A species introduced from tropical America and now spontaneous in the 
Philippines, although not nearly as common as C. caudatns 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 Drummondii Torr. & 
Gray.

The type of A. DeCandolle’s genus Sphaeromorphaea is a plant collected in 
southern India by Russel and • described by DeCandolle in Deless. Ic. Sel. PI. 
4. t. 1/9 as S. Russeliana. In the Prodromus 6 he placed under this species as 
the var. (3 glabrata, a form collected for or by Royle in northwestern India, of 
which nothing more is known at present. Under his new genus he included 
further (1) 8. petiolaris, a Port Jackson gathering of Gaudicliaud’s, which is 
identified by Benthanr & Hooker 7 with Epaltes australis Lessing, non DO., and 
(2), but doubtfully, Centipeda orbicularis Lour., to, which at least in part, belongs 
the material included under Myriogyne minuta Less. 8 
In the Genera Plantar um, species one and two of the Prodromus were duly 
reduced to the genera Epaltes Lessing, and Centipeda Loureiro, respectively, but 
8. 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. 8. Russeliana is apparently a species of Epaltes, and manifestly akin 
to E. australis, but distinct from that and probably endemic in the Western
