One hundred and ten species of the Nigerian Asteraceae were examined for protein, starch, fats and oils using standard detection procedures. Out of these number of species, 96 were being studied for the first time. Fats and oils were found in all the species investigated comprising herbs and shrubs, (100% detection rate). Starch was not detected in any species, showing a zero persent detection rate. No correlation could be establisnhed between life form and the nature of ergastic substance in the Asteraceae.

Seed morphology of 136 species distributed in 68 genera have been described. Of these , seed morphology of 51  genera are described for the first time. Systematic keys based on seed morphology for  the identification of genera have been provided.
