Twigs terete or slightly angled, subglabrous or minutely tomentellous to brown tomentose. Terminal bud tomentellous or brown tomentose. Leaves alternate, chartaceous, 9-20(-28) × 4-11(-20) cm, (broadly) elliptic or (broadly) ovate, the base obtuse to acute, rarely rounded, the tip acute or shortly acuminate, the upper surface glabrous or somewhat tomentose on the major veins, the lower surface sparsely tomentellous and glaucous to densely brown-tomentose, lateral veins 7-12 on each side, midrib, lateral veins and tertiary venation immersed on upper surface, midrib, and lateral veins clearly raised on lower surface, tertiary venation slightly raised. Petioles 10-25(-30) mm long, subglabrous to brown-tomentose. Inflorescences axillary, brown-tomentellous or brown-tomentose, paniculate, multiflowered, 4-10 cm long; elliptic, brown-pubescent bracts to 2.5 mm long frequently present at anthesis. Flowers with spreading tepals, to 8(-10) mm in diameter. Tepals 6, equal, brown tomentellous on both surfaces, to 4 mm long. Stamens 9, 2-celled, the outer 6, c. 0.7 mm long, glabrous, the filament short to very short, the anther with large, sometimes narrow, lateral or lateral-introrse cells; inner 3 as outer 6, more columnar, cells lateral or lateral-extrorse, with 2 globose glands at or near the base of the filament, staminodia 3, small, glabrous. Pistil glabrous or pubescent, the ovary gradually narrowed into the short style. Receptacle shallow, densely pubescent. Fruit ellipsoid to roundish, c. 3 cm in diameter, when young with persistent tepals at the base, the tepals eventually breaking off. ECOLOGY. — Montane forests, 700-1200 m . DISTRIBUTION. — Most collections come from two localities: midaltitude mountains in the NE (Anjanaharibe, Betsomanga, north to Ankarangana) and Périnet/Analamazaotra, with a single collection from Ranomafana National Park. — Fig. 2. PHENOLOGY. — Flowers and fruits year-round. Beilschmiedia velutina , as here accepted, is a very variable species and includes specimens previously placed in B. grandiflora . KOSTERMANS separated these two species on the following characters: B. velutina included material with densely pubescent leaves and a densely tomentellous pistil whereas specimens of B. grandiflora had sparsely tomentellous, glaucous leaves and a glabrous ovary. These differences would be quite adequate for the recognition of two species were there not so many intermediate specimens. Many collec- tions, both fertile and sterile, have a pubescence which is intermediate between the indument of the type specimens of B. velutina and B. grandiflora . Moreover, Service Forestier (Capuron) 27801 has a very glabrous pistil and densely pubescent leaves. One could possibly maintain B. grandiflora as distinct based solely on its glabrous pistil, but then these two species, differing in only one character, would be sympatric throughout most of their ranges. Label data do not suggest any ecological separation between the two and it would be impossible to identify sterile or fruiting specimens. Such a separation does not seem meaningful and I therefore place B. grandiflora in synonymy under B. velutina . The difference between glabrous and tomentellous pistils is nevertheless striking and appears to be correlated with spreading versus incurved tepals, although this might reflect whether the material was freshly pressed or not.
