myristicaeffirmis, Britt. ( Carya myristicwfdrmis, 

 Nutt.). NuTMEG-HiCKOKY. Tree, to 100 ft. with dark 

 brown bark, broken into appres.sed scales: If ts. 5-11. 

 short-stalked or almost sessile, ovate-lanceolate, the 

 uppermost much larger and oborate, serrate, scurfy-pu- 

 bescent beneath when young and with brown scales 

 above, at length dark green above, silvery and lustrous

 generally solitary, shortovoid orobovate, about IK in. 

 long; nut ovoid, reddish brown marked with irregular 

 spots and stripes, thick-shelled, 4-celled below; kernel 

 sweet. From S. Car. to Ark. and Mex. S.S. 7:342^3.- 

 A very decorative species on account of its handsome 

 foliage, but not hardy North. 



BB. Ifut usually as broad as long, compressed with 

 irregularly angled or reticulate surface, thitt- 

 sheiled, 4-celled below : kernel bitter. 



aqudtica, Britt. (Carya aqudtica, Nutt.). Watek- 

 Hickory. Bitter Pecan. Usually small tree, rarely to 

 100 ft., with light brown bark separating into long, thin 

 plates. Ifts 7-13, sessile or short-stalked, lanceolate, 

 long-acuminate, finely serrate, yellowish tomentose when 

 young, glabrous at length, fr. 3^, ovoid to broadly obo- 

 vate, 1-lHin. long; husk thin, splitting to the base; 

 nut obovate, much compressed, irregularly angled and 

 ridged, dull reddish brown; kernel very bitter. From 

 Va. to 111., south to Pla. and Tex. S.S. 7:344-45. 

 U.S.N.C. 12, 7-8. 



minima, Britt. {Carya anidra, Nutt.). Bitter Nut. 

 SwAsip-HiCKORY. Tree, to 100 ft. : bark grayish brown, 

 broken into thin scales: young branches and petioles 

 glabrous: Ifts. 5-9, ovate-lanceolate to lanceolate-acumi- 

 nate, densely serrate, pubescent when young and glan- 

 dular, almost glabrous at length, 3-6 in. long : fr. 2-3, 

 broadly obovate or subglobose, winged from the apex to 

 the middle, ?4-l?^ in. long ; husk thin, splitting some- 

 what below themiddle; nut slightly compressed, round- 

 ish, abruptly contracted into a short point, irregularly

 Hicoria glabra. 



reticulate; kernel bitter. Quebec to Minn., south to 

 Fla. and Tex. S.S. 7:340-11. Em. 226. -A valuable 

 park tree, with handsome, rather broad head, growing 

 in cult, more rapidly than other Hickories.

glabra, Britt. ((7arj/«porc!na, Nutt.). Pignut. Figs. 

 1061, 1062. Tree, occasionally to 120 ft., with usually

 splitting mostly only half way to the base; nut usually 

 brownish, not angled ; kernel mostly astringent. S.S.

 some park tree, with rather narrow-oblong 

 head and slender, often pendulous branch- 

 lets, especially in the following var. A very 

 variable tree, and the following varieties 

 are considered by some botanists as dis- 

 tinct species. 



Var. microcirpa, Trel. (Carya micro-

 or less shaggy: Ifts. quite glabrous, often
