flowered rather high climber in forest, Toledo, 27 May 1907, M. E. 
Peck 919 (rype in Gray Herb.). — A true congener of B. unguis- 
cati L., to which, with B. exoleta Vell., the genus Bignonia is re- 
stricted by Schumann. It agrees with B. exoleta, as described by 
Bureau & Schumann, in its crispate calyx but differs in the pu- 
bescence, entire leaflets, and solitary or twin flowers. From %- 
unguis-cati, a more variable plant than has generally been realized, 
it differs essentially in the crisped calyx margin and leaves per- 
manently pubescent beneath. The West Indian and South 
American material of B. unguis-cati examined is mostly glabrous, 
the Mexican and Central American finely puberulous on petioles, 
etc., at least when young, and good characters for varietal sepa- 
ration will doubtless be found when the species is carefully studied. 
Certain specimens, such as H. H. Smith 1134 from Colombia, 
simulate B. dasyonyx in pubescence, but have the entire calyx of 
'B. unguis-cati. The former may prove to be only a variety of the 
latter species, but no real evidence of this is afforded by the material 
at hand.
