the extensive herbarium of the New York Botanical Garden. He 

 has furthermore brought to the attention of the writer a well marked 

 and highly interesting novelty from Jamaica, E. hammatodadum, and 

 has consented to join in its publication. Mr. W, R. Maxon of the 

 United States National Museum has sent to the Gray Herbarium for 

 study many Eupatoricac collected by himself in Panama, by Prof. H. 

 Pittier in Costa Rica, Panama, Colombia, and Venezuela, and by 

 Bros. Apollinaire & Arthur in the neighborhood of Bogota. Mr. T. S. 

 Brandegee has sent man}' Eupatoriums collected by Dr. C. A. Purpus, 

 chiefly from Vera Cruz and vicinity. Prof. C. F. IVIillspaugh of the 

 Field Museum has brought to the writer's attention and lent for study 

 a small but interesting collection made by Dr. Arthur Schott in 

 Colombia just south of the Panama boundary. Miss Mary A. Day, 

 librarian of the Gray Herbarium, has assisted in the bibliography and 

 proof-reading, and in tracing many minor geographic localities of 

 which the correct placing has involved much discriminating search in 

 maps, atlases, and works of travel of very different periods. IMr. 

 Percy Wilson has most kindly contributed a detailed transcription 

 of the field data accompanying the Eupatoriums and INIikanias of the 

 H, H. Smith collection from the region of Santa Marta. To all these 

 persons the writer wishes here to express his thanks and cordial appre- 

 ciation of their valued aid.
