1 The descriptions of new species presented herewith are taken from an extended 

 manuscript account of the Panamanian and Central American species of Piper pre- 

 pared by the late Casimir de Caxdolle, largely upon material in the U.S. National 

 Herbarium, the Central American specimens having been included in material sent 

 to M. de Candolle for elaboration in connection with his study of the Piperaceae 

 collected during the recent biological survey of Panama under the auspices of the 

 Smithsonian Institution. — William K. Maxox, U.S. National Museum.
