Pollination Biology López-Colón, Jonathan A. [1], Davila, Eva [2], Marrero-Solís, Solimar [3]. Sexual Reproduction and Pollination Agents of Chamaecrista glandulosa var. mirabilis (Leguminoseae: Cesalpinoidea). The pollen transference, known as pollination, is a process on plants that involves the relationship of a physical agent. In this case, this relationship is between hymenopterans and Chamaecrista glandulosa var. mirabilis, an endemic and endangered plant of Puerto Rico. Its populations are found on the Laguna Tortuguero Natural Reserve. Its habitat is open areas of silica sands with high temperatures. Individuals of C. glandulosa were treated to measure the pollination capability of the population. To study the autogamy possibility or buds were placed in small wire mesh bags which prevented the interaction of pollinators or visitors. Other buds were used as experimental controls. Flowers with mature anthers were collected and its pollen was analyzed and characterized. Usually the flowers individuals were visited during early hours in the morning by hymenopterans. Some last ones of these visitors observed and analyzed in the laboratory to study the presence of the pollen on theirs bodies and determine if they were pollination agents. The pollinators were identified Xilocopa virginica (Apidae) and bees of the family Andrenidae, which apparently also visit and might pollinate other plant species. The plants with bagged buds did not produce fruits of so autogamy was discarded or reproduction in this species. The buds used as controls produced fruits, suggesting that its sexual is based on the interaction with pollinators.
