WRIGHT : THE GENUS DIOSPYROS 
being quite rotten. On exposure the timber changes to a 
darker colour with irregular streaks of black, often giving a 
pattern to the transverse section similar to what has been 
noted in D. ovalifolia. (See pi. II., 8). 
The discolouration is often due to a change in the colour 
of the cell walls only. The relative scarcity of gum-resin 
and the abundance of parenchymatous cells, particularly of 
the medullary ray, necessarily make the timber very inferior 
in quality. 
The rings of growth are inconspicuous. 
Distribution .—This is our rarest species of Diospyros and 
up to the present has only been found on the upper part of 
the Haycoek mountain, or Hinidumkanda, between 1,500- 
2,000 feet. The climate there prevailing is unique, the upper 
part being, more often than not, capped with mist, and 
arborescent vegetation is of a stunted xerophytic type. 
There are not more than 40 or 50 trees of this species and 
these occur mixed with trees of calamander. The character 
of the erect trunk with its black bark is very similar to that 
of calamander trees, and the fact of their being so freely 
mixed with trees of calamander is probably the source of 
the error regarding the value of the timber. This species 
should grow well on the steep rocky hill sides in the Peak 
Wilderness, where the rainfall is high.
