Boston more abundantly than any other indigenous drug. I 
was a yellowdye of the red Indian, as well as a medicine. Coptis 
trifolia has naturally been more studied than any other species, 
and the rest of the American species more than the rest of the 
Asiatic species. It is not necessary for me to refer to their litera- 
ture so far as it is purely botanic ; but I must do so in regar 
to the Asiatic species, which really are little known, and of which 
more specimens are greatly needed in Herbaria. Franchet in 1897 
wrote a paper on these Asiatic species which was published in 
the Journal de Botanique, wherein he kept them all separate: 
Huth wrote a second one in the Bulletin de lV Herbier Bovssier, 
v, p. 1085: and Finet and Gagnepain have subsequently written 
about the genus. The last paper was published in the Bulletin 
de la Société botanique de France, li, 1904, p. 401, and is re- 
printed as part of their Contributions ad la Flore de I Asie 
orientale, i, 1905, p. 144. They reduce the number of species, 
of Coptis, placing as varieties under Coptis Teeta both C. 
anemonefolia, Sieb. et Zucc. (with C. orientalis, Maxim.), and 
C. chinensis, Franchet.
