are of a deep green colour ; cotyledons white, 20 mm. long, 
12 mm. wide ; hypocotyl white, thinner than D. Moonii, 85-90 
mm. long; epicotyledonary stem pubescent, a trifle longer than 
D. Moonii, 6-10 mm. long ; epicotyledonary leaves form an 
opposite pair, cordate, tapering acute apex, midrib hairy 
beneath, 25 mm. long, 20 mm. broad. Three traces per 
cotyledon, xylem of median trace abortive and liable to be 
overlooked in sections not horizontal ; one trace per epico¬ 
tyledonary leaf, continued into the root but in old seedlings 
absent from the apical part of the root. 
Timber .—The sapwood when freshly cut presents a dirty 
appearance while the heartwood is light red. There is no real 
black heartwood, only small black traces here and there. The 
coloured materials in the various elements are small in 
quantity ; fibres are abundant and medullary rays poor, hence 
an even-grained timber results. Rings of growth some¬ 
times conspicuous, the light narrow rings measuring 02-T2 
mm. radial diameter and being distanced 2-8 mm. radially 
from one another. (See pi. II., Fig. 9). 
Distribution .—This species is found in the moist low- 
country forests, rather rarely; it grows well on moist, rocky, or 
sandy soils, and under close canopy usually measures 4*5-6 
metres (15-20 feet) to first branch, and has a total height of 6- 
9 metres (20-30 feet), the average circumference being about 
320 mm. The largest trees occur at Hiniduma at an elevation 
of 800 feet, measurements already quoted. Ratnapura, Hini¬
