Dipterocarpus.'] DiptevocarpacecB . 115 



anth.; ov. pubescent; fruit.-cal. 7 in., tube i| in., bluntly 

 5-ribbed down part or whole length, urceolate, wings strongly 

 3-veined, reticulated, smaller lobes about i in., broad-oval, 

 very obtuse, nut about i in., ovoid-conical, blunt, finely silky. 



Moist low country and extending into lower montane zone ; common. 



Fl. February. Pet. purplish-red with a yellow border. 



Endemic. 



Affords a greenish-grey semi-liquid gum-resin. 



Wood moderately hard, rather light, red ; not durable, but great 

 lengths can be obtained, which makes it valuable for scaffolding and 

 other temporary purposes. 



The ribbing of the fruiting cal.-tube is often very slight, but the fruit 

 can be distinguished from that of D. hispidus by the different venation of 

 the wings. 



\D. turbinatus, Gaertn. f., has been said to be cultivated in Ceylon, 

 but erroneously so (see Thw. Enum. p. 402) ; C. P. 2398, above quoted, 

 was at first thought by Thwaites (1. c. p. 34) to be this species. It 

 affords the Gurjun oil of medicine, and is a native of the Malay Penin- 

 sula.]

A large tree ; young twigs with copious adpressed hairs ; 

 1. 6-9 in., oblong-lanceolate, rounded or acute at base, shortly

 hairy beneath, lat. veins 12-18, petioles | in. or more, densely 

 adpressed-hairy ; fl. not seen ; fr.-cal. 4-5 in., tube oblong- 

 ovoid, with 5 strong marked, broad, undulated, vertical wings, 

 generally reaching to the base, slightly stellate-pubescent ; 

 lobe-wings 3-4 in., somewhat undulated mottled, smaller lobes 

 oblong-rotundate, much undulated and crumpled. 



Moist low country ; very rare. Near Ratnapura. Fl. not collected. 

 Endemic.

 C. P. 2590. 



Fl. B. Ind. i. 297. 



A large tree; young parts hairy; 1. 3-5 in., oblong-oval, 

 rounded at base, shortly acuminate, entire, glabrous above, 

 except on midrib, finely stellate-pubescent and glandular 

 beneath, lat. veins 11-13, petioles |-i in., stellate-hairy, 

 stip. \\ in., with tufts of long stellate hair outside ; fl. \\ in. 

 ■diam., few, in short axillary racemes, ped. stellate-hairy ; cal. 

 stellate-pubescent, with a narrow campanulate tube, promi- 

 nently and bluntly 5-winged ; pet. stellate-pubescent outside ; 

 fruit-cal. 4-4^ in., nearly glabrous, tube globular-ovoid, with 

 5 strong narrow vertical wings reaching nearly to the base ; 

 Jobe-wings (often 3) 3J-4 in. long.
