It is a hardy annual, usually flowering in the autumn. 
The flower reminds one of that of some of the small Rup- 
BECKI; the foliage has been likened to that of a VERBESINA 
or a BIpENs. 2 
The species does 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 is described as cuneately compress- 
ed with a naked top; of the ray 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 Helianthee, not having had an op- 
portunity of inspecting any part of the plant ourselves. 
The names of these sections are, 1. Heliantheaw-heleniew : 
2. Helianthee-coreopsidee: 3. Helianthew-prototypee: 4. 
Helianthew-rudbeckiee : 5. Helianthea-milleriee. Each 
of which is distinctly characterized in yol. 20. p. 347. of 
Dictionnaire des Sciences naturelles.

___ By the later Volumes of the “ Dictionnaire des Sciences 
naturelles” we find that Hetianruus 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 falls 
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.
