depressed at apex, narrowed below into a short stipelike base, occa- 
sionally slightly winged at the sutures, sometimes roughened by 
prominent reticulate ridges, puberulous and covered with small 
yellow scales, 2-3.5 cm. long and 2-2.5 cm. in diameter; the 
involucre is 2-3 mm. in thickness, splitting to the base by usually 
2 or 3 sutures. The nut is pale or reddish, subglobose, and not 
more than t.5 cm. in diameter, or ovate, acute at base, narrowed 
and rounded at apex, slightly compressed, or rarely oblong and 
acute at base, rounded at apex, and 2.5-3 cm. long and 2 cm. 
wide; the shell varies from 2-3 mm. in thickness; the cotyledons 
are sweet. 
Although the fruit and thin branchlets of C. floridana resemble those of 
the glabra-ovoidea group, the thick rusty pubescence on the young leaves and 
branchlets separates it from all the plants of this group. It differs from them 
also and from other hickories in the occasional appearance of the aments of 
staminate flowers from the axils of leaves, and in the fact that it is often shrubby 
in habit and produces large crops of fruit on stems not more than 2-3 m. high. 
The sessile, or nearly sessile, terminal leaflet is also unusual in the genus. 
Carya floridana is common on the eastern coast of Florida, growing on dry 
sandy ridges and low hills from Valusia County southward to Jupiter Island, 
Palm Beach County. It is common, too, usually as a small shrub near Orlando 
in Orange County and southward to De Soto County, and occurs on the shore 
of Pensacola Bay. 
THE TEXAS HICKORY.—In 1860 BuCKLEY described his Carya 
texana in Proc. Philad. Acad. As the name was otherwise occupied 
Duranp changed it to C. Buckleyi, and as BucKLEY described the 
fruit as globose with a thin involucre C. Buckleyi has been adopted 
for a tree with globose fruit, a thin involucre, and pale red nearly 
globose nuts. This tree with the round nuts is common in the 
neighborhood of Denison, Grayson County; it grows also near 
Jacksonville in Cherokee County, at San Augustine, San Augustine 
County, and at North Pleasanton, Atascosa County, and in Okla- 
homa on dry sandy hills west of Muskogee, Muskogee County. 
The hickory with obovoid or ovoid fruit, often with an involucre 
varying greatly in thickness, and with an oblong or slightly obovoid 
compressed slightly angled pale nut, which I described as C. arkan- 
sana (Trees and Shrubs 2:203. pl. 181),is much more common and 
more widely distributed in Texas, and it is probable that BUCKLEY
