Seeds of this plant were received by Mr. Thompson, of Ips- 
wich, from Mexico. It is doubtless a handsome species of Cos- 
mos. ‘The question is if it can be safely referred to any described 
species. The genus is described as having bipinnate leaves (or 
“folia bipmunatisecta”). Our plant has its leaves simply pin- 
nate. ‘Two species are described and figured with foliage of this 
character, one the C. scabiosoides of H. B. K., and Lindley, in 
Bot. Reg. 24. t. 15, but that has. much smaller flowers, 
though nearly of the same colour as ours, and entire ligulate 
florets ; the other is the C. diversifolius of Otto in Knowles and 
Westcott, 7. c., whose flowers sufficiently correspond with ours 
except in colour. Unfortunately, in both cases, only upper por- 
tions of the plant (without root-leaves) are given, and the foliage —
