Q. Lamponga , Miq. 
A very common tree about 60 feet tall and through, leaves small 
with silvery backs. Acorns conic hemispheric hoary, with shallow 
cups. 
The wood closely resembles that of the preceding but has larger 
pores very crowded in broad rows. The sapwood is rather paler 
but not very distinct. A pretty wood but useless for building 
purposes as it soon decays and it is Said to be even useless for 
firewood, merely smouldering when burnt. Weight 40 lbs, 8 ozs. 
to 42 lbs. 15 ozs. 
The tree is objectionable on account of its habit of decaying up 
the centre and suddenly falling apparently for no reason. It is 
consequently dangerous near roads.
