— 
This species differs from the one already published in the 
present work in little except its smaller size, and differently 
formed flower heads, which are impressed at the base with 
a cavity for the peduncle, and like the peduncles themselves 
are slightly downy. 
It is an annual plant, flowering for about six weeks at 
different periods of the year, according to the season at which 
its seeds are sown. 
Professor De Candolle, in a manuscript list of the genera 
of Composite, which we have just received from him, 
includes it in his first series Tubuliflore, fourth tribe Senecio- 
nidee, fifth sub-tribe Helemee, first division Gaillardiee, 
second sub-division „Buhelemee, along with Cephalophora 
and Helenium, both of which are known in our gardens. 
We observe that Professor De Candolle attributes the genus 
to Cassini, but we have not succeeded in discovering it in any 
of the writings of that most unmethodical of Botanists.
