Phylogenetic tree of bromeliads and their pollination syndromes. Different colours on the nodes indicate different pollination syndromes (green: entomophily, red: ornithophily, blue: chiropterophily, pink autogamous, yellow: generalist pollination). Notes: Alcantarea duarteana is not mentioned in the literature as bat-pollinated, but we consider that it possible is; however, since Siqueira Filho (2003) suggested also moth-pollination within the genus, we provisionally refer to it as bimodal. Tillandsia malzinei is referred as a species with chiropterophilous flowers; it was considered a member of the former Vriesea subg. Xiphion (currently, the accepted name would be sect. Synandra; see Barfuss et al. 2016). We describe Tillandsia heterophylla with a bimodal pollination syndrome since diurnal floral visitors could serve as pollinators, even if most of the visits are by bats (Aguilar-Rodríguez et al. 2016). The form of Pitcairnia flammea represented in this figure with chiropterophilous floral traits refers only to P. flammea var. pallida.
