Lasianthus crinitus Hook.f. (1880) 182. —

Type: Wall. Cat. 8441, p.p. (holo K), Peninsular Malaysia, Penang, or Singapore .

Shrubs; branchlets terete, c. 3 mm diam, densely brown-tomentose. Leaves: blades oblong, 10–15 by 2.5–4 cm, coriaceous, glabrous above, densely brown-tomentose beneath, apex acute to acuminate, base rounded, margin reflexed, midrib and nerves flat to slightly depressed above, prominent beneath, nerves 8 –9 pairs, ascending at an angle of c. 50°, curved to the margin, nervules distinct above, distinct and prominent beneath, parallel; petioles 3–4 mm long, densely brown-tomentose. Stipules inconspicuous. Cymes sessile; bracts numerous, filiform, up to 1 cm long, densely tomentose, forming a dense head. Flowers clustered, sessile; calyx and corolla not seen. Drupes globose, c. 3 mm diam, densely brown-tomentose, 5-ridged, crowned by 5 linear calyx lobes which are c. 2 mm long and tomentose; pyrenes 5.

Distribution — Peninsular Malaysia.

Note — This species has branchlets and leaf blades beneath rusty-tomentose, cymes sessile, bracts filiform, dense and nu- merous. The type is a fragment mounted with two other taxa, i.e. L. attenuatus and L. attenuatus var. minor on the same sheet. Only one specimen from Peninsular Malaysia (FRI 15716 from Fraser’s hill of Pahang) in L that we examined matches the type and description. This species is closely related to L. lineolatus Craib by its indumentum and bracts.
