 with hoary tomentum, soon glabrous on the upper surface, and at maturity dark yellow- 

 green and lustrous above, 2|'-4^ / long and 2^-5' wide; petioles stout, glabrous, I'-l^' in

 cent, the free portion f'-lj' long, its bract oblong-obovate, cuneate at base, rounded or 

 acute at apex, nearly glabrous on the upper surface when it first appears, pubescent be- 

 coming glabrous or almost glabrous below, 4'-5 / long and f wide, longer or shorter than and 

 decurrent to the base or nearly to the base of the peduncle; sepals ovate, acuminate, cili-

 the inner surface with long white hairs; petals lanceolate, acuminate, a third longer than the 

 sepals; staminodia oblong-obovate, rounded at apex, rather shorter than the petals; style

A large tree with slender red-brown glabrous or slightly pubescent branchlets. Winter-

Distribution. Coast of North Carolina (Wrightsville Beach and the neighborhood of 

 Wilmington, New Hanover County), southward in the immediate neighborhood of the

Tilia caroliniana var. rhoophila Sarg. 



Differing from the type in its pubescent branchlets and winter-buds, its usually larger 

 leaves, and in its tomentose corymbs of more numerous flowers. Leaves broad-ovate, 

 abruptly short-pointed and acuminate at apex, oblique and truncate or cordate at base,
