The genus Campomanesia (Myrtaceae) in atlantic rainforest fragments in sergipe, Northeast region Brazil

摘要

The Atlantic forest is one of the ecosystems of Brazil that has suffered the greatest destruction and it is still imperiled, especially in the Northeast. Sergipe is one of the states where the Atlantic forest has been most greatly reduced, but it still has some fragments varying in size and degree of conservation. Despite their importance, botanical studies within these fragments are still greatly needed. In this paper we report for the first time the occurrence of four species of Campomanesia in Sergipe: C. aromatica, C. dichotoma, C. guaviroba, and C. viatoris. The last, formally thought to be known from only two collections from Alagoas, has a relatively wide distribution in Sergipe, and is found in forest and restinga areas of different districts. Campomanesia guaviroba is reported for the first time from the Northeast of Brazil. We hope that studies on the composition of these remnants may contribute to the local preservation of this ecosystem and help future programs of forest restoration.We emphasize the need for a greater collecting effort, more studies on plant taxonomy, and the training of new specialists.
