Iris potaninii var. arenaria Doronkin 
Iris psammocola is a species in the genus Iris, it is also in the subgenus of Iris and in the Pseudoregelia section. It is a rhizomatous perennial, from China. It has grass-like leaves, short stems, yellow flowers. It is cultivated as an ornamental plant in temperate regions.
It has narrow, linear leaves, that can grow up to between 8–13 cm (3–5 in) long, and between 0.2 and 0.4 cm wide. They have a pointed end.
It has a very short slender stem, that can grow up to between 3–4 cm (1–2 in) tall.
The stems hold 1 terminal (top of stem) flower, blooming between April and May.
Like other irises, it has 2 pairs of petals, 3 large sepals (outer petals), known as the 'falls' and 3 inner, smaller petals (or tepals), known as the 'standards'. The falls have an obovate limb (part of the petal beside the stem), they are 4 cm (2 in) long and 1.5 cm wide. In the centre of the petal is a beard. The erect standards are oblanceolate and 3.5 cm (1 in) long and 4 cm wide.
After the iris has flowered, it produces an seed capsule which has not been described.
As most irises are diploid, having two sets of chromosomes, this can be used to identify hybrids and classification of groupings. Nothing has been reported currently as of August 2015, about a chromosome count of the iris.
It is commonly known in China as 'Sandy iris'.
As of August 2015, Iris psammocola is not yet an accepted name by the RHS.
