It is a small plant which makes foliage resembling a miniature Iris graminea (in Spuria section), the buds do not show up, and the flowers suddenly open up flat at the height of leaf tips, It has thin long rhizome. Each tuft of six or eight slender green leaves produces a single stem. The leaves  can reach 20–25 cm in length and around 3 mm in width. They are visibly ribbed (3 raised ribs). The stem reaches up to 8 cm (4–6 inches) in height, with a single, two-flowered (bud) spathe. The spathe valves are entirely green when the flower is expanded, and though they are an inch or more in length, yet the pedicel (stem of the flower) is even longer, so that the ovary is exposed above the spathes. The perianth tube is very short at 4 mm long. The flower buds are yellow, but the flowers blooming in April, range from  light-blue, to creamy-white or pale yellow. They are about 3 cm in diameter, and have a small yellow patch in the centre of the falls, which deepens to green on the haft, the outside of falls are yellow, shading to green in the lower half (the haft near the stem). The two flowers (on the double spathe) open together for about 4 days, the first flower lasting for about 10 days in good conditions. Capsules and seeds have not seen or described.
