The facsimile has initial ヲ. Batchelor Oman-no-po means distant/far and Hirayama quotes this comparison under オマンノボ. omannopo follows the recorded initial without adding h. Spaced oman no po records a possible division; its full historical grammar remains unsettled. The competing homannopo comes from the companion ホマンノボ, while homanno itself means faintly or vaguely in modern dictionaries and the two retrieved contexts. Neither complete candidate has a corpus match. Hirayama and the second transcription of Batchelor provide cross-checks of the cited reading, without establishing independent historical uses.
