3 C. RoTUNDIFÒLIA (Pavon, mss. Lamb. cinch. p. 5.) leaves 
roundish, naked above and shining, pilose beneath and on the 
branchlets ; panicle brachiate, pubescent; calycine teeth very 
short; corolla clothed by silky tomentum outside, with a 
bearded limb ; style exserted ; stigma bipartite ; capsule linear, 
terete. h. S. Native of Peru, in the forests of Loxa, in the 
province of Quito. Segments of corolla ovate. Anthers shorter 
than the filaments. Lobes of stigma linear, flat, and obtuse. 
This is a very distinct species, being easily distinguished from 
all its congeners by its narrow cylindrical capsules, and by the 
narrow linear divisions of the stigma. 
Round-leaved Cinchona. Tree 30 to 40 feet. 
4 C. ovatirér1a (Humb. et Bonpl. pl. equin. 1. p. 65. t. 19. 
nov. gen. 3. p. 403.) leaves oval or obovate, naked above and 
shining, but pilose on the veins beneath; calycine teeth ovate, 
acute; corolla clothed by silky tomentum outside, with a 
bearded limb ; anthers twice longer than the filaments; stigma

von; and on the Andes of Peru, near Cuenca; Humboldt and 
Bonpland. Panicle brachiate, pubescent. Flowers white. Seg- 
ments of corolla linear. Lobes of stigma linear, obtuse. This 
Species must not be confounded with the C. ovalifdlia of Mutis, 
the C. macrocarpa of Vahl, or Quinquina blanc of New Granada, 
which are totally different.

5 C. purru'rza (Ruiz et Pav. fl. per. 2. p. 52. t. 193) 
leaves oval or ovate, acute at the apex, and attenuated at the 
base, at length naked on both surfaces and shining; panicle 
corymbose, pubescent ; anthers shorter than the filaments, but 
exceeding the throat; corolla clothed by silky tomentum out- 
side, with a bearded limb; stigma 2-lobed, inclosed ; capsules 
narrow, ovate-oblong, attenuated at the apex. h. S. Native

oo rose coloured. Capsule bisulcate, pubescent when young, 
ut glabrous in the adult state. This is distinguished from the 
eee species by its more acute smoother leaves; by its 
oo panicles ; by its filaments being longer than the an- 
a and their surpassing the throat of the corolla; by the 
psules, which are ovate-oblong, narrowed, and without ribs; 
and, lastly, by the shorter and broader lobes of the stigma. 
urple-flowered Cinchona. Tree 40 feet. 
6 C. puse’scens (Vahl, in act. havn. 1. p. 19. t. 2. Lamb. 
mon. t. 2.) leaves broad-ovate, or roundish-ovate, acute, on long 
Sak rounded at the base or acutish, naked and shining 
T but clothed with pilose tomentum beneath, as well as the 
: anchlets ; panicle brachiate, diffuse, clothed with rusty tomen- 
um ; corolla clothed by silky down on the outside, with a 
Soe limb ; anthers almost sessile ; stigma 2-lobed; capsule 
val-oblong, obsoletely ribbed, tomentose. h.S. Native of 
eru, in forests on the lower mountains of the Andes, towards 
4zuzo and Panao; and also of the forests of Huanuco, Ruiz et

Pubescent Cinchona. Tree 30 to 40 feet. 
7 C. micra’ntna (Ruiz et Pav. fi. per. 2. p. 52. t. 194.) 
leaves broad, oval or obovate, naked and shining above, but 
pilose in the axils of the veins beneath; panicle crowded, pubes- 
cent; anthers shorter than the filaments, hardly exserted; style 
very short; stigma 2-lobed; capsule elliptic, attenuated at the 
apex. h.S. Native of the Andes of Peru, in cold elevated 
forests towards St. Antonio de Playa Grande, where it was first 
observed by John Tafalla. Corolla clothed with silky down on 
the outside, with a bearded limb, and ovate segments. Calycine 
teeth very short, acute. Lobes of stigma ovate. Capsule bisul- 
cate, ribless. This species has some affinity with C. Condami- 
nea , but its small flowers, and elliptical ribless capsules, together 
with its very short style, and other marks, readily distinguish it. 
Small-flowered Cinchona. ‘Tree 20 to 30 feet. 
8 C. Humeotpria‘na (Lamb, cinch. p. 7.) leaves lanceolate, 
acute at both ends, naked above, but villous beneath, as well as 
on the branchlets; panicle glomerate, villous; calycine teeth 
very short, acute ; corolla clothed by silky down outside, with 
a bearded limb; anthers sessile, inclosed; stigma exserted, 
emarginate; capsules ovate, hairy, glomerate. kh.S. Native 
of Peru, in the kingdom of Quito, in forests near the town of 
Jaen de Bracamoros. Pavon. This is a strongly marked and 
very distinct species; there is none with which it can be con- 
founded; it is the C. villosa, Pavon, mss.
