The flame vine (Pyrostegia venusta (Ker-Gawl.) Miers) is a semihardwood vine, vigorous, native, native, occurring in all Brazilian biomes and ornamental potential. Technical information about the propagation of this species will contribute to the production of seedlings and with that, their greatest use in landscaping. This study aimed to evaluate the influence of the number of leaves and nodes in rooting intermediate flame vine. The experiment was conducted under conditions of intermittent mist. The experimental design was a randomized block in factorial 2 x 3, being respectively cuttings with one or two nodes, and zero, one or two leaflets. We used four replicates with plots consisting of 12 cuttings placed in substrate of rice hulls in polystyrene trays with 72 cells. We evaluated at 84 days the porcentage of rooted cuttings, length of shoots, dry weight of shoots and, per cutting, average: number of roots - first order; maximum length of each root of the first order, volume and dry weight of roots. It was observed that cuttings with two leaflets enabled 66% of rooting, greater length and dry mass of shoots. The higher quality of the root system occurs with stakes with two leaflets and two nodes. The spread of flame vine is efficient with semi-hardwood cuttings with two nodes and two leaflets, kept in a greenhouse under intermittent mist.
