DIPTEROCARPACEAE. 



3. Balanocarpus ovalifolius, sp. nov. 



Tree. Leaves thin coriaceous ovate, cuspidate, base 

 round shortly acuminate, tip blunt, nerves line about nine 

 pairs, often very inconspicuous, midrib elevate often on 

 both sides reticulations minute but conspicuous 3 in. long, 

 1-5 in. wide, petiole slender -5 in. long. Panicles lax, 

 glabrous, drying black, 2 in. long, rather few flowered. 

 Flowers considerably larger than in. B. Curtisii. Sepals 

 imbricate subcoriaceous, glabrous blunt. Petals twice as 

 long 15 in. long, oblong, blunt mealy pubescent outside.

 stamens. Ovary with stout cylindi-ic stylopediujn, glabrous. 



Penang : Ayer Hitam at 300 ft. (Haniff 3727, Curtis 

 426) . Malay name " Pinang Baik." 



This plant was originally tentatively assigned to B. 

 laitfolius Brandis, a Bornean species, by Brandis ; but it 

 differs entkely in the venation of the leaves which is exactly 

 that of B. Curtisii. From that species it differs in the 

 broad ovate leaves and larger flowers apd more oblong 

 longer sq)als.

Prostrate, creeping shrubby plant 2 ft. long, twigs 

 slender, tips tomentose. Leaves ovate elliptic, base broad, 

 edge serrate tomentose, thickly beneath, thinly above when 

 adult nerves thick elevate 3-4 pairs -5- -75 in. long, '25- -3 

 in. wide; petiole -25 in. long, stipules Linear. Heads of

 villous. Calyx obconic strongly nerved, villous, lobes 5 

 subulate. Corolla -25 in. yellow, petals linear oblong

 seeded. 



Kelantan in sand on the sea shore beneath the 

 Casuarinas at Kuala Kelantan. Abundant. 



An interesting find as W. indica L., the only other 

 Asiatic species, is a tropical weed probably like most of 

 the genus of American origin. It is an erect plant and is 

 not common in the Malay Peninsula being only known 

 from Malacca where Griffith collected it.
