CINCHONA. 



of the leaves and in the size of the calyx teeth. According to a MS. 

 note of M. Bonpland in Mr. Lambert's herbarium this is the C. land- 

 folia of Mutis ; but Humboldt most positively asserts that species to be 

 identical with the C. angustifolia of Ruiz, which he also considers distinct 

 from C. Condaminea ; and in which he is quite right as will presently 

 appear. 



It is remarkable that R. and P. do not in their published works 

 notice this species, which nevertheless seems to be one of the most 

 common. I presume however that it is the sort which Ruiz, in his 

 unpublished memoir above quoted, calls Cascarilla Chaukarguera, and 

 which he says is not only one of the most valuable kinds, but to which 

 the tradition attaches among the bark gatherers of Loxa, of having 

 been the identical bark sent by the Corregidor Don Francisco Lopez 

 Canizares in 1638 to the Viceroy of Peru the Conde de Chinchon. 



In another place in the same MS. a species is described which is said 

 to be sometimes named Quina Carrasguena, because in the roughness of 

 its quills it resembles the bark of the Carrasca or Qitexido, a sort of 

 Spanish evergreen oak. I know not whether this, which is more 

 generally called Case. CrespUla buena at Loxa, is intended for a sy- 

 nonymeof the Case. Chauharguera, but if the punctuation of the MS. 

 before me may be depended upon, it is to be so understood ; and in that 

 case it is found on the mountains of Cuenca, Loxa, Riobamba, Jaen 

 de Bracamoros, Chacapoyas, Mayobamba, and Caxamarca. This is 

 sometimes made up in cases by itself, but more frequently is mixed 

 with sorts of inferior quality ; Ruiz says it " es una de las Especies 

 mas estimadas en Loxa; y en mi opinion una de las mas activas y 

 eficaces en sus virtudes." There seems no doubt that this species 

 furnishes the Pale Crown or Loxa Bark of English commerce ; or at all 

 events a principal part of it.

Branches quadrangular, smooth except when quite young, at which 

 time they are covered with very short spreading hairs. Leaves oblong- 

 lanceolate, very acute at each end, revolute at the edge ; somewhat 

 coriaceous, not shining, smooth above, thinly covered with hairs on the 

 veins underneath, and not scrobiculate. Peduncles axillary, hairy, 

 3-fid, shorter than the leaves, and not at all forming a panicle or thyrse ; 

 the divisions cymose and about 5-flowered. Calyx-tube tomentose; 

 limb smooth, campanulate, 3-5-toothed, the teeth revolute at the point. 

 (Corolla hairy, the smallest in the genus, with a tube about thrice as 

 long as the cup of the calyx ; the limb spreading, with dense, longish, 

 white hairs. Capsule i an inch long, oblong, narrow, furrowed on each 

 side, smooth, surmounted by an enlarged calyx. R. and P.) I cannot 

 conceive how this most remarkable and distinct species should have 

 been referred to C. lanceolata, nitida, and I know not what others. I 

 have been favoured by Mr. Lambert with dried specimens, which per- 

 fectly agree with the figure above quoted, and which show that it is 

 entirely different from any of those to which it has been referred by one 

 Botanist or another. It has had the credit of furnishing the finest
