156 TREES AND SHRUBS. 



Georgia : Columbus, Muscogee County, T. G. Harbison, April 24, 1912 (No. 882, type, young fruit), same locality, C. S. Sar- 

 jent, April 19, 1900 j Waynesborougb, Burke County, C. S. Boynton, September 2, 1902. 

 The specimens, from Columbus agree well in shape and size of the leaves with the type of the species, while those from Waynes- 

 " meter of 12 centimetres, and the branchlets are glabrous. 



Leaves five-lobed, subcordate or nearly truncate at the base, the lobes acuminate and dentate with a few large a 

 acutish or obtuse teeth, rarely nearly entire, at maturity dark green and glabrous above, on the lower surface the veins densely 

 clothed with spreading fulvous hairs, otherwise sparingly villose and glaucous or sometimes glabrescent; petioles densely villose 

 with fulvous hairs.

 1894 ; Funnel Hill, Johnson County, B. F. Bush, October 8, 1912 (No. 6914). Missouri : Campbell, Dunklin County, B. F. Bush,

 Bush, October 14, 1905 (No. 3653), October 11, 1912 (No. 6953). Tennessee : Knoxville, Knox County, C. S. Sargent, Septem- 

 ber 17, 1888. Alabama : Tuscaloosa River, C. Mohr, May 11, 1898; Huntsville, Madison County (cultivated), C. S. Sargent,

This variety is easily distinguished from the type by the more or less dense pale fulvous pubescence of the petioles and of the 

 under surface of the leaves, at least on the veins. The petioles are sometimes glabrous or nearly glabrous, and in none of the 

 specimens seen are they as densely pubescent as in the type specimen. In the specimens from Campbell the leaves of the flower- 

 ing shoots have quite or nearly entire broadly triangular lobes broader than high, the basal lobes often quite or nearly obsolete. 

 By its pubescence this variety approaches Acer Jloridanum Pax ; but is distinguished from it by its larger leaves with long- 

 i lobes, by the larger fruit and the dark color of the trunk. It merges gradually into typical Acer Saccharum Marshall, 

 upy a well denned geographical range. Alfred Rehder.
