ASHE: TREES AND SHRUBS OF WASHINGTON 220 
MISCELLANEOUS SPECIES AND VARIETIES 
In addition to the forms of Amelanchier discussed above the 
following trees and shrubs, which apparently have not previously 
been credited to the Washington flora, have been found growing 
either in the District of Columbia or in nearby parts of Virginia 
and Maryland. 
Carya glabra hirsuta (Ashe) comb. nov. 
Micoria glabra hirsuta Ashe, Notes on hickories. 1896. 
Carya ovalis hirsuta Sargent, Bot. Gaz. 66: 247. 1918. 
This tree is not uncommon on rocky wooded slopes along the 
Potomac River at Great Falls, Virginia, and should be included 
among the trees which are characteristic of its flora. It has not 
been reported previously from north of North Carolina. 
Quercus PAGODA Raf. Alsog. Am. 23. 1838 
Edges of swamps near North Chesapeake Beach, Maryland. 
Not before credited to the Washington flora, although known from 
as far north as the island of Nantucket, Massachusetts. 
Quercus SHuMARDII Buckl. 
Growing with the preceding but not previously credited to the 
Washington flora. Attention has recently been called to the fact 
that Q. Schneckii Britton is a synonym of this species.* 
CRATAEGUS APPOSITA Sargent 
Great Falls, Virginia. This and the following have apparently 
not before been reported from south of Delaware and Pennsylvania. 
CRATAEGUS SMITHII Sargent 
Growing with the preceding. 
Tria Micuauxtir Nutt. 
Along the Potomac River from above Great Falls to below 
Marshall Hall, Virginia, but not before credited to the Washing-
