70 THE VOYACxE OF H.M.S. CHALLENGER. 



COMPOSITE. 



In consequence of different botanists having employed the same specific names for two 

 or more diverse plants, the synonymy of the St Helena Composite has been involved in 

 great confusion, and therefore it maybe useful to publish Burchell's manuscript tabulation 

 of the synonymy deduced from a comparison of his unrivalled collection with the older 

 collections in the British Museum. It will be seen from a comparison with our final 

 synonymy that De Caudolle mistook one or two of the plants which had previously been 

 described under other names. Another cause of confusion was the transposition by 

 Burchell himself of his numbers 154 and 157. That he did so is evident from the 

 numbers attached to his specimens, and the names and numbers on his drawings of the 

 two plants in the Kew Herbarium Library. With the exception of this emendation we 

 print Burchell's manuscript verbatim, adding in brackets the names adopted in this work.
