This paper studied the fern and lycophyte flora of Rio Grande do Norte in northeastern Brazil, using a floristic survey approach to compile spore-bearing vascular plant records across the state. The authors documented 334 records representing 64 species in 23 families, including 14 species recorded for the first time in the state, and they analyzed ecological and distribution patterns while identifying collection gaps and sampling biases. A major limitation acknowledged is that the observed patterns are strongly shaped by uneven sampling effort, particularly the concentration of collections in the Atlantic Forest and Caatinga. The paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match in the upstream search index.

Abstract

Brazil, with its vast territory and climatic diversity, harbors a rich biodiversity of plants, including ferns and lycophytes. However, these groups remain understudied in northeastern Brazil, particularly in the state of Rio Grande do Norte. This study provides a comprehensive floristic survey of spore-bearing vascular plants in Rio Grande do Norte, documenting 334 records encompassing 64 species across 23 families. Fourteen species are recorded for the first time in the state. Collection gaps and sampling biases were identified, revealing ecological and distribution patterns. The analysis highlights a significant concentration of sampling effort in the Atlantic Forest and Caatinga, influenced notably by seasonality and water availability. This study underscores the need for conservation efforts targeting fern and lycophyte species and identifies critical areas for future research.
