Empleurum unicapsulare commonly known as False Buchu or River Buchu in English and Bergboegoe or Wildeboegoe in Afrikaans is a single-stemmed, evergreen shrub, which has a similar growth habit to a willow tree. It slender and upright growth form with its hanging, spreading branches and interesting flowers, makes it an ideal accent plant in any garden. It belongs to the citrus family and its diagnostic characters are the undivided gland-dotted leaves, dehiscent fruit and flower structure. The false buchu is a shrub or small tree of about 4 m and is completely glabrous (hairless). The undivided, linear, dark green leaves, 20-60 x 3 mm, have finely serrated edges and are alternately arranged on the branches. They are richly endowed with oil glands which are visible on the underside of the leaves and when crushed have a resin-like scent. The branches are erect, rod-like and brownish red. Branchlets are numerous, straight, slender and pale greenish yellow. A closer look shows that the branches are completely gland-dotted. Empleurum unicapsulare is monoecious (bearing unisexual flowers on the same plant) or polygamous meaning having male, female and bisexual flowers on the same plant. The calyx of the flower is 4-lobed and petals are absent. It has four fertile stamens with the staminodes and disc absent. The ovary is superior with 2 ovules. During the peak flowering season from April to September, small greenish flowers appear, either solitary or are borne in pairs in the leaf axils.
