 Large trees; bark thick, rather deeply fissured, furrows usually narrow, 

 ridges generally broad and broken into short lengths, the outer bark

 lobes exceedingly variable, the longest lateral lobes are generally near 

 the middle of the leaf, sometimes the lowest pair, sometimes the upper 

 pair are the longest, terminal lobe triangular or oblong, generally widest 

 at the base, although frequently widest at the apex, lateral lobes widest 

 at the base and gradually becoming narrower, towards the apex, rarelj^ 

 somewhat wider at the apex, generally somewhat curved, lobes generallj' 

 sharp-pointed, sometimes wide-angled or rounded at the apex, margins 

 of lobes entire, wavy, toothed or lobed, sinuses wide and rounded at the

Distribution. — New Jersej' and Missouri, south to Florida and west 

 to Texas. The known distribution in Indiana would be that part of the 

 State south of a line drawn from Vincennes to North Madison. It is 

 local except in the southwestern counties. In our area it is found on 

 both high and low ground. In Jefferson and Clark Counties it is found 

 only in the flats where it is associated with beech, sweet gum, pin oak, 

 red maple and black gum. A colony was found iii Washington County 

 on high ground, about eight miles southwest of Salem associated with 

 black and post oak. In Harrison County about two miles southeast 

 of Corj^don it was found on the crest of a ridge with white and black 

 oak. In Daviess Countj^ about four miles east of Washington it is
