Hab. Assumption, State of Paraguay, (not Island of As- 
sumption, as given by Mr. Moore), M. Gibert. 
A very delicate and beautiful species, of which I have seen 
only one fine specimen, kindly sent me by M. Gibert, a 
gentleman chiefly resident at Monte Video, but who has 
contributed much to our knowledge of the Nat. History of 
Paraguay, and to whom I desire to dedicate the species. It 
belonging to a family of plants, of which there are compara- 
tively few representatives in Paraguay, judging from the 
proportion of them with other plants that have yet come to 
us. It will rank near the well-known Aspl. cicutarium.
