Concerning the differentiation of Catalpa speciosa vs. C.
Godfrey & Wooten (1988) treat only C. bignoniodes for N
Fla, GA and adjacent Alkabama--which may be of some interest to
Jerome. They include no mention of C. speciosa as a synonym, so we
may presume that these authors consider C. speciosa outside the area.
What we have in SC is a mish-mash of both, and they do seem to
intergrade a bit. Somebody needs to figure out if the caterpillars
that feed on C. bignoniodes will also eat C. speciosa--maybe there is
some biochemistry here that could separate them.
Duncan & Duncan (1988) treat both trees for the SEUS...and
provide a key separating them.
