AB  - Anatomical studies on the petiole of eight <I>indigofera </I>species of the tribe galegeae common in eastern
Nigeria were carried out with the aid of a light microscope. An analysis of the features of the internal
arrangement of the petiole shows that these taxa possess vital characters that could be used in their description
with a view of establishing taxonomic relationship among the species. The epidermal layer and collenchyma
cells as well as crystal types are some of the characters assessed and discussed among the <I>indigofera </I>species
investigated. The presence of uniseriate, tubular and closely parked epidermal cells in <I>I. paniculat</I>a,
<I>I. stenophylla </I>and <I>I. terminalis </I>is of taxonomic. The well-developed large distinct angular and lacuna
collenchyma cells in <I>I. prieurean</I>a, <I>I. senegalensis </I>and <I>I. tinctoria </I>are significant. Furthermore, the presences
of variously shaped crystals and tannins in most of the species studied conforms the highly tanninferous
nature of these taxa and hence the mechanical and storage roles of these crystal and tannins in plants.
