Friedrich Carl Lehmann

Friedrich Karl Lehmann (27 November 1850 - 23 November 1903) was a German Consul to Colombia, mining engineer, amateur botanist and mycologist, and botanical collector.
Lehmann conducted explorations in search of specimens of flora in the countries of Ecuador and Colombia over three decades, sending collected material to herbariums in Berlin Dahlem, Kew, and St. Petersburg. In 1903 he led an expedition to Popayan, Colombia and passed through most of the provinces of Ecuador, in a search for orchids.[1]
