944 Mr. Roscoz's New Arrangement of the Plants of the 
charácteristic is its simple uncrowned filament, terminating 
with the anthera which it supports; a distinction which sepa- 
rates it from all the rest of the tribe, except Philydrum and 
Hedychium ; from the first of which it is distinguished by the 
absence of the woolly. appendage at the base of the tube ; 
from the latter, by the anthera not being placed. marginall yon 
the filament ; and from both by its corolla, which (independent 
of the large-lobed. lip of the nectarium) consists of only. three 
segments, without any interior limb. - | 
I have no hesitation in referring to this ; pénus the Hellenia of 
Willdenow *, ( Heretiera Retzii ) and the plants given as Reneal- 
mias in Andrea Botanists Repository (fig. 360 and 421). 
These plants all agree with Alpinia both in habit and fructifica- 
tion. The growth is caulescent, the inflorescence terminal, the 
anthera flat and naked, the corolla has no interior limb (except 
the large petal-like nectarium may be so called)—circumstances 
of coincidence which surely forbid their being considered as dif- 
ferent genera. 
But although the genus pea of ' Willdenow, a and the Re- 
nealmias of Andrews's: Bot. Re } sorbed i 
genus Alpinia, this may not be th the F 
tata, the plant on which the genus Renealmia v was founded by the 
younger. Linneus 5 the racemus of which is described as not. 
* The name of Hellenia was em dee by E in honour of professor Hel- 
lenius of Abo, and applied to designate the plant now called Costus speciosus, which 
had before.been named by Kænig Banksia speciosa, and which Retzius had before in- 
tended to name Swartzia, but found that two genera | bad already been named by different 
persons after the eminent botanist to whom that appellation alludes. : Willdenow being 
aware that this plant was the Costus speciosus, abolished the name of Hellenia as ap- 
plied to it, but gave the same name to another tribe of- Monandrian plants, the Lan- 
guis of Koenig ; whic h Retzius had before, in a dinh Meran named Heritiera ; i 
that — having also been ERPE. ads
