Dedap

INTRODUCTION

The common Malaysian name for the trees and timber of Erythrina spp. (Leguminosae). Vernacular names applied include dadap (Sabah). Major species include E. fusca and E. variegata. The sapwood is not differentiated from the heartwood, which is pale straw- or buff-coloured.

Also known as Dedap (Indonesia); Kathit (Myanmar); Dap-dap (Philippines); and Thong lang (Thailand).


DENSITY

The timber is soft and light with a density of 240-380 kg/m3 air dry.


NATURAL DURABILITY

The timber is non-durable and susceptible to sapstain fungi and dry-wood termites.


TEXTURE

Texture is coarse and uneven due to the presence of broad rays and the abundant parenchyma. Grain is straight, shallowly interlocked or wavy.


MACHINING PROPERTIES

It is easy to work but difficult to finish because of the coarse texture.


SHRINKAGE

Shrinkage upon seasoning is moderate to high.


USES

The lightweight wood of dedap is suitable for use as floats for outrigger canoes and fishing-nets, surfboards, dugout canoes, shields, spears, helmet, insulator boards, wooden shoes, carving, kitchen utensils and match splints.
