=Botanical Origin=—The Buchu leaves are afforded by three species of
_Barosma_.[427] The latter are erect shrubs some feet in height, with
glabrous rod-like branches, opposite leaves furnished with conspicuous
oil-cells on the toothed margin as well as generally on the under
surface. The younger twigs and several parts of the flower are also
provided with oil-cells. The white flowers with 5-partite calyx, and
the fruit formed of five erect carpels, are often found, together with
small leafy twigs, in the drug of commerce.
