AF3987E01822FFAE90CFFEFC5F5ED012.taxon	discussion	REMARKS This name was lectotypified by Griffiths et al. (2022) based on the specimen Hens 69 from L with an isolectotype at BR. Clarke (1894: 568) came up with the new name Cyperus mapanioides but without a proper description (nomen nudum). The name was later validated by Clarke himself (1901 - 1902: 340). He merely cited two collections: “ Afr. occ.: Congo, Hens 7, 69 ”. Frans Hens (1856 - 1928) was a painter, who was the first Belgian to collect plant samples in Congo (in 1887 and 1888). His name was not mentioned by Stafleu & Cowan (1976 - 1988), from which it can be deduced that he was a rather unimportant collector. However, several hundred Hens specimens are kept in BR, including both specimens cited by Clarke. Duplicates of both are preserved at K and L, with Hens 7 moreover also located at BM. The Hens 69 gathering (both the BR, K and L accessions) shows very young specimens with an inflorescence that is hardly exserted from the upper leaf sheath. Hens 7 from BR (the source herbarium), in turn, shows a complete specimen (in the K collection the roots are missing) with a mature inflorescence. The collection was annotated by Clarke on 11 December 1894. It is clear that this latter collection, Hens 7, which is also kept in several large public herbaria, would have served better for a possible lectotypification. This collection was already (ineffectively) referred to as such in our monographic study (Mesterházy et al. 2022).	en	Verloove, Filip, Mesterházy, Attila (2025): Lectotypification of names in the genus Cyperus s. l.

AF3987E01822FFAE9097FA7F5F24D2D6.taxon	discussion	REMARKS This name was already lectotypified by Larridon et al. (2014) – i. e. prior to the publication of Mesterházy et al. (2022) and was therefore overlooked by us – based on the collection H. Scaetta 58 M from BR with an isolectotype at K. Out of the five syntypes cited by Chermezon (1934) in the protologue only the two Scaetta gatherings (58 M and 2418) seem to be extant. Both were mentioned as possible types in Mesterházy et al. (2022). The designation by Larridon et al. (2014) is therefore plausible.	en	Verloove, Filip, Mesterházy, Attila (2025): Lectotypification of names in the genus Cyperus s. l.

AF3987E01824FFA89270FEBC5BF8D0F3.taxon	discussion	REMARKS The name Cyperus baikiei was mentioned by Clarke (1894: 550) in the Conspectus Florae Africae, indicating its origin (“ Afr. occ. - bor.: Sierra Leone, Scott Elliott [sic] 5676. Afr. occ.: Bas Niger ”) but without a description or diagnosis (nomen nudum). Kükenthal (1925: 325), who validated the name, provided the following collection details: “ Trop. Westafrika: Senegambien, Ufer des Bani (A. Chevalier no. 1086!); Sierra Leone, zwischen Bumban und Port Lokko (Scott-Elliot no. 5676!); Niger (Baikie!) ”. The Chevalier collection, that should be in P (Stafleu & Cowan 1976 - 1988), could not be traced. The latter two gatherings are preserved at K. The Scott-Elliot gathering, to which was already referred by Clarke, comprises a complete but young individual, with the inflorescence barely exserted from the upper leaves (barcode K 000321313). The third syntype, the Baikie collection that is preserved at K, bears three complete specimens, two of which with a mature inflorescence (barcode K 000321312). A duplicate of the Baikie collection is preserved at B (B 10 0166379); it was annotated by G. Kükenthal in 1923. The latter Kew specimen is designated as the lectotype of the name Cyperus baikiei.	en	Verloove, Filip, Mesterházy, Attila (2025): Lectotypification of names in the genus Cyperus s. l.

AF3987E01824FFA8925BF9D85F76D44C.taxon	discussion	REMARKS Clarke (1883: 289) cited two collections in his protologue of the species: “ Madagascar centralis. Baron nn. 484, 695 ”. Out of these two syntypes only Baron 695 is found in various online herbaria (e. g. K, P, and BM). The specimen preserved at P (P 00450551) only comprises two inflorescences and a leaf. The specimens preserved at Kew (K 000362679) and BM (BM 000922483), in contrast, represent complete specimens bearing roots, stems, leaves and an inflorescence and could both serve for lectotypification purposes. The Kew specimen is the better specimen and was verified by Clarke himself; it is here designated as lectotype for this species.	en	Verloove, Filip, Mesterházy, Attila (2025): Lectotypification of names in the genus Cyperus s. l.

