appressed stellate hairs; leaves with petioles appressed tomentose on under- 
surface, up to 2 cm. long; leaf blades obovate, oblanceolate or oblanceolate- 
elliptic, 10-20 cm. long, 4-8 cm. wide, apex rounded and abruptly acuminate, 
base acute and decurrent, chartaceous, crenulate to subentire, pubescent on
