A species iiitrodiiccd from tropical America and now spontaneous in the 
riiilippines, although not nearly as common as C. caudatus II. B. K. The speci-. 
mens cited by Elmer are certainly Cosmos sulfureus Cav., which we consider to 
be a true Cosmos, and only remotely resemble Coreopsis Drumniondii Torr. & 
Gray.

The type of A. DeCandoUe's genus Sphaeromorphaea is a plant collected in 
southern India by Russel and described by DeCandolle in Deless. Ic. Sel. PI. 
4. t. 49 as 8. Russeliana. In the Prodromns ^ he placed under this species as 
the var. ^ '(jJahrafa, a form collected for or by Boyle in northwestern India, of 
which nothing more is known at present. Under his new genus he included 
fnrther (1) S. petiolaris, a Port Jackson gathering of Gaudichaud*s, which is 
identified by Bentham & Hooker^ with Epaltes australis Lessing, non DC, and 
(2), but doubtfully, Centipcda orhicularis Lour., to which at least in part, belongs 
the material included under Myriogyne minuta Less.* 
In the Genera Plnnfnnim, species one and two of the Prodromus were duly 
reduced to the genera Epaltes Lessing, and Centipeda Loureiro, respectively, but 
5. Russeliana^ the type of the genus, was left undisposed of. It was taken up 
again in the Flora of British India, fresh material having been meantime received 
from central India, collected by the late C. B. Clarke in the Chota Nagpore 
country, S. Russeliana is apparently a species of Epaltes, and manifestly akin 
to E. australis, but distinct from that and probably endemic in the Western
