With very much the aspect of Chrysanthemum corona- 

 rium, except that it is not half so tall, it agrees very nearly 

 in structure with the widely different genus Madia, especially 

 in having the ovaries of the florets of the ray enwrapped in 

 the bases of the leaflets of the involucre. 



This species is a hardy annual, introduced by the Horti- 

 cultural Society from California, where it was found by Mr. 

 Douglas. It flowers in the months of August and September, 

 ripening seeds in abundance. 



Of the dissections in the accompanying plate, fig. 4 repre- 

 sents an anther; fig. 2 a floret of the ray with its base 

 enwrapped in the scale of the involucre ; and fig. 3 the top 

 of tJie style with the two subulate hairy branches of the 

 stigma ; but fig. 1 does not belong to the plant ; it has been 

 introduced by some negligence on the part of the artist.
