306. (6) CINCHONA SPECIES. 

 a. Large quills. 



Note. This bark corresponds with specimens of C. pubescens, Vahl., in 

 Howard's collection, but is rather more warty than usual. 



(7) CINCHONA SPECIES. 

 a. Thick quills. 



Note. This specimen is not a true Cinchona bark, but corresponds 

 exactly with Howard's specimens of False red Bark, labelled Bueua 

 Bogotensis, Karst. It is from the woods of f usagasuga, Bogota, Columbia. 



307. Collection of BARKS examined by BATKA, with labels in his hand- 

 writing 'enclosed with the specimens. These labels are in- 

 dicated by inverted commas. 



(1) CINCHONA LANCIFOLIA, Mutis. " China fibrosa, and rubiginosa 



of Bergen, Ba." 



a. Large quilled, pieces, with periderm, of the red variety. 



Note. This specimen does not correspond with Bergen's specimens of. 

 China rubiginosa in this Museum. 



(2) CINCHONA NITIDA, E. et P. " Huanuco bark of my description, 



Ba." 



a. Quills. 



Note. This bark is one of the grey or Huanuco barks of English 

 commerce. It does not occur in Howa'rd's collection. 



(3) CINCHONA SCROBICULATA, Wedd. " Containing Pelletier's aricine, 



Ba." 



a. Flat pieces. 



Note. This is also labelled in pencil, " Quinquina d'Arica ou de 

 Cusco." A mistake of some kind has evidently occurred here, probably 

 from the bark of C. scrobiculata, Wedd., being known as red Cusco bark, 

 and that of C. pubescens, as Cusco bark, since aricine is obtained from 

 the latter, and not from C. scrobiculata, Wedd. 



(4) LARGE CROWN BARK. "Huamalies, of my description, Ba." 



a. Large quills. 



Note. This specimen is also labelled, " Two species, Dr. Reichel." It 

 does not correspond exactly with any others in the museum. Some of 

 the quills are bitter, and in taste resemble the bark of C. micrantha, R. 

 et P. ; others are astringent, with very little bitterness. In other re- 

 spects they resemble the bark of C. officinalis, L. One smaller quill, 

 however, has a short fracture and a very thick silvery layer, and belongs 

 to C. Mutisii, Lamb. 



(5) CROWN BARK FROM VALPARAISO. " Cinchona nova, of my de- 



scription, Ba." 



a. Large quills. 



Note. This bark is a very fibrous red bark, with a periderm extremely 

 cracked, which exfoliates, showing the marks of all the cracks on the 

 surface beneath.
