1.2. Adenocalymma marginatum ( Chamisso 1832: 695) De Candolle (1845: 200) ( Fig. 5 a–c ).

Diagnosis:— Adenocalymma marginatum can be identified by the chartaceous leaflets with coriaceous margins (vs. membranaceus leaflets without coriaceum margins in A. bracteatum and A. paulistarum ), by the ovate and straight prophylls of the axillary buds (vs. triangular prophyll in A. bracteatum and curved prophylls in A. paulistarum ).

Reproductive Period:— Flowering throughout the year, fruiting in March, May and December.

Distribution and Habitat:— It occurs in Argentina, Brazil, Paraguay, and Uruguay ( Lohmann 2010, Lohmann & Taylor 2014). Within the study area, it was registered in Céu Azul, Matelândia/Serranópolis, Capanema, Foz do Iguaçu, and in the PARNA Iguazú , abundant in anthropized areas, such as the “Picada Benjamin” in Capanema , where the border of the PARNA Iguaçu is near crops and private properties, and the “Estrada do Colono” which is in restauration process, but was an open road that used to cross the Park. Also common near the BR-469 borders in Foz do Iguaçu, a highly disturbed area for tourism.
