Derivation of the botanical name:
Zygophyllum, zygo (Greek), "joined, yoked"; phyllon, phyll, φυλλον, "leaf", foliage.
dumosus, dumos, "full of thorn bushes, bushy".
Tetraena, probably from the Greek τέτταρες (téttares), "four," suffix -ένα -ena an organic compound.
The Hebrew name: זוגן, zugan, from זוג, zug, pair, referring to the paired leaves of many of the species.
Michael Zohary (1898-1983), a pioneering Israeli botanist, suggests on the basis of its cognate with the Arabic illam that Elim in Numbers 33:9-10 was named for Zygophyllum dumosum.
Location: Nahal Shani Riverbed (red Nubbian sandstone) in the Eilat Mountains.
