Beilschmiedia glauca S.K.Lee & L.F.Lau in Lee (1963) 193; Hô (1991) 474; Kochummen (1989) 119;I.M. Turner (1995) 276; Tetsana (2005) 37; X.Li et al. (2008) 240;Sach. Nishida (2008) 356. — Beilschmiedia glauca S.K.Lee var. glauca . — Type: Hainan Expedition 676 (holotype HSNU not seen; isotype PE [00188583]), China, Hainan, Peisha Hsien, Yingge.

Beilschmiedia endiandrifolia Kosterm.(1957b) 38 (nom.invalid.));(1964) 125; J.A.R. Anderson (1980) 221;Sach. Nishida (2008) 357.Based on Henderson 23561 (KEP, SING), Peninsular Malaysia, Pahang, Cameron Highlands.

Trees 6–23 m tall, dbh 15–30 cm; bark reddish to grey brown, smooth to shallowly fissured; inner bark dark red with orange flecks; sapwood white. Twigs slender, 1.5–3.8 mm diam, flattened in cross-section, glabrous; terminal leaf buds lanceolate, 7.6–12.6 mm long, glabrous. Leaves alternate to (sub)opposite, blades broadly elliptic to almost rounded, 6–15 by 2.8–9.6 cm, shiny, thick to thinly leathery; apex rounded to acute, often with a distinct short tip; base rounded or broadly cuneate, sometimes asymmetric; margins flat; secondary veins 4–8 pairs, tertiary veins areolate-reticulate to scalariform; upper surface glabrous, midrib raised to flattened, secondary veins raised, tertiary veins distinct; lower surface glabrous, glaucous to very grey, midrib raised, secondary veins raised, tertiary veins distinct. Petiole 12–27 mm long, channelled, glabrous. Inflorescence 50–120 mm long, glabrous, yellow green, not enclosed at base by bracts; bracteoles linear, c. 0.4 mm long, caducous. Flowers white to greenish yellow; perianth tube not distinct; perianth lobes orbicular to elliptic, 1.2–1.7 by 1.3–1.7 mm, glabrous outside, apices rounded to acute, margins not ciliate, lobes almost equal or inner three slightly smaller. Stamens (6–)9, 1–1.5 mm long, filaments almost as long as anthers, pubescent or rarely glabrous; anthers glabrous, obtuse at apex. Staminodes 3(–6). Ovary 0.8–2 mm diam, glabrous; style 0.8–1 mm long. Fruit (dried) ellipsoid, 2.5–4.5 by 1.5–2.5 mm, apex rounded, base tapered, surface smooth, brownish, smell resinous. Stalk swollen when mature to c. 3 mm diam, not constricted at apex.

Local name — Selepak (Sakai language).

Distribution — South China to Peninsular Malaysia and Borneo, also reported from North Sumatra ( Nishida 2008: 357).

Ecology — Lowlands and montane forest, sometimes over sandstone, from 360–1375 m altitude.

IUCN Conservation Assessment — Least Concern.

Phenology — Flowering: March to September; fruiting: July to September.

Notes — The name Beilschmiedia endiandrifolia was proposed by Kostermans (1957b) to reflect the fact that the venation pattern is very similar to that seen in the genus Endiandra , since both have areolate reticulations. However, Kostermans’s name was never validly published although it does occur in the literature.

The Malaysian material of this species belongs to the type variety, Beilschmiedia glauca var. glauca , as the axillary inflorescence is glabrous (see Li et al. 2008a: 240).
