mannia aromatica, whose sepals are three, and very concave, 
and the petals six in two rings, or occasionally eight, in 
consequence of the addition of one petal to each ring. 
Endlicher’s character cannot then have been taken from 
T. aromatica, but possibly belongs to T. dipetala, which 
perhaps does not belong to the genus. 
The species is a handsome evergreen bush, with dull 
purple branches, and light green leaves, distinctly marked 
with transparent dots; they are of a dead green and veinless 
on the underside. Mr. Gunn informs us that it is very 
abundant in Van Diemen’s Land. “Between Burghley (at 
the Surrey Hills) and May Day Plain, the Van Diemen's 
Land Company's track, commonly called road, to Launceston, 
is cut through a thicket of it for upwards of a mile; at that 
place its usual height is from nine to twelve feet. It always 
grows in the richest humid soil; in the neighbourhood of 
Launceston, usually on the margins of rivers or small streams 
in umbrageous ravines. Every part of the plant is highly 
aromatic and pungent to the taste. The fruit is occasionally 
used as pepper." a 
In fact it is nearly related to the aromatic Winters bark, 
Drimys Winteri; from which its unisexual flowers and soli- 
tary carpels chiefly distinguish it; and it must follow the 
affinity of that plant. For this reason it seems necessary to 
associate it with the order of Magnoliads rather than with 
that of *Kadsurads (Schizandraceæ) or Anonads. 
These three orders are generally distinguished by the fol- 
lowing characters. Magnoliads are bisexual, have stipules 
of large size, and their flowers have an imbricated æstivation. 
Kadsurads resemble them in all things, except the want 
of stipules, and their flowers being absolutely unisexual. 
Anonads are bisexual like Magnoliads, but they have no 
stipules, -their corolla is valvate, and their albumen ruminate. 
Moreover Magnoliads are astringent subaromatic trees or 
bushes; Anonads are similar in quality, but they are 
more aromatic; Kadsurads are scrambling plants with no 
aroma. Ît is a question of some interest to determine to
