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 abundanee. 
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 the 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.
