Discussion

  • Plectocomiopsis corneri is an extremely distinctive rattan found in lowland freshwater swamp forest and lowland Dipterocarp forest on the East Coast from Trengganu to Johore and one locality (G. Bubu) in Perak. It is nowhere very common, usually being found as occasional clumps. It appears to be favoured by disturbance - in areas where this species is indigenous, especially fine clumps may be seen along old logging trials. This species can hardly be confused with any other, it is the only Malayan rattan with the combination of non-kneed sheaths, prominent truncate ocrea bright yellow in colour, and broad cucullate leaflets, and very sparsely armed or unarmed sheaths.

Uses

Description

  • Robust high climbing clustering hapaxanthic rattan with stems to about 25 m tall, without sheaths 1.5 - 2 cm in diameter, with to 3.5 cm. Internodes to 40 cm on juvenile stems, usually much less. Sheaths rich bright green, with thin covering of silvery grey indumentum and very sparse spines, most sheaths inerm, spines normally only present on juvenile stems, as a vertical row of golden spines about 3 cm long, below the petiole. Knee absent. Ocrea very conspicuous, about 3 cm high, though shorter in adult flowering stems, orangey-yellow, truncate, not tattering. Leaf to 2.75 m; petiole non-existent or very short; leaflets about 9 on each side of the rachis, very broad, somewhat cucullate about 30 cm long by 7 cm wide, bright green; cirrus to about 1.25 m. Dimensions of leaves subtending inflorescences much smaller. Inflorescences produced in the axils of the topmost 5-10 reduced leaves, male and female superficially similar but male more highly branched than female, unarmed, to 30 cm long with rather curving divaricate rachillae. Fruit borne on persistent, greatly enlarged and split calyx; fruit somewhat wider than high, about 2.5 cm high and 3 cm in diameter, covered in pale bright orangey-brown scales in 30-35 rows. Seed somewhat depressed, covered in very thin flesh. Endosperm homogeneous. Seedling leaf bifid flagellate, of very thin texture. (J. Dransfield, A Manual of the rattans of the Malay Peninsula.
