At Laredo, on tlie Lower Rio Grande, in August, 1829, Berlandier (as appears from the remains of his collections bough 

 from his widow) gathered a few specimens of a Coniposita of doubtful affinity. The specimens were not numbered, and 

 doubtless have not been distributed by him. It is to be sought on the lower part of the Rio Grande. The plant appears to be 

 the type of a new genus, which I dedicate to Dr. A. Clapp, of New Albany, Indiana, one of the most zealous botanists of our 

 Western States, and the author of an important work, entitled *' A Synopsis or Systematic Catalogue of the Medicinal Plants 



of the United States, 1852."
