 spatulate, with narrow claws, 4' long. Va. and Ky., along the Alleghanies,

 base. Buds flat, sheathed by the successive pairs of flat and broad stipules joined 

 at their edges, the folded leaves bent down on the petiole so that the apex points 

 to the base of the bud. (Name from \ipiov, lily or tulip, and SeVSpoi/, tree.)
