Notes:— There are three specimens of Ficus gigantosyce labelled as type in the Herbario Nacional Colombiano; i.e. COL 3915, COL 3916, COL 407615. Since Dugand (1942) did not label these specimens as being part of the same specimens they are considered as duplicates and a lectotype must be chosen (Art. 9.1 and 9.2). We chose the specimen COL 3916 because it has stipules and a syconium, which are informative characters.
