= Notholaena flavens (Sw.) T. Moore, Index Fil. (T. Moore) 2: LXX. 1857 [April 1857] [as “ Nothoclaena ”].
= Notholaena flavens (Sw.) Raimondi, Elem. Bot. (Raimondi) View in CoL 2: 59. 1857 [as “ Nothoclaena flava ”], probable isonym, as discussed by Molinari-Novoa (2021).

Syntypes: — PERU: Poeppig & Mathews 755, Mclean s.n., and Lechler 1830; ECUADOR: Spruce 5632, Seemann s.n. ( K, only Seemann s.n. seen: http://specimens.kew.org/herbarium/ K000633284 ) .
According to the Nomenclature Code ( Turland et al. 2018, Art. 11.4), the epithet flavens Sw. , at species rank, has priority over flava , at varietal rank.
Full synonymy, including the later names Acrostichum tereticaulon Desv. and Notholaena chrysophylla Klotzsch , was given by Tryon & Weatherby (1956).
Molinari-Novoa (2021) discussed this species and surmised that the type, a collection by Née, was likely from Panama or Colombia. This species is accorded a range from Colombia, Ecuador, Peru, Bolivia, northwestern Argentina, and southern Brazil ( Tryon & Weatherby 1956, Mickel & Smith 2004), but nearly all recent collections are from Peru southward. Tryon did cite Colombia in the range (Mutis 2102, 2104, US) and Ecuador (Sodiro s.n., P; Seemann s.n., K). The determinations of the Mutis specimens, judging from images, are dubious, in part because the specimens are poor; however, they do appear to be Argyrochosma , possibly A. nivea s.s, known from Ecuador, or perhaps some other species of Argyrochosma , although we know of no other argyrochosmas from Colombia or Panama ( Moran 1995). Née is known to have collected in Panama-Colombia but we doubt this locality, because this fairly distinctive species has never been collected there since. Based on more recent collections, a more tenable hypothesis is that the specimen came from southern Ecuador or Peru, where Née is also known to have collected. Née was good friends with Cavanilles and sent most of his specimens to Cavanilles in Madrid, who in turn sent a frond from the Née collection to Swartz. We surmise that the specimen in S somehow was mislabeled as to locality, a common occurrence with early collectors, including Née.
