Leaves oval to elliptical-lanceolate or slightly obovate, acuminate at the ends, entire, thin, gla- 

 brous, dark green on the upper surface, pale on the lower surface, from 12 to 20 centimetres long 

 and from 3 to 6 centimetres wide, with narrow prominent midribs and thin slightly ascending 

 primary veins ; petioles slender, narrowly wing-margined at the apex, from 1 to 5 centimetres in 

 length ; stipules large, obtuse, apiculate, sphacelate-scarious, united into a sheath splitting down 

 one side, caducous. Flowers perfect, in sessile naked terminal corymbose cymes, enclosed in the 

 bud in the stipules of the two upper leaves, their primary and secondary divisions usually three- 

 branched ; calyx minutely five-lobed ; corolla tubular, white, villose in the throat of the tube, the
