small, and itis by no means with confidence that I now refer 
this dubious plant to the genus Petroselinum, where it will 
stand next to the P. trifoliatum (Wats.) According to present 
unnatural arrangements of the Umbellifere into generic 
groups, I have felt obliged to separate the Ammi Huntii from 
these two; although the three species, united with a fourth 
from the Island of Flores (of which I possess only a single 
very immature specimen), might form together a natural- 
looking genus by their similarity of foliage and general habit. 
They combine badly with the other species of Petroselinum ; 
and the Ammi Huntii is referred to its genus more on 
account of the pinnatifid involucrum. than aught else, 
though, on the whole, associating with .4. majus better 
than the others do with any species of Petroselinum. In 
the annexed character I compare the new species with P.
