Derivation of the botanical name:

Tribulus, an instrument resting on three of its iron prongs, while a fourth projected upward, thrown on the ground to impede an enemy’s cavalry, a caltrop. Transfer from its resemblance in form; a kind of thorn or thistle, land-caltrops: Tribulus terrestris, Linn.

terrestris, of or belonging to the earth or land; growing on the ground.
caltrop is derived from the Latin calcitrapa (foot-trap).
The Hebrew name: קוטב, kotev, from Arabic: kotaba.

  • The standard author abbreviation L. is used to indicate Carl Linnaeus (1707 – 1778), a Swedish botanist, physician, and zoologist, the father of modern taxonomy.

The Greek word τρίβολος, Tribulus, meaning “a prickly plant”, refer to thistles. Dardar, דרדר, translated τρίβολος, trı́bolos in the Septuagint: Genesis 3:18; Hosea 10:8, English Versions of the Bible “thistle”. τρίβολος also occurs in the New Testament: Matthew 7:16, “thistle”; Hebrews 6:8, the King James Version “briers” the Revised Version (British and American) “thistles”.

The Hebrew word dardar, דרדר is a species of the star thistle, perhaps the Centaurea iberica. Centaurea iberica is one of the commonest weeds of the eastern Mediterranean. see: Thorns and Thistles in the Bible
