Broadnerved humpmoss (''Meesia uliginosa''), is a rare moss of the Western U.S. It occurs all around the northern hemisphere in higher latitudes, and in some places is not as rare as in the Western U.S. == Technical description == Plant autoicous, but many plants with only antheridia or archegonia; plants often fertile. Stems 1–4 cm long, often branched, sans hyaloderm. Basal cells of persistent axillary hairs numerous, strongly reddened. Leaves erect, linear to ligulate-lingulate, never squarrose-recurved, somewhat contorted when dry, smaller at base of stem than larger above, ¾–4½ mm long; margins entire, revolute (i.e., strongly recurved); costa strong, broad (⅓ to ⅔ width of leaf base), ends near leaf apex; apex blunt, obtuse to rounded. Seta very long (1½–10 cm). Capsule pyriform, asymmetrical, curved, up to 4 mm long including neck; neck long, often wrinkled when dry; endostome of 16 segments open on the keel, sometimes with evidence of cilia; outer peristome shorter than the inner. Spores finely papillose.〔 〕〔 〕〔 〕〔 〕〔 〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Meesia uliginosa」の詳細全文を読む スポンサード リンク
