 Lofty trees, stellately pubescent or more or less clothed with fascicled 

 hairs. Leaves coriaceous, eiltire or siniiate-crenate, lateral nerves not quite

 usually more or less tumid at the apex ; stipules large, valvate, enclosing 

 the terminal bud, finally caducous leaving an annular scar. Mowers large,, 

 racemed, white or reddish. Oalyx-tube free. Petals usually pubescent ex- 

 ternally especially on the outer margin. Stamens <x> ; anthers linear, equi-
