Description of change

Arthrobotrya was a small genus in PPG I that used to be treated as a synonym of Teratophyllum. Recent study showed that both the molecular phylogeny and morphological characteristics evidences support treating Arthrobotrya as a synonym for Teratophyllum.

Reason for change

Arthrobotrya was recognized by PPG I but has recently been shown to be nested in Teratophyllum. The key morphological characteristics distinguishing Arthrobotrya from Teratophyllum are also not clear. Furthermore, Teratophyllum and Arthrobotrya share similar habits and overlapping distribution areas.

Arachniodes macrostegia and A. ochropteroides which are closely related to Olfersia in Lu et al. (2019) is absent in this article. So now the genus Arachniodes s.s. is not still defined.

Hi Dr. Hori, thanks for bringing this up. We treated/included Arachniodes macrostegia and A. ochropteroides neither in Lu et al. (2019) nor in Zuo et al. (2024) because Dr. Robbin Moran and colleagues have been working on them. Arachniodes s.l. was found as poly-/paraphyletic by Moran & Labiak (2015): PHYLOGENY OF THE POLYBOTRYOID FERN CLADE (DRYOPTERIDACEAE). Int. J. Plant Sci. 176(9): 880–891.

If there are some conflicts of interests, I have a concern there are no comments about Arachniodes macrostegia and A. ochropteroides in Zuo et al . (2024). According to the phylogeny of Lu et al. (2019), It needs to define two different genus for these two species to define the genus Arachniodes s.s.