AF3987E01824FFA89777FE7C59A2D2D6.taxon	discussion	REMARKS Ridley (1884: 127) cited three syntypes in the protologue of this species, all from the Welwitsch herbarium: Angola, Pungo Andongo, in paludosis prope Lombe […], Mar. 1857, n ° 6913; Mutollo Sobata de Guinga […], Jan. 1857, n ° 6914 and Huilla, in pascuis editis ad Morro de Lopollo versus Empalanca, […], Apr. 1860, n ° 6871. A fourth collection, Welwitsch 7154, was also considered to be a syntype by Hoenselaar et al. (2010). The label bears the same details as Welwitsch 6914 (Mutollo, Jan. 1857). However, because this collection number was not mentioned in the protologue, it is not a syntype and therefore cannot be selected as a lectotype. The three Welwitsch collections mentioned in the protologue all are preserved in LISU and BM, where Welwitsch’s Angola specimens are located (respectively his first and second set; see Stafleu & Cowan 1976 - 1988), with duplicates deposited in many other herbaria. After a legal dispute, the main set was assigned to the Lisbon herbarium (LISU), the secondbest set to the Natural History Museum in London (BM) (Albuquerque et al. 2020). All three collection numbers in LISU – with Welwitsch 6914 even being represented by two separate sheets – are eligible for lectotypification purposes. All these collections were also seen and cited by Kükenthal (1935 - 1936) in his world monograph. Welwitsch 6913 (barcode LISU 224752) is represented by six entire specimens, nearly all of them quite mature and with the majority of the glumes already fallen. As a result, the verification of any floral characteristics (e. g. number, color and size of the stamens) may no longer be possible. Welwitsch 6871 (barcode LISU 224756) only shows a single entire plant. It was studied by one of us (AM) at LISU and it belongs to Cyperus capillifolius A. Rich. [syn.: Pycreus capillifolius (A. Rich.) C. B. Clarke]. Welwitsch 6914 is left; it is represented by two almost identical sheets (LISU 224753 and LISU 224754). Both sheets contain several specimens, nine and six respectively, collected at both the flowering and fruiting stage. The first sheet includes both young and mature specimens; it is therefore best suited for lectotypification.	en	Verloove, Filip, Mesterházy, Attila (2025): Lectotypification of names in the genus Cyperus s. l.

AF3987E01828FFA4923CFF135965D073.taxon	discussion	REMARKS In the protologue of this species Chermezon (1931) cited two gathering numbers, Tisserant 332 collected in Bambari in December 1920 and Tisserant 332 bis collected in Région de la Waka in March 1928. These collection numbers are represented by five sheets in P (P 00569082, P 00569083, P 00569084, P 00569085 and P 00569086). Duplicates of Tisserant 332 and 332 bis are moreover located in BR (BR 0000005572489 and BR 0000005571833, respectively). All collections from Bambari that were collected in December 1920 (i. e. Tisserant 332), are better developed than those of March 1928; the latter show younger specimens with poorly developed inflorescences. Tisserant 332 therefore is preferred for typification purposes. According to the Paris herbarium catalogue it is represented by two sheets: P 00569082 and P 00569083. However, the latter sheet – although numbered as ‘ 332 ’ – was made in December 1928 and is thus in fact referable to Tisserant 332 bis. The confusing numbering has also led to dates and collection numbers being mixed up in BR, until corrections were made by P. Bamps. Nonetheless, the Tisserant 332 collection in BR (BR 0000005572489) bears a mixture of confusing elements: it was allegedly collected in Bambari, indeed shows mature specimens with well-developed inflorescences but is dated (or was merely annotated?) 30 December 1928. No further dates are discernible on this specimen. In short, only the P collectionP 00569082 unequivocally dates from December 1920; it is here designated as the lectotype for this name. Due to the confusion surrounding the numbering of the other Tisserant collections, no isolectotypes are selected.	en	Verloove, Filip, Mesterházy, Attila (2025): Lectotypification of names in the genus Cyperus s. l.

