This plant recommends itself by its fragrance rather than its beauty, so
delicious indeed is the odour it diffuses, that it is considered as
essential to every green-house and stove.

"It grows naturally in Peru, from whence the seeds were sent by the
younger Jussieu to the royal garden at Paris, where the plants produced
flowers and seeds; and from the curious garden of the Duke d'Ayen, at
St. Germain's, I was supplied with some of the seeds, which have
succeeded, in the Chelsea garden, where the plants have flowered and
perfected their seeds for some years." _Miller's Gard. Dict._

You may consider it either as a stove or a green-house plant, the former
is more congenial to it in the winter season.

A pure atmosphere is essential to its existence, as I experienced at
Lambeth-Marsh, where I in vain endeavoured to cultivate it.

It is propagated by cuttings as easily as any Geranium, and requires a
similar treatment; in hot weather it must be well supplied with water,
and in winter carefully guarded against frost, so fatal to most of the
natives of Peru.

I am indebted for seeds of this plant to my very worthy and liberal
friend NICH. GWYN, M. D. of Ipswich, to whose penetrating
genius, and learned researches, Botany owes much.

As its name implies, it is a native of the province of Tangier, on the
Barbary coast; appears to have been cultivated here, according to the
_Hort. Kew._ in 1713, but is not mentioned in the 6th 4to. edit. of
MILLER's Dictionary.

It may be considered as forming a valuable addition to our stock of
annuals, being a beautiful plant, and easily cultivated:
