A__Laxge acacgreen tree, dioecious, polygamous, and 



occasionally m oagecious, trunk erect jmd_J ! oliage dense ; 



_hark think, dark ff rm nr black, occasionally scaly, finely 



grooved in bra^MP Qr>rl < " a ngfi. 



Leaves alternate, numerous, spreading dichotomously, 

 very variable, 50-130 mm. long, 20-60 mm. wide, oblong- 

 oval or oblong-lanceolate, acuminate, rounded or obtuse 

 apex, usually narrowed at base, glabrous, thinly coriaceous, 

 bright green and shining above, paler beneath, venation 

 strongly reticulate and pellucid, and meshes wider than in 

 D. Toposia. Petiole 4-8 mm. long, green, glabrous. 



This species could be arranged to include several varieties 

 according to variation in size, venation, and form of the 

 mature leaves. 



The monoecious state is rarely met with. I have seen it 

 in the forests near Dambalagala Trigonometrical Station, 

 Central Province, at an elevation of 1,900 feet, on rocky damp 

 slopes. At this place one tree possessed the ordinary male 

 flowers with indefinite connate stamens and rudimentary 

 pistil, and female flowers each with 8 barren staminodes, 

 typical calyx, and gynaecium. (See pi. XIII., fig. 5.)
