America, “ yalvulis minus extrorsum diyergentibus et recepta= 
tulo ovato nec lineari seminumque margine integro nec lacero.” 
But except the smooth unindented coat of the seed wings, which 
I mostly find, the remaining forms of the fruits exhibit grada- 
tions, which link together, as it were, all the Cinchonz. For 
the new genus of Island-Cinchone, delighting in hot plains, 
there would consequently remain: corolla glabra, filamentis 
longe exsertis ex basi tubi nascentibus. Semina margine integro 
emcta. Stigma simplex capitatum. But 1°, Many Cinchonze 
stamimibus inclusis, and C. grandifiora Ruiz, have corollam 
glabram. 2°. C. Phillippina has far projecting filaments, stig- 
ma bilamellatum, and yet, as it appears, semina margine integro 
cmceta. 3°. C. excelsa has stigma subeapitatum leviter emargi- 
natum, the seed not indented, and the filaments not projecting. 
Under these exceptions, it would certainly be bold to separate 
tribes of plants so nearly allied. — SoeS ois. 
The singular prickly C. spinosa of St. Domingo appears at 
first sight to belong least to the genus Cinchona. It is wonder- 
fully small-leaved, and has frequently folia terna verticillata. 
Another prickly Cinchona differs still more in colour from the 
genuine Cinchona bark trees; it grows near Guayaquil, on the 
coast of the Pacific, and M. Tafalla showed it to us in the winter 
of 1803, during our stay there. This undescribed ‘Species is a 
creeper, and-on that account in some measure related to the genus — 
Danais trom Madagascar, which Persoon ranks next iM succession 
to the Portlandia, since the Pedeira fragrans, more resembling 
the Cinchona, has been separate from Pedeira fetida. This new 
C. scandens of Tafalla has in other respects the complete fructi- 
fication of the ague-curing Cinchona, and belongs indisputably to 
the most remarkable phenomena of the physiognomy of plants. __ 
The very same fruit of the genuine Cinchona is also produced
