Tainia trinervis, commonly known as the ribbon orchid,[2] is an evergreen, terrestrial plant with crowded pseudobulbs, each with a single smooth, shiny leaf and up to fourteen greenish to yellowish flowers with red or purplish stripes in the middle. It is found in tropical Southeast Asia, New Guinea and northern Australia.
Tainia trinervis is an evergreen, terrestrial herb that has thin, crowded, dark green pseudobulbs. Each pseudobulb is 40–70 mm (2–3 in) long and 7–10 mm (0.3–0.4 in) wide and has a single smooth, shiny, dark green leaf 100–160 mm (4–6 in) long and 40–60 mm (1.6–2.4 in) wide on a stalk 30–50 mm (1–2 in) long. Between three and fourteen greenish white to yellowish resupinate flowers 13–18 mm (0.5–0.7 in) long and 20–25 mm (0.8–1 in) wide are well-spaced along a thin flowering stem 200–300 mm (8–10 in) tall. The sepals are 9–12 mm (0.4–0.5 in) long and 3–4 mm (0.12–0.16 in) wide with their tips curved back. The petals are a similar size to the sepals but project forwards. The labellum is 7–8 mm (0.28–0.31 in) long and 5–6 mm (0.20–0.24 in) wide and has three lobes. The middle lobe has three purple ridges and a curved tip. The side lobes curve upwards. Flowering occurs from September to November.[2][3][4]
