= This small pyramidal tree produces the largest. 
aves and flowers of any other North American plant. 
The limits of this interesting epecies appear to be ex- 
tremely local. I first observed it in Tennessee near the 
banks of Cumberland river, but of very small size, In. 
the southern states it is not at present known to the most 
assiduous collectors in any other spot than a single nar-- 
row tract of about 2 miles in » 12 miles sag 
ber-nee,) Flowers yellowish 6. cordate. Flow- 
twice in the year in the garden of 
Mr. ie Philadelphia. Leaves subcordate-oval, 
lanceolate, auculate a the base. Considerably allied to 
M. macrophylla. P. pyramidata. Nothing. more than a va- 
riety of the preceding, having leaves altle — amd 
shorter.
