Botanist and taxonomist (1912-1992).
António Rodrigo Pinto da Silva (Porto, 13 March 1912 – Lisbon, 28 September 1992), often referred to as A.R. Pinto da Silva or P. Silva, was a Portuguese botanist who distinguished himself as a taxonomist and phytosociologist when he collaborated with Swiss botanist Josias Braun-Blanquet and also with Pierre Dansereau. His studies on taxonomy and floristic yielded a substantial number of new taxa and a better knowledge about many plants and its nomenclature. He organized the Estação Agronómica Nacional's (National Agronomic Station) herbarium, which he rose from 3000 to almost 100,000 entries.
