Easton's Bible Dictionary (1897)
Our Lord was crowned with a, in mockery by the Romans (Matt. 27:29). The object of Pilate’s guard in doing this was probably to insult, and not specially to inflict pain. There is nothing to show that the shrub thus used was, as has been supposed, the spina Christi, which could have been easily woven into a wreath. It was probably the thorny nabk, which grew abundantly round about Jerusalem, and whose flexible, pliant, and round branches could easily be platted into the form of a crown.
Smith's Bible Dictionary (1863)
(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. ”—Alford.
