"description"><p>Slender clustering rattan climbing to c
10 m; stems without sheaths c
8 mm diam., with to
15 mm diam.; internodes to
20 cm. Sheaths pale green with scattered brown scales and armed with scattered large triangular dark brown spines to
10 x
5 mm with swollen yellowish bases and black hairy margins, and much smaller spines to
3 mm scattered in between or in short groups. Knee conspicuous. Ocrea short, fringed with stiff blackish hairs. Vestigial flagellum present to
5 cm. Leaf to
1.25 m including cirrus to
70 cm and very short petiole to
5 cm; cirrus armed with scattered not grouped spines; leaflets c
10 on each side of the rachis, irregularly arranged in four groups of
2 or
3; longest leaflets to
40 x
3.5 cm, plicate, unarmed except for a few black bristles at the tip. Male and female inflorescences superficially similar, to
50 cm, with a short peduncle to
11 cm; main bracts to
15 cm, dull dirty brown covered in brown scales and scattered spines, deeply split and tattering giving the whole inflorescence a dead appearance; male and female rachillae to c
4 cm. Ripe fruit large, wider than high, to
18 x
23 mm, tipped with a cylindrical beak to
1.5 x
1.5 mm and covered in
24 -
26 vertical rows of deep reddish brown scales; seed

29 <div type=
"discussion"><p>The presence of a vestigial flagellum as well as a cirrus indicates that this species belongs to the group of species related to C. pogonacanthus. The highly tattered inflorescence bracts distinguish it from C. pogonacanthus and the
± unarmed leaflets differentiate it from C. hepbumii. A sterile specimen from Bt. Si lam (JD
5841) may possibly belong to C. mesilauensis.
