Boucheron-Dubuisson, Elodie, Zhao, Yanan, Rouhan, Germinal, Ebihara, Atsushi, Iwatsuki, Kunio, Darnaedi, Dedy & Dubuisson, Jean-Yves, 2024, The first record of Trichomanes s. s. (Hymenophyllaceae) in Asia and establishment of the new subgenus Asiatrichomanes, Phytotaxa 633 (3), pp. 215-229 : 224

Trichomanes L. subgenus Asiatrichomanes Ebihara & Dubuisson , subg. nov.

Terrestrial plants morphologically and genetically close to Trichomanes subgenus Davalliopsis (Bosch) Ebihara & K.Iwats. , but with one-cell-thick lamina bearing glandular-like hairs on the adaxial side and sori bearing a crown of hairs identical to those on the laminae, vs. three-cell-thick, hairless lamina and hairless sori for Davalliopsis .

Type:— Trichomanes superbum Backh.

The description and distribution of the subgenus are those of its single species, as developed here-after. The etymology refers to the tropical Asian distribution, unique within Trichomanes .

Except in Flora Malesiana ( Iwatsuki & Ebihara 2023), the previous descriptions of the species and its synonyms are generally partial and more like diagnoses. We provide here a new, complete morphological description in order to clarify certain characters, including meristic data, and that also complements the description of Flora Malesiana.
