An onion family plant. It is a bulb plant. There can be one bulb or a cluster. The covering is greyish-brown. There are 2-3 leaves. The leaf stalk is 2-10 cm long and the leaf blade is 8-12 cm long by 3-9.5 cm wide. The base is wedge shaped narrowing into the leaf stalk. It tapers to the tip.
Rocky and stony places in mountains, usually on calcareous soils. Forests, shady and moist slopes, pastures and streamsides at elevations from 600-2,500 metres in China.
