Scrub, alpine meadows, streamsides; 4000–4500 m. SE Xizang (Zayü). 
This rather poorly known taxon is recorded only from a few specimens. It resembles Trachydium roylei and T. tibetanicum, but differs in having 2–3-lobed or pinnate bracteoles (rarely entire) and vittae 3 or 4 in each furrow and 6–8 on the commissure.
