The thyme-leaved buchu belongs to Rutaceae family, a group of aromatic trees and shrubs, sometimes known as the citrus family (1). The thyme-leaved buchu is a single-stemmed shrub that branches near ground level, and grows to form a rounded bush. The leaves are narrow ovals (2), and when crushed, produce a mild aroma from the oil glands that can be seen as small, translucent, black dots on the leaves (1). The small pink or mauve flowers (eight millimetres wide), grow in loose clusters at the tips of the branches (4), and the fruits are small berries (2).
