Introduction and objectives: The species of Papilionoideae have floral traits or strategies related to the pollination mechanisms and promote cross pollination such as mechanic barriers, spatial or temporal separation of the maturation of the sexual organs, among others. The aim of this study was to provide a detailed morphological description of the androecium and gynoecium of 17 Papilionoideae species native to Lerma Valley (Salta-Argentina).
M&M: We studied on field and laboratory quantitative and qualitative traits of the androecium and gynoecium of 17 Papilionoideae species belonging to nine genera and five tribes, and analized from a functional point of view those traits that could be related to the reproductive system and to the pollination mechanisms.
Results: Our results show that most of the species are homogamous and have monadelphous or pseudomonadelphous with basal fenestration androecium, monomorphic anthers, variable forms of the style and stigma, stylar trichomes, peristigmatic trichomes and stigmatic membrane. We registered for the first time some traits in some of the species, such as the spontaneous rupture of the stigmatic membrane during the anthesis and the reduction of anthers-stigma distance after the maturation of both sexual organs.
Conclusions: All the studied species have floral traits associated with a reduction in self-pollination. Detailed information on morphology and other traits of the androecium and gynoecium has been obtained, and could be used to describe better their pollination mechanisms and to understand some aspects of their reproductive biology. |

Introducción y objetivos: Las especies de Papilionoideae presentan características florales o estrategias relacionadas con los mecanismos de polinización y que favorecen la polinización cruzada como la presencia de barreras físicas, la separación espacial o temporal en la maduración de los ciclos fértiles, entre otras. El objetivo de este trabajo fue brindar una descripción detallada de la morfología del androceo y gineceo de 17 especies de Papilionoideae nativas del Valle de Lerma (Salta-Argentina). M&M: Se estudiaron a campo y en laboratorio características cuantitativas y cualitativas del androceo y el gineceo en flores de 17 especies de Papilionoideae, pertenecientes a nueve géneros y cinco tribus y se analizaron desde un punto de vista funcional aquellas características que estarían relacionadas con el sistema reproductivo y los mecanismos de polinización. Resultados: Los resultados indican que la mayoría de las especies son homógamas, presentan androceo monadelfo o pseudomonadelfo con fenestras basales, anteras monomórficas, formas variables del estilo y del estigma, tricomas estilares y periestigmáticos y membrana estigmática. Se registraron características descritas por primera vez para algunas de estas especies tales como la ruptura espontánea de la membrana estigmática durante la antesis y la reducción de la distancia anteras-estigma luego de la maduración de los ciclos sexuales. Conclusiones: Todas las especies estudiadas presentan características florales asociadas a la reducción de la autopolinización. Se obtuvo información detallada sobre la morfología y otras características del androceo y gineceo que podría ser utilizada para describir mejor sus mecanismos de polinización y para comprender aspectos de su biología reproductiva.
