CINCHONACEJE.the pedicels. Peduncles corymbose, in the axils of the upper leaves,forming rather a small thyrse. Calyx with a tomentose tube; the limbcampanulate, smooth, 5-toothed : teeth triangular, acute. I have seenno fully expanded corolla ;but it appears to be like that of C. lanceolata,This is certainly a very different species from C. lanceolata, withwhich it is associated by M. De Candolle, and from C. Condaminea towhich Mr. Lambert unites it. The figure in the Flora Peruviana is excellent.I have examined 6 indifferent specimens in Mr. Lambert'sherbarium ; it does not occur in Dr. Thomson's collection. According toRuiz this is considered in the provinces of Huanuco, Tarma, Huamalies,and Xauxa, to be the best of all the barks and it fetched in his timethe highest price it is ;called Cascarillo or Quino fino, the same nameas is given to C. vricrantha bark, and several others.Po'ppig has a bark called Case, hoja de Oliva, which he believes to beproduced by this, aud of which he speaks thus": This kind of barkis only known in small quantities, and is not regularly collected. Itresembles the finest kinds of Loxa bark, and excels them in the resinousand astringent flavour. The tree itself, which is unknown to me, growsonly upon the coldest mountains, and is said to have a stem scarcely 8feet high, straight, and producing very little bark, but which is so highlyesteemed, that the viceroy and corregidores purchase it all, to send aspresents to the king and the grandees of Spain, so that it is never seenin commerce* The flower is of a bright red, covered with a whitetomentum inside, and expands in May." This bark has been describedby Ruiz in the Quinologia, but he did not recognise it as belonging toC. nitida, and it is very doubtful whether it is produced by that species.831. C. Condaminea Humb. and i.Bonpl pi. ceq. 33. t. 10.Quinaquina Condam. in act. par. 1738 Near Loxa in themountains of Cajanuma-Uritucinga, and in those of Boqueron,Villonaco and Monje; it is also found near Guancabamba andAyavaca in Peru. It always grows on micaceous schist, andrises as high as 7500 feet above the level of the sea, first appearingat the elevation of 5700 feet ; so that it occupies a zoneof 1 800 feet. Humboldt.Twigs quite smooth as high as the inflorescence. Leaves quitesmooth at all periods of their growth, usually ovate-lanceolate, occasionallynarrower and only lanceolate, in some specimens ovate; of arather thin texture, not at all shining on the upper side, or but little soin some specimens ;furnished almost always at the axils of the veinsunderneath when full grown, with a pit or scrobicula, which is eithernaked or ciliated, but when young indistinctly scrobiculate, or not atall. Petioles smooth, about the length of the leaves; stipules oblong,obtuse, membranous, smooth. Peduncles panicled, corymbose, in theaxils of the upper leaves, forming a large loose thyrse, covered with athick short down. Tube of the calyx downy like the pedicels ;limbvery shortly urceolate, 5-toothed, pubescent, not shining ;with theteeth roundish-triangular, acute. Tube of the corolla slender, about fourtimes as long as the tube of the calyx, tomentose; limb very shaggyinternally. Of this I have examined 6 specimens in Mr. Lambert'sherbarium, and 15 in that of Dr. Thomson ; many of them very fineones. They all correspond in having a very short downy limb to thecalyx, and a loose inflorescence, but they vary a good deal in the form414
