quishes; preserving its signification, however, for 
the purpose of distinguishing a subdivision of Ge- 
nera ; because these very remarkable plants s£ill 
remain anomalous; ; and iri that 1nanner, still re- 
quire an isolated post. 
fter this, in the year 1812, in an appendix to 
the author's Synopsis Plantarum Succulentarum, 
three more genera were removed from Sax?fraga, 
and some new species enumerated. And it was 
moreover there announced, that more species 
would eventually recede in the shape of new ge- 
nera, from the old Genus ; the result of which se- 
paration will gradually develop itself in the fol- 
lowing pages. The new generic names there given, 
have been carefully constructed from the most uni- 
versal features; and always iu the feminine gender 
of Saxifraga ; for the especial purpose of prevent- 
ing any orthographical alteration in the specific 
names of the plants, on their elevation to genera; 
except only in the instances of. Miscopetalum and. 
Hirculus ; the former of which was printed before 
the idea occurred, and the latter remaining (ac- 
cording to the laws of Linneus) as an ancient.

. lt will in all probability be the opinion of 
some Botanists, that too many new genera are 
here made out of the old Genus Saxifraga, and 
from discrepancies too often resulting from Aabit, 
and tco seldom from character ; and consequently : 
sometimes uanecessarily introduced, The author
