H. tubceformis ; foliis longe petiolatis ovatis acuminatis basi cuneatis subser-

villosissimis, anthodio foliaceo patulo elongate Spreng. syst. 3. 616.

The accompanying figure was taken from a potted plant 

 that had been raised in the Garden of the Horticultural 

 Society, from Mexican seeds presented by John Bid- 

 dulph, Esq. It flowered in the Greenhouse in August 

 last ; and in that situation did not acquire a stature ex- 

 ceeding 2 feet : but if grown in the open ground, as a hardy 

 annual, it is said to arrive at the height of 8 or 9 feet. 



It is chiefly remarkable for the very much thickened 

 peduncle, which becomes quite hollow, although the stem 

 itself, from which it proceeds, is perfectly solid. 



The involucrum, or anthodium, as some prefer to call it, 

 is very leafy, and covered with a silky hairiness. The 



leaves of the involucrum are very unequal in size ; some of 

 them being nearly as long as the florets of the ray.
