It is a small one-seeded samara, surrounded with a thin membranous wing about one-half of an inch long and hairy all over. The bark on the main trunk is thick, ridged with wide furrows separating flat scaly ridges. The twigs are at first light-brown and hairy, become shiny reddish-brown, finally grayish-brown with corky winged projections.
