round knobs: seed vessels we have not seen.
[Footnote 2: What the use of this very extraordinary apparatus may be we
can at present scarcely conjecture, future observation may perhaps
enable us to speak more decisively; when we figure the _Diosma
ericoides_ we shall probably have more to say of this species.]

_Borbonia_ is a genus of plants established by LINNAEUS in the 6th
edition of his _Genera Plantarum_; of this genus there are six species
enumerated in the 3d edition of the _Species Plant_. and two in the
_Hort. Kew._ the latter of which, the _crenata_, introduced from the
Cape by Mr. MASSON, in 1774, is here figured.
It is a small shrubby plant, rarely exceeding the height of three feet,
producing its flowers in a small cluster on the summits of the branches;
these are of a yellow colour, and have nothing about them peculiarly
singular, or beautiful; it is the foliage alone which renders this plant
desirable in a collection.
It flowers from June to August, and in favourable seasons ripens its
seeds, by which the plant is usually propagated.
