Abstract: Chromosome numbers are presented for 20 Brazilian species of cerrado vegetation, belonging to 12 families: Annonaceae (Xylopia aromatica, 2n=16), Bombacaceae (Eriotheca gracilipes, 2n=99; E. pubescens, 2n=ca.270), Caryocaraceae (Caryocar brasiliense, 2n=46), Cochlospermaceae (Cochlospermum regium, 2n=36), Erythroxylaceae (Erythroxylum campestre, 2n=24), Leguminosae (Acosmium subelegans, 2n=18; Andira humilis, 2n=22; Hymenaea stigonocarpa, 2n=24), Malpighiaceae (Banisteriopsis sp, 2n=40, Byrsonima coccolobifolia, 2n=24; B. intermedia, 2n=24; B. verbascifolia, 2n=24; Peixotoa sp, 2n=30), Myrtaceae (Compomanesia pubescens, 2n=22), Rubiaceae (Alibertia sessilis, 2n=22), Sapindaceae (Magonia pubescens, 2n=30; Serjania erecta, 2n=24), Solanaceae (Solanum lycocarpum, 20=24) and Styracaceae (Styrax ferrgineus, 2n=16). The counts are new for 12 species and four genera. Evolutionary trends are discussed for some species, including the hexaploid origin of a pubescens from E. gracilipes.
