蝦夷方言藻汐草

The facsimile supports ハ in モハウタ. Hirayama lists the historical heading with no modern identification. Kayano momawtacup is a strong semantic alternative for the fifth month, and Batchelor Momauta-chup is assigned to June. Tamura’s shorter mawtacup also belongs to the rose-fruit month-name family. Substituting momawtacup requires an unexplained h/m difference in the source. Neither full form was retrieved in the corpus. Mohawtacup remains a low-confidence reading; the tempting plant-based explanation is conditional.
