Aaronsohnia factorovskyi

Aaronsohnia factorovskyi is a species of annual or short-lived perennial herb in the family Asteraceae (the daisy family), order Asterales. It belongs to the genus Aaronsohnia, a small genus of plants in the tribe Anthemideae — the same tribe that includes chamomiles and yarrows — native to the arid and semi-arid regions of the Middle East and North Africa. The genus was named in honor of Aaron Aaronsohn, a prominent early twentieth-century botanist and agronomist known for his work on the wild ancestors of cultivated wheat in the Fertile Crescent. The species epithet factorovskyi commemorates another botanist or collector associated with the study of the regional flora. Aaronsohnia factorovskyi is a small herbaceous plant adapted to desert, semi-desert, and rocky steppe environments where rainfall is sparse and soils are typically well-drained and poor in organic matter. Like most members of Asteraceae, it produces composite flower heads — the characteristic 'daisy flower' structure — in which what appears to be a single flower is actually a tight cluster of many small individual florets. The outer ray florets typically bear ligulate ('strap-shaped') petals, while the inner disc florets are tubular and complete, containing both stamens and a pistil. Aaronsohnia factorovskyi is likely found in the deserts and rocky plains of Israel, Jordan, the Sinai Peninsula, or adjacent regions, areas historically explored by Aaronsohn and other early botanists in the eastern Mediterranean. Conservation status and precise distribution require further botanical surveys in its arid native range.
