General Description

Evergreen, medium-sized, slender lianescent herb to 1.5 m. Stem of adult plants root-climbing. Leaves distichous, scattered on climbing shoots, congested into loose fans at shoot tips where flowering occurs. Lamina oblongo-lanceolate, somewhat falcate, oblique, 11–24 by 4–8 cm, base subacute, apex acuminate, briefly apiculate, medium green above, paler below when fresh, drying uniformly chestnut brown; primary lateral veins pinnate ca 6 per side, arising alternately from either side of the midrib, running into marginal vein, interprimary veins more or less invisible, higher order venation reticulate. Petiole pulvinate apically, 6–12 cm, petiolar sheath extending to the base of the pulvinus, membranous and very soon marcescent and falling. Inflorescence 1–3 in each floral sympodium. Peduncle erect, exceeding petiole, 11–14 cm, each subtended by membranous, later papery cataphylls and the whole synflorescence subtended by several such cataphylls. Spathe oblongo-lanceolate, apex strongly rostrate, base very weakly contracted onto the stipe, limb gaping, then reflexed at anthesis, then soon caducous, ca 3 by 1.5 cm, creamy yellow. Spadix stipitate, fertile portion ca 3 by 0.5 cm, creamy at anthesis, green post-anthesis, stipe 1 cm, green. Flowers bisexual, perigone membranous, just exceeding the gynoecium. Stamens with short, broadly linear filaments, anthers shorter than filaments. Gynoecium obpyramidal, tetragonal, stylar region 2.5 by 2.5 mm, rhomboidal, truncate, stigma transverse-linear. Fruit a subglobose truncate-topped berry, green when immature, bright glossy red with black stigmatic remains when ripe.

Evergreen, medium-sized, slender lianescent secondary hemiepiphyte to 1.5 m. Stem (adult) root-climbing. Leaves distichous, scattered on climbing shoots, congested into loose fans at shoot tips where flowering occurs; petiole pulvinate apically, 6–12 cm; petiolar sheath extending to the base of the pulvinus, membranous and very soon marcescent and entirely falling; leaf blade oblong-lanceolate, somewhat falcate, oblique, 11–24 × 4–8 cm, base subacute, apex acuminate, briefly apiculate, medium green above, paler below when fresh, drying uniformly chestnut brown; primary lateral veins pinnate, ca 6 per side, arising alternately from either side of the midrib, running into marginal vein; interprimary veins more or less invisible; higher order venation reticulate. Inflorescence 1–3 in each floral sympodium; peduncle erect, exceeding petiole, 11–14 cm, each subtended by membranous, later papery cataphylls and the whole synflorescence subtended by several such cataphylls; spathe oblong-lanceolate, apex strongly rostrate, base very weakly contracted onto the stipe, spathe limb gaping, then reflexed at anthesis, then soon caducous, ca 3 × 1.5 cm, creamy yellow; spadix stipitate; fertile portion ca 3 × 0.5 cm, creamy at anthesis, green afterwards; stipe ca 1 cm, green; flowers bisexual, perigone membranous, just exceeding the gynoecium; stamens with short, broadly linear filaments; anthers shorter than filaments; gynoecium obpyramidal, tetragonal, stylar region 2.5 × 2.5 mm, rhomboidal, truncate, stigma transverse-linear; fruit a subglobose truncate-topped berry, green when immature, bright glossy red with black stigmatic remains when ripe.

Diagnostic Description

Immediately recognizable in the dry state in drying chestnut brown (badius in Latin, whence the trivial epithet). Living plants can be confused with A. marcesovaginata (see above) but differ in the erect (not spreading to declinate) peduncles exceeding the petiole of the subtending foliage leaf, and the petiolar sheath reaching the base of the distal pulvinus.
