Sclerocarpus, are referred by him to the first group, and 
Siegesbeckia, Jegeria, and Zaluzania, to the second group 
of his Siegesbeckiées. His Ogiera, which he has placed in 
this last, is identical with Podanthus of Lagasca, and 
Euxvenia of Chamisso, arranged in the preceding subfamily 
of Hélianthées- Rudbeckiées, but which I am rather dis- 
posed to refer to Spilanthee. All three genera have been 
founded on the same species, namely, Podanthus ovatifolius 
of Lagasca. 
* The Madia mellosa of Molina, and viscosa of Cava- 
nilles, are clearly the same with Madia sativa, and not even 
entitled to the rank of varieties. Molina has strangely 
attributed to M. sativa petiolate leaves, which being oc- 
casionally narrowed at the base may have originated that 
error, and also the confusion in which the species has 
been hitherto involved in Botanical works.” 
For the foregoing valuable account of the genus Madia 
we are indebted to Mr. Don, of whose extensive knowledge 
of the very difficult Natural order to which it belongs, we 
have been fortunate enough to be able to avail ourselves. 
The species is a hardy annual, recently discovered on 
the north-west coast of North America by Mr. Douglas, 
from whom it was received by the Horticultural Society 
last spring. In Mr. Douglas's despatch, it was spoken of 
as a very handsome plant in the way of Coreopsis tinctoria ; 
we do not, however, find it by any means equal in beauty 
to that favourite species. To be cultivated in perfection, 1t 
should be sown about June, so as to come into flower after 
the heat of summer is passed ; and even then a shady place 
should be chosen for it ; for its flowers are so impatient of 
exposure to light, that they are scarcely expanded, in 
bright sunshine, before they contract again, and the rays 
curl inwards, hiding the bright yellow and brown, on which 
its beauty entirely depends. The plant grows 2 feet high, 
flowers in about two months after being sown, and remains 
in beauty about six weeks or two months. It ripens seeds 
abundantly. 
We have only seen it cultivated in rich Garden soil ; 
probably it would be improved by being put into very 
poor earth. a
