<div type="description"><p>Clustering slender rattan with stems climbing to 20 m, branching in the canopy. Stem without sheaths to 4 mm diam., with sheaths to 8 mm diam., internodes c. 10 cm long. Sheaths dull green, bearing very few scattered, short triangular spines or unarmed, and with abundant deciduous black scales; ocrea tightly sheathing, to c. 2 cm long, net-like and bearing short spines. Leaf cirrate to c. 60 cm long including the cirrus to c. 35 cm, and short petiole 2-5 cm; leaflets 3-5 on each side of the rachis, with or without short stalks, rather narrow rhomboid, up to c. 15 &#215; 4 cm, the distal margins praemorse, upper surface usually shining green when fresh, lower surface covered with grey indumentum. Inflorescences produced from the topmost 1-3 nodes, small and rather inconspicuous, each with 3-4 slender rachillae to 90 &#215; 4 mm, the rachilla tomentum pale grey brown. Fruit not known. (Fig. 2).</p></div>

<div type="distribution"><p>A poorly known rattan, questionably recorded from scattered localities throughout Brunei. Elsewhere in Kalimantan, Sarawak and Sumatra.</p></div>

<div type="biology_ecology"><p>The few records from Brunei have been from mixed dipterocarp forest on gentle slopes and ridges in the lowlands and up to 870 m above sea level.</p></div>

<div type="conservation"><p></p></div>

<div type="uses"><p>Not known.</p></div>

<div type="discussion"><p>K. debilis is poorly known and can only be separated with confidence from slender forms of K. rigida when fertile. However the net-like ocrea seems to be consistently present whereas, in K. rigida it is normally truncate.</p></div>
