          Abstract

          Esta investigación crítica basada en el análisis de muestras colectadas y de material preservado en los herbarios más importantes del país representa la primera revisión del gé­nero Melochia L. para Venezuela. Se reconocieron diecisiete especies de este género locali­zadas generalmente en bosques deciduos, de las cuales Melochia lanceolata se reporta por primera vez para Venezuela. Melochiacaracasana, M.nodiflora, M.parvifolia, M.pyramidata y M.tomentosa son las especies con mayor distribución, ubicándose desde los estados centro-occidentales hasta el oriente del país. Se indican las secciones acompañadas de cla­ves, descripciones e ilustraciones con detalles de flores, frutos y semillas, e información del uso, hábitat y fenología de las especies. La forma del fruto, tipo de inflorescencia, senos que separan los lóbulos del cáliz, forma y pubescencia del pétalo, presencia de estaminodios y hábitat, son caracteres determinantes para identificar las especies.

          Translated abstract

          This critical research based on the analysis of collected samples and of preserved ma­terial in the most important herbaria of Venezuela represents the first revision of the genus Melochia for the country. Seventeen species of this genus, generally located in deciduous forests, were clearly recognized. Melochia lanceolata is reported for the first time to Venezuela. Melochia caracasana, M. nodiflora, M. parvifolia, M. pyramidata and M. to­mentosa are the species with widest distribution, being located from the center-western to the eastern states of Venezuela. The sections accompanied by keys, descriptions and illustra­tions are indicated with details of flowers, fruits, seeds and information of use, habit and phenology of the species. The form of the fruit, type of inflorescence, calyx lobe sinuses type, form and pubescence of the petal, presence of staminodia, and floral morphology are characters used to distinguish species.
