in the order in which the species are enumerated in the 
Prodromus 15, pt. 2 (1866) 717-719. In this article, I 
have followed Mueller’s subgeneric division of FZevea 
into Bisiphonia and Muhevea, now no longer accepted, 
and T have emploved the binomials used by Mueller re- 
gardless of the modern status of these names. This | 
have done so that the following notes will correspond 
with the arrangement of the material in the De Candolle 
Herbarium. In each case, however, I have indicated the 
annotation which [made in June 1950, so that there 
should be no difficulty in finding the present-day equiva- 
lent of the older binomials in those few cases where there 
has been some change. L wish to thank Dr. Charles 
Baechni, Director of the Conservatoire Botanique and 
other members of this institution for their kind help dur- 
ing my visit in June 1950.
