an that we feel will be distinctly worthwhile
notwithstanding the small size of the nuts. Present varieties of the
so-called northern pecan grown in the northern zone perform erratically
at best and when many of the varieties produce crops the nuts fail to
mature and fill properly.

The Hickory in Indiana

W. B. WARD, _Department of Horticulture, Purdue University, Lafayette,
Ind._

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
