n this study, the achene mucilage content of six Turkish endemic Tripleurospermum taxa, namely T.
baytopianum E. Hossain, T. conoclinium (Boiss. & Bal.) Hayek, T. fissurale (Sosn.) E. Hossain, T.
hygrophilum (Bornm.) Bornm., T. rosellum (Boiss. & Orph.) Hayek var. album E. Hossain and T.
ziganaense Inceer & Hayirlioglu-Ayaz was determined by micro-staining reactions. Within the examined
taxa, the mucilage cells on the achene surface are capable of forming a musilage envelope resembling
a gel during hydration. The mucilage is heterogeneous and chemically contains pectin and cellulose.
There are differences in the capacities of mucilage forming as well as adhesive to soil of the achenes in
the studied taxa. The mucilage could have great importance in distribution and adaptation of
Tripleurospermum taxa to diverse environments.
