Hi Len

Yes there is an oak which name is almost Chinkapin namely, Chinquapin
and also called yellow chestnut oak, the latin name "Quercus
muehlenbergii", and there is also a dwarf Chiquapin oak,
"Quercus prinoides".

However the Chinkapin, Florida, Ozark and Allegheny Chinkapins, are in
the chestnut group, "Castanea", like the American chestnut, "Castanea
dentata".

And not related to the horsechestnut, like the Ohio buckeye, or the
yellow or red buckeye, "Aesculus pavia" etc.
