 Economic uses. Wood and uses the same as the preceding. 



5. Hicoria microcarpa (Nuttall) Britton. {Gary a 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 34 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 or 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 cm. (}/(? 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 ova^.a. 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); '1 ippe 

 canoe (Coulter); Laporte, Vermillion, Warren and Wells 'Peam) 



Economic uses. Wood and uses same as that of the shellbark 

 hickories.
