Seedlings epigeal, cotyledons detached early, epieotyledo- 

 nary system slightly enhanced developmentally . Cotyledons 

 white, 10-13 mm. long, 4-6 mm. wide; hypocotyl white, 

 glabrous, very short type similar to D. oocarpa and suggest- 

 ive of hypogeal tendency ; seeds are never raised above the 

 ground and the hypocotyl is never strongly arched ; 15-20 mm. 

 long. Epicotyledonary system is long and narrow and easily 

 frees itself from the confines of the decaying cotyledons and 

 endosperm, and at the time of detachment of cotyledons 

 measures 10 mm. in length and 1-5 mm. diameter. 



The epicotyledonary stem when 65 mm. long bears 3-5 

 small leaves about ] mm. in length and disposed at irregular 

 distances ; at the apex there are two larger leaves, opposi te, but 

 at different levels ; these are glabrous, thin, bullate, and 

 measure 50 mm. in length. 



Traces 3 per cotyledon, xylem splits at different levels of 

 hypocotyl and primary root. One trace per epicotyledonary 

 leaf, but on account of splitting of cotyledonary xylem diffi- 

 cult to follow. 



Timber. Trimen (p. 100) describes the heartwood as being 

 small and black with pale streaks, and states that it is one of 

 those called ''kalumediriya" the Sinhalese name for cala- 

 mander. At Ratnapura I found this belief still strong and it 

 was only after much persuasion that trees on private grounds 

 were felled for my inspection. Every specimen which I have 

 seen is white when freshly cut, turning a dirty colour on 

 exposure. Only on one occasion was the black heartwood 

 present and this was very small and rotten. (See pi. III., 

 fig. 3). 



The gum-resin is present in very small quantities; the soft 

 parenehymatous tissues are very abundant, and the timber 

 must therefore be regarded as of an inferior quality. The 

 tree provides excellent straight posts and is therefore fre- 

 quently felled. The rings of growth are very inconspicuous, 

 sometimes they occur as broad dark bands alternating with 

 narrower and lighter zones. These are sometimes so closely
