Adventitious roots on branches of Tamarix aphylla (L.) Karst. develop in hyperhydric outgrowths of the lenticels. The following stages could be distinguished in the formation of the apices of these roots: (1) initiation, (2) a stage of random divisions, (3) a stage of transverse divisions, with respect to the longitudinal axis of the primordium, (4) formation of the procolumella, (5) differentiation of the procambium, the cortical meristem and the protoderm, (6) enlargement of the promeristem, and (7) emergence.
