Derivation of the botanical name:
Alha'gi, Arabic for "pilgrim".
Alhagi manna (Persian and Arabic tar-angubin, also known as terendschabin and Taranjabiti, Taranjabiti) is the produce of Alhagi maurorum.
This manna occurs in the form of small, roundish, hard, dry tears, varying from the size of a mustard seed to that of a coriander, of a lightbrown colour, sweet taste, and senna-like odour. The spines and pods of the plant are often mixed with it.
Tamarisk manna (Persian gaz-angubin, tamarisk honey) exudes in June and July from the slender branches of Tamarix gallica, var. mannifera, in the form of honey-like drops, which, in the cold temperature of the early morning, are found in the solid state. This secretion is caused by the puncture of an insect, Coccus manniparus.
The manna of the Biblical narrative, notwithstanding the miraculous circumstances which distinguish it from anything now known, answers in its description very closely to the tamarisk manna.
