perfectly. One Arséne specimen at P even has remains of fruits that connect the Hartweg and 
Ehrenberg collections. It is not obvious how Allen (1945) was able to put together Ehrenberg and 
Hartweg collections and did not find a connection between these and Arséne's. 
Standley (1922) did realize that P. pachypoda and O. benthamiana were conspecific. 
Buthis preference for the combination Phoebe pachypoda over P. benthamiana was in some way 
unfortunate, since type material of Persea pachypoda is now scarce and fragmentary, and does 
not have flowers. On the other hand, type material of Oreodaphne benthamiana is present with 
good specimens in several herbaria, and it does have flowers. Type locality of P. pachypoda was 
established on the data supplied by Mc Vaugh (1970) in the introduction to Bentham's "Plantae 
Hartwegianae" reprint.
