INTRODUCTION

The common Malaysian name for the trees and timber of Helicia spp. and Heliciopsis spp. (Proteaceae). No other vernacular names have been recorded. Major species include Helicia rufescens, Heliciopsis montana and H. rufidula. The sapwood is yellow-pink and is sharply differentiated from the heartwood, which is brown with a salmon pink tinge.

Also know as Kendung (Indonesia); High mountain silky oak (Papua New Guinea); and Mueat khon (Thailand).


DENSITY

The timber is moderately hard and moderately heavy to heavy with a density of 515-785 kg/m3 air dry.


NATURAL DURABILITY

The timber is non-durable.


PRESERVATIVE TREATMENT

The timber is resistant to pressure impregnation. 


TEXTURE

Texture is slightly coarse and uneven due to the presence of the extremely broad rays.


MACHINING PROPERTIES

The timber saws easily and planes to a smooth surface.


AIR DRYING

The timber is reported to season well, with very little end-splitting and slight surface-checking as the main sources of defects.


USES

The timber has not been used extensively but should be suitable for cabinet making, superior joinery, high class furniture and interior finishing due to the presence of the oak-like silver figure.
