Although obliged to adopt a new specific name for this 
very interesting plant, I strongly suspect it to be the same 
as Codonanthus Africana, Don, in the idea that this latter has 
been described from memory, and that its supposed opposite 
bsagittate 
leaves are attributed to it by mistake, and the su 
ractes are nothing more than the external sepals of the plant 
here figured. At all events, I have hardly any doubt that 
this is a real Codonanthus ; and it will not be unnecessary tO — 
complete or correct, according to its structure, what the 
original generic character leaves doubtful or erroneous. The 
essential characters of Codonanthus may stand as follows: | 
Caly# 5-phyllus, foliolis externis cordatc-ovatis, multo majo- 
ribus, internas occultantibus. Corolla tubuloso-urceolata, _ 
tubo brevissimo, limbo apice quinquelobo, lobis brevibus 
obtusissimis, estivatione plicatis, vix contortis. Stamina5, 
apice tubi corolle (brevissimi) inserta, inclusa, antheris 
oblongis, bilocularibus, rimis longitudinalibus 2 dehiscenti- 
bus, estivatione inversis. Ovarium ovatum, basi disco an- 
nulari adnato cinctum, incomplete biloculare, ovulis e bast 
loculi cujusque 2, erectis, anatropis, semiseptis oppositis: 
Styli 2, ineequales, interne longe concreti. Stigmata capitata. ae
