I take much pleasure in associating with this plant the name of Charles 

 Clemon Deam, State Forester of Indiana, who for many years has industriously 

 studied the trees of Indiana. 



Persea pubescens (Pursh) Sargent. — The first varietal name 

 pubescens of Pursh (18 14) was taken up for this tree in The Silva 

 of North America (7:7. 1895); but under the rules adopted by the 

 Vienna Congress the first specific name must be used, and this is 

 paliistris {Tamala palustris Rafinesque, Fl. Tellur. 137. 1838), and 

 Persea pubescens (Pursh) Sargent should become P. palustris 

 (Rafinesque) Sargent. 



Platanus occidentalis L. — The leaves of the northern plane 

 tree are broadly ovate, 3-5-lobed by broad shallow sinuses rounded 

 in the bottom, cordate or truncate at base, becoming glabrous 

 except on the under side of the midrib and principal veins, the 

 lobes broad, acuminate, serrate-toothed with long straight or 

 curved remote acuminate teeth. Individual trees with leaves 

 cuneate at base may be distinguished as 



Platanus occidentalis f. attenuata, n. f. — Dift'ering from the 

 type in the long cuneate base of the usually less deeply lobed 

 leaves.
