Y'dhl, at the end of the second part of his ^ Symb. Bot.' has 

 shown that A. opobalsamum was described by Linnaeus^ not 

 from specimens, but from a bad figure, and that it is not distinct 

 from A, gileadensis. What Balsamea meccanensis, Gled., in 

 \Act. Soc. Nat. Cur. Ber.' iii. p. 127. t. 3. f. 2., may be, I have 

 no means of determining. DeCandoUe refers it as a variety 

 with bipinnate leaves to the present species ; but if it belongs 

 to this genus, that structure must have arisen either from ac- 

 cident or cultivation, and in neither case can be considered as 

 a permanent form. 



Brown has about twenty years ago shown that the Linnaean 

 genus Exacum ought to be limited to the East Indian species 

 which have all showy flow^ers ; it is therefore somewhat 

 strange, that in almost all the European Floras, those of Britain 

 not excepted, that name is given to small slender filiform 

 plants, with an appearance quite different from the typical 

 species. To the European species Adanson had long since 

 given the name Cicendia ; they differ from Exacum by the 

 funnel-shaped corolla, the segments of w hich become twisted 

 after flowering into a kind of calyptra above the capsule.
