The IAU catalogue's account
Applied in recent times from an abbreviation of its name for the Arabic Almagest period ra's alasad (al-shamali), "(the Northern [Part] of) the Lion's Head." As originally applied, μ Leo was "Rasalasad Borealis" abbreviated in the first Western astronomical source as "Rasalas. Bor.," for lack of space in the line), and ε Leo was "Rasalasad Australis" (after the Arabic).

Layer of tradition and ancient-layer signal are not the dictionary authors' judgement but a keyword reading of the entry's wording. “No simple cue found” means exactly that — the parser found none — not that the name is late.
