<div type="description"><p>Clustering, medium diameter rattan. Stem 25 m long or more, with sheaths 2 cm in diameter, without sheaths 1.2 cm. Leaf 1 m long, ecirrate; sheath green, spiny or glabrous, spines when present brown or black.flat, short on the younger sheaths, to 2cm long on mature sheath; knee prominent: ocrea slightly developed, petiole 14 cm long, margins armed with small spines; spines 0.3 cm long: rachis with a raw of small spines underneath, spines 0.5 cm long; leaflets 30-56 x 2.5 - 4 cm gradually becoming smaller towards the tip, basal part of the terminal pair united, dark green, linear lanceolate, regular, midvein prominent. Male inflorescence long flagellate, primary sheath tightly sheathing; partial inflorescence to 55 cm long; secondary sheath funnel-shaped; rachilla 7 cm long. Female inflorescence long flagellate, primary sheath tightly sheathing, spiny along the sides; partial inflorescence 55 cm long; secondary sheath tightly sheathing; rachilla 7 cm long, decrease in length distally; involucre cup shaped; fruiting perianth 0.4 cm long.

<div type="distribution"><p>In evergreen forests of Andamans (Map. 5) Very common in Baratang island.</p></div>

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

<div type="uses"><p>Used in furniture industry and for tying rafts.</p></div>

<div type="discussion"><p>The species display morphological variations in the diameter of the stem and in the armature of the sheath. Rogers himself has made a note of such variations on his sheets. We have found that the diameter of the cane uarlesfrom 0.5-1.2 cm In the same clump. The younger sheaths are more spiny than the older ones.</p></div>
