A. lofty tree; trunk 1.5 m thick, terete and straight, 20 

 m high at least; branches widely spreading, the young por-

 nate, alternating toward the ends of the thick branchlets; 

 leaflets subopposite, coriaceous, glabrous except the nerves 

 beneath, the entire margins subinvolute, the recurved tip 

 acute or abruptly acuminate, base rounded or subtruncate, 

 ovately oblong, the basal ones much reduced, nearly 2 dm 

 long and 7.5 cm wide below the middle, curing dull brown; 

 midvein prominently raised beneath, fuligineus strigose even
