s to be thrust down in the centre betwixt the
three plants, for them to twine around: the warmer and more sheltered
the situation, and the richer the soil in which they are placed, the
taller the plants will grow; by raising them on a hot bed, you may
anticipate their natural time of flowering, and be more certain of
obtaining good seed.

PASSERINA. _Burm. Afric. t. 47. f. 1._

The plant here represented appears to have been first described and
figured by BURMAN, in his _Pl. Afric._ under the name of _Passerina_:
LINNAEUS introduced it in the 3d edition of his _Sp. Pl._ by the title of
_Passerina dodecandra_; discovering afterwards that it had in reality
only four stamina, and that the other eight substances, mistaken for
such, were so many glandular nectaria, he made in his _Mantiss. Plant._
a new genus of it, by the name of _Struthiola_, and assigned it the
trivial name of _erecta_; in the abbreviated generic description given
of it by Prof. MURRAY, an alteration is made in this generic character,
and what before was considered as Corolla, is here regarded as Calyx; no
reason is assigned for this alteration, and we are at a loss to account
for the propriety of it.

Mr. MILLER, who cultivated this plant in 1758, describes it in his
dictionary, and observes very justly, that though its branches when
young are erect, when loaded with blossoms they incline to a horizontal
position; hence the term _erecta_ becomes an improper one, and should be
changed for one more expressive.

This species of Struthiola is a very common shrub in our greenhouses,
will grow to the height of five or six feet, and, though not so
ornamental as some other plants, has the merit of flowering during most
of the year, and often in the depth of winter.

Is readily increased by cuttings.
