MELO, José Iranildo Miranda de; ALVES, Marccus  and  SEMIR, João. Geographic distribution patterns of species of Euploca and Heliotropium (Heliotropiaceae) in Brazil. Rodriguésia [online]. 2009, vol.60, n.4, pp.1025-1036. ISSN 0370-6583.

Based on an analysis of specimens from seventy-one national and international herbaria, field work and specialized literature, geographic distribution patterns of the species of the genera Euploca and Heliotropium in Brazil were determinate. Four geographic patterns and eleven biogeographic patterns were detected. The center of diversity of Euploca, in Brazil, is in the Northeast region. Species of the genus Heliotropium occur generally in the South region, with the center of diversity of the genus being found in Rio Grande do Sul State. Tables, maps and a discussion about the respective distribution and biogeographic patterns uncovered in this study are presented.

Keywords : flowering plants; neotropics; biogeography patterns.
