226 ASHE: TREES AND SHRUBS OF WASHINGTON 
TILIA NEGLECTA Spach 
Growing with the preceding but in greater abundance, the 
largest specimens seen being eighteen inches in diameter and sixty 
feet high. Sargent* has recently called attention to this very - 
distinct species, which for several years has been a puzzle, being 
regarded as a probable form of T. Michauxit. 
FRAXINUS CAROLINIANA Mill. 
Along the Potomac River, Virginia, opposite Washington, and 
apparently the northern limit of the species. The species is the 
most characteristic tree in several hundred acres of river swamp, 
but has apparently never been included in the Washington flora.
