Barbella pendula is not common in the flora area but may be abundant locally. The delicate, yellowish green plants dangle in conspicuous, tangled festoons in their ravine-bottom habitat. The striking habit of B. pendula and the somewhat dimorphic branch leaves, including the distal with 1-seriate, filiform apices, make the species unmistakable. Barbella pendula has been reported from Florida, but the collections are either Papillaria nigrescens or of uncertain provenance. Perigonia have never been found in specimens (some abundantly fruiting) of B. pendula from the flora area.
