“…Pseudolycopodiella can be distinguished from other South American members of the subfamily Lycopodielloideae (i.e., Lycopodiella Holub, Palhinhaea Vascon. & Franco) by the following character states: 1) sporophytes with prostrate, rooting, indeterminate, isophyllous to strongly anisophyllous, horizontally branching shoots and dorsally arising, erect, simple strobiliferous branches with leaves that conform with those of the prostrate shoots or leaves that are strongly reduced and distant; 2) sporophylls arranged in alternating whorls of 3-5, rarely decussate, forming 4-10 (-12) longitudinal ranks, free, not enclosing the sporangia at maturity, without veinal mucilage canals; 3) sporangia isovalvate, reniform, widely attached to the sporophyll stalk: sporangium epidermis cells with incompletely lignified or with incomplete semiannular thickenings (Øllgaard 2014, Øllgaard andWindisch 2016). Bonnetia (Bonnetiaceae), and Aratitiyopea (Xyridaceae) (Berry et al 1995, Neill 2005, 2007, Wurdack 2017; several new taxa have also been discovered (Gradstein et al 2019, Mashburn et al 2020, Pérez et al 2020, 2021.…”
