Abstract: Single nodes from young top shoots of <i style="">Decalepis</i> <i style="">arayalpathra</i> were cultured on Murashige and Skoog’s (MS) agar medium supplemented with 0.1 to 5.0 mg l<sup>-1</sup> BAP. All the concentrations of BAP induced single axillary shoot of varying length. However, MS medium supplemented with 1.0 mg l<sup>-1</sup> BAP supported rapid growth and produced the longest shoots (6.8 cm) in 60 days. For further multiplication, the nodes and shoot tips from <i style="">in vitro</i> derived shoots were recultured on MS medium fortified with 0.5 mg l<sup>-1</sup> BAP, which produced the 8 cm long shoots having 5-7 nodes in 30 days period. Further, the top microshoot cuttings (3-5 cm long) with 2-3 nodes, subcultured onto MS medium supplemented with 1.5 mg l<sup>-1</sup> IAA, produced an average of 6.3 roots in 30 days period. The rooted plants after hardening were reintroduced into their natural habitat at Kallar reserve forest, Thiruvananthapuram. After two years, 84% survival of reintroduced plants was recorded.
