Zygophyllum Dumosum is one of the flower images identified on the Shroud by Avinoam Danin, a botany professor at the Hebrew University of Jerusalem and a leading authority on the flora of Israel, along with Uri Baruch, a pollen specialist with the Israel Antiquities Authority.
The identification of Zygophyllum Dumosum confirmed some previous floral image identifications by Oswald Sheuermann, a German physicist, and Alan Whanger, a professor at Duke University.
Note: Some of the pollen identification has been challenged because of inaccurate chain of evidence record keeping. And image identification of the flowers is highly subjective. Image identification of Zygophyllum Dumosum is made from photographs of the Shroud. The cloth has stains, dirt, bloodstains and wrinkles that introduces visual anomalies. Photographic film, due to grain limitations, may not perfectly capture subtle details. Enhancement of contrast and brightness of the photographs, which is necessary, may distort the picture, as well.
