305. (11) NEW SPURIOUS YELLOW BARK, or Orange cinchona of 



Santa I-Y-. 



Note. This specimen agrees well with Howard's specimens of the red 

 variety of G. lancifolia. It appeared in English commerce in April, 1829. 



(12) COQUETTA BARK. 



Nott. This specimen is the typical bark of C. lancifolia, Mutit. It was 

 obtained from Messrs. Isaacs & Samuel, and contains 2J per cent, of 

 quinine. 



(13) Cusco BARK, of English commerce. 



Note. This is the bark of C. scrobiculata, Wedd. It is sometimes 

 called Bed Cnsco bark, to distinguish it from the bark of C. pubescens, 

 Vahl., which is called Cusco or Arica bark. 



(14) RED BARK of English commerce. (C. succirubra, Pao.) 

 Note. This specimen consists of fine flat pieces. 



(15) CINCHONA BICOLOR. Pitoya bark of English commerce. 

 Note. This specimen is identical with Howard's specimen of Steno- 



stomum acutatum. 



(16) CINCHONA NOVA. " Found at a drug mill." 



Note. This bark corresponds exactly with Howard's specimens of 

 Bnena Bogotensis. It is " Mutis's red cinchona of Santa Fe." 



306. Collection of BARKS, presented by DR. LINDLET. 



(1) CASCARILLA COLORADA. (C. pitayensit.) 



a. One large thick quill. (Red Pitaya Bark.) 

 Note. This bark is from the Cinchona forests of Pitaya, province of 

 Popayan, Columbia. It is very bitter, and seems to contain abundance 

 of alkaloids, as the inner surface of the bark sparkles with minute 

 crystals. This, as well as the " Nouveau Calisaya " in Guibourt's col- 

 lection, differs from C. Pitayensis in giving at once a very bitter taste. 



(2) CINCHONA SPECIES. (C. heterophylla and 0. micrantha ?) 



a. Thin flattened quills. 



Note. This specimen appears to consist of two kinds, which resemble 

 the barks of C. heterophylla and C. micrantha in Howard's collection. 

 It was gathered on mountains near Loxa. 



(3) CINCHONA. (C. Mutisii.) 



a. Quills. 

 Note. This specimen is from mountains near Loxa. 



(4) CINCHONA OVATA, R. et P. 



a. Small quills. 

 6. Large quills. 



Note. These specimens are also from mountains near Loxa. They 

 correspond to the C. ovata, R. et P., in Howard's collection. 



(5) CASCARILLA FINA DE URITUSINQA. 



a. Thin curved and twisted flattish pieces. 

 Note. This bark appears to have come from near the root of young 

 plants. It is ticketed, " This is the best and only kind exported." In 

 taste and appearance it corresponds rather with the bark of C. pnbescens, 

 Vahl., than with that of C. officinalis, rar. Uritusinga ; hence there must 

 be some mistake, or perhaps the wrong label has been enclosed with it.
