The flowers are wide with pale yellow sepals and petals and a golden yellow labellum. The fused infertile stamens form a large petaloid labellum that often functions to attract pollinators. The outer staminodes are shorter than the labellum. In the case of "A." Veitchii both the petals, sepals, and labellum move inward. The rather small glabrous labellum has a green color. The third (medial) petal forms the highly modified labellum. The labellum is joined stiffly to the column and has three lobes. Pattern of labellum colouration is quite variable. The lower labellum is pale red and is much shorter than the upper petals. As is usual in orchids, one petal is highly modified as the central labellum. The labellum is long and has three lobes. The labellum is long and wide with three lobes. The labellum is long, wide and has three lobes. The labellum of the orchid resembles a female thynnid wasp in shape, colour and scent. There is a large yellow callus near the base of the labellum.
