5. Hicoria microcarpa (Nuttall) Britton. (Carya microcarpa 
Nuttall.) Plate 30. Bark fissured and rather tight on the trunk 
near the base, becoming more or less shaggy a short distance above 
the ground, the lower part of the trunk resembling that of Hicoria 
glabra (Black Hickory), the upper part that of Hicoria ovata (Shell- 
bark Hickory); twigs slender, becoming at the end of the season 
smooth, reddish-brown; winter buds ovoid, the terminal one at 
fruiting time 6-10 mm. (about 14 inch) long; scales densely covered 
with small yellow scales, more or less pubescent especially along 
the margins, the outer usually almost glabrous, blunt or the outer 
somewhat sharp-pointed; leaves 2-3 dm. (8-12 inches) long, main 
axis at maturity smooth or nearly so; leaflets 3-7, usually 5, oval to 
oblong-elliptic, the lateral ones sessile, the terminal one _ short- 
stalked, long taper-pointed, at maturity light green and smooth 
above, paler and smooth beneath or with some pubescence in the 
axils of the veins and on the veins; fruit subglobose er obovoid, 
densely covered with yellow scales, sutures elevated; husk thin, 
about 1.5 mm. (1/16 inch) thick, somewhat tardily splitting to 
nearly the base; nut oval, somewhat angular, sharp-pointed at each 
end, about 1.5 em. (1% inch) long, about as wide through the widest 
diameter, compressed; shell thin; kernel sweet. In the northern 
part of the State a form is found with a nut about one-fourth longer 
in diameter, obovoid, nearly smooth, rounded at both ends or ob- 
cordate at the apex. Another form was noted associated with the 
two forms above, with bud scales and twigs very pubescent, husk 
of fruit about one-third thicker, and shell of nut as thick as Hicoria 
ovata. 
Distribution. Massachusetts west to Michigan and south to 
Missouri and Georgia. More or less frequent throughout Indiana 
and associated with Hicoria ovata. The habitat and range of this 
species has not been well studied. 
The published records of the distribution are as follows: Clark 
(Baird and Taylor); Delaware, Jay, Randolph and Wayne (Phinney); 
Franklin (Meyncke); Gibson (Ridgway). and (Schneck); Hamilton 
(Wilson); Jefferson (Coulter) and (Young); Knox (Ridgway); Kos- 
ciusko (Scott); Marion (Wilson); Miami (Gorby); Posey (Schneck). 
Additional records are: Posey (MacDougal and Wright); ‘lippe 
eanoe (Coulter); Laporte, Vermillion, Warren and Wells (Deam) 
Economic uses. Wood and uses same as that of the shellbark 
hickories.
