|   Derivation of the botanical name: Arabidopsis, arabis, a Greek word used for "mustard" or "cress," and the Greek word for Arabia; resembling Arabis. thaliana, after Johannes Thal (1542 - 1583), who discovered this species in the Harz Mountains and originally called it Pilosella siliquosa. Stenophragma, stenos στενοϛ narrow, straight; phragma, a fence or screen; a narrow fence. The Hebrew name: Tudranit comes to indicate a kind of small tudra (Sisymbrium), although systematically the genus is close to Arabis rather than Sisymbrium.The name "Tudra", as the plant's Hebrew name, was first mentioned in a dictionary for the plants of the Land of Israel published by the Hebrew Language Committee in 1946, where it appears in the pronunciation: "Tudara" which was later renamed "Tudra".
