298. (19) CINCHONA SCROBICULATA, Wedd. (Red Cusao Baric.) 

 Far. 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 Pern. 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 ronge matrons of Gui- 

 bourt." " The flat bark was also imported as Galisaya." (J. E. H.) 



Far. ft. DELONDRIANA, Wedd. (Spurious Calisaya.) 

 a. Flat pieces. 



Note. This bark most resembles flat Calisaya bark, but has not such 

 distinct digital farrows, 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. 5-3. 



(20) CINCHONA SDCCIRUBRA, Pav. (Red Bark.) 



a. Flat pieces, " grown in the shade." 



b. Large quilled pieces, "grown in snnshine." 



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 mnch paler than ordinary red bark, and is difficult to distinguish from 

 Calisaya quill. Its taste is astringent and extremely bitter. Bed bark 

 may be recognised by its red colour and the presence of numerous warts 

 on its surface. For fig. of plant, see Bentl. dt Trim., Med. Plant*, tab. 140. 



(21) CINCHONA TDCOJENSIS, 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) BDENA BOGOTENSIS, Karsten. (False Red 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 Drag. Hi., 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.
