1913.—In spite of its close bark this tree seems to belong with C. 
ovalis rather than with C. glabra. The bark and the nuts pointed 
at the ends afford the only characters by which it can be distin- 
guished from C. ovalis var. obovalis. 
CARYA OVALIS var. hirsuta, nov. comb.—Hicoria glabra hirsuta - 
Ashe, Notes on hickories. 1896.—This is a common tree on the 
southern Appalachian Mountains of North Carolina at elevations 
of from 1200-1500 m. above the sea, and occasionally grows to a 
height of 20-25 m. with a trunk diameter of 6m. The scaly bark 
of this tree shows its relationship with Carya ovalis rather than with 
C. glabra, and I have taken up AsHE’s name, although the petioles 
and lower surface of the leaflets are not tomentose as he describes 
them, but pubescent, the fascicled hairs which are more or less 
abundant on different individuals being most numerous on the 
under side of the midribs. The fruit is pyriform, usually narrowed 
below into a short stipitate base, 3-4.5 cm. in length, more or less 
compressed, with an involucre tardily dehiscent, usually opening 
only to the middle, and 1.5—3 mm. in thickness. The nut is com- 
pressed, very slightly ridged, and rounded at the ends, with a thin 
shell and a sweet seed. The winter-buds are pubescent, acute or 
obtuse, the terminal varying from 7 to 14 mm. in length. 
Highlands, Macon County, North Carolina, T. G. Harbison, 1913 and 1914 
(no. 1). Harbison no. 1250, June and October 1914, with less pubescence and 
slightly obovoid fruit, with a thin involucre splitting freely to the-base and a 
slightly obovoid nut, appears to be a form connecting the variety with the 
species.

177. 1913.—When I described this species I had not seen terminal 
winter-buds and I mistook it for an Apocarya. Collections made 
later show that the terminal winter-buds are ovate, acute or obtuse, 
and 5-7 mm. long, and that the scales are imbricated and covered 
with close rusty pubescence and more or less thickly with yellow or 
rarely silvery scales. The branchlets are glabrous or pubescent 
during their first winter. Later collections show that the fruit is 
obovoid, gradually narrowed, rounded, and sometimes slightly
