12. C. acutifolia. Loaves ovate, acute, smooth, the veins of their under side somewhat shaggy ; panicle brachiate, stalked ; corolla silky outside, woolly inside; capsules oblong, tapering to the base, four times as long aa broad. A active of the lower woods of the Andes of Peru, in Chicoplaya. The bark is stated to be called Cascarilla de Hoja Aguda : it is moderately bitter. Ruiz says it does not deserve any attention for medical purposes.
13. C. inicrantha (C. parr(/lora). Leaves broadly oval, blunt, smooth, rather downy underneath at the base of the veins; panicle very large, braehiato, many-flowered ; corollas densely silky ; capsules oblong, three times as long as broad. A species inhabiting the cold elevated parts of the Andes of Peru, especially about the village of San Antonio de Playa Grande ; the inhabitants call its bark Camarillo Fine. The tree is of considerable circumference, flowers in February, land frequently yields eight to ten arrobas of dry bark, sometimes called Cascarilla Provinciana, which differs from that of Huanuco by its decided whitish colour and greater roughness of the surface. It is thicker and more woody, the fracture is more fibrous, and the colour is of a bright cinnamon-brown. A bark, called Pats de Gallinazo, from the numerous specimens of Graphic, a forked sort of Lichen, found on its surface, is yielded by this sort, as well as three others. Reichel considers the samples which Pöppig brought home as undoubtedly belonging to the Huanuco Bark of commerce. Its taste, which is at first acid, becomes afterwards a powerful and permanent bitter. Lindley regards this species as identical with C. scrobiculata.
14. C. glandulifera (C. glandulosa). Leaves ovate-lanceolate ; on the upper aide smooth and shining, with glands at the axila of the veins; on the under aide shaggy, especially upon the principal veins; panicles somewhat corymbose; corolla velvety on the tube, woolly in the inside of the limb ; capsules oblong, three times as long as broad. The flowers are three lines long, and of a pale rose-colour. This tree only inhabits the higher mountains of Peru, and is more scarce than many of the other kinds ; its trunk is from 12 to 15 feet high, and its flowers, in the month of February, fill the forests with their perfume.
On the colder parts of the mountains it becomes a bush, the greatest produce from which is five or aix pounds of bark. It is considered, according to Poppig, one of the finest sorts of Cinchona; he says that the Peruvians distinguish it by its blackish rind, which is only here and there interrupted by small ahagreen spots when in a fresh state. The common people consider these blotches an integral part of the bark,•and look upon it as the more valuable if beneath the larger spots there appears a black shining velvety substance diapersed iu ovals of some lines broad; this is probably caused by some Byasus_ The bark gatherers hence call it Cascarilla Negrilla. When broken, it exhibits a glossy, shining, almost resiny fracture of a ripe orange-colour passing into a fiery-brown. A variety of it, called Case. Provinciana Negrilla, is obtained from the trees growing in warm valleys. According to Mr. Reichal, this bark is equal to the finest sort from Loma, but it is not known in Europe, except in mixture with other kinds.
•• Corollas smooth externally.
15. C. caducifiora (C. magnifolia,liumb.). Leaves oval, smooth, erect, hairy in the sails of the leaves ; panicle brachiate, with corymbose branches ; corolla smooth, falling off very quickly ;'capsules oblong, four times as long as broad. Found near Jaen de Bracamorroa, a hot damp country, where it is called C. bore. The tree is described by Bonpland as being above 100 feet high ; its bark is not employed.
16. C. rosea (C. fusca). Leaves oval, tapering to the base, bluntly acuminate at the point, smooth on each , aide ; panicles clustered, branches corymbose ; corolla smooth on the outside, its limb downy above ; capsules oblong, three time, as long as broad. This occurs not unfrequently about Cuchero, where it forms a highly beautiful tree, which in its size and ramification may be justly compared with the White Beech of Europe. In July it is covered with innumerable pale violet flowers, whence it has obtained the name of Palo de San Juan. Its bark is not collected, but Poppig thinks it would bo found to possess good qualities.
