In Omani studies: Miller & Morris (1988) wrote that: "Other plants which provide rich feed for livestock at this time are given the same name, called ḥerúm ź a‘ alÍg, meaning 'plant of the camel calves', such as the Commelina spp., Ecbolium violaceum, and Termnus repens - small herbs which shoot up at the beginning of the rains, and are heavily browsed by all livestock". (Ref. Plants of Dhofar).
