Uses, Qualities, etc. " House-building. Is readily procurable 

 in logs up to 40 ft. in length, squaring 6-9 ins." (2). Fissile, 

 takes nails badly ; planes hard but well ; turns moderately hard and 

 badly; polishes badly. Of doubtful value for export. Sometimes

ANATOMICAL CHARACTERS. 



The same as those of Bullet-wood, No. 12; Mamooriballi, No. 61 ; 

 Hymarikushi, No. 40; and Moraballi, No. 66. 



Transverse Section. Pores readily visible with the unaided eye ; 

 the branching lines are very plain and contrast well with the 

 ground, being much lighter, bigger and bolder and whiter than in 

 Nos. 40 and 61, while the concentric lines of Soft Tissue are hardly 

 so well developed and regular, but the Soft Tissue sheathing the 

 Pores is very striking. 



Type Specimens. Authenticated by Bell, No. 68/2724.
