Carya Buckley? var. arkansana Sarg. 



7b. Carya ovalis var. obovalis Sarg. This form is probably found 

 throughout the state. It is associated with the species but less frequent. 

 Mass. to Va. and westw. to Mo. 



7c. Carya ovalis var. obovalis f. acuta Sarg. I have this extreme form 

 from Steuben and Wells Counties. The Steuben County specimen is from 

 a native tree in Pokagon State Park and is placed with this form only 

 provisionally. 



7d. Carya ovalis var. obcordata (Muhl.) Sarg. This variety is also 

 probably found throughout the range of the species and with it, but more 

 rarely. 



Rehder gives the distribution as Ont. to Mich. 



7e. Carya ovalis var. obcordata f. vestita Sarg. I collected the type 

 from a tree in Knox County. I also have a specimen from La Porte County 

 which I am calling this form. 



8. Carya pallida (Ashe) Engler & Graebner. Map 765. One or more 

 trees in the Princeton fine sand on the terrace of the Wabash River about 4 

 miles south of Vincennes and half a mile north of the Duncan Siding of the 

 Chicago & Eastern Illinois Railroad. This tree is one of a few hickories 

 and oaks on a narrow strip of land about 100 feet wide on the west of the 

 railroad and east of the adjacent lowland. There are four hickory trees 

 here at this station and I have made complete collections from all but I 

 withhold their names until I can check my specimens by another collection 

 of them. 



N. J. to Ga., westw. to La. and northw. in the Mississippi Valley to Ind. 



9. Carya Buckleyi Durand var. arkansana Sarg. (Bot. Gaz. 66: 24. 

 1918.) Map 766. This hickory so far has been found only in Knox County. 

 I found one tree about 2 miles north of Decker and two trees about 4 miles 

 south of Vincennes in a strip of woods along the railroad just north of 

 the Duncan Siding. 



Knox County. Ind., southw. in the Mississippi Valley to La. and Tex.
