A genus instituted by M. Labillarditre, but promulgated 
with a definition so vague and general, that the name is 
almost the only accession to science. Nor has our author 
been more successful in the description of his only species 
or in the figure he has given us from the dried plant; for, 
with all the attention we could use to ascertain whether 
his plant is specifically the same with the present or not, 
the point still remains so great a puzzle with us, that we 
have thought it safest to give no opinion on the subject. 
The generic character, now offered, is from the pen of 
Mr. Brown, and has been framed with the accustomed skill 
and foresight of that learned naturalist with a view to the 
cluster of confining genera from the same regions, which 
will be found near it in the concluding volume of his Pro- 
_ dromus of the Flora of New Holland. 
Achenium implying an indehiscent originally one-seeded 
seedvessel, while that of the present genus though eventu- 
ally one-seeded, having been found by Mr. Brown to ori- 
ginate in a germen with two ovula, one of which proves 
constantly abortive, he has thought it advisable to suggest 
Achenopsis as a more precise denomination for this sort of 
seedvessel,
