The species Lippia sidoides Cham. (Verbenaceae) is known in Brazil as "alecrim-pimenta", a typical shrub from the Northeastern Brazil vegetation. This work was carried out in the Agronomical Sciences Institute from Minas Gerais State University (UFMG), Montes Claros, Minas Gerais State, Brazil, in order to study the vegetative propagation of this species in rooting bed under controlled humidity. Herbaceous cuttings were treated with the following concentrations of indolebutyric acid (IBA): 0, 250, 500, 750, and 1000 mg L-1 for 24 hours. The experimental design was completely randomized (CRD) with five replicates of 10 cuttings each. After 45 days, root and sprout numbers, the highest root length, and rooting index and percentage were evaluated. Root length and number and rooting index had significant differences among IBA concentrations. However, rooting percentage was not significantly affected, probably due to the control of relative humidity and the maintenance of cuttings from leaves.
