|Abstract: ||Foliar epidermal studies were carried out on Digitaria iburua Stapf, Digitaria exilis Stapf and
Digitaria barbinodis Henr. with the aim of determining the patterns of variation in their epidermal
characteristics and assessing the value of leaf epidermal characters in the identification of these
culturally important species. Micro hairs, silica bodies, short cells, anticlinal wall pattern, epidermal
cell shape and stomata index were diagonistic characters. While micro hairs were distributed on
the surfaces of Digitaria exilis and Digitaria barbinodi, they were absent in Digitaria iburua. Short
cells were present on the surfaces of Digitaria iburua and Digitaria barbinodis but absent on
Digitaria exilis. Stomata index was smallest in Digitaria barbinodis distinguishing it from the other
two species. The epidermal cell shape varied from rectangular to polygonal while the anticlinal wall
pattern varied from straight to wavy in the three species. Other useful characters for distinguishing
the species are epidermal cell size, stomata size and stomata number.|
