The two preceding papers of this series were published in 
this journal November, 1889, and October, 1890. The present 
paper is a report upon the Umbelliferae of Mr. John Donnell 
Smith's third distribution of Guatemalan plants. Most of 
the species were sent by H. Th. Heyde and Ernst Lux, who 
have made extensive collections for Mr. Smith. We have 
previously reported upon Guatemalan Umbelliferze in this 
journal for January and October, 1890.
