Fire regimes play an important role in the flowering of several plant species. Frequent fires may have a positive impact by reducing dormancy levels, while fire exclusion may lead to decreased flower abundance due to competition (Coates et al., 2006). Post-fire flowering is a fire-adaptive trait that has been primarily described for Mediterranean-climate vegetation (Lamont & Downes, 2011). However, it is present in several families in different flammable ecosystems, although mostly described among monocots, such as orchids and grasses (Lamont & Downes, 2011). Grasses are less studied in this regard and may have their flowering affected by fire (Monasterio & Sarmiento, 1976), although it is not clear how fire stimulates grass flowering and how interaction between fire season (wet-and dry-season fires) and history affect grass phenology.Post-fire flowering may occur through the direct effect of heat on
