[HVPOGYXOUS EXOGENS. 



All the species occur in equinoctial America, except the doubtful genus Antholoma, 

 which is a native of New Caledonia. 



They are handsome and curious plants, remarkable for their singular cucullate bracts. 

 The stem, root, and leaves of Marcgravia umbellata are regarded in the West Indies as 

 diuretic and antisiphylitic.
