20 m; stem without sheaths to
8 mm, with to
17 mm diam.; internodes
10 -
13 cm. Leaf sheaths dark green, covered in caducous scaly indumentum and armed with scattered large triangular spines to
10 x
10 m with black hairy margins and hollowed-out bases, interspersed with much smaller spines. Knee conspicuous. Ocrea membranous, inconspicuous to c
1 mm. Vestigial flagellum present to
20 cm armed with horizontal triangular spines. Leaf cirrate to
2.2 m, including petiole to
20 cm and cirrus to c
1 m; cirrus armed with scattered rather than grouped spines; leaflets linear to c
32 on each side of the rachis arranged in
4 -
6 rather distant groups, but regularly arranged within the groups, to
32 x
1.3 cm, somewhat plicate, very sparsely armed on the upper surface with
2 -
4 rows of scattered bristles, densely and conspicuously armed with short brown bristles all over the under-surface. Male inflorescence only known, to c
65 cm, curved; bracts on the axis dark brown, spiny and splitting longitudinally producing an untidy mass of strips; first order branches to

"discussion">C. hepburml although incompletely known, is easily identified by the presence of a vestigial flagellum and a cirrus with scattered rather than grouped spines, together with the linear leaflets densely bristly on the undersurface. It is to be hoped that more material will be collected. This rather elegant rattan was found in lowland Dipterocarp forest at the foot of an ultrabasic hill at Bt. Masasau, and in lowland Dipterocarp forest on poor soils at the edge of an old river terrace at Sapa Payau.
