Porcion sur-oeste, entre la sabana y el salto arriba del campamento, este del tributario del Río Marajano, Cerro Jaua, Meseta del Jaua, Estado Bolívar, Venezuela, 1800 m alt, 26 Feb 1974, Julian A. Steyermark, Victor Carreno Espinoza & Charles Brewer-Carias 109535 (holotype VEN). Paratype. Cumbre, selva de galeria al borde del tributario del Rio Marrajano, Cerro Jaua, 1750-1800 m alt, 22-28 Feb 1974, Steyermark, Carreno Espinoza & Brewer-Carias 109766 (VEN). Tapeinostemon jauaensis is bracketed in our key with T. rugosum, but this pairing does not indicate close relationship. Indeed, even with little material at hand for both, there seems to be in common between them only the state of short decurrent petioles.
