Leaves linear, 15-35 × 0.5-1.5 mm, 1-veined, margin sometimes very sparsely papillate-ciliolate, apex acute or acuminate. Inflorescences racemelike, many flowered; bracts inserted at tip of pedicel, linear-lanceolate; pedicel to 3.5 mm, sometimes almost absent; bracteoles 2, linear, 2-6 mm, margin rugose. Perianth 5-merous, greenish white, 2.5-3 mm; tube tubular, lobes acute, apex incurved, adaxially inconspicuously hairy. Stamens not exserted. Ovary sessile. Style very short.

The ethyl acetate, chloroform extracts, and the two flavonoids kaempferol 1 and kaempferol-3-O-glucoside 2 isolated from whole plants of Thesium chinense Turcz were investigated for their antiinflammatory and analgesic activities.
