The very considerable size of the trees of this species, and its large membranous leaves, covered on the under side with prominent violet coloured veins, are said by Poppig to mark it readily. The bark, called Cascarilla Bobs Colorada, is not in much esteem • but as it is readily collected it can be sold at a low price, and is used for adulterating other sorts. According to Reichel it is undoubtedly the Huamala Bark of trade. Dr. Lindley regards this and the foregoing species as identical.
6. C. macroce/yx. Leaves ovate, roundish, hardly acute, quite smooth on both sides ; their principal veins close together ; panicles coryinbose; corolla slightly downy externally, with the lobes hairy on the upper side ; limb of the calyx smooth, bell-shaped, acutely 5-toothed. A species distinguished by De Candolle by the above characters, but only known to him from specimens. It is found on the mountains of Peru. Nothing is known of its sensible properties.
7. C. Ilumbohltiana (C. oralifolia, lionpland). Leaves oval, rather obtuse, on the upper side /shining, on the under between silky and downy; panicle, brachiate, 4-flowered; silky the outside, smooth in the throat, with its lobes shaggy inside at. the point ; capsules ovate, longitudinally ribbed, about twice as long as broad. First described by Bouplend as identical with C. ovalifolia of the ' Flora Peruvians,' but afterwards recognised by him aa distinct. It forms forests in the province of Cuenca in Peru. In commerce It is called Cascarilla Peluda, which signifies Velvet-Leaved Quinn. Its bark is not in much estimation ; it is however a good deal collected for mixing with other sorts, and Bonpland suspects it to be of good quality.
8. C. rnagnifolia (C. baucens ; C. grandifolia ; C. oblongifolia). Leaves broadly oval, somewhat acuminate, smooth ; principal veins of the under side shaggy at the edges; panicle brachiate; corollas silky externally; capsules oblong, tapering, seven times as long as broad According to Ruiz, Humboldt, and De Condone, the C. oblongifolio of Mutis, which produces the Red Bark of Santa F6 is identical will the C. or for do Azahar, of the 'Flora Peruvians.' The former grows In 5' N. lat., at the height of from 3600 to 7800 feel above the sea, and is particularly common about Mariquita; the latter occurs in the hottest parts of the Andes of Peru, about 10 degrees south of the line. C. oblongifolia of Santa F6 produces a bark which,
although less efficacious than that of C. Condaminea and C. laneifolia, is nevertheless better than that of C. pubescent; but this is hardly reconcilable with Poppies statement that the C. magnifolia has woody bark, not very astringent, and is chiefly used for purposes of adulteration : he adds, that the bark-peelers do not even reckon it a fever bark, or Cascarilla, but name it simply Corteza del Azahar. This last-mentioned author describes the tree as very stately, with unusually large white flowers, diffusing a delicious odour like that of orange-blossoms; possibly the differences adverted to are the result of climate.
9. C. viacrocarpa (C. ovalifolia, Mutis). Leaves elliptical, leathery, on the upper side perfectly smooth, on the under between hirsute and pubescent ; panicle trichotomous; corollas with closely pressed down on the outside ; the lobes hairy inside ; capsules cylindrical, twice as long as broad. The White Bark of Santa F6. The tree grows between 3° and 6° N. lat., at heights between 4200 and 8400 feet. A variety of it, with leaves quite smooth on both sides, is common near Santa Martha.
10. C. crastifolia. Leaves oblong, rather blunt, tapered to thcbaee, leathery, smooth on each side; when young shaggy in the tails of the veins ; stipules membranous, grown together; corymbs terminal, trichotomous; branches 2-edged, few-flowered; fruit oval-oblong, three times as long as broad, crowned by the calyx. Found about Quito and Loxe ; distinguished from C. otacrocarpa by its peculiar membranous stipules. Nothing is known of its bark.
11. C. dichotorna. Leaves oblong-lanceolate, smooth, when first unfolding rather silky; peduncles terminal, dichotomous, in loose few-flowered corymba; capsules linear, cyliudrical, slender, fourteen times longer than broad. Found on the Andes of Peru, in groves near Pueblo-Nuevo, in the district of Chicoplaya. Its bark is described as brown, intensely bitter, with a little acidity. This and the foregoing species Dr. Lindley places with those imperfectly known.
