The seeds were sown by Mr. Fairbairn, in March, and the plants kept in the green-house till very late in the summer, when to accelerate their blowing, they were removed into the dry stove: it is worthy of remark, that these plants, even late in the autumn, shew no signs of blossoming, but the flowers at length come forth with almost unexampled rapidity, and the seed-vessels are formed as quickly, so that if the flowers were not very numerous, their blossoming period would be of very short duration; future experience may perhaps point out the means of making the plant blow earlier: in Spain, the blossoms appeared later than here, Mons. Cavanille observed them in the Royal Garden, in November and December, most probably in the open ground, as no mention is made of the plants having been preserved from the weather.
It was not till long after our description was taken, that we had an opportunity of seeing Mons. Cavanille's most accurate and elegant work, above quoted, in which this plant is first figured and described; we have selected the most essential parts of his generic character, and adopted his specific description: there is one point, however, in which we differ from him; the part which he regards as the fifth Petal, we are inclined to consider rather as that indescribable something, called by Linnæus the Nectary, it is indeed of little moment whether we call it a Petal or a Nectary, but there are several reasons why, strictly speaking, we cannot regard it as a Petal: in general the number of Petals correspond with the number of the leaves of the Calyx, those of the latter are four; the base of this Nectary originates deeper than the claws of the Petals, springing in fact from the same part as the Filament, its structure, especially the 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 alæ 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 Circæa.
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.
