extend also into North America, but in somewhat diminished 
numbers and varieties of form, and have not there diffused them- 
selves generally enough, or far enough northward, or early enough, 
to have spread into temperate Asia. The species are in general 
comparatively local; and none have shown any of the Conyza dis- 
position to become introduced into foreign lands. 
There is a small oriental plant, the Gymnarrhena of Desfon- 
taines, which technically, from its anthers and style, might be 
referred to the Baccharis group of Asteroidex ; but in habit and 
natural affinities, as well as in geographical station, it is so near 
to Geigeria, that we are compelled, as it were, to place it among 
Buphthalmez, although exceptional in what we reckon the most 
essential characters of Inuloidez. 
4. Inuloidee. 
The tribe Inuloidex, not quite so numerous as Asteroidex, is 
more varied, the 1150 to 1200 species being easily distributed 
into 138 genera, or, according to some botanists, nearly double 
that number; and these again may be collected into 9 fairly 
distinct subtribes—Turchonanthee, Plucheinee, Filaginee, Gna- 
phaliee, Angianthee, Relhaniee, Athrixiee, Euinulee, and Buph- 
thalmee, all more or less geographical as well as structural. Asa 
whole, Inuloidez belong for the most part to the Old World, and 
several of the subtribes exclusively so; and the tribe is fairly 
limited (among heterogamous tribes) by the double character of 
style-branches without terminal appendages, and anthers with ap- 
pendiculate or so-called tailed auricles. The exceptional species 
are very few, and the frontier-lines not very difficult to trace, 
although in some measure the subtribe Plucheinex may be said to 
pass into Asteroidex of the Conyza group, Gnaphaliex into Sene- 
cionidez, Euinuleæ into Mutisiacese, and Buphthalme:e into Heli- 
anthoidee. 
Of the above subtribes, the second, third, and fourth, though most 
numerous in the Old World, range also over the New; the other six 
are limited to the Old World. The first and sixth are exclusively 
South-A friean, the fifth almost exclusively Australian, the seventh 
South-African with one or two more northern species, the eighth 
and ninth Afriean, European, and rather more sparingly Asiatic. 
We will take the subtribes, however, rather in their systematic 
than in their geographical sequence, commencing with the tribes
