With a résumé that boasts the abacus-busting credential of "2,000-plus plant species discovered and documented," Swedish botanist/explorer Erik Leonard Ekman was a Caribbean habitué who took to heart Blake's wondrous line "to see a world in a grain of sand." Besides gathering specimens that now go by their hard-to-pronounce Latinate labels, Ekman also tried his hand in cartography, charting Haitian mountains and accurately calculating the height of the Carribean's highest point, Pico Duarte. Tonight, Swedish artist and former ambassador to Cuba Karin Oldfelt Hjertonsson delves into Ekman's sizable achievements with a lecture centered around her own beautifully illustrated volume, Plantae Ekmanianae.
