People take a boat to see giant water lilies (Victoria amazonica) - known as Yakare Yrupe in Guarani - which appear every three to four years in great numbers and size (more than a metre and a half in diameter), in the Paraguay River in Piquete Cue just north of Asuncion, on January 8, 2018. Water lilies are seen every year but not in such quantities and size and locals treat them as a national treasure. / AFP PHOTO / Norberto DUARTE
