‘quina orangé, or orange-coloured Bark. Next to C. Condaminea, 
it is the most efficacious febrifuge of all the kinds of Cinchona; 
the species which M. Mutis, in his Quinologia, calls the Quina 
primitiva directamente febrifuga, because he prefers it to the 
three following species, and because he thinks (what is errone- 
ous, however) the fine Cinchona of Uritusinga is the same species. 
as Quina naranjanda of New Granada. The C. lancifolia has 
smaller leaves than the ethers with tomentose corollas. They are 
also continually smooth, when on the contrary the place of growth 
produces, ae yellow and white: Cinchone, varieties with hairy 
leaves. — 
The Quina ndraayanda loves a rough climate. It grows be- 
tween the 4th and Sth degree north lat. on mountainous decli- 
vities frem 700 to 1500 toises high. The mean temperature of 
this place of growth is about equal with that of Rome. It 
amounts to 13° Reaumur; however the Cinchona trees ascend- 
ing highest towards the summit of the mountains are mostly ex- 
posed to a temperature of from 8° to 9°. During the cold at 
nights, the thermometer falls in these alpine forests for hours as" 
low as the freezing point; however, as far as 1500 toises high no 
snow falls in this latitude. Blaerc : 
The Quina. naranjanda, together ae de C. hie 
longs to the more scarce species, Nature herself has produced 
them in the kingdom of New Granada in a much smaller num- 
ber than those of the yellow and red Cinchone, which latter 
ones form here and there almost. closely-connected shrubberies. 
CC. lancifolia, on the contrary, stands always single; and what 
is to be regretted im so valuable a produce is, that it does not 
‘merease so easily by shoots from the root, a8 thé C. cordifolia and 
. oblongifolia. In the Monographs of Vahl and Lambert, no 
mention is made of the species called Naranjanda of Santa Fe, An
