_Buchnera_ is a genus of plants established by LINNAEUS in honour of A.
E. BUCHNER, a German naturalist.

Of this genus, nine species are enumerated in the 14th edition of the
_Systema Vegetabilium_, by Professor MURRAY.

We learn from Mr. AITON, that the present species (a native of the Cape)
was introduced to the royal garden at Kew in 1774.

It cannot boast much beauty, yet as it occupies but little room, grows
readily from cuttings, and flowers during most of the summer: it obtains
a place in most greenhouses.

The foliage of this plant greatly resembles that of Ground Ivy, and its
branches trail on the ground somewhat in the same manner, extending to
the length of several feet; but it is not on the ground that it is best
seen, as its flowers are apt to be hid among the leaves: it appears most
advantageously when growing in a pot, placed on a pedestal, or in some
elevated situation, where its branches may hang carelessly down: thus
treated, when fully blown, it becomes a most pleasing object.

LINNAEUS, the son, in his _Suppl. Plant._ observes, that the _Disandra_
varies extremely in the number of its stamina, as it does also in the
divisions of its calyx, and corolla; in this respect;, indeed, we do not
know its equal: fortunately for those systems of Botany, which are
formed from the number of certain parts of the fructification, few such
inconstants exist.

Professor MURRAY observes, that seven is the most prevalent number of
its stamina, five the most natural.

LINNAEUS describes it as a native of the East; Mr. AITON informs us, that
it was introduced here about the year 1771, from Madeira.

It flowers during most of the s
