though he admits that it performs the office of that part*. In 
some instances this filament terminates with the anthcra ; but in 
others is extended beyond it, either in a subulate, ovate, bilo- 
bate, or other peculiar form, which I have always found charac- 
teristic of the genus; and which, after the great distinction of a 
single or a double anthera, I consider as the chief generic distjosr, 
tion of these plants. 
"The first result of this system. will be found. to, be.the. ‘separa: 
tion of the. true. Scitaminean: plants. from those. which, although 
of the same order, possess neither their peculiar construction nor. 
their inherent qualities. The latter of these may perhaps be 
properly denominated Canne ; à name applied by Jussieu to the 
whole tribe ; whilst the appellation of. Scitaminee should. be re- 
served for the true aromatic. plants only.. Other. important 
changes will also be indispensably necessary. The. genus. Amo- 
mum appears to include two genera, as distinct. from. each other. 
in their growth, habits, and qualities, as in their generic charac- 
ters. To one of these, which | comprehends the plants of the 
Ginger tribe, - I given the name. of Zingiber,— res stricting

method, the Amomum zedoaria appears to be a Curcuma ; the

This is also the opinion of Mr. Dryander, which on this subject, as on all others con- 
necied with. natural history, is entitled to the highest respect; and Dr. Swartz proba- 
bly | learn it at Sir Joseph Banks's when i England. In fact, this organ, like many. 
others, both in the animal and vegetable economy, performs two offices, and is both 
the filament supporting the anthera, and the upper lip of the nectary; but I: have pre- 
ferred the denomination of filament for the sake of consistency with the other plants of 
this order, which have a proper filament, to which I have also been: indien €
