Rootstock short and thick, crowned with rather numerous leaves and large scarious 
brown stipules 1-2 cm. long; petioles 2-20 cm. long, stout, brownish, rather densely silky, 
with ascending, in age spreading, hairs; leaflets very thick and coriaceous, brownish when 
mature, slightly silky above when young, but perfectly glabrous in age, strongly nerved 
and reticulate, densely silky-strigose and finely tomentulose beneath; the terminal one 
evidently petiolulate, broadly obovate, truncate, subobcordate or sometimes rounded at the 
apex and crenate above the middle, with the terminal tooth generally much smaller, 2-5
