The expeditions were carried out in two Brazilian environments: 1) semi-arid region, know as 'caatinga' (thorny forest), northeast Brazil and 2) savanna or 'cerrados' region, central-west Brazil. In the 'caatinga' expeditions, two collections were performed (21-22/Dec/2005 and 15-16/Feb/2006) in the central western of Bahia state, traveling around 1500 Km, where 18 points of collections were recorded and 7 species found: 1) M. caerulescens (5 records); 2) M. diamantinensis (1); 3) M. dichotoma (6); 4) M. glaziovii (1); 5) M. jacobinensis (1); 6) M. maracasensis (3); and 7) cassava 'sete anos' (1). In the savanna's expedition, one colection was accomplished (17-20/Apr/2006) in the plateau of Brasilia Federal District and Goias state, traveling around 1100 Km, where 28 points were recorded, with 17 species found: 1) M. anomala (2); 2) M. cecropiaefolia (1); 3) M. falcata (1); 4) M. fruticulosa (2); 5) M. gracilis (1); 6) M. irwinii (1); 7) M. mossamedensis (1); 8) M. nana (1); 9) M. pentaphylla (1); 10) M. salicifolia (1); 11) M. sparsifolia (1); 12) M. stipularis (1); 13) M. tomentosa (2); 14) M. tripartita (2); 15) M. triphylla (1); 16) M. tristis (1); and 17) M. violacea (8). Depending on the plant architecture and vegetative stage, cuttings, mature fruits or seedling were collected. The handling for propagation and field establishment of the collected material are underway.1 aMENDES, R.1 aVIEIRA, J.1 aRODRIGUES, A.1 aCARVALHO, P. de  tIn: SCIENTIFIC MEETING OF THE GLOBAL CASSAVA PARTNERSHIP, 1., 2008, Ghent.
