surface, full and rounded at the ends, and usually pubescent; the 

 lower leaves often of 7 very large tomentose leaflets. It occurs 

 through the Southern States from eastern Xorth Carolina to Missouri, 

 usually at low altitudes and in the larger river swamps. Another 

 variety, H. ovida Jiolmesiana n. c. was proposed as Hicoria holme- 

 sia7ia* and was described as being smooth, having smaller fruit 

 2.3-3 cm. in diameter, smaller than the type. It was based on material 

 from Xew England, the type coming from Mt. Tom. This form seems 

 to be pubescent as well as glabrate. It occurs in Xorth Carolina only 

 in the higher mountains. A smaller tree in !North Carolina than the 

 common shagbark, it has only five smaller and usually less pubescent 

 leaflets, and smaller subglobose fruit and nut ; buds and twigs glab- 

 rate or pubescent but scarcely larger than those of the Carolina shag- 

 bark. This was originally proposed as a species and may be such. 

 Another form which should be looked for in the western portion of the 

 State and particularly in the mountains is H. ovala fraxinifoUa n. c. 

 (C. var. Sarg. : T. & S. 2: 207. 1913). This has five very narrow 

 leaflets, orange-brown twigs, and a thick spongy husk which is very 

 rugose when dry. 



Hicoria aistralis n. c. (Cari/a Ashe, Bui. Ch. Mus. 14; 12). 

 This shagbark occurs on the edges of swamps in the coastal plain south 

 of Sampson County. It is a slender tree, 80 to 100 feet in height, 

 about 2 feet in diameter, with bark scaly in long strips, and is closely 

 related to the Carolina shagbark, being, when foliage is mature, essen- 

 tially glabrous throughout, indudimj the fruit, but is every way 

 larger and stouter; twigs, buds, fruit, nuts, and leaflets which are 

 broadly lancelate and sharply serrate, those of the Carolina shagbark 

 l)eing mucli narrower. The fruit is glabrous, sulcate, and slightly 

 impressed at each end. 



Varieties of Hicoria ovat.is (Wang.) n. c.f Dr. Sargent re- 

 gards oralis as being the oldest specific name applicable to this hick- 

 ory, forms of wliich have been called microcarpa and odorafa. This
