Clonal propagation was attempted in Thespesia populnea. Among the four rooting media used, namely pallam sand, potting mixture, vermiculite, and composted coir pith, pallam sand was the most effective one. Among the four different hormone treatment combinations (1000, 2000,3000, and 4000 mg l-1 of IBA), IBA at 3000 mg l-1 was promising for this species. Composted coir pith failed to produce any response. Under in vitro conditions, direct shoot and root formation were noticed in MS medium or Woody Plant Medium containing BAP (1.0 mg l-1) and IAA (0.1 mg l-1).
