13 C. macroca’rra (Vahl, in act. havn. 1. p. 20. t. 3. exclu- 
sive of the synonymes. Lamb. mon. p. 22. t. 3.) leaves broad- 
elliptic, very blunt, densely clothed with rough tomentum be- 
neath, as well as on the branches; calyx entire, with rather pro- 
minent teeth; corolla large, clothed by silky down outside, with 
a bearded limb, and lanceolate segments, which are recurved 
at the apex; genitals inclosed; stigma emarginate; capsule 
pear-shaped, tomentose. h.S. Native of Peru, in the forests 
of Loxa, Guayaquil, and Cuenca; and of New Granada. C.

species nov. Pavon, mss. Called Quina blanca, and Quinguina 
blanc de Santa Fe. Corymbs few-flowered. Calyx urceolate, 
entire. Style furrowed. This species ought not to be con- 
founded with the C. ovalifdlia of Humb., to which it has not the 
least resemblance.

14 C. ogroxciròra (Mutis, mss. Humb. in mag. &c. p.

oblong or cordate, densely clothed with scabrous hairs on both 
surfaces, as well as the branchlets ; panicle brachiate, corym- 
bose, scabrous from hairs ; segments of corolla pilose outside, 
but glabrous inside, linear ; genitals inclosed ; anthers 3 times

S. Native of Peru, in forests in the mountains of Loxa; and of 
New Granada, near Maraquita. H. B. et Kunth, nov. gen. 
amer. 3. p. 401. exclusive of syn. of fl. per. and Ruiz, quinol. 
Called Quina roga and Cinchona vulgo Azahar. Flowers white. 
This is a very distinct plant from C. magnifdlia of Ruiz et Pav. 
It is distinguished from it by its leaves being rounded at the 
base, often cordate, covered on both sides with rough pilose 
tomentum, sometimes the older leaves, however, become nearly 
naked above; the corolla is covered on the outside with bristly 
pilose hairs, while that of C. magnifdlia has short down, and in 
the shape of the capsules. 
Oblong-leaved Cinchona. Tree 12 to 20 feet. 
15 C. macniroria (Ruiz et Pav. fl. per. 2. p. 52. t. 196. but 
not of Humb. et Bonpl.) leaves broad-roundish-oval, naked and 
shining above, and densely clothed with tomentum beneath ; pa- 
nicle brachiate, corymbose, tomentose ; calycine teeth short, acute ; 
corolla clothed with silky tomentum outside, but having the 
limb glabrous above, and the segments lanceolate; anthers in- 
closed ; style exserted; stigma bipartite ; capsules linear, terete.

forests, on the banks of mountain streams, at Chinchao, Cuchero, 
and Chacahuassi. Ruiz et Pavon. C. oblongifolia, Steph. and 
Churchill, med. bot. 4. t. 184. Cascarilla amarilla, Ruiz, quinol.

bark of the shops. Flowers white, sweet-scented. 
Large-leaved Cinchona or Red Peruvian-bark. Tree 40 ft. 
16 C. Pavonu (Lamb. cinch. p. 8.) leaves orbicular or cor- 
date, naked above, but clothed with rusty tomentum beneath, 
as well as the branchlets; corymbs clothed with rusty tomen- 
tum; calyx urceolate, entire, obsoletely denticulated ; tube of 
corolla very long, clothed by silky tomentum outside, with a 
bearded limb; anthers sessile; stigma deeply bipartite ; cap- 
sules very long, terete. h. S. Native of Peru, in the king-

dom of Quito, in groves at Loxa. C. cava, Pavon, mss. 
Called Canela, Corymbs crowded with flowers. Corollas large, 
with ovate-oblong obtuse segments; anthers hardly exserted 
above the throat. Style inclosed ; lobes of stigma linear, obtuse, 
with revolute edges. Capsule length and thickness of a finger. 
This species has considerable affinity with C. macrocdrpa. The 
form of its leaves, the deeply bipartite stigma, its very long 
cylindrical capsules, however, widely separate it.

corolla clothed with silky tomentum on the outside, having the 
limb glabrous above, and the segments linear, acute ; genitals 
inclosed ; stigma bipartite; capsule pear-shaped, hairy, attenu- 
ated at the base. h.S. Native of Peru, on the Andes in 
groves at the river Chilcoplaya. Cascarilla detropa aguda, Ruiz

with pili. Lobes of stigma linear, obtuse.
