This resembles X. adenotus, Miq., but differs in venation of leaves 

 and in inflorescence. 



19. Xanthopiiyllum sulphureum, King, n. sp. A tree 100 (or even 

 160) feet high ; branches with very dark brown bark, the youngest 

 minutely tomentose. Leaves coriaceous, drying bright yellowish-green, 

 elliptic-oblong, sometimes sub-obovate, acuminate, the edges recurved 

 when dry, the base cuneate ; upper surface glabrous, shining ; lower snl- 

 phureous, softly but minutely pubescent especially on the midrib and G 

 to 7 pairs of prominent ascending nerves ; length 5*5 to 7*5 in., breadth 

 2 to 2"5 in., petiole '5 to "65 in. Flowers '4 in. long, the pedicels about 

 as long as the calyx. Panicles tomentose, with ovate deciduous bracts, 

 compact, many-bran ohed, axillary or terminal, less than half the length 

 of the leaves. Sejpals unequal, ovate-rotund, minutely tomentose on 

 both surfaces, the edges ciliolate. Petals oblong, obtuse, glabrous 

 except the pubescent tips ; the keel obovate, vertically 9 to 10-ridged, 

 tomentose. Filaments flattened, glabrous. Ovary shortly stipitate, gla- 

 brous, ovate, S-ovuled, surrounded at the base by a fleshy glabrous much

 half. Fruit (young) globose, sulphureous, glabrous, faintly rugose. 

 Perak, on low hills. 



Not unlike X. rufum, A. W. Benn. in general aspect : but with 

 smaller flowers, glabrous ovary and fruit, and leaves intensely sulphu- 

 reous beneath.

 ovate or obovate-elliptic, very shortly and suddenly acuminate, narrow- 

 ed in the lower third to the stout short petiole, the edges recurved when 

 dry ; upper surface glabrous, dull ; lower paler, covered with short soft 

 pubescence especially on the midrib and 7-8 pairs of bold semi-erect 

 nerves ; length 4*5 to 6*5 in. (acumen *5 in.,) breadth 2*25 to 2*75 in,, 

 petiole "5 in. Panicles terminal or from the axils of the uppermost 

 leaves, lax, few-branched, 3 to 7 in. long, densely tomentose, the ends 

 of the branches and sepals rufous. Flowers '6 in. long, on short pedicels 

 in the axils of ovate sub-persistent bracts. Sepals unequal, ovate to sub- 

 reniform, densely tomentose on both surfaces, fleshy, concave Petals 

 more than twice as long as the sepals, oblong, obtuse, glabrous except 

 the tomentose keel. Filaments glabrous, flat at the base. Ovary sur- 

 rounded by a shallow fleshy disc, sessile, ovate, pointed, ridged, tomen- 

 tose as is also the conical style ; ovules 12 to 16. Fruit 75 in. in diam., 

 (? mature) globose, with 4 vertical rufous pulicsccnt ridges; pericarp
