Mr. Charles C. Deam, forester, naturalist and botanist, in his book "Trees of Indiana," revised 1952, lists seven distinct types of hickory in the state and nine sub species. As Deam is approaching his 87th year (August 30), he makes this statement: "I thought I knew trees, and hickories especially, but at this time when I can hardly see and write I find there is a great need for reclassification." What is true in Indiana is no doubt true in other areas where _Hicoria_ grows--each year new seedlings and hybrids are found that just step out of any previous description and a new tree may result or change the published data. Some trees develop five leaflets, while others have seven and nine leaflets. The bark may be smooth, rough, scaly, or shag. The nuts will vary in size and form with a thin to quite thick shell. This, of course, applies to the seedlings as the grafted or budded varieties vary only with the location, season, and growing conditions. The present classification, according to Deam, is as follows: 1. _Carya pecan_--Pecan. 2. _C. cordiformis_--Bitternut. 3. _C. ovata_--Shagbark and 2 sub species--_fraxinifolia_ and _nuttali_. 4. _C. laciniosa_--Bigleaf Shagbark (Shellbark). 5. _C. tomentosa (alba)_--Mockernut--one sub species. 6. _C. glabra_--Pignut and sub species--Black Hickory. 7. _C. ovalis_--Small-Fruited Hickory and 5 sub species. 8. _C. pallida_ } 9. _C. buckleyi_ } --Minor species of lesser importance. The hickory species thrive in Indiana, doing very well in all sections except in certain portions of the northwestern part of the state and on muck or sandy soils. The tree loves company or does well alone. When the hickory stands alone, the trees are well formed and make a good specimen tree. Many hickory trees are found growing in the river bottom land from Central to Southern Indiana with fewer trees found north of a line extending from Terre Haute through Indianapolis to Richmond. This southern area also contains the largest population of pecans. There are some woods that contain only pecan trees while a mile or so away no pecans are found but all are hickories and occasionally some woods contain both pecan and hickory. The trees in the woods areas, many of which seem to be the same species, produce a wide variety of fruits. When the trees are more closely examined there is a difference in the bark, the branch, the leaf, pubescence, shape of nut and shell structure. As there are all seedling trees in this particular woods, several outstanding trees have been checked and especially as to cracking qualities of the nuts. At harvest time a hammer is part of the equipment and the nuts are cracked at the tree and the tree marked for discard or further consideration. Future Possibilities of the Hickory
