species and all of its varieties is the large tree, commonly called in 

 l^orth Carolina red heart or sometimes scaly bark (not shagbark) 

 hickory, and is very common, especially on the red clay soils through 

 the Piedmont. The ample lower leaves frequently have red petioles 

 and the 5 to 7 leaflets are always dotted below with numerous resinous 

 globules, which accounts for its balsmic fragrance in the early 

 spring, hence Marshall's name odorata for this tree. Wangenheim 

 in his ponderous German volume of 1787 has clearly described and 

 figured the form he had before him : Fruit oval, rounded at the base, 

 pointed at the top, the thin husk splitting to the base and freeing the 

 nut, which is slightly oblong and flattened, and angled and pointed at 

 the ends. This is Hicoria microcarpa (iNutt.) Brit. 



H. ovalis ohcordata* n. c. This form has the "fruit subglobose to 

 short oblong or slightly obovate, the nut compressed, broadest above 

 the middle, rounded at base, and usually obcordate at apex." It is 

 frequent esjDecially in the mountains, but is not so common as the 

 preceding. 



H. ovalis odorata\ n. c. This variety according to Dr. Sargent 

 has fruit subglobose, flattened, husk thin, very glandular and split- 

 ting to the base, the nut whitish, thin-shelled, not ridged. This form 

 has also been included under H. microcarpa. 



H. ovalis ohovalisX n. c. This is one of the frequent forms in the 

 State and has the fruit obovate, and the compressed small nut of the 

 same shape. 



H. ovalis megacarpa n. c. Dr. Sargent has described Carya mega- 

 carpa% from material from Rochester, N. Y. He associates with 

 the Rochester form a tree which occurs in the immediate vicinity of 

 the coast from near Beaufort, ]^. C, southward. It is closely re- 

 lated to and probably best regarded as a variety of Hicoria ovalis. 

 This form has extremely large buds, the outer scales of which drop 

 early, stout glabrous bright red-brown twigs ; mostly 5 firm glabrous 

 leaflets thickly dotted beneath with resinous globules and large fig-
