307. (6) YELLOW BARK FROM PARA. "Para bark, containing Wi id- 

 ler's paricine." 

 a. Large qnills. 



Note. This bark is identical with Martiny's specimen of China de 

 Para pallida. Externally it resembles his China de Bio Janeiro, bat the 

 inner surface is more fibrous. The label is apparently in Batka's writ- 

 ing, bat is not signed by him as in the other labels. 



(7) RED BARK FROM PARA. " Buena hexandra, of my description, 

 Ba." 



a. Large quills. 



Note. This specimen corresponds exactly with Martiny's specimen of 

 China de Bio de Janeiro. Hanbury states that Paricine was obtained by 

 Winkler from Buena hexandra. Pharmacographia, p. 321.
