This genus, which is allied to Herpestes and Spherotheca, 
but abundantly distinct from them and the other genera of 
the tribe, I have named after Dr. Ildefonso Gomez, a 
talented physician of Rio de Janeiro, who has devoted much 
of his leisure time to the investigation of the botany of his 
native country, and to whom I am indebted for great kind- 
ness during my last visit to Rio. In the first edition of 
Steudel's Nomenclator Botanicus, there is an Iidefonsia of 
Schott, evidently named after the same individual, but it is 
not taken up in the last edition.

Josepha augusta. Vellozo Fl. Flum. 4. t. 16. 
Has. On bushy hills, at Jurujuba Bay. P Aug. Sep. ; 
I have met with at least two species of this genus in 
Brazil, besides the present. One of them is very similar to it 
in habit, a large shrub with a peculiarly straggling habit, but 
its leaves are almost glabrous, narrower, and of a less coria- 
ceous texture than those of B. spectabilis. The flowers are 
also of a paler colour. The other is a very distinct species,
