was first described in 1927 by V.F. Brotherus, based on materials from Hawaii. It has, so far been, treated as a separate species. A detailed analysis of the original material housed in the New York Botanical Garden Herbarium (NY01256708) found the specimen to be characterised by a lack of metallic lustre; concave, asymmetrical, lanceolate to lanceolate-ovate leaves, shrunken in their dry condition; a straight, not denticulate, acute to apiculate apex; elongate-hexagonal cells in irregular transverse rows, 101-131 × 15-21 µm at mid-leaf; very lax areolation, with decurrencies composed of three rows of cells. These characteristics indicate that this species is identical to the original material of (e.g. H-SOL 1563 011; PC0132572). Hence, we propose that should be recognised as a new synonym of . In addition, a review of syntypes found one (H-SOL 1563 011) to have the same date of collection as the protologue, and to possess a quite abundant gametophyte turf with well-preserved sporophytes, indicating it to be fertile. Considering the above, we propose that specimen H-SOL 1563 011 be designated the lectotype of .
1927年，V.F. 布罗特鲁斯根据来自夏威夷的材料首次对其进行了描述。到目前为止，它一直被视为一个独立的物种。对存放在纽约植物园标本馆（NY01256708）的原始材料进行的详细分析发现，该标本的特征是缺乏金属光泽；叶片呈凹形、不对称，披针形至披针形卵形，干燥时收缩；顶端直，无细齿，锐尖至具小尖；叶中部的细胞呈细长六边形，不规则横向排列，大小为101 - 131×15 - 21微米；细胞间隙非常疏松，由三排细胞组成下延部分。这些特征表明该物种与（如H - SOL 1563 011；PC0132572）的原始材料相同。因此，我们提议应将其视为的一个新异名。此外，对的合模式标本进行审查时发现，其中一个（H - SOL 1563 011）的采集日期与原始描述相同，并且具有相当丰富的配子体草皮和保存完好的孢子体，表明它是可育的。考虑到上述情况，我们提议将标本H - SOL 1563 011指定为的选型模式。
