Tanaecium caudiculatum is restricted to Central America. It is known from wet forests that grow in the mountains and sea level in Belize (Belize, Cayo, Stann Creek, Toledo), Guatemala (Alta Vera Cruz), and Mexico (Chiapas, Oaxaca). Phenology. Flowering: March to May, July to September; fruiting: April, June, and August. Notes. Tanaecium caudiculatum differs from other species in the genus by the caudate leaflets, simple tendrils that bear hooks (otherwise only found in the trifid tendrilled Dolichandra ; Lohmann and Taylor 2014 ; Fonseca et al. 2017 ), foliaceous inflorescence bracts, stipitate glandular trichomes in the internal ventral surface of the corolla tubes, androecium with only two fertile stamens, and fruits with sinuous margins (Tab. 1 ).
