lumined tracheal and parenchymatous elements there exist¬ 
ing. The heart wood contains a fair percentage of fibres of 
narrow lumen. Trees of this species are certainly worth a

which I have seen at Ambalawa, near Gampola. 
Distribution .—Endemic and rare, limited to moist region, 
1,500-4,000 feet ; Deltota, Uduwella, below Haputale, Han- 
tane, Gangaruwa, Kalugalla, Ambalawa. 
KEYS TO THE CEYLON SPECIES OF DIOSPYROS . 
OeneraS Characters. 
The following key is based on the general characters of 
the leaves, fruits, and stems, and may be found useful as

be no difficulty in identifying species of Diospyros in the 
forests of Ceylon.
