See Fig. 2 for definitions of the four thermotolerance parameters.
LFT, leaf flushing time (D = dry season; R = rainy season); LMA, leaf mass per area; NA, data not available. The nomenclature follows the database of the Missouri Botanical Garden (W3TROPICOS; www.mobot.org).
Data are means ± s.e. for 5–9 replicates per species.
