1 The plants of the family Begoniaceae collected during the biological ex- 

 ploration of Panama, undertaken a number of years ago under the auspices 

 of the Smithsonian Institution, were placed in the hands of Mr. Casimir de 

 Candolle, of Geneva, for determination, together with unidentified specimens 

 from other parts of tropical America. The present paper, manuscript of 

 which was received some time before Mr. de Candolle's death, contains 

 description of new species based upon a part of this material. Of the species 

 described as new, 14 are from Panama, and one each from Guatemala, Costa 

 Rica, and Ecuador. — Frederick V. Coville.
