Locality. — Hydrographer's, Northern Division, 

 2,000 feet, Between the Gap and Kagi, 5,000 

 feet. Between Kagi and Uribaiva, Central Divi- 

 sion, at altitude of between 2,500 and 4,000 feet. 

 On hills between Uberi and Sogeri, Central Divi- 

 sion, at 2,000 to 2,500 feet. 



Date. — Fruits in Llydrographer's in August. 



Native name. — Kini (Pernambata). 



Remarks. — The trees in the Hydrographer's were 

 not so well grown as those I met corning down 



from the Gap to Sogeri. The timber is a typical 

 oak or beech type. The serration of the leaf 

 does not appear to be a fixed character. Leaves 

 at top of tree are entire. A wide range over 

 upper foot-hills of New Guinea. 

 Material collected.- — Leaves and fruits, wood and 

 bark.

 radial snake-like lines; immersed in soft tissue. 

 Soft tissue. — Conspicuous; surrounds and links 

 up pores, also in x^vy fine wavy lines link up 

 the fine rays and coarse rays like the rungs of a 

 eellarnian's ladder. General. — A. brown oak 



with a very loud quarter grain, and charac- 

 teristically free splitting on the quarter. A 

 heavy structural timber. Solution wood : colour- 

 less; green precipitate. Cuts very hard, leaving

Locality. — Between Menari and Efogi, 5,000 feet 



to 8,000 feet. 



Date. — February, 1023. 



Remarks. — This oak is found growing with the 

 Smaller acorned species, and is hard to distin- 

 guish. The host way is, I think, by the colour 

 of the cambium layer after exposure. Both 



oaks can also be confused with
