The genus Tecoma as founded by Jussieu (Gen. Pl. p. 139) 
was a heterogeneous assemblage of species. The plant 
from which the name of the genus was derived, Tecomazo- 
chitl of Hernandez (Nov. Pl. Hist. p. 408) is almost certainly 
not a member of the Bignoniacew at all; but it has not 
yet been satisfactorily identified, though Dunal (DC. Prodr. 
vol. xiii. pars i. p. 586), refers it to Solandra guttata, with 
the remark that the figure is extremely bad. The other 
Species included in Tecoma by Jussieu were Bignonta stans 
and B. radicans, both having pinnate leaves and a regular 
calyx, and B. pentaphylla, which has digitate leaves and an 
irregularly split calyx. As it was apparent that the 
pinnate- and digitate-leaved species could not be retained 
in the same genus, Bentham and Hooker (Gen, Plant. 
Vol. ii. p. 1044) restricted the name Tecoma to the former. 
Unfortunately, however, Bureau, followed by other con- 
tinental botanists, referred the digitate-leaved species to 
Tecoma, so that much confusion now prevails in the 
nomenclature of the genus. This is accentuated by the
