Arbor circiter 12 m alta, partibus junioribus et inflorescentiis 

 exceptis glabra; foliis confertis, majoribus obovatis, usque ad 

 15 cm longis, apice latissime rotundatis, nervis utrinque circiter

A tree about 12 m high, the younger parts and inflorescences 

 more or less pubescent. Branches reddish-brown, rugose, 6 to 

 8 mm in diameter, glabrous, the branchlets somewhat cinereous- 

 pubescent. Leaves crowded at the apices of the branchlets, very 

 diverse in size, the larger ones broadly obovate, 8 to 15 cm long 

 with about 8 pairs of primary nerves, apex broadly rounded, 

 gradually narrowed below to the acute or subacute base, the 

 smaller ones oblong to obovate, 2 to 6 cm long, all chartaceous, 

 pale to brownish when dry, glabrous or the younger ones some- 

 what pubescent along the midrib on both surfaces, the lower 

 surface somewhat puncticulate ; petioles pubescent, 4 mm long 

 or less. • Cymes in the uppermost axils, long-peduncled, 9 to 11 

 cm long, more or less pubescent, many-flowered, each cyme 

 about 4 cm in diameter. Flowers pinkish-white, fragrant. 

 Calyx pubescent, about 4 mm in diameter, usually 5-angled or 

 toothed. Petals 5, oblong, puberulent, about 10 mm long, 3 to 

 4 mm wide. Staminal-tube glabrous, about 2 mm high, the 

 filaments usually 12, 2.5 to 3 mm long, the alternate ones slightly 

 shorter than the others, densely villous inside. Ovary and style
