The paper discusses the growth of cell suspension cultures of <em>Amsonia tabernaemontana</em> Walter established from callus of hypocotyl origin. The cell number and growth increment were determined. Cellular aggregates developed well in the Wood and Braun (WB) medium with 1 mg/l NAA and 0.5 mg/l kinetin (growth increment 712.4). When the aggregates were cultured on WB media without NAA and kinetin or with 0.02 mg/l kinetin and 3 mg/l IAA, Toots developed an the aggregates. Examiination of the roots and cell suspensions indicates that the Toots are richer in alkaloids than the callus and cell suspensions.
