298. (7) CINCHONA LANCEOLATA, R. et P. (West Coast Carthagena 

 Bark, partly.) 



a. Quills and thick curved pieces. 



Note. This is a variety of Carthagena bark which " comes rid the 

 Pacific." It is described by Pereira under the name of fibrous or spongy 

 Carthagena. Per. Mat. Med., 3rd edition, vol. ii.. pt. ii., p. 1645 ; 

 see Ex. of Pavon's specimens, P. J. [1] , vol. xi., p. 660. Del. et Douch. 

 Quinolog., p. 35, and pi. xiii. It ia very much like the bark of C. 

 lancifolia, but the fibres are looser, and the bitter taste not developed 

 immediately. According to Howard it contains more quinine and less 

 cinchonine than the bark of C. lancifolia. His analysis gives 



Quinine ... 1-17 



Cinchonine ... ... ... ... 0*05 



It is the " Cascarilla lampiiia" of Ruiz. In the vernacular it is known 

 as " Cascarillo bobo, or Amarillo de muna." See Transl. WeddelV* 

 Notei, p. 24. 



(8) C. LANCIFOLIA, Mutis. (New Granada Bark.) 



a. Small flat pieces. 



Note. This specimen is the kind alluded to by Howard as the Calisaya 

 of Santa Fe. P. J. [1] , vol. xi., p. 560. " This kind of bark comes not 

 unfrequently in connection with the bark of C. Palton, and is used for 

 extracting Quinine" (J. E. H.). For fig. of plant, see Bentley and Trimen, 

 Med. Plants, tab. 142. 



b. Varieties from New Granada, in large curved pieces, 



and in quills, without periderm. 



c. Bed variety, in thick curved pieces, with a portion of 



periderm remaining. It " contains cinchonidine as 

 now defined." Red Carthagena bark. 



d. Reddish and inferior variety, in small quills, without 



periderm. 



e. Large quills, with the periderm remaining, and with 



oblique grooves on -the bark caused by some twining 

 plant, a character stated by Pereira to be almost 

 peculiar to this bark. Per. Mat. Med., vol. ii., pt. ii., 

 p. 111. This is the "Coquetta bark of commerce," 

 a name restricted to the orange varieties of C. lanci- 

 folia. C. Palton, C. lanceolata, C. rosulenta, and C. 

 lucunacefolia much resemble C. lancifolia, and are all 

 fibrous barks with a silvery periderm. 



(9) CINCHONA LDCUMJEFOLIA, Pav. (Carthagena Bark, partly.) 



a. Quills with thick white periderm. ( White Grown Bark.) 



b. Flat pieces. " A kind of soft bark. C. lucumsefolia, 



Pav." 



c. Ditto. " C. lucumsefolia, var." 



Note. This bark is very similar in appearance to that of C. lancifolia, 

 but is usually lighter, more loosely fibrous, and of a dullei or more 

 brownish yellow tint. The quills have a very thick, white, silvery and
