Leucadendron, and Mimetes, the others are the same except in some cases- 
for a change of name. For objections raised by Brown as to the namea 
Protea and Leucadeiulron as used by Sahsbury the reader is referred to 
Brown's original essay. 
During the interval elapsing between 1810 and 1856 our knowledge 
of the Order was practically at a standstill. In 1813 Thunberg"*" pub- 
lished, enumerating 80 species of Protea ; another edition f of the same 
work was published in 1818, but with no advance on the former. The 
first authors to take up Brown's genera were Romer and Schultes,| who 
described 167 species of Proteaceae, but omitted the two dioecious genera, 
Aulax and Leucadendron. Although the descriptions are merely copies 
of Brown's and no new localities are given, yet we find here the first 
serious attempt to sweep together the existing synonyms. A third 
edition § of Thunberg's "Flora Capensis," edited by Schultes, appeared 
in 1823, but notwithstanding it was published thirteen years after Brown, 
only the genus Protea with 84 species is mentioned. Two years later 
Sprengel I| published and described 134 species of Proteaceae (33 less- 
than Romer and Schultes), but he included the genera Aulax and Leuca- 
dendron in the Linnaean class Tetrandria monogynia. These two genera^ 
as pointed out above, were omitted by Romer and Schultes. This work 
is not of much importance, as the descriptions are merely compilations 
from Brown. In the following year Nees von Esenbeck 1^ published a 
copy of Brown's essay, and three years later Link gave descriptions of 
2 species of Leucadendron, 3 species of Protea, and 1 species of Serruria, 
An account of the Order Proteaceae with a list of genera by Bartlingff 
appeared in 1830, but is not of much importance. In 1835 Reichenbach ;[ | 
published four coloured plates of Protea with descriptions. This work 
is merely mentioned on account of the plates it contains. An important 
publication was that by Harvey §§ in 1838, who gave a good key to the 
genera based principally on the form of the inflorescence ; two years 
previously the affinities of the Proteaceae were discussed by Lindley.|||| A 
short account of the Order which may be noted was that by Ed. SpachHH
