Comment:Chapman attributes this name to "(Hook. & Grev.) Bosch... Verslagen en Mededeelingen der Koninklijke Akademie van Wetenschappen 11 (1861) 318" [i.e. R.B. van den Bosch, Verslagen Meded. Afd. Natuurk. Kon. Akad. Wetensch. 11: 318 (1861)]. While van den Bosch lists Hymenophyllum marginatum Hook. & Grev. under his new genus Pachyloma he does not definitely associate the genus name and specific epithet as required under ICN Art. 35.2 (Shenzhen Code, 2018).
