Sclcrocarpus, are referred by him to the first p:roiip, and 

 Siegcsbeclda, Jci'geria, and Zaluzama, to the second group 

 of his Sicgc.s/jccliiccs. His 0<iicni, which he has phiced in 

 this last," is identical with PoduHthiis of I.ai^asca, and 

 Eiuru'ui of Chamisso, arranged in the |)receding- sublaniily 

 of IlcHaiithccs-liudbccliiku, but wliich I am rather dis- 

 jiosed to refer to Spilauthac. All three genera have been 

 founded on the same species, namely, PudanlliiLs uvatifoliua 

 of Lagasca. 



" The Madia mdlosa 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. mtiva 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 desi)atch, it was spoken of 

 as a very handsome plant in the way of Coreopsis tinctoria ; 

 we do not, iiowever, find it by any means equal in beauty 

 to that favourite species. To be cultivated in perfection, it 

 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 

 l)oor earth.
