Crown of thorns,

( Matthew 27:29 ) Our Lord was crowned with thorns in mockery by the Roman soldiers. Obviously some small flexile thorny shrub is meant perhaps Capparis spinosa. "Hasselquist, a Swedish naturalist, supposes a very common plant naba or nubka of the Arabs, with many small and sharp sines; soft, round and pliant branches; leaves much resembling ivy, of a very deep green, as if in designed mockery of a victors wreath." --Alford.
