304. (11) QUINQUINA BLANC DE LOXA. (No. xxxvii., p. 153.) 



a. Quills. (C- dectirrentifolia, Pav., Planchon, p. 179, 



note 1.) 



Note. This bark closely resembles Howard's specimens of C. Mutisii, 

 Lamb. 



(12) QUINQUINA BLANC FIBREUX DE JAEN. (No. xxxviii., p. 153.) 

 Note. This specimen consists of pieces which differ in taste and 



structure. One piece evidently belongs to G. lancifolia, ilutis, and 

 another to G. pubescens, Vahl. It is labelled in Howard's writing, 

 " Gascarilla con hojas de Zambo," which is the vernacular name for 

 Cinchona palalba, Pav. To this species the rest of the pieces may per- 

 haps belong. 



FALSE CINCHONA BARKS. 



(13) QUINQUINA NOVA COLORADA. (No. xlviii., p. 164.) 



a. Quills. 



Note. This is the bark alluded to on p. 164, as found in commerce in 

 1825. The periderm is like the Bio de Janeiro bark (Buena Bogotensis, 

 Kant.). .But when the periderm is removed, the surface beneath is seen 

 to be wrinkled longitudinally, not fissured transversely. 



b. Quills. From Rio de Janeiro. 



Note. This agrees exactly with Howard's specimen of Buena Bogoten- 

 sis, Karst. See p. 166, 1. c. 



(14) ECORCE DE PARAGUATAN. (No. liii., p. 167.) 



a. In short, thick, twisted pieces. 



Note. This bark is identical with Howard's specimen of Condaminea 

 tinctoria, to which species it is referred in Hitt. des Drog., 6 6d., 

 t. iii., p. 184, but it is thicker and older, and has lost its periderm. 



(15) QUINQUINA BLANC DE MUTIS. (No. liv., p. 167.) 



a. In short flat pieces. 



Note. This bark is referred by Planchon to Cascarilla macrocarpa of 

 Weddell. This specimen differs from Howard's in having the periderm 

 removed. 



(16) COSTUS AMER. (No. Iviii., p. 170.) 



Note. There is no other specimen in the Museum of this bark. It is 

 in pale brown fragments, which have a slight resemblance to Cusparia 

 bark. 



(17) QUINQUINA CARAIBE. (No. Ixii., p. 173.) 



Note . This agrees well with the other specimen from Guibourt. It is 

 the bark of Exostemma Caribaeum, 12. et Sch. See Hist, dei Drog., C"" 

 fd., t. iii., p. 189. 



(18) EXOSTEMMA DU PEROU. (No. Ixiii., p. 174.) 



Note. This is exactly similar to the other specimen from Guibourt. 



(19) MALANEA RACEMOSA, L'Herminier. (No. Ixv., p. 175.) 

 Note. This is a thin bark, and is like that of Stenostomum acutatr.zn 



in Howard's collection, but is not dark internally like that bark. It seems 

 to me to be identical with a specimen of the bark of Steuostomum men- 

 tioned below.
