CosMEUA, R. Bromn. From kosmeo, to adorn ; in 
reference to the beauty of the flowers. Linn. 5, 
Or. 1, Nat. Or. Epacridaceee. This is a pretty

CosMus, CavaniUes. From Aroimoa, beautiful ; in allu- 
sion to the appearance of the species. Linn. 19, Or. 
2, Nat. Or. Composita. This is a genus of very 
beautiful plants, well deserving of extensive cul- 
tivation. The flowers are not very much unlike 
those of a single dahlia, to which the genus bears a 
close resembl2ince ; and the perennial species re- 
quires exactly the same treatment C. tenuifolius 
being an annual, the seeds must therefore be sown 
on a hotbed early in spring, and planted out in the 
flower-garden about the end of May ; but a few 
plants should be kept in the greenhouse, from 
which the seeds should be gathered-
