Table 1 in Taxonomic updates in Amphitecna (Bignoniaceae): A new Mexican species and the re-establishment of the giant-leaved A. megalophylla

Table 1. Species currently recognized in Amphitecna (Bignoniaceae) and their respective geographical distribution. The species are ordered by the morphological groups recovered in the clustering analysis. Amphitecna latifolia (from the A. molinae group, cluster “A”) was excluded because it is the only broadly distributed species. NM = Northern Mesoamerica; SM = Southern Mesoamerica.
