in the style, and generally in habit, involucres, and other 
minor characters, and in a more northern geographical distri- 
bution. They have some outward resemblance to some American 
Asteroide of the Solidago group (Haplopappus inuloides, Chry- 
sopsis, &c.), but with very different styles and anthers and a 
wide geographical severance, and are rather more nearly con- 
nected in structure and station with a few genera of Mutisi- 
aces, amongst which one genus (Printzia) has been recently 
placed; but their real affinity, structural and geographical, and 
therefore presumedly genetic, is with Athrixiee onthe one hand 
and Buphthalmee on the other. They belong exclusively to 
Europe, Asia, and Africa; their chief centre appears to be the 
great Mediterranean and Oriental region; but they extend south- 
ward into South Africa, where they have established a few small 
local genera, and eastward to the tropical and subtropical extreme 
east of Asia, although not enough to the north-east to have 
passed into North America. In Asia they may be said to be par- 
tially replaced by allied Mutisiaceous genera; and the South- 
African genus Printzia, five species, has been, as above-mentioned, 
hitherto actually referred to Mutisiace:, although without the 
essential characters of that tribe, and to our eyes having a close 
affinity with the Inuloid genus Jphiona. Neither in Australia 
nor in America is there any genus of Euinulex, nor yet of any 
nearly allied Mutisiacew. The North-west American Luina, with 
a deceptive aspect of some species of Inula, proves, when examined, 
to be as different in structure as the Znula-like Asteroidew above 
mentioned, but in this instance to belong to Senecionide:ze. 
Of the separate genera, the two principal ones above mentioned, 
Inula and Pulicaria, range generally over the greater part of the 
area of the subtribe, and are, besides the two species of the Me- 
diterranean Jasonia, which may almost be regarded as a section 
of Inula, the only ones which extend to Europe. The next nume- 
rous genus, /phiona (12 species), has still a wide range from the 
Levant to east tropical and South Africa. Codonocephalum and 
Amblyocarpum, two nearly allied monotypic genera, are limited to 
the Levant; Grantia, with four species, is in that region and in 
Algeria. Allagopappus and Vierea, both monotypic, belong to 
the Canary Islands, where are also some rather peculiar species of 
Inula. Vicoa, with five species, is more tropical both in Asia and 
Africa. Calostephane and Porphyrostemma, both monotypic, are 
also tropical, but African only.  Pegolettia has one tropical and
