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. landfoliaof Mutis but Humboldt most;positively asserts that species to beidentical with the C. angustifolia of Ruiz, which he also considers distinctfrom C. Condaminea ; and in which he is quite right as will presentlyappear.It is remarkable that R. and P. do not in their published worksnotice this species, which nevertheless seems to be one of the mostcommon. I presume however that it is the sort which Ruiz, in hisunpublished memoir above quoted, calls Cascarilla Chaukarguera, andwhich he says is not only one of the most valuable kinds, but to whichthe tradition attaches among the bark gatherers of Loxa, of havingbeen the identical bark sent by the Corregidor Don Francisco LopezCanizares in 1638 to the Viceroy of Peru the Conde de Chinchon.In another placein the same MS. a species is described which is saidto be sometimes named Quina Carrasguena, because in the roughness ofits quillsit resembles the bark of the Carrasca or Qitexido, a sort ofSpanish evergreen oak. I know not whether this, which is moregenerally called Case. CrespUla buena at Loxa, is intended for a synonymeofthe Case. Chauharguera, but if the punctuation of the MS.before me may be depended upon, it is to be so understood ;and in thatcase it is found on the mountains of Cuenca, Loxa, Riobamba, Jaende Bracamoros, Chacapoyas, Mayobamba, and Caxamarca. This issometimes made up in cases by itself, but more frequently is mixedwith sorts of inferior quality ;Ruiz " says it es una de las Especiesmas estimadas en Loxa; y en mi opinion una de las mas activas yeficaces en sus virtudes." There seems no doubt that this speciesfurnishes the Pale Crown or Loxa Bark of English commerce ;or at allevents a principal part of it.2. Limb of the corolla stupose. Leaves not scrobiculate.832.

I cannotconceive how this most remarkable and distinct species should havebeen referred to C. lanceolata, nitida, and I know not what others. Ihave been favoured by Mr. Lambert with dried specimens, which perfectlyagree with the figure above quoted, and which show that it isentirely different from any of those to which it has been referred by oneBotanist or another. It has had the credit of furnishing the finest415
