Carya 605 
’ 
Staminate catkins, scurfy-pubescent, pedunculate in threes at the base of the 
current year’s shoot. Fruit, single or in pairs, very variable in size and shape ; husk 
thin, reddish brown, glandular, opening only at the apex or splitting to the middle 
or to near the base; nut obscurely four-angled ; seed small, light brown, poor in 
flavour. 
Carya microcarpa, Nuttall? (Hicoria microcarpa, Britton *), appears to be only 
distinguished by the nuts, which are very small, compressed and globular. It is 
impossible to say whether it is in cultivation, as all the hickories in England produce 
smaller nuts than they do in America. This form is called by Sargent,’ var. odorata, 
a misleading name, as the tree has apparently no marked odour either in the foliage 
or in the fruit. (A. H.) 
The pignut, which grows usually on dry ridges and hillsides, has a most extensive 
distribution, ranging from Southern Ontario and Southern Maine in the north to 
Florida and Mississippi in the south, and extending westward to Nebraska, Kansas, 
and Texas. 
This species of hickory* seems to succeed fairly well in England, though we 
know of very few trees. The best is at Kew, where there is a fine tree near the 
Temperate House (Plate 172), which is, however, becoming stag-headed. It 
measured, in 1907, 77 feet by 6 feet. It produces fruit abundantly, but the seed, so 
far as we have observed, is infertile. 
Another tree is growing at Leny, near Callander, Perthshire. Though in a 
somewhat exposed situation and at an elevation of several hundred feet, it had a 
stem 3 feet 4 inches in girth and might have been 50 feet high before the leading 
shoot was broken. (H. J. E.)

A tree attaining in America 120 feet in height and 9 feet in girth. Bark grey, 
ultimately separating in plates, which sometimes remain for many years hanging on 
the trunk. Terminal buds, ovoid, obtuse, 3 to 1 inch long, composed of ten to 
twelve imbricated scales; outer scales not deciduous in winter, dark brown, ovate, 
keeled, pointed, tomentose, with scattered glands; inner scales silky pubescent,

in Arb. Am. 68 (1785) as Juglans alba odorata,
