Meraga

INTRODUCTION

The common Malaysian name for the trees and timbers of Metadina trichotoma and Pertusadina spp. (Rubiaceae). Vernacular names applied include berombong (Peninsular Malaysia), kurau (Peninsular Malaysia) and mengkeniab (Sabah). Major species include Metadina trichotoma; Pertusadina eurhyncha and P. malaccensis. The trees of this genus have a very unusual form, in that the trunks appear to have slots all over, producing a lattice-like effect. The sapwood is lighter in colour but not sharply differentiated from the heartwood, which is yellow-brown with an olive tinge.

Also known as Berumbung, Kayu kunyit, Ki anggrit and Nangi kuning (Indonesia); Adina and Zschokke adina (Philippines); and Khamin, Khem chang and Lang khao (Thailand).

TEXTURE

MACHINING PROPERTIES
