Crataegus x sinaicus

"Crataegus × sinaica" is a hawthorn that originated as a hybrid between two other hawthorn species, "C. azarolus" in series "Orientales" and "C. monogyna" in series "Crataegus". It grows in the central and eastern parts of the Mediterranean region on rocky mountain slopes. In Egypt it grows in the mountains near Saint Catherine in South Sinai, where it is known as Za'rur or Za'rur al-awdiyah.
