Morphology

Halothamnus lancifolius is a sub-shrub up to 45 cm high, with blueish-green pale-striped branches. The leaves are flat, somewhat fleshy, lanceolate-triangular or linear-triangulate, and up to 43 mm long and 1,9-4,5 mm wide, decurrent at their base for 1–5 mm along the stem. The bracts and bracteoles are flat and lanceolate, the bracteoles obliquely standing off, basally with membraneous margins. The flowers are 3,8-4,8 mm long with lanceolate-oval tepals, the stigmas are rounded at their tip. The winged fruit is 9–14 mm in diameter, their wings inserting below the middle, the tepal lobes forming a steep cone. The tube of the fruit is cylindric, its bottom with deep furrow-like, linear or curved pits.[2]
