Description

Pendent epiphytic herb; stem up to 40 cm long, leafy towards the apex, woody below this; roots many, c. 2 mm in diameter.Leaves distichous, dark green, 4.5-9 cm × 4-9 mm, linear to ligulate, sometimes falcate, acutely and very unequally 2-lobed at apex, one lobe often ± absent, the other to 15 mm long.Inflorescences 1-flowered, borne opposite the leaf axils, arising from the same place in successive years and often forming a short, woody spur.Peduncle 5-17 mm long, filiform; pedicel and ovary twisted, 6-7 mm long; bracts 1-2 mm long.Flowers orange-straw coloured, 17-20 mm in diameter.Sepals 6.5-9 × 1.5-3 mm, lanceolate, acute; petals similar but slightly smaller.Lip boat-shaped, 5-8 × 3-5 mm, including a 2 mm long acumen; spur 8-9 mm long, slender but slightly swollen at the tip.Column 1-1.7 mm long.

Notes

Some specimens from Mozambique (Luja 467 and Cambitzis s.n.) may belong here; they differ from typical A. stolzii in having a long (17-24 mm) straight, erect spur which is not swollen at the apex, but otherwise agree with this species.
