Sonneratia acida L. f.; Rhizophora caseolaris L.; Blatti acida (L. f.) Lam.
It is a tree to 20 m tall and 30 cm diameter. The stems are frequently leaning and crooked.
Sonneratia occurs in mangrove forests along the seashore and on the banks of tidal rivers.
The high salt contents corrode metal (iron) elements in wood. The bark has a high tannin content.
Wood diffuse porous. Occasionally tangential diameter of vessel lumina 200 micras or more. Occasionally tyloses common. Vestured pits. Vessels per mm2 5 to 20. Vessels per mm2 more than 20 (very abundant). Vessel-ray pits reticulate and/or foraminate. Simple per Axial parenchyma absent or extremely rare, non visible with magnifying glass (8x). 4 to 10 rays per mm (medium). Rays more than 10 per mm (abundant). Rays exclusively uniseriate. Prismatic crystals in the ray cells. Body ray cells procumbent with one row of upright and/or square marginal cells (Kribs-III). Septate fibers present. Fibers with simple to minutely bordered pits.
The wood has fishy odor especially when fresh and with salty taste.
The heartwood is pale gray-brown to dark brown, clearly demarcated from the paler sapwood.
The grain is straight or slightly interlocked.
The wood is typically fine in texture.
The wood is moderately durable, but should not be used in contact with the ground in the tropics.
It is very difficult to treat with preservatives.
Ease of Drying: Drying is moderately easy; some particular care is needed. Drying Defects: Risks of checks. Kiln Schedules: Schedule proposed as a reference by comparison with well known species taking into account to the general technological behavior of this species.
Sawmilling of this species is reportedly fair.
It has a moderate dulling effect on the saw-teeth.
Wood processing is reported to be easy.
It takes a high finish.
Polishing of this species is reportedly easy.
