It is a hardy annual, usually flowering in the autumn. 

 The flower reminds one of that of some of the small Rud- 

 BECKi^ ; the foliage has been likened to that of a Verbesina 

 or a BiDENs. 



The species do^ not seem to have fallen in the way of 

 Messrs. Humboldt and Bonpland during their botanical re- 

 searches in Mexico, no mention being made of it in the 

 " Nova Genera et Species " of M. Kunth. 



The seed of the disk i& described as cuneately compress- 

 ed with a naked top ; of the rcn/ as turbinate and crowned 

 with three subulate teeth. We have not ventured to place 

 it in any of the five sections under which M. Cassini has 

 attributed his tribe of Heliantheae, not having had an oj>* 

 portunity of inspecting any part of the plant oui-selves. 

 The names of these sections are, J, ffelianthecB-heleniece : 

 2. Helianthece-coreopsidece : 3. Helianikece-prototi/pecB : 4. 

 Helianthece-rudbechiece : 5. Helianthece-milleriece, Kach 

 of which is distinctly characterized in vol. 20. p. 347. of 

 Dictionnaire des Sciences naturelles. 



By the later Volumes of the ** Dictionnaire des Sciences 

 naturelles " we find that Heuanthus has been distributed 

 by M. Cassini under three subgenera (definite sections of a 

 genus with a title not necessarily independent of the principal 

 one) ; and that genus happening to have been exemplified 

 in the present work by three species^ each of which fells 

 under a distinct section of this new arrangement, we shall 

 take the opportunity of a vacant leaf to add some account 

 of them, with versions of their characters from the French 

 text, keeping as clear as we can of the inexpedient neology 

 of the original.
