Description
The species was first described as Aaronsohnia factorovskyi, and was named after the botanists Aaron Aaronsohn and his colleague Eliezer Faktorovsky. [3] However, the plant was actually discovered by Otto Warburg and Alexander Eig in 1927. In 2022, Christoph Oberprieler and Robert M. Vogt moved the species to genus Otoglyphis . [1] [4]
O. factorovskyi is found from central Israel to Iraq and the Arabian Peninsula, [5] and in the Judean Desert, the Samaria region, and certain parts of Jordan. [6]
An annual plant, from late October to early April, the plant grows its foliage, and from early to mid-January, the plant blooms. Its fruit, being two achenes, starts growing in late February and is ripened in early April, which leads to seed dispersal later. [7] It grows in desert depressions and wadis, on sand, sandy gravel, loam, and clay soils and occasionally on rocky slopes and silty plains from 10 to 410 meters elevation. [1] The more water the plant receives, the more inflorescence is found on it, [7] and during heavy rain in wadis, the O. factorovskyi thrives. [8] [9] Yellow inflorescenses contain many tubular flowers, which are supported by long peduncles, [7] and the bulb part tastes like chestnuts when cooked. [10] Its pollen grains were found to be roughly spherical. [11]
O. factorovskyi is known to have medicinal properties, and was often used by the residents of the Showbak region in Jordan. [12] The extract from the plant, combined with silver nanoparticles, was found to be antibacterial. [13]
