| Because of the increasing and diversified demand for potted plants, there is interest in Argentina in commercial iris production (Iris x hollandica Tub.). Two experiments were performed at the Instituto Nacional de Tecnología Agropecuaria (INTA), San Pedro Agricultural Experimental Station (33º41 S, 59º41 W), Buenos Aires Province. The effects of increasing concentrations of paclobutrazol (PBZ) and combinations of PBZ and 6-benzylaminopurine (BA) were compared. Height, length of the cycle and rate of flowering were registered. Experiment 1: the bulbs were subjected to immersion in nine concentrations of PBZ: 0, 10, 20, 30, 40, 50, 60, 70 or 80 mg L-1 for 24 h. Experiment 2: the bulbs were immersed in three concentrations of PBZ: 0, 10 or 20 mg L-1 for 24... |

| Three new species of Cypella section Nais from South America are described and illustrated: C. charruana, C. gloriana, and C. uliginosa. Cypella charruana occurs in Santana do Livramento (southern Brazil) and in Rivera and Artigas (northern Uruguay). It is related to C. suffusa; however, it can be easily separated by its one-flowered spathes, outer tepals with narrowed claws, longer antheral filaments, and bigger anthers. Cypella gloriana is only found in São Vicente do Sul (central-western Rio Grande do Sul State, Brazil); this species is closely related to C. pusilla from which it can be separated by its larger perigone with shallower and broader concavity, outer tepals with narrowed claws, inner tepals with blades markedly narrowed and longer towards... |
