Radinosiphon leptostachya is a slender, perennial herb up to 50 cm high, growing from corms that resprout annually. Leaves narrow, 10mm. and 45 cm long. Flowering stem is normally simple. Flowers pink, and tepals are narrow, with a darker pink line in the middle of each tepal. What makes it interesting is the flowering spike that is 4-12-flowered, sometimes more. The pink to purple flower tube is quite long. It is a very variable specie.
