15. C. angustifolia Swartz. 
16. C. brachycarpa Vahl. 
These six latter species grow all in the West-India Islands, 
and love a temperature of from 17 to 22 degrees R. 
eee 8f corymbifera Forster. 
Native of the Friendly Islands. 
18. C. Philippica, discovered near Manilla by Nec. 
I do not venture to assert that all Cinchone hitherto known 
are comprehended within the eighteen species arranged here. I 
have merely wished to enumerate those which are known to me, 
partly in their natural state partly from good figures, and which 
to me appear indisputably specific from each other. C. acuti- 
folia, C. micrantha, C. glandulifera, C. dichotoma, COC Cosmi- 
buena) acuminata, and C. spinosa, deserve a closer investigation. 
The genus might perhaps increase to twenty-four species.
