F438878AFFADAF3618E1F19F9CD2FEED.taxon	discussion	Taxonomic position and affinity: — Baccharis obdeltata belongs to subgenus Baccharis on the basis of the style apex of its male florets bearing sweeping hairs of unequal size, female florets with 5 - dentate corolla apex and glabrous> 8 - costate cypselae with deciduous biseriate pappus. The new species superficially resembles the allopatric B. truncata Gardner (1848: 82) occurring in the Espinhaço range from the northerly Chapada Diamantina south to the Serra do Ouro Branco range in ironstone vegetation (canga) but not hitherto recorded from the Serra do Cipó. Both species are characterized by the obdeltate leaves with cuneate basis. However, B. obdeltata can be distinguished by the smaller leaves (4.2 – 10 mm long and 3.5 – 8 mm wide) with 3 (– 5) - dentate apex, sessile male capitula bearing fewer florets (5 – 7) and single-flowered sessile female capitula, while B. truncata has larger leaves (1 – 2 cm long and 0.8 – 1 cm wide) with truncate apex, pedunculate male capitula bearing more florets (10 – 16) and pedunculate female capitula bearing 3 – 7 florets.	en	Heiden, Gustavo, Pirani, José Rubens (2014): Two new species of Baccharis subgen.
