Adoption of a name
That M. pigra was found to share the same Kinyarwanda name with A. brevispica Harms and C. decapetala (Roth) Alston [Leguminosae] which is understandable. They belong to the same family of Leguminosae, and highly resemble each other. For instance, they all have pinnate leaves, prickly stems and fruits in the form of pods. Instead, intriguing was to realize that Rosa sp., a species that belongs to such a distant family as that of Rosaceae, shares the same name.
