Perennial, caespitose herbs, branched mostly from the base, suberect or spreading, up to 10 (-15) cm long; clothed with stellate, white, shining rough hairs. Radical leaves densely rosulate, oblanceolate or linear-oblong (rarely linear), 5-15 mm long, 1-3 mm broad, sessile, entire, apex rounded to acute; cauline leaves distant, ± similar to the basal leaves. Racemes 12-20-flowered, up to 25 (-35) mm long in fruit. Flowers c. 4 mm across, yellow; pedicels up to 7 mm long in fruit, ascending. Sepals 2.5-3 mm long, c. 1.5 mm broad. Petals c. 6 mm long, 2 mm broad, sublyrate or narrowly spathulate, shortly clawed, apex somewhat emarginate. Stamens 3-4: 4-5 mm long; smaller filaments slightly appendaged at the base; anthers c. 1 mm long. Siliculae 4-7 mm in diam., suborbicular-ovate or broadly elliptic-orbicular; valves tumid with obscurely flattened narrow margin; style (2.5-) 3-5 mm long, tapering with minute stigma; septum not veined; seeds 1 in each locule, c. 3 mm in diam., suborbicular, with a narrow, brownish wing (margin).

Fl. Per.: April -June.

Type: Turcomania, Mt. Kular, 2100 m, Litwinow 569 (W).

Distribution: Turcomania, Iran, Afghanistan and Pakistan.

Very similar and doubtfully distinct from Alyssum iranicum Hausskn ex Baumg. from which it differs by its filaments of smaller stamens appendaged at the base, and the style usually slightly longer.

It has also Peen confused with Alyssum mulleri Boiss. and Alyssum persicum Boiss., which have smaller and longer flowering and fruiting branches respectively, with other differences.
