He moreoversuspects it to be identical with the Quina AmarUla of Huamalies,but he judged merely from a comparison of the barks, having no Botanicalspecimens of that kind; and must have been wrong, becausePoppig has proved the Huamalies bark to be obtained from C. pubescens.Bergen says that what is called in commerce Dark Ash bark,False Loxa, or Dark Ten Cinchona agrees with samples of this from thecollection of Ruiz.833.

Leavesoval-lanceolate, obtuse, coriaceous, shining, rather revolute at the edges,without any trace of pits on the under side ; gradually narrowing intorather a long petiole. Peduncles axillary, corymbose, longer than theleaves, rather spreading, but often stiffj forming a large open thyrse.Calyx with a campanulate limb, having 5 shallow triangular teeth.Corolla tomentose, except at the base which is nearly smooth, with thetube 3 times as long as the tube of the calyx the limb shaggy inside.;Seven good specimens in Mr. Lambert's herbarium, and 5 in that ofDr. Thomson show that this is a perfectly distinct plant, althoughconfounded by the former with C. Condaminea, from which it differs inthe smoothness of all its parts, the large cupped calyx, with shallowteeth, and the obtuse laurel-like leaves destitute of all traces of scrobiculi.One of the specimens in Mr. Lambert's herbarium is marked" vulgo Cascarilla e&toposa." This is no doubt the Cascarilla hoja deLucma mentioned but not described in Ruiz's MSS. ; nothing is said ofits quality he ; places itamong those which furnish the Quina fina deLoxa.834.

Leaves nearlysmooth at all periods of their growth, usually very exactly elliptical andacute at each end, sometimes more oblong, occasionally roundish-oblongand obtuse or almost cordate at the base ;of a coriaceous texture, veryglossy on the upper side, as much so as a common laurel; with ratherprominent veins which are either hairy or smooth on the underside, andusually hairy at the axils, but very slightly scrobiculate there, if atall ; petioles smooth, or sometimes downy when young, from % to fathe length of the leaf. Peduncles panicled, corymbose, hardly longerthan the upper leaves, to which they are axillary, forming a close compactthyrse, covered with a short thick down. Tube of the calyxdowny like the pedicels limb ; campanulate, shining, and almost alwayssmooth, with acute or even acuminate triangular teeth. Tube of thecorolla cylindrical, tomentose, about 3 times as long as the tube of thecalyx; limb very shaggy internally. Fifteen specimens in Mr. Lambert'sherbarium, and 18 in that of Dr. Thomson, have supplied theforegoing description.
