CINCHONACE.S. 



pale bark of commerce. But Ruiz in his MSS. asserts that it cannot be 

 compared for good qualities with finer kinds of Loxa Bark. He more- 

 over suspects it to be identical with the Quina AmarUla of Huamalies, 

 but he judged merely from a comparison of the barks, having no Bota- 

 nical specimens of that kind; and must have been wrong, because 

 Poppig has proved the Huamalies bark to be obtained from C. pube- 

 scens. Bergen says that what is called in commerce Dark Ash bark, 

 False Loxa, or Dark Ten Cinchona agrees with samples of this from the 

 collection of Ruiz.

Loxa in Peru. Pavon. 



Every part of the plant quite smooth except the corolla. Leaves 

 oval-lanceolate, obtuse, coriaceous, shining, rather revolute at the edges, 

 without any trace of pits on the under side ; gradually narrowing into 

 rather a long petiole. Peduncles axillary, corymbose, longer than the 

 leaves, rather spreading, but stiffj often 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 the 

 tube 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 of 

 Dr. Thomson show that this is a perfectly distinct plant, although 

 confounded by the former with C. Condaminea, from which it differs in 

 the smoothness of all its parts, the large cupped calyx, with shallow 

 teeth, and the obtuse laurel-like leaves destitute of all traces of scrobi- 

 culi. One of the specimens in Mr. Lambert's herbarium is marked 

 " vulgo Cascarilla e&toposa." This is no doubt the Cascarilla hoja de 

 Lucma mentioned but not described in Ruiz's MSS. ; nothing is said of 

 its quality ; he places it among those which furnish the Quina fina de 

 Loxa. 



834. C. lanceolata FL Peruv. ii. 51. iii. t.223. Cascarillo 

 lampino Ruiz quinol. 64. Cold elevated mountainous situa- 

 tions in groves on the Andes, in the districts of Muna, Panas, 

 Pillao and Cuchero R. and P. At the distance of 15 or 20 

 leagues from the city of Huanuco Ruiz MSS. Bolivia. 



Twigs quite smooth as high as the inflorescence. Leaves nearly 

 smooth at all periods of their growth, usually very exactly elliptical and 

 acute at each end, sometimes more oblong, occasionally roundish-oblong 

 and obtuse or almost cordate at the base ; of a coriaceous texture, very 

 glossy on the upper side, as much so as a common laurel; with rather 

 prominent veins which are either hairy or smooth on the underside, and 

 usually hairy at the axils, but very slightly scrobiculate there, if at 

 all ; petioles smooth, or sometimes downy when young, from % to fa 

 the length of the leaf. Peduncles panicled, corymbose, hardly longer 

 than the upper leaves, to which they are axillary, forming a close com- 

 pact thyrse, covered with a short thick down. Tube of the calyx 

 downy like the pedicels ; limb campanulate, shining, and almost always 

 smooth, with acute or even acuminate triangular teeth. Tube of the 

 corolla cylindrical, tomentose, about 3 times as long as the tube of the 

 calyx; limb very shaggy internally. Fifteen specimens in Mr. Lam- 

 bert's herbarium, and 18 in that of Dr. Thomson, have supplied the 

 foregoing description. If the most ordinary attention is paid to the 

 distinctive characters of the species of this genus, C. lanceolata cannot
