*The extensive collection of Isaac F. Holton was one of the first made in Colom- 

 bia and has never been studied ; a full set of the collections is in the Torrey herbarium ; 

 Holton went out from Middlebury College on a twenty months' trip through Colombia. 

 He afterwards published an account of his travels which bears the following title : New 

 Granada : twenty months in the Andes. New York, 1857. A copy has recently been 

 added to the library of the New York Botanical Garden.
