Leaflet distance is another facet of the hickory leaf that allow you to recognize those of one coinage from those of another . The leaflets at the end of the rachis , the one away from where the rachis attaches to the outgrowth , are typically larger than those closest to the ramification . The " odd - man - out " growing at the end of the rachis is ordinarily the big . consider a few hickories for leaflet size , the folder of the swamp hickory vary in duration from between 2 inches long to 5 in long , tell the " National Audubon Society Field Guide to Trees . " Black hickories leaflets can attain lengths of 6 in , while those of the mockernut hickory may be as foresightful as 8 inches .
Leaflet Numbers
The identification number of leaflets growing on a hickory leaf ’s rachis is an important key in describe the species . Some hickory have as few as five leaflets on this centralize stalk , let in shagbark and shellbark hickory . Others have as many as 11 or 13 , such as bitternut hickory and water hickory respectively .
