Abstract An annotated list of the pteridophytes of Brazilian Amazonia is presented, with the geographic occurrence of the species by States and Territories. The flora includes 12 families, 58 genera and 279 species, with only four species possibly en

Alice Faber Tryon became a member of the American Fern Society in 1946 and in 1978 was elected to honorary membership, a special category of membership for those who have made outstanding contributions to the study of ferns. An eminent student of fer

Tree ferns recently were identified as the closest sister group to the hyperdiverse clade of ferns, the polypods. Although most of the 600 species of tree ferns are arborescent, the group encompasses a wide range of morphological variability, from di

The phylogenetic position of Cystodium J. Sm. is studied here for the first time using DNA sequence data. Based on a broad sampling of leptosporangiate ferns and two plastid genes (rbcL and atpB), we show that Cystodium does not belong to the tree fe

Rolla Tryon, a member of the American Fern Society since 1932 and one of the twentieth century's most eminent students of pteridophytes, was born on August 26, 1916 in Chicago, Illinois. His father, a professor of American history and education at th

Premise of the study: Discovering missing ancestors is essential to understanding the evolutionary history of biodiversity on Earth. Evidence from extinct species can provide links for reconstructing intricate patterns of reticulate relationships

We examined chlL ~rxC) gene evolution using several approaches. Sequences from the chloroplast genome of the fern Polystichum acrostichoides and from the cyano- bacterium Synechococcus sp. 7002 were determined and found to be highly conserved. A comp

Tree ferns are a well-established clade within leptosporangiate ferns. Most of the 600 species (in seven families and 13 genera) are arborescent, but considerable morphological variability exists, spanning the giant scaly tree ferns (Cyatheaceae), th

The chloroplast genome of most land plants is highly conserved. In contrast, physical and gene mapping studies have revealed a highly rearranged chloroplast genome in species representing four families of ferns. In all four, there has been a rare dup
