normal inflorescence ; Eriocephalus, seventeen species, with some 
of the characters of the distant American subtribes Melampodinex 
and Ambrosiex; and Lasiospermum, four species, with the densely 
woolly achenes of some Arctotideze. 
The Cotulec form a rather more distinct group of Anthemidee ; 
and, geographically, they have been so long and so widely dispersed 
as to have established local genera or subgenera in very distant 
regions. Generally they belong to the southern hemisphere, and 
are mostly extratropical; but a few range over the temperate 
regions of the northern hemisphere of the Old World, or are 
within the tropics of both the Old and the New. They are gene- 
rally small annuals or dwarf prostrate perennials with small 
capitula, the involueral bracts nearly equal in about two rows, the 
female florets usually numerous, with short, regular or irregular 
corollas, not strictly ligulate, and sometimes very much reduced 
or entirely wanting. Cotula itself, with about forty species, has 
the wide range of the whole group; it has been variously subdi- 
vided into sections or distinct genera, without any of them (except 
when monotypical) having any distinct. geographical area. Wa- 
nanthea, the only allied genus exclusively northern, consists of a 
single species from the mountains of Corsica, showing some 
approach to the Chrysanthema and other Anthemidex of the 
same Mediterranean region. The slightly diverging genus Cenia, 
eight species, and Otochlamys, a single species, are limited to South 
Africa.  Centipeda, three species, is more tropical in the Old 
World, although in America it is only in the southern extratro- 
pical regions. Plagiocheilus, six species, is limited to extratropical 
or Andine South America; so would also be Soliva (four species ?) 
but for one of them which has established itself in Australia, and 
another in Portugal and South Carolina, perhaps as ancient, pos- 
sibly as more modern colonists. Abrotanella is yet more southern, 
ranging from Antarctic America to New Zealand and the southern 
mountains of Australia. The three remaining monotypic genera, 
Ceratogyne, Elachanthus, and Isoetopsis, all from extratropical 
Australia, are somewhat anomalous in their styles and some other 
structural characters, but can scarcely be so well placed in any 
other tribe, and certain!y with none having similar geographical 
connexions.
