Revision of Lymania (Bromelioideae-Bromeliaceae) an endemic genus to Bahia, Brazil.

Bahia state is a major Brazilian center of diversity of Bromelioideae genera, but the identity and taxonomic status of several species were still uncertain in the absence of revisions. Generic-level systematics in Bromeliaceae, subfamilyBromelioideae, is poorly understood and problematic. Several generic-level taxonomic changes have been proposed in Bromelioideae since the last revision in Flora Neotropica, 1979. Read in 1984 described Lymania to accommodate furrowed or winged ovary species from the genera Aechmea, Araeococcus and Ronnbergia. Our revision is based on morphological variation in herbarium and living plants in order to improve species delimitation within the genus Lymania. One species, Aechmea brachycaulis, was transferred from the position as synonymy of Lymania corallina, resulting in one new combination: Lymania brachycaulis. In total, eight species are recognized in Lymania, and all are endemic to the eastern coast of Bahia (Atlantic Rain Forest) and known only from a few localities. The conservation status of these species is 'endangered' according to IUCN criteria. We provideA key, full descriptions, distribution maps, and a list of specimens examined.
