Appearance
It is a deciduous shrub or small tree growing to 3–4 m tall. The shoots are zig-zagged, with a leaf and two stipular spines on the outside of each kink. The leaves are oval, 2–5 cm long and 1–4 cm broad, glossy green, with an entire margin. The fruit is a dry woody nutlet centred in a circular wing 2–3.5 cm diameter.
Naming
The name reflects an old legend that the spiny branches were used to make the crown of thorns placed on Christ's head before his crucifixion.References:
