ANDIRA INERMIS PDF

Description An excellent online database of a huge range of trees giving very good information on each plant - its uses, ecology, identity, propagation, pests etc. The heartwood is highly figured and decorative varying from yellowish-brown to dark reddish-brown; it is clearly demarcated from the narrow band of light brown to greyish-yellow sapwood. The texture is very coarse; the grain is straight to slightly irregular; lustre is raher low; there is no distinctive odour or taste. Bands of light coloured parenchyma tissue give the wood a distinctive figure. The wood is very hard, heavy, and very resistant to attack by fungi and termites. The wood air-seasons at a moderate rate with little degrade; once dry it is stable in service.

In most locations the tree will grow under varying rainfall and soil conditions. The Tree: Evergreen, unbuttressed, moderate-sized trees; diameters of 20 to 28 in. The Wood: General Characteristics: The narrow sapwood is pale brown to grayish yellow and usually clearly demarcated from the yellowish-brown to dark reddish-brown heartwood.

Bands of light colored parenchyma tissue give this wood a distinctive figure. Luster rather low; without distinctive odor or taste when dry; texture very coarse; grain only moderately irregular. Mechanical Properties: 2-in. Drying and Shrinkage: The wood air-seasons at a moderate rate with little degrade. Sapwood, during early stages of drying, is susceptible to discoloration by sap-stain fungi.

Movement of seasoned wood is rather low. Shrinkage green to ovendry: radial 4. The wood works well in the lathe, holds nails and screws well and glues satisfactorily. Polishes and varnishes well after filling. Durability: Heartwood is resistant to attack by decay fungi and insects, but is only moderately resistant to dry-wood termites. Sapwood is highly vulnerable to power- post beetle attack. Preservation: Heartwood difficult to treat by both hot and cold bath and pressure- vacuum systems.

Absorptions are considerably less than 6 pcf with poor penetration Permeability of sapwood is also low. Uses: The wood is used locally for heavy construction, crossties, house framing, and exterior siding. Other suggested uses are turnery, furniture and cabinet work, parquet flooring, and decorative veneer. Additional Reading: 24 , 44 , 46 , 72 Food and Agriculture Organization.
