FLOWERING PLANTS AND FERNS OF INDIANA. 829 



for interior finish and flooring; it is also largely employed in ship- 

 building. "Curled Maple" and "Bird's-eye Maple" of cabinet- 

 makers are varieties. 



Flowers in February. March and April. 



Its distribution is so general that specific reference to stations 

 is omitted. 



A. nigrum Michx. Black Sugar Maple. 



(A. aaccharinum nigrum T. and G.) 



Sparingly distributed throughout the State along streams, and 

 in low. rich lands in central and southern Indiana. Usually in 

 lower ground than the preceding, and more closely confined to 

 bottom lands. The wood is similar to that of the Sugar Maple, 

 the sap also yielding much sugar. 



Flowers in April and May.

 (MacDougal): Hamilton and Marion (Wilson); Gibson and Posey 

 (Bidgwav). 



A. Negundo L. Box Elder. Ash leaved Maple. 

 (^Xegundo aceroides Moench.) 



Fairly distributed through the southern counties of the State 

 on wet banks, becoming more rare northward, except in the 

 prairie regions where it has been largely planted for a windbreak. 

 The light wood is of no great value, although somewhat used in 

 interior finish and for paper pulp. Locally largely used for sap 

 troughs. Cultivated as an ornamental tree in all parts of the 

 State. 



Flowers as early as April and as late as July.

HIPPOCASTANACE.E. Buckeye Family. 



.ESCFLUS L. 



M. Hippoca8TANum L. Horse Chestnut. 



A handsome tree cultivated for ornament which in a few 1 

 seems to have escaped from cultivation. I know of three in- 

 stances in which these escapes have successfully held their own 

 for over ten years. While not common save under cultivation, 

 the species has undoubtedly obtained a foothold in the State.
