cracks about 10 mm. apart, running vertically through a 

 distance of 100-200 mm. ; peels off in large thin flakes expos- 

 ing brown surface ; young twigs thick, green and pubescent ; 

 the habit and bark characters are very pronounced. 



Leaves alternate or sub-opposite, 140-240 mm. long, 

 40-120 mm. wide, ovate-lanceolate or oblong, acute apex 

 rounded or narrowed at base, glabrous, toughly membrane 

 ous, pale green beneath ; venation conspicuous, midrib and 

 lateral veins project on lower surface, lateral veins connected 

 by parallel transverse veinlets ; petiole green, cylindrical, 

 glabrous, 15 mm. long, 2'5 mm. diameter. 



The polygamous state is very common ; the same stages as 

 determined in D. sylvatica, D. Gardner!, and D. affinis have 

 been observed for this species. The hermaphrodite and 

 male flowers occur on the same tree, showing all stages 

 between a central apiculate disc and a pistil with an 8-celled 

 ovary ; the hermaphrodite flowers may occur in the same 

 cluster as the male, or in separate clusters, the occurrence 

 being very erratic. (See pi. XIV., fig. 2). 



Male inflorescence consists of an axillary subsessile cluster, 

 3-10 flowers similar to those described for D. hirsuta; 

 flowers in March on stems 60 mm. diameter. (See pi. XIV., 

 %. D. 



Calyx green, 4 mm. long ; segments 4, short, accrescent, 

 ovate, acute apex, nearly glabrous. 



Corolla yellowish-white, shortly tubular, 10 mm. long, 

 narrow-throated when mature : segments 4, rotate, short, 

 pale and hairy outside. 



Stamens 14-16-20, epipetalous at base of corolla, single or 

 paired, inner shorter than outer, average length 5mm., very 

 unequal ; anthers brown, apiculate, longer than filaments, 

 length 3:5 (outer), 2 mm. (inner) ; filaments white, glabrous 

 or pubescent, length 3 mm. (outer), 0'5 mm. (inner). 



Pistil apiculate central disc, pubescent, 5 mm. high ; 

 crude locular structure seen in transverse section. 



The female flowers have not been previously described.
