 conspicuous, gradually curved to the apex, the upper one-half to one-

 the inner by cross nerves ; main nerves about 6 pairs, arched ; 

 secondary nerves many, similar to but fainter than main nerves ; 

 reticulations irregular ; petiole -3 to -5 in. long, black when dry,

 at tip only, in pairs, about 1 to 1"5 in. long, circinate, thickened up- 

 wards, supported by 2 small acute stipules, on a -75 in. long stalk, each 

 pair replacing a leaf near the ends of the branchlets. Leaves sub- 

 coriaceous, elliptic-ovate or -oblong, acuminate at apex, rounded at 

 base ; glabrous on both surfaces ; 3 to 6 in. long, 1-25 to 2-5 in. broad ;

 raised, impressed above, as are the 2 inner ribs, which curve somewhat 

 acutely upwards to the apex, not or only slightly looped above half- 

 way up ; outside them and close to the margin another pair more or 

 less inconspicuous, making an intramarginal looped nerve ; main nerves 

 faint, 6 to 8 pairs, rarely opposite, straight from the midrib to join the
