Morphology

Halothamnus iranicus is a sub-shrub up to 45 cm high and 100 cm in diameter, with blueish-green branches. It smells unpleasantly like rancid butter. The leaves are linear to triangular-ovate, and up to 11 mm long. The flowers are at 1–6 mm distance from each other, 3,2-4,2 mm long, longer than their bract and bracteoles, with oblong-ovate tepals. The stigmas are tapering towards the apex. The winged fruit is 7–11 mm in diameter, their wings inserting at 1/3 of the fruit height. The fruit tube is nearly cylindrical, with narrow, sharp-edged peripheral rim and small, ovate pits.
