In 1931, Alexander Eig founded the National Botanic Garden of Israel on Mount Scopus, together with Michael Zohary and Naomi Feinbrun-Dothan.
As well as his interest in the plant geography and vegetation of Israel and Jordan, from 1950 to 1965 Zohary's research paid special attention to Turkey and Iran.
[6] Zohary officially retired in 1967, but as Professor Emeritus continued his research, his final book being Plants of the Bible (1982).
[6] With Alexander Eig and Naomi Feinbrun-Dothan he organised the distribution of plant specimens from Israel in several exsiccata series.
[12] The first series issued in 1930 is entitled Flora exsiccata Palaestinae a sectione botanica Universitatis Hebraicae Hierosolymitanae edita.
