Abstract
ABSTRACT (PEFI algal flora: a half-century of investigation) The survey of the algal flora of the Parque Estadual das Fontes do Ipiranga (PEFI) started in 1962, with the disclosure of occurrence of 17 desmid species, collected from the São Paulo Botanical Gardens hydrophytoterium. However, in an organized way, it took place only 28 years later, in 1990, with the conception of the “Parque Estadual das Fontes do Ipiranga Cryptogamic flora”. The flora is essentially based on material gathered from the plankton, periphyton and surface sediments of the PEFI water bodies, and also included samples from trees barks, rocks, and soil. Forty-two fascicles of the algal flora have already been published, revealing 869 taxa including species, varieties and taxonomic formae. It is estimated that 95% of the local algal flora have already been surveyed and that its conclusion will be reached by the end of the year 2020.
Highlights
First publication dealing with the PEFI, Parque Estadual das Fontes do Ipiranga biota most probably was the third contribution to the knowledge of the Brazilian orchids by Schlechter & Hoehne (1926), where the authors listed, among others, 13 species for the PEFI area
Forty-six years elapsed until the publication of the first attempt ever to know the PEFI algal biodiversity
The pioneers, Bicudo & Bicudo (1962), studied material collected from the hydrophytoterium, an artificial system designed for display of aquatic plants at the São Paulo Botanical Gardens
Summary
First publication dealing with the PEFI, Parque Estadual das Fontes do Ipiranga biota most probably was the third contribution to the knowledge of the Brazilian orchids by Schlechter & Hoehne (1926), where the authors listed, among others, 13 species for the PEFI area. Forty-six years elapsed until the publication of the first attempt ever to know the PEFI algal biodiversity. In 1990 the “Flora Criptogâmica do Parque Estadual das Fontes do Ipiranga” (Ipiranga Sources State Park Cryptogamic Flora) was created divided into three sections: (1) algae, (2) fungi and lichens, and (3) bryophytes. The following information summarizes the results from the 28 years devoted to the survey of the PEFI algal flora
