even on seedling plants ; they are composed of small undeveloped de- 

 flexed linear leaves with tubular bases. 



A very good varnish-resin is afforded by this tree. 



The name ' Yakahalu ' seems to be applied to this in the S. Prov. 

 The seeds are eaten after having been roasted. - 



8. D. ovalifolia, Thw. Enum. 402 (1864). Pini-beraliya, S. 



C. P. 371 1- 



Fl. B. Ind. i. 312. 



A large tree, young parts glabrous ; 1. usually small, 

 2-3 in., sometimes 4-4^ in., ovate or ovate-oval, rounded at 

 base, attenuate to long caudate apex, paler beneath, lat. veins 

 8-9, prominent beneath, petioles \-\ in., slender, channelled ; 

 fl. on slender, drooping ped., in few-fld, axillary racemes or 

 panicles shorter than the 1. ; sep. glabrous ; pet. pilose out- 

 side ; enlarged fruit -sep. a little over i in., wings oval- 

 spathulate. 



Moist low country; rare. Sabaragamuwa (Thwaites) ; Lihinigala, 

 Hewesse ; Timbera, Kukul Korale (Lewis). Fl. April. 



Endemic. 



Affords a good white resin. 



Similar leaf-galls to those mentioned under D. cordifolia are produced 

 in this tree also. 



The usual form is easily known by its small long-tailed leaves and 

 small broad fruit-sepals, but there is a larger-leafed tree which in the 

 absence of fl. and fr. is provisionally placed under this species. 



An allied species, unfortunately in leaf only, has been sent me by 

 Mr. Broun from Ingiriya Forest, near Labugama. It has the small 

 leaves broadly ovate, much less caudate, with 7-10 lateral curved veins 

 very conspicuously marked on the under surface, which is also very pale. 

 The local name was ' Yakahalu.' 



9. I>. oblongra, Thw. in Trim. Joicr7t. Bot. xxiii. 206 (1885). 

 C. P. 3986, 37i2(.?). 



A tree, young parts pubescent ; 1. 3|-4i in., lanceolate- 

 oblong, rounded at base, coriaceous, with a recurved margin, 

 lat. veins 8-1 1, distinct, curved, petioles \ in. ; fl. not seen; 

 enlarged fruit-sep. \\-\\ in., wings oblong-spathulate, thick, 

 nut \ in. 



Only known from the C. P. specimens which are without locality. 



Mr. Broun, Conservator of Forests, sends leaves which may be this 

 species from Kaniliya Forest, Hiniduma Pattu (where it is called 

 ' Beraliya '). 



C. P. 3712 is doubtfully referable to this (see under D. affinis).
