3 C. ROTUNDiFotiA (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. fj . 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. 

 Tins 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. OVALIFOLIA (Humb. et Bonpl. pi. equin. 1. p. 65. t. 19. 

 nov. gen. 3. p. 40JJ.) 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 

 bipartite ; capsules oval, constricted at the apex. lj . S. Native 

 of Peru, in the forests of Loxa, in the kingdom of Quito ; Pa- 

 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. ovalifolia of Mutis, 

 the C. macrocarpa of Vahl, or Quinquina blanc of New Granada, 

 which are totally different. 



Oval-leaved Cinchona. Tree 15 to 20 feet. 



5 C. PURPU'REA (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. Pj . S. Native 

 of the lower mountains of the Andes, in forests, at Chinchao, 

 Pati, Muna, Casape, Casapillo, &c. (Pavon) ; and of the Andes 

 of Peru, near the city of Jaen de Bracamoros. C. scrobicu- 

 laris, Humb. et Bonpl. pi. equin. 1. p. 165. t. 47. nov. gen. 

 amer. 3. p. 402. Cascarilla fina Bracamorensium and Cascarilla 

 morada, Ruiz, quinol. p. 67. Cascarilla bobo de hogamorada. 

 Corolla rose coloured. Capsule bisulcate, pubescent when young, 

 but glabrous in the adult state. This is distinguished from the 

 preceding species by its more acute smoother leaves ; by its 

 corymbose panicles ; by its filaments being longer than the an- 

 thers, and their surpassing the throat of the corolla ; by the 

 capsules, which are ovate-oblong, narrowed, and without ribs ; 

 and, lastly, by the shorter and broader lobes of the stigma. 



Purple-fiovfered Cinchona. Tree 40 feet. 



6 C. PUBE'SCENS (V r ahl, in act. havn. 1. p. 19. t. 2. Lamb, 

 mon. t. 2.) leaves broad-ovate, or roundish-ovate, acute, on long 

 petioles, rounded at the base or acutish, naked and shining 

 above, but clothed with pilose tomentum beneath, as well as the 

 branchlets ; panicle brachiate, diffuse, clothed with rusty tomen- 

 tum ; corolla clothed by silky down on the outside, with a 

 bearded limb ; anthers almost sessile ; stigma 2-lobed ; capsule 

 oval-oblong, obsoletely ribbed, tomentose. fj S. Native of 

 Peru, in forests on the lower mountains of the Andes, towards 

 Puzuzo and Panao ; and also of the forests of Huanuco, Ruiz et 

 Pavon. C. ovata, Ruiz et Pav. fl. per. 2. p. 52. t. 195. Cas- 

 canlla pallida, Ruiz, quinol. p. 74. Cascarillo de Pato de Gal- 

 lareta. Petioles 2 inches long. Teeth of calyx very short, 

 acute. Corolla purplish outside and white inside, with ovate 

 obtuse segments. Genitals inclosed. Style exceeding the an- 

 thers. Lobes of stigma ovate. 



Pubescent Cinchona. Tree 30 to 40 feet. 



7 C. MICRA'NTHA (Ruiz et Pav. fl. 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. T? . 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. HUMBOLDTIA'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. Tj . 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.

9 C. GLANDULI'FERA (Ruiz et Pav. fl. per. 3. t. 224.) leaves 

 oval, acutish at both ends, naked and shining above, very pilose 

 beneath, as well as on the branchlets, with undulated rather re- 

 volute margins ; panicle brachiate, very pilose ; corolla pilose 

 outside, with a bearded limb ; calycine teeth very short, mucro- 

 nulate ; segments of corolla ovate ; stigma emarginate ; cap- 

 sules ovate, drooping. Jj . S. Native of Peru, in the kingdom

 in forests in cold elevated places, towards Pillao and Acomayo.

 red. Humboldt and Bonpland have confounded this with the C. 

 cordifolia of Mutis, with which it has not the least resemblance.
