, anther large with large locelli, c. 1 mm long; Whorl III represented by 3 stamens with rudimentary(?) locelli and 2 globose glands at the base; staminodia representing Whorl IV not seen. Receptacle broad, shallow, densely pubescent. Ovary globose, glabrous, well differentiated from the glabrous style. Fruit broadly ellipsoid, 3 × 2 cm, tepals and receptacle dehiscent in older flowers and leaving a circular scar at base of young fruit.

ECOLOGY. — Forest at low elevation (100- 500 m).

DISTRIBUTION. — Most collections are from the area around the Baie d'Antongil; one sterile collection provisionally placed here is from Andilanatoby, much further south. — Fig. 3. View Fig

PHENOLOGY. — Flowers in September; fruits in December.

Beilschmiedia sary   is similar to B. opposita   , but is larger and coarser, growing at lower elevation and with a noticeably raised reticulate venation on both leaf surfaces. The inflorescences are as small as in B. opposita   ; the flowers of B. sary   seem to lack staminodia representing Whorl IV, while the stamens of Whorl III are poorly developed and likely sterile. However, only one flowering specimen with few flowers is known. The tepals are deciduous in older flowers exactly as in B. opposita   .
