Laffitte (2012, 2025) treats Al-Rumh as an alternative name for Muphrid (η Boo) in the constellation al-Simākān, The Two Supporters, one armed, one disarmed:

• Rumh. Ar. الرمح al-Rumḥ, ‘the Spear’, al-Ṣūfī > Lat. Alromh, Yehūda b. Mošè, Lancea, Apian. Later, al-Rumḥ, al-Qazwīnī, not transcribed by Ideler, who gives Rumḥ al-Rāmiḥ according to al-Tīzīnī > ‘Rumh el-râmih’. Hence Ruma c/ Buttmann, ‘Al-Rumḥ’ p/ Allen, Nit. 02. Rumh al Ramih, Wiki/en
