Blumeodendron View in CoL (?) bullatum Airy Shaw (1965) View in CoL 310;(1972a) 86; (1975) 58. — Type: Haviland & Hose 3658 (holo K; iso BM, L), Sarawak, near Kuching .

Probably trees; branchlets generally round, nodes notably thickened to side of leaf; lenticels absent or indistinct; flowering branches c. 5 mm diam. Indumentum of simple, white hairs and occasionally lepidote hairs on nodes. Leaves alternate to subopposite; petiole 0.5–1.6 cm long, diam of thinnest part 0.2–0.5 cm, round, dull, basal pulvinus 0.4–0.5 cm diam, simple hairs present; blade elliptic, 6.1–22.3 by 3.8–10.3 cm, length/width ratio 1.6–2.2, coriaceous, symmetric, strongly bullate, drying brown, base rounded, margin strongly revolute, apex rounded, extrafloral nectaries along margin c. 12, basal ones usually not obvious; venation distinct, sunken above, strongly raised below, covered with simple hairs underneath and basal part of midrib above, marginal vein distinct, nerves 5–8 pairs, at 34–41° angle with midrib, tertiary nerves perpendicular to midrib and secondary nerves, distance between tertiary nerves 0.3–0.6 cm; higher order nerves scalariform to reticulate. Inflorescences axillary, very short thyrses, single, c. 0.8 cm long, flowers seemingly fasciculate, but peduncle c. 0.2 cm long, erect; bracts not well visible, c. 0.5 cm long. Staminate flowers c. 8.7 mm diam; pedicel 3.5–5.5 mm long; buds c. 3.5 mm diam, covered with simple and lepidote hairs, sepals 2–3, elliptic, margin entire, c. 3.9–4.4 by 2.9–3.2 mm, valvate, free; stamens c. 33, filaments c. 4.7 mm long, anthers c. 0.6 mm long. Pistillate flowers, fruits and seeds unknown.

Distribution — Borneo ( Sarawak; only known from the type). Habitat & Ecology — Flowering: November.

Note — Airy Shaw (1965) was not certain if this species belonged to Blumeodendron , but the absence of stipules, the ruminate staminate disc glands and the presence of orange lepidote hairs on the buds are all indicative of only Blumeodendron .
