Bignonia Liana

Overview

The bignonia liana (Fridericia chica, formerly Arrabidaea chica) is a woody climbing vine in the family Bignoniaceae — the same family as the familiar trumpet-creepers and catalpa trees. It clings to and climbs host trees using tendrils, extending from forest floor to upper canopy wherever light penetration allows. Its most conspicuous feature is a flush of tubular, orange-red to pink flowers — typical of Bignoniaceae pollination biology — that attract hummingbirds and large bees.

The species was long known under the genus name Arrabidaea until a 2004 phylogenetic revision by botanist Lúcia Lohmann reassigned much of that genus to Fridericia, reflecting resolved evolutionary relationships within the family. The old species name chica — also the common name in Spanish — derives from an indigenous Carib term for the plant’s dye.

The leaves, when boiled, yield a vivid orange-red pigment long used by Amazonian indigenous peoples for body and facial decoration. The dye has documented cosmetic and ceremonial uses across a wide range of Amazonian societies.

Why Tortuguero

Tortuguero’s canal margins and secondary forest patches provide the precise conditions F. chica favors: disturbed or semi-open forest edges where the liana can reach light. Along the canal banks, where periodic flooding and boat traffic maintain broken canopy, bignonia lianas are part of the characteristic tangle of climbing vegetation that lines the waterways. When in flower, the orange-red clusters are visible from the water and attract hummingbirds — particularly hermits — making them a useful search image for birders on canal tours.

The family Bignoniaceae is disproportionately prominent in the Tortuguero flora: large-flowered lianas and canopy trees in this family are among the most visible flowering plants in the park, and F. chica at the forest edge is often the first introduced to visiting naturalists.

How to see them (honestly)

• Where: forest margins and secondary growth along canal banks. Most visible from the water when in flower, when the orange-red inflorescences stand out against the green backdrop.
• When in flower: typically at the start of the wet season (May–June) and in the dry-to-wet transition; sporadic flowering occurs year-round.
• What to look for: a climbing vine with opposite, compound leaves (usually one pair of leaflets with a terminal tendril); orange-red tubular flowers in clusters when blooming. Vegetatively, the opposite leaflets with a tendril are diagnostic among canopy-margin climbers.
• Associated wildlife: hummingbirds — including long-billed hermits — visit the flowers; bats may visit after dark.

Status note

No formal IUCN assessment exists for this species; it is considered secure given its wide neotropical range and tolerance of secondary habitats. It is not threatened by forest loss in the way that strict old-growth specialists are; if anything, selective logging and edge creation tend to benefit it. In Tortuguero, the species is a reliable component of canal-edge vegetation with no conservation concern.
