    298. (19) Cinchona scrobioulata, Wedd. (Bed Gusco Bark.) Var. a. Gbnuina. a. Flat pieces. b. Long quills. Note.—This bark is the Cascarilla colorada del Cuzco and the Cascarilla colorada de Santa Anna, of Peru. The quills came mixed with quilled Calisaya bark, which they much resemble ; they are usually, however, thinner and more involute than those of Calisaya, and have a redder fracture. They are identical with the Loxa rouge marrons of Gui- bourt. The flat bark was also imported as Calisaya. (J. E. H.) Var. /3. Delondriana, Wedd. (Spurious Calisaya.) a. Flat pieces. Note.—This bark most resembles flat Calisaya bark, but has not such distinct digital furrows, is less compact, and has a redder tint than that bark. P. J. [1], vol. xiv., p. 82 ; [1], vol ix., p. 268. For fig. of this bark see Wedd. Nat.Hist. Quinq., tab. 28, f. 5-8. (20) Cinchona succirubra, Pav. (Bed Bark.) a. Flat pieces, grown in the shade. b. Large quilled pieces, grown in sunshine. c. Small quills, from Ceylon, 1873. d. Inferior red bark, 1873, Rouge pale. Note.—This is the Cascarilla colorada of the natives, and specimen c is much paler than ordinary red bark, and is difficult to distinguish from Calisaya quill. Its taste is astringent and extremely bitter. Eed bark may be recognised by its red colour and the presence of numerous warts on its surface. For fig. of plant, see Bentl. db Trim., Med. Plants, tab. 140. (21) Cinchona Tucujensis, Karsten. (Maracaibo Bark.) a. Flat pieces. Note.—This bark occurs in thin more or less twisted pieces, with a coarse fibre and a surface which resembles that of C. cordifolia in being- rough, but the surface is not so purple as in that bark, and the taste is not earthy, but somewhat aromatic. See P. J. [1], vol. x., p. 348 ; [1], vol. xiv., p. 167. FALSE CINCHONA BARKS. (22) Buena Bogotensis, Karsten. (False Bed Bark.) a. Thick quilled pieces. b. Smaller ditto. Note.—This bark is the Cinchona oblongifolia of Mutis, but not the Cascarilla magnifolia of Lamb. It answers well to the description given under Quinquina nova in Hist, des Drog. iii., p. 183. It was mistaken by Humboldt and others for true red bark. See Howard, Nueva Quin. art. Cinchona magnifolia, p. 5. The outer surface is usually smooth, of a dark purplish brown colour, and has transverse cracks, evidently caused by desiccation. The pieces are thick and heavy ; the taste is astringent, but scarcely bitter. For fig. of bark see Del. et Bouch. Quin., pi. xxiii., the two left-hand figures. P
