252 BOTANICAL GAZETTE [SEPTEMBER 
branchlets are slender, pubescent during their first year and puberu- 
lous in their second season. The winter-buds are covered with 
rusty brown pubescence and yellow scales, and often furnished 
near the apex with the tufts of white hairs, which are generally 
found on the buds of Carya Buckleyi. The fruits on trees in other 
parts of the state vary from obovoid to ellipsoidal, or are rarely 
subglobose; they vary from 1.5 to 3 cm. in length, and are nearly 
cylindrical or much compressed; the involucre varies from 1 to 
4 mm. in thickness, and on some trees the fruit is completely cov- 
ered by the yellow scales. On some trees the branchlets lose their 
pubescence early and by the end of September are glabrous, red, 
and lustrous.
