diflora, Ruiz. It isa tree of great beauty, which we have fre~ 
quently seen in deep hot valleys exhibiting its beautiful fragrant 
blossoms. The stamens lie deep and hidden in the tube of the 
corolla; and the fructification is so similar to that of the other 
species of Cinchona, that the Cosmibuena can hardly be admitted 
to constitute a distinct genus. 
On the other hand, it might be advisable to form the Cin- 
chone with long stamina far projecting from the tube of the 
corolla, such as Jacquin’s C. Caribea, Swartz’s C. angustifo— 
lia, C. tn ‘achy carpe , and C. floribunda, into a separate genus. 
nearly allied to Cinchona.. The seven species belonging to it 
possess this peculiarity, that all of them, except one, inhabit 
islands, viz. the Philippine, the West Indian, and the South Sea 
Islands, and that they prefer hot valleys, or even plains, to a high 
mountainous situation. I know but two species upon the South 
American continent which have stamina eaxserta, Lambert’s: 
C. longiflora from French Guiana, and the yet undescribed Cin- 
chona dissimiliflorau, Mut. (staminibus longe exsertis, corolle- 
laciniis tubo longioribus, foliis cordato-oblongis.) which, in the 
kingdom of New Granada, descends from the declivity of the 
mountains towards: the plains as low as 200 toises above the level 
of the sea. C. Caribea and C. angustifolia | are found in the 
West Indies in still lower spots, even in regions which are suf- 
ficiently warm for plantations of sugar canes. All these Island 
Cinchonz with projecting stamens have a smooth corolla. All 
of them have a capitate or obtuse stigma, the C. Philippina* 
alone excepted, which M. Nee discovered at Santa Cruz de la 
Laguna, near Manilla. A divided stigma is, on the contrary, 
bserved in all Cinchone with inclosed stamens. The co- 
rolla of the latter is sometimes smooth, sometimes ny M.
