Johannes Eugenius Buelonv Warming was born on Mano, Jylland, 

 Denmarlc, the 3rd of November, 1841, received the degree Ph. D. 

 in 1871, became docent at the University of Copenhagen in 1874, 

 at Stockholm, 1882 — 6, and was appointed professor and director 

 of the Botanical Garden at Copenhagen, in 1887. 



He undertook in 1863 a journey to Brazil, where he remained 

 for three j^ears. The book published on Lagoa Santos after his 

 return home, placed him at once as one of the leading phytoge- 

 ographers of the world. In 1884 he and Theodor Holm joined 

 the Fylla Expedition to Greenland, and in 1891 and 1892 he un- 

 dertook a botanical exploration of the West Indies and South 

 America. He was accompanied by Holger Jorgen Lassen, and 

 Mr. Levissen, a forester, and visited Barbados, Trinidad, Venezu- 

 ela, Porto Rico, and the Danish West Indies. During these trav- 

 els of his he gathered extensive material and knowledge, which 

 he used in his phytogeographical and ecological works. He drew 

 also from the work done in the West Indies by Borgesen and 

 Paulsen. The works that treat more or less of the North Amer- 

 ican Flora are the following:
