Biology And Ecology

  • A dominant rattan species in the middle and upper hill forests (1500 - 2500 m altitude) of eastern Himalaya. (S.K. Basu, Rattans (canes) in India. A Monographic Revision. 1992)A

Common Name

  • Tehri Bet, Runul Bet, Rano Bet. (S.K. Basu, Rattans (canes) in India. A Monographic Revision. 1992)A

Uses

  • Canes are soft and therefore unsuitable for furniture making; used by the hill people for tying fences and for making tea baskets for plucked tea-leaves. (S.K. Basu, Rattans (canes) in India. A Monographic Revision. 1992)A

Description

  • A high climbing rattan; stem clustering, with leafsheath 2-4 cm in diameter. Leaves cirrate about 2.5 m long; leafsheath semi-woody, covered outside with spirally disposed 1.5-2 cm long needle-like brown spines; petiole absent in adult leaves; rachis 3 cm broad, armed below with single row of digitate claws; leaflets alternate to irregularly disposed on rachis, 5-nerved, 30 - 40 cm long, 2-3 cm broad at middle. Inflorescence with 1 m - 1.5m long pendulous primary flower branches; primary bracts tubular, obliquely truncate with triangular appendage on one side, tomentose at base; flower branches 60-80 cm long, slender, sinuous, covered with alternate, triangular-ablong, acute to acuminate, 4-5 cm long, 5 cm broad bracts; bracteoles in male rachilla subulate; male flowers sessile, trigonous, 7-8mm long; petals much longer than calyx, lanceolate, acuminate; stamens with subulate filaments; anthers broadly linear, 4 mm long; pistillode with 3 rudimentary papillae. Female flowers about 9 in number in each bract, biseriate; each 8 - 9 mm long; calyx shortly cupular, with 3 long, acuminate teeth; corolla with 3 concave acuminate petals; ovary globose with non-laciniate scales; stigma sessile, trigonous. Fruit 1.5 cm in diameter, not wooly outside; fruit scales numerous arranged in longitudinal series with pappilose margins and obtuse tips; seed orbicular, depressed, 1 cm in diameter. (S.K. Basu, Rattans (canes) in India. A Monographic Revision. 1992)A
