Abstract
Boerhavia species are widely used in African traditional medicine. Four species of the genus occurring in
Nigeria have been investigated morphologically and phytochemically. Epidermal cells are either
polygonal in shape with straight anticlinal walls or irregular with curved or undulate walls. The cells are
variable in size and thickness both within and among species. Anomocytic stomata are found in all
species except in B. drum where a mixture of both anomocytic and anisocytic types occur. Trichomes
are uniseriate and unbranched but are variable in size, distribution and abundance. These features are
discussed in relation to the practical identification of the taxa. Phytochemically, screening showed that
all species contain flavonoid or phenolic constituents while only traces of alkaloids and tannins are
present. Free or combined anthraquinones and saponins were not detectable in any of the four taxa
screened.
