This tree is near the northeast corner of Alumni Lawn, near the sidewalk that comes from Alumni Hall.

Both swamp chestnut oak and swamp white oak trees are found naturally in wetlands.  They both have leaves similar to chinkapin oak: shallow rounded lobes (or large rounded teeth) and lower leaf surfaces that appear whitish and may be hairy.  The primary difference in the leaves are in the number of veins.  Swamp chestnut oak leaves usually have 9 or more pairs of veins that extend to the lobes, while swamp white oak leaves have 5 to 8 pairs of veins with not all extending to the tips of the lobes. 

If acorns are available, the two species are fairly easily distinguished.  Swamp chestnut oak acorns have short peduncles (stalks) while swamp white oak acorns have very long peduncles.  This individual produces acorns - the swamp white oak trees elsewhere in the arboretum have not been observed to produce acorns.
