he lower part of it, is evidently
different from that of the Petals, corresponding indeed as nearly as
possible with that of the base of the filament.--_Vid._ DESCER.

Mons. CAVANILLE was induced to call this plant _Lopezia_, in compliment
to TH. LOPEZ, a Spaniard[1].

DESCRIPTION OF THE LOPEZIA.

ROOT annual.

STALK five or six feet high, branched almost to the bottom, square,
of a deep red colour, smooth towards the bottom, slightly hairy
above: _Branches_ like the stalk.

LEAVES alternate, ovate, pointed, toothed on the edges, more so on
the larger leaves, slightly beset with soft hairs, veins prominent
on the under side, usually running parallel to each other and
unbranched: _Leafstalks_ hairy.

FLOWERS numerous, from the alae of the leaves, growing irregularly
on hairy leafy racemi, standing on long slender peduncles, which
hang down as the seed-vessels are produced: in this and some others
of its characters, the plant shews some affinity to the _Circaea_.

CALYX: a _Perianthium_ of four leaves, sitting on the Germen,
leaves narrow, concave, reddish, with green tips, the lowermost one
widely separated from the others, and placed immediately under the
Nectary, _fig._ 1.

COROLLA four _Petals_ of a pale red colour, forming in their mode
of growth the upper half of a circle, the two uppermost linear, of
a deeper colour near the apex, jointed below the middle, with a
small green gland on each joint, standing on short round
footstalks, which are hairy when magnified, the two side Petals
nearly orbicular with long narrow claws, the part between the base
of the Petal and the claw of a deeper red or crimson, _fig._ 2.

NECTARY situated below the Petals, perfectly white, somewhat ovate,
the sides folding together, before the flower fully expands, nearly
upright, embracing and containing within it the Pistillum and
Stamen, on touching it ever so slightly with the point of a pin,
while in this state, it suddenly springs back and quits the
Pistillum, the lower elastic part of it is the
