CURIOUS LEAVES. 
THE leaves of trees not infrequently present sports or deviations 
from the ordinary types characteristic of the species, and occasionally 
these sports are of botanical interest. A few collected near Dayton, 
Ohio, during the autumn months of last year, are here figured. 
A twig from an American elm has a terminal leaf with its basal 
margins grown together, forming a short funnel-like cavity, with a 
very oblique upper rim. The third last leaf presents a similar funnel- 
like cavity at its base, but the leaf blade is supplied with two midribs 
and leaf tips. The second last leaf shows two midribs and leaf tips, 
but the basal margins of the leaf blade have remained separate (/igs-

small leaves with the usual pointed leaflets. In the figure (fg. 3) all
