Pmtaspodon Motleyii (near). No. 304 — 



Large tree, 8 feet girth, bole 80 feet, 120 feet over 



all. Heavily buttressed to J 5 feet. 



Leaves. — Compound, alternate. Stalk, 4 to 7 

 inches, bearing four to five pairs of opposite or 

 eub-opposite leaflets; shortly petiolate, 3-1 6th 

 inch; blade, 3 to 5 inches x 1} to 1} inches; 

 lanceolate, acuminate with a somewhat blunt 

 apex; glabrous, thin; bark of twig scantily 

 exudes white latex. 



Bark. — g inch thick, grey; scaly; scales shedding 

 in large patches; inner bark brown; exudes 

 brown latex; scan'tily; solution colourless, no 

 precipitate. 



Wood. — Sap 1 inch, pale yellow ; heart deep brown, 

 which lightens to a pale brown on drying. 



Rays. — 200, brown, sinuous, l-80th inch deep; fine 

 rather indistinct lines 



on quarter. 



Pores. 



Clear, 7,000 to 9,000, single, more rarely radially 

 septate; a relatively small number are filled with 

 a yellow-brown deposit. Soft tissue. — Absent. 

 General. — A brown, straight-grained timber, 

 with an oily surface; shavings boiled in water 

 yield oil. Solution wood, colourless; pale-blue 



precipitate. 



Cut 



i rather hard, but works 

 smoothly; 52 lb. per cubic foot. 



Locality. — Baroi. 



t/ 



Date. — October. 



Native names. — Auro (Vailala), Inene (Evara). 



Remarks. — A dense, straight-grained wood, not 

 difficult to work. The wood contains an oil in 

 such abundance that it may he collected in 

 conveniently placed receptacles, much as rosin is 

 collected from the Maratime Pine — only the cut 

 must reach the heart. In many cases the flow 



is very heavy, and in one instance a gallon of 



the oil was collected in three hours. 



I 



n such 



1 



cases it is probable that reservoirs of oil have 

 been formed in hollows caused by rot, and the 

 axe has tapped a crack that has piped off the 

 supply. While a miscroscope may yield some 

 explanation of the formation of the oil in the 



wood, a lens shows no special canals or vessels as 

 one would expect to gee. The oil is heavy and 



misty brown in colour; it resembles motor lubri- 

 cating oil as used for cylinders. It has a smell 

 which is hard to describe though somewhat fami- 

 liar — somewhat fishy linseed oil is the nearest 1 



can get to it. 

 Material collected. — Leaves, bark, wood.
