Abstract

ABSTRACT As part of a floristic survey of the vascular flora of Pedra do Elefante, Espírito Santo State, Brazil, a taxonomic treatment of the Anemiaceae is here presented. Fieldwork was conducted monthly from March 2015 to July 2016. Samples were collected and dried according to the usual methodology and incorporated into the VIC and VIES herbaria. In addition to VIC and VIES, we also studied the specimens form MBML herbarium. Eight species, one variety, and a new hybrid were recorded: Anemia collina, A. ×elephantensis nothosp. nov., A. ferruginea var. ferruginea, A. hirsuta, A. luetzelburgii, A. organensis, A. patens, A. phyllitidis, A. tomentosa var. tomentosa, and A. tomentosa var. anthriscifolia. Besides the new hybrid, A. tomentosa var. tomentosa is also a new record for the state. Identification key, descriptions, comments, geographical distribution and illustrations are provided for all taxa.

Highlights

Anemiaceae is a family of a single genus, Anemia Sw., with 115 species
The state of Espírito Santo, which is fully included within the Atlantic Rain Forest Domain, harbors 22 species of Anemia (Prado et al 2015, Mickel 2016)
The Atlantic Rain Forest is a hotspot of the global biodiversity (Myers et al 2000) and an important center of endemism and diversity for ferns and lycophytes (Tryon 1972)

Summary

Introduction

Anemiaceae is a family of a single genus, Anemia Sw., with 115 species. It is widespread in the Americas, southern Africa, and Madagascar, and has a few species in India and some oceanic islands (Mickel 2016). The state of Espírito Santo, which is fully included within the Atlantic Rain Forest Domain, harbors 22 species of Anemia (Prado et al 2015, Mickel 2016). Along the Atlantic Rain Forest, especially in southeastern Brazil, rocky outcrop landscapes are very common and show peculiar environmental conditions, such as high isolation, high rates of evaporation, and a discontinuous soil coverage. These features lead to specific plant adaptations and, generate distinct floristic compositions with high plant endemism rates (Porembski 2000). As part of a floristic survey of the vascular flora of Pedra do Elefante, state of Espírito Santo, Brazil, we present the taxonomic treatment of Anemiaceae
