It is sometimes called guyalone in English. The plants are xerophytic evergreen shrubs and are known to accumulate aluminum.

Petenaea cordata (from northern Central America) was first described in Elaeocarpaceae and later placed in Tiliaceae, but most authors have been uncertain about its familial affinities. It was considered a taxon incertae sedis in the Angiosperm Phylogeny Group classification (APG III). Molecular analyses based on a recent collection from Guatemala indicate a distant, weakly supported sister-group relationship to the African genus Gerrardina (Gerrardinaceae; Huerteales). As no obvious synapomorphies exist for Gerrardina and Petenaea, the new monogeneric family Petenaeaceae was proposed. The pol
