AVood. — Slightly resinous. Sap undefined, cream 

 coloured. 



Kays. — 150 to 160; yellow; somewhat sinuous 

 around pores. l-30th inch; show up as specks, 

 and lines on quarter. Pore-. — Clear. 5,000 

 to 7,500; single and radially septate (2, rarely 

 3); sometimes tangentially septate; in zones of 

 very porous and less porous wood. Soft tissue. 

 Short, fine, scarcely visible broken lines here 

 and there join up pores, but the main soft tissue 

 consists of fine continuous concentric 

 undulate white rings. These are sometimes 

 doubled, trebled, or quadrupled. Sometimes 

 they are so close as to form one line l-20th inch 

 thick, but more often they are separate if close 

 together. The hard tissue around is more 

 porous than elsewhere, but the pores are small.

Locality. — Vailala River. 



Date. — December, 1922. 



Native names. — Kokolaka (Vailala) ; Bou-ura

Remarks. — The resin is collected, and is used for 

 torches and for tatooing. It exudes copiously 

 from holes made by boring insects. Sometimes 

 it is clear and yellow, but for the most parr it 

 is an opaque white resin 

 grease on the bole. Curiously enough, while 

 obviously a good resin it has only been exported 

 from Sud Est. In Sydney it is used for 



looking like candl
