South-western Australia, Drummond.—From the style, this little — 
plant should perhaps be referred to the Asteroideæ ; but none of the : 
Tarchonanthee are homogamous, and the Buphthalmeæ have a palea- 
ceous receptacle. Tt is evidently related to the following, viz., Antho- — 
cerastes, which has a nearly similar style, and the aspect of some small 
Gnaphaliee or Tarchonanthee.
