dendron, E. Br., is Leucadendron, Berg. In passing the various descrip- 
tions and plates which appeared at odd times in the Botanical Magazine 
and the Botanical Begister may be noted. 
The writer had been paying some attention to the South African 
Proteacege, and in 1910 undertook to monograph the Order for the "Flora 
Capensis." A vast amount of material had accumulated since Meisner's 
work appeared in 1856, a large percentage of which was new. Descrip- 
tions of new species have appeared in various numbers of the Kew 
Bidletin, and a description of a new genus will be found in the same 
publication. The genus Diastella, Salisb.," has been taken out of 
Mimetes, E. Br., where it was placed by Meisner and given a generic 
status ; Orothamnus, Pappe, will also be kept as a distinct genus. The 
separation of Mimetes as recognised by Meisner into the three genera 
Mi7netes, E. Br., Diastella, Salisb., and Orothammis, Pappe, and the 
establishing of the new genus Spatallopsis, Philhps,! brings up the 
number of the South African genera of Proteaceae to 13. 
In conclusion, and as a short summary of what has been said above, 
we find that there are four distinct stages in the advance of our know- 
ledge of the South African Proteaceae. The first was Boerhaave's publica- 
tion in 1820, a serious beginning to the systematic work on the Order. 
Next followed Linnaeus, who put systematic botany on a firm basis by the 
introduction of his binomial nomenclature. Salisbury and Brown mark 
a very distinct advance, as it was only then that the genera came to be 
recognised, and lastly it is due to Meisner, who enlarged on Brown and 
brought together all which had been published by previous authors, that 
our present knowledge of the Order is what it is to-day. 
The writer takes this opportunity of thanking Dr. Otto Stapf, F.E.S., 
for kindly help which was given in looking up references in the older 
hterature.
