Description from Flora of China
Bracteoles broadly obovate in outline, 10–20 × 6–15 mm, exceeding umbellule, 2–3-pinnate.
This high-altitude, short, stout plant, with characteristic, highly dissected bracteoles, is more commonly collected than the typical variety. This plant is superficially very similar to Ligusticum capillaceum and has often been confused with it. Ligusticum capillaceum is generally hirsute, especially along the leaf rachis, rays, pedicels, bracts, and bracteoles, has lacerate bracteoles with acute lobes, and greatly dorsally compressed fruit. Sinolimprichtia alpina var. dissecta is completely glabrous, has smooth-margined bracteoles with rounded lobes, and slightly laterally compressed fruit.
Alpine grassy slopes, screes, rock crevices; 3500–4800 m. SW Sichuan, SE Xizang, NW Yunnan.
