| Notes: | Note source: No photo. Label source: No 84 Peruviana 1867. Close dense powder. The precipitate from acid solution waxy brown liquor. Cinchona nitida is found under No. 66 of the barks marked C. nitida Flora Peruviana esbuena del Peru. The specimen in th, e collection of Pavon is grey bark of fine quality v different from any vars of condaminea. It is not as dense , but more resinous, the outer coat is more even, and does not present the varieties of surface in the latter bark. The periderm is on the whole, adherent; but where it separates from the derm it peels off in flakes and leaves a brown indented surface. The internal surface is yellowish red near cinnamin colour. I t is classed by Guibourt as red bark under No. X1 Quinquina rouge de Lima. The colour, of the bark verges on the reddish tint, and the difficulty in isolation of alkaloid of commercial red bark is also present in this species. Guibourt says that by uncompleted analysis he found this bark rich in cinchonine and quinine. I confirm this view, and have obtained about 0.571 quinine, 0.142 quinidine crystallised, and 1.4 cinchonine - total 2.113 %. The quinine however is in a state that makes it difficult to crystallise in salts, contrasting with the species C. condaminea with which this tree has, been identified by some observers. Moreover our term 'grey', as given to the bark on account of the lichens which cover it, is but an imperfect translation of the ? which implies the aspect of a head silvered over with ???. | ||||
