EA53227F230A0B7F6209F9D5FA7AFA9F.taxon	discussion	Notes. – A single specimen of original material is extant in LINN-HS [LINN-HS nº 1622.51]. This specimen bears a label in Thouin’s handwriting including the number “ 31 ” to which Linnaeus f. added in his hand “ australe ny ” (“ ny ” indicating ‘ new’). The LINN-HS specimen was cited as holotype by PICHI-SERMOLLI (1962) and this use is here treated as an error to be corrected to lectotype (TURLAND et al., 2018: Art. 9.10). Duplicates of this original material have been located in MPU [MPU 1071909] and SBT [SBT nº 1.2.1.28].

This specimen bears a label in Thouin’s hand to which Linnaeus f. has added the words “ punctatum ny ” (Fig. 2, 4). This specimen bears the number “ 28 ”. Two collections representing duplicates of the original material have been located in MPU [MPU 1054971, MPU 1054973] and are considered as isolectotypes. A third duplicate of this original material has been located in P [P 01427005]. This specimen is the only known duplicate originating from the herbarium of Dr. Baron J. - A. Barbier (1767 – 1846), bequeathed to the MNHN and incorporated within the collection in 1847. The identity of the lectotype material corresponds with the current usage of the name.

EA53227F230F0B7A62F0F9EEFB00FB3F.taxon	discussion	Notes. – A single specimen of original material is extant in LINN-HS [LINN-HS nº 1629.23]. This specimen bears a label in Thouin’s hand to which Linnaeus f. added the epithet “ vivipara ”. This specimen bears the number “ 26 ” and is here designated as lectotype. Three duplicates of original material have been located in MPU [MPU 1036711] and in G [G 00341868, G 00341869]. The G duplicates originate from the herbarium of Augustin-Pyramus de Candolle (1778 – 1841). The combination of Acrostichum viviparum in the genus Asplenium L. proposed by PRESL (1836) is illegitimate as it is a later homonym of Asplenium viviparum published by BLUME (1828). The correct name is A. daucifolium Lam. published in 1786. LAMARCK (1786: 310) cited in the protologue: “ M. Commerson a trouvé cette plante à l’Isle de France. (v. s. in h. D. Thouin) ”. The original material has been located in Thouin’s herbarium in MPU. It bears in Lamarck’s hand: “ daucifolium lam. dict. ” (Fig. 5). The type was mistakenly believed to be in P by MORTON (1963). A collection in P-LA [P 00564950] cited by TARDIEU-BLOT (2002) as a possible isotype is not considered as original material as it was determined as “ Darea ” by Lamarck with no direct reference to A. daucifolium except the locality “ isle de France ”.	en	Callmander, Martin W., Mazumdar, Jaideep, Jarvis, Charles E.

EA53227F230F0B756140FB55FF5AFBFF.taxon	discussion	Notes. – The protologue of Adiantum furcatum included references to PLUKENET (1700: 83, tab. 350, fig. 4) and to two specimens as “ Thunberg. Thouin ” with the mention “ Habitat in Cape. Bonae Spei & Insula Helenae ”. Two specimens of original material are extant in LINN-HS: a specimen collected by Carl Peter Thunberg (1743 – 1828) in the Cape region [LINN-HS nº 1629.16] with duplicates in SBT [SBT 10616] and UPS [UPS-THUNB nº 24774], and a specimen from Réunion originating from Thouin’s shipment in 1780 (see above) [LINN-HS nº 1629.15]. SWARTZ (1801, 1806) excluded the reference to “ Filicula corniculata Insulae Sanctae Helenae ” of PLUKENET (1700) which refers to a species of Elaphoglossum Schott ex J. Sm., E. bifurcatum (Jacq.) Sw., a fern endemic to St. Helena. CHRIST’s (1899) transfer of Adiantum furcatum to Elaphoglossum (as E. furcatum (L. f.) Christ) is a nom. illeg. currently treated as a synonym of E. bifurcatum (Jacq.) Sw. (ROUX, 2009; VASCO et al., 2009). The two specimens of original material extant in LINN-HS where Linnaeus f. added “ Adianthum furcatum ” are identifiable as a species of the genus Asplenium L. The combination of Adiantum furcatum in the genus Asplenium would be illegitimate, as it is preoccupied by Asplenium furcatum Thunb. (= A. aethiopicum (Burm. f.) Bech.). Linnaeus f. ’ s name should be treated as a synonym of Asplenium rutifolium (TARDIEU-BLOT, 1958), the first available name in the genus. Its basionym, Caenopteris rutifolium, was described by Peter Jonas Bergius (1730 – 1790) based on a Thunberg collection in SBT [SBT 10616], a duplicate of original material (isosyntype) of Adiantum furcatum. The Commerson s. n. collection [LINN-HS nº 1629.15] (bearing the number “ 40 ” corresponding to the younger Linnaeus manuscript list sent to Thouin) is here designated as lectotype. It is chosen over the Thunberg collection as Linnaeus f. added to the label “ Adianthum furcatum ny ”.
