Chondrilla juncea

Perennial herb to 1.2 m high. Plants with deep taproot and creeping roots that may form new plants. Leaves in rosette lobed, usually hairless, 4–20 cm long, 1.5–5 cm wide; narrow-leaf, broadleaf and intermediate-leaf forms are recognised in Australia, primarily based on shape of basal leaves, leaves die early in the flowering period and plants are then virtually leafless over summer.
