'Frederick Michael Liebmann (1813-1856), a Dane, was sent by the Danish 

 Government to Mexico in 1840, in company with a gardener. Rathsack, to make 

 scientific collections, especially of living plants and seeds for the botanical 

 garden of Copenhagen. He landed at Veracruz in February, and with Kar- 

 winsky he explored that State, making his headquarters at Mirador. Later 

 he visited Puebla and Oaxaca, and in 1843 he returned to Copenhagen witt; his 

 collections, which consisted of 40,000 botanical specimens. He was appointed 

 professior of botany at Copenhagen in 1845 and director of the botanical gar- 

 den in 1849. He published numerous papers based upon his collections, and 

 after his death Oersted also published descriptions of some of the new species 

 discovered. His plants were distributed to many of the herbaria of Europe 

 and the United States.
