<div type="etymology" lang="la"><p>Tomentosus - densely covered in small hairs</p></div>

<div type="vernacular"><p>rotan tukas</p></div>

<div type="description"><p>Clustering rattan climbing to 20 m tall. Stem without sheaths to 1 cm in diameter, with sheaths to 2.5 cm, with internodes to 35 cm long. Sheaths with scattered rounded swellings each tipped with black upward pointing spine to 2 mm long, densely covered throughout with silvery flocculent indumentum drying yellowish, and caducous chocolate-coloured scales. Knee prominent. Ocrea to 1 cm high indumentose as the sheath. Flagellum to 1 m long. Leaf ecirrate or with a minute (1 cm long) cirrus vestige. Petiole to about 30 cm long. Leaflets 5 on each side of the rachis in mature leaves, diamond-shaped to 35 cm long by 18 cm wide, with no obvious stalk &#177; unarmed except for short bristles near the tip, with 7-9 major nerves; whole leaflet drying dirty yellowish green-brown. Inflorescence, male and female superficially similar, to 80 cm long with up to 5 partial inflorescences the largest to 35 cm long; male rachillae about 3 cm long; female to 8 cm long. &#177; mature fruit rounded to slightly oblong about 2.5 cm long 2.2 cm wide, shortly beaked, covered in 18 vertical rows of mid-brown scales.

<div type="uses"><p>The cane has a good appearance but it is probably too rare to be of any significance. Calamus tomentosus is a rare rattan found on steep slopes in hill forest up to about 800 m altitude.</p></div>

<div type="discussion"><p>It may be distinguished from the other rhomboid leafleted Calamus blumei by the yellowish colour of the sheaths on drying, the sessile leaflets with 7-9 ribs and the yellowish-brown tinge to the dried leaves.</p></div>
