This herbarium specimen was collected by Jean-Baptiste Leblond (1747-1815), who travelled throughout Martinique, Sainte-Lucie, several West Indian islands, Trinity and Tobago, Venezuela, New Grenada and Peru. Having settled in Cayenne, he conducted research on quinine for the French government and collected plants all over French Guyana (1786-1802). From 1791 on, his collections were passed on to the Natural History Museum in Paris and a few precious copies exist in Genevan herbariums. F. Stauffer
