is of considerably greater proportions than Professor Helmsley 

 reports in the botanical volumes of the Biologia Centrali-Americana. 

 Only a patient overhauling of the whole herbarium can definitely 

 settle the question of the species in this collection. A few genera in 

 Leguminosae revealed several plants which I have incorporated in the 

 following list. 



Dr. Geo. F. Gaumer has continued his collections during the 

 past year. These, so far as determined, form the basis of this con- 

 tribution, and appear in the text in parenthesized numerals in the 

 body type the numbers of other collectors being in italics. 



To the above collections are added, in the following list, a few 

 hitherto unclassified numbers collected by the author in 1887, and in 

 1895 while a member of the Allison V. Armour expedition, and the 

 remaining numbers of Sr. Porifirio Valdez' century of "Medicinal 

 Plants" collected in 1895. As heretofore, the species appearing in 

 black-face type are new to the region covered by these publi- 

 cations. 



Those specialists who have kindly contributed to the knowledge 

 of the species, are credited under the orders they have worked.