AF3987E01828FFA49384FA585FCED1B2.taxon	discussion	REMARKS Hochstetter coined this name (date unknown), but apparently only on a herbarium label and without a formal description, as was often the case with Hochstetter names (it supposedly was a nomen nudum). This can at least be deduced from Boeckeler (1868: 580) who added “ in sched. ” (in schedula, i. e. on a label) after the name Cyperus reduncus and validated it. In his protologue of this species, Boeckeler referred to “ Abyssinia ” and “ Schimper ”, without further indications. The herbarium of G. W. Schimper was preserved in B (partly destroyed) and in P, with numerous duplicates in other herbaria (Stafleu & Cowan 1976 - 1988). However, neither B nor P actually contain specimens of C. reduncus that were collected by Schimper in Abyssinia. Hoenselaar's assumption (Hoenselaar et al. 2010) that the (holo-) type is located in B is therefore incorrect (it can be assumed that, if it ever existed, the collection was destroyed during World War II). In the C. F. Hochstetter herbarium, now incorporated at TUB (Stafleu & Cowan 1976 - 1988), a specimen is preserved that bears a label: “ In Abyssinia legit et paucula. Specimina misit W. Schimper ”; it is dated “ 19 Sept [18] 38 ”. The collection represents a complete plant showing all diagnostic features typical for the species. It corresponds with the information provided in the protologue by Boeckeler l. c. and was collected well before Boeckeler l. c. validated C. reduncus as a new species and thus can be considered as original material. This collection is here designated as the lectotype for this name. Interestingly, at S there is an undated historical collection, originating from the area where the type material also comes from (“ in uliginosis prope Gapdiam ”) (S 13 - 17060). It may be original material, even if no collector is listed and no date is mentioned. After the name Cyperus reduncus Hochst. follows an extensive description of the species so that it could be assumed that it concerns Hochstetter's original collection, based on a Schimper specimen (in which case the name would have been validly published by Hochstetter and a validation by Boeckeler was superfluous). However, the handwriting does not correspond to that of Hochstetter (compared with examples of his handwriting presented by Steinberg 1973). Moreover, Hochstetter's herbarium is located in TUB, as far as known without duplicates in S. Considering the doubt that surrounds this collection, it is better not to take it into account for typification purposes.	en	Verloove, Filip, Mesterházy, Attila (2025): Lectotypification of names in the genus Cyperus s. l.

AF3987E01828FFA490BDFB1F599CD2D1.taxon	discussion	REMARKS Boeckeler (1870: 286) based his description of Cyperus tenuiculmis primarily on Wallich 3321. In addition, he referred to gatherings from Sierra Leone (Afzelius s. n.), Nupe [Nigeria] (Barter 1573), East India (Hook. & Thoms. s. n.), Batavia [Indonesia] (Jungh. s. n.), Ceylona [Sri Lanka] (Thwaites 807) and Luzon [Philippines] (Haenke s. n.; Meyen s. n.). The gathering Wallich 3321 is preserved in several herbaria, several of which are accessible online (e. g. BR, G, K, and P). The Paris specimen was annotated as isotype by Kern while revising Cyperus for Flora Malesiana. P. Van der Veken did the same for the specimen held in BR. The Wallich herbarium is incorporated in K (initially as K-W) with further material in numerous other herbaria. His type specimens, however, are mainly at K (Stafleu & Cowan 1976 - 1988). The Wallich 3321 specimen (K 000592514) is here designated as lectotype for C. tenuiculmis.	en	Verloove, Filip, Mesterházy, Attila (2025): Lectotypification of names in the genus Cyperus s. l.

Both collections are kept in P, where the Trochain herbarium and types are located (Stafleu & Cowan 1976 - 1988). Duplicates are deposited in BR. Trochain 3545 represents a complete specimen with roots, flowers and fruits, whereas Trochain 3538 only bears three stems (no roots), two of them in flower / fruit, a third with a young inflorescence that hardly emerges from the upper leaf sheath. Both collections were seen by J. Raynal in June 1970 who included this species in P. flavescens (L.) P. Beauv. ex Reich. Trochain 3545 is the most representative out of the two syntypes and it was already annotated (informally) as lectotype for this name, possibly by J. Raynal.
