6. Hicoria alba (Linneus) Britton. Wurre Hickory. (Carya 
alba (Linneus) K. Koch). Plate 31. Bark of trunk tight, never 
sealy, fissured, furrows shallow, light gray; twigs at first densely 
hairy, becoming at the end of the season reddish-brown, finally a 
dark gray, remaining more or less pubescent during the season; 
winter buds ovoid, the terminal one at time of fruiting about 12 
mm. (1% inch) long; outer scales broadly ovate and pointed, hairy, 
dark or reddish-brown; leaves fragrant, 2-3.5 dm. (8-14 inches) 
long, main axis hairy; leaflets 5-9, generally 7, sessile or the terminal 
one on a short stalk, oblong-lanceolate to obovate-lanceolate, taper- 
pointed at the apex, hairy when they unfold, becoming at maturity 
firm, smooth and a dark yellow green above, paler or brownish be- 
neath, and remaining more or less densely hairy, especially along the 
veins; fruit subglobose, elliptic, generally about 4 em. (11% inches) 
long, the sutures depressed, husk thick, splitting to the base or 
nearly so; nut globose, or elliptic, rounded at the base, rounded or 
short-pointed at the apex, generally smooth, with the angles ob- 
scure except at the apex; shell thick; kernel sweet. 
Distribution. Southern Ontario south to Florida and west to Texas 
and Kansas. Well distributed throughout Indiana but nowhere 
abundant. In the northern part it is rather rare, becoming more 
or less frequent in the southern part especially in the southwestern 
part. It is generally found in drier situations than the preceding 
species and of the hickories it is the most frequently associated with 
Hicoria glabra (Black Hickory). 
The published records of the distribution are as follows: Cass 
(Benedict and Elrod); Clark (Baird and Taylor) and (Smith); 
Dearborn (Collins); Fountain (Brown); Franklin (Meyncke); Gib- 
son (Schneck); Hamilton (Wilson); Jefferson (Coulter) and (Young); 
Knox (Ridgway); Kosciusko (Clark) and (Scott); Marion (Wilson) ; 
Miami (Gorby); Posey (Schneck); Vigo (Blatchley); Wabash (Ben- 
edict and Elrod). 
Additional records are: Tippecanoe (Coulter); Gibson and Posey 
(Deam). 
Economic uses. Wood and uses similar to that of the shellbark 
hickory. 
7. Hicoria glabra (Miller) Britton. Buack Hickory. Pianut 
Hickory. (Carya glabra (Miller) Spach.) Plate 32. Bark of 
trunk generally a dark gray, varying to nearly black, from whence 
its most common name, fissured, furrows narrow and rather deep 
on old trunks, the ridges rather broad and somewhat scaly on old 
trunks but not flaking off; twigs slender, often hairy at first, becom-
