DISTRIBUTION OF TRIBES. 445 
where alone true Verbesine and their immediate connexions are 
indigenous. The nearest slightly diverging genera are Actino- 
meris, nine species, ranging from the Mexican region eastward in 
N. America, only distinguished from Verbesina by the sterility of 
the ray-florets, and Salmea, twelve W.-Indian and Mexican species. 
The Brazilian monotypic Salmiopsis appears to be a connecting 
link between Salmea and some Brazilian Viguiere ; and the above- 
mentioned Mexican Otopappus may also be considered as a diver- 
gent form of Salmea. 
The tropical Wulifia, eight species, and the tropical and Mexi- 
ean Perymenium, ten species, have their nearest connexions pro- 
bably with Wedelia and with Melanthera. 
Gymnolomia, eighteen species, Zaluzania, seven species, and 
Sabazia, eight species, might perhaps be considered as a single 
genus ranging over the Mexiean region, Central America, the W. 
Indies, and Columbia, but not, as far as I am aware, extending 
into E. tropical S. America. The above-mentioned Mexican 
Varilla might perhaps be included with them. Jegeria, six tro- 
pical-A merican species, ranging from Bonaria to Mexico, in some 
respects approaches the same group, being evidently very near 
Sabazia, but really perhaps more nearly connected with Stemma- 
tella and Siegesbeckia, the chief geographical centre of all three 
being apparently the Andine region. 
The West-Indian Borrichia, three species, and Chenocephalus, 
one species, and the tropical-A merican Zrichospira, also monotypic, 
stand each of them isolated as it were in the great subtribe of 
Verbesine. 
There are two genera of the subtribe Coreopside, bordering upon 
Verbesinez, that are limited to tropical Africa (and, indeed, both 
of them have been hitherto observed as indigenous in Abyssinia 
only )}— Guizotia, with three species (one of them spread by culti- 
vation over East India), and Microlecane, one species. The nearest 
connexion of both may be with some of the African forms of 
Coreopsis ; but it is not very close. 
Two Mascarene genera, Micractis, one species, and Epallage, two 
species, evidently belong to Verbesinee ; but I am unable at pre- 
sent to trace out the genera they are most nearly connected 
with. 
The foregoing genera belong to the subtribes Verbesinew and 
Coreopside ; the third subtribe Galinsogee, which I have grouped 
with them, is entirely American. The genera of which it is com-
