Hoa Binh Prov.: Ke Son, December 1926, Colani 3409 (lectotype, UC- 421511!, designated here; isolectotype, US- 01580326!).	en	Dong, Shi-Yong (2022): The new combination Tectaria colaniae and notes on the synonymy and distribution of Tectaria wigmanii (Tectariaceae).

03F18787FFABFF91FF12BC2E2F8BF8BB.taxon	discussion	When describing Ctenitopsis colaniae, Tardieu-Blot and Christensen (1938) cited Colani 3409 as the sole collection of their new species and noted “ type in Herb. C. Chr. et herb. Mus. Paris ”. I failed to locate the type specimens mentioned by the authors in BM or P, but found one duplicate (syntype) in UC and one in US (herbarium codes follow Thiers 2022). The two syntypes agree well with the original description by the authors and the one in UC is designated here as the lectotype of this species. Tectaria colaniae appears to be a morphologically distinct species, though it is hitherto represented only by its type specimens. It is characterised by the free veins, subdimorphic sterile-fertile fronds, 1 - pinnate-pinnatifid fronds each composed of two pairs of free pinnae and a pinnatifid apical lamina, and the shape of the basal pinna, which has its basal basiscopic segment slightly or obviously reduced (Fig. 1). By the combination of these characters, T. colaniae is morphologically distinct and readily distinguished from other species of Tectaria. In the shape and size, the fronds of T. colaniae are quite similar to some sterile fronds occurring in T. nayarii Mazumdar (2014: 297). However, Tectaria nayarii (formerly known as Heterogonium pinnatum [Copeland 1906: 146] Holttum [1949: 163]) differs in having anastomosing veins and strongly contracted fertile fronds, and is distributed from Peninsular Thailand to Malesia and the Solomon Islands (Holttum 1991; Chen & al. 2017). Though not yet sampled in any phylogenetic analyses, T. colaniae is presumed to be closely related to T. sagenioides (Mettenius 1858: 397) Christenhusz (2010: 58), as both species share the same pattern of venation and frond division, and have similarly shaped basal pinnae. Notably, T. colaniae differs from T. sagenioides in the deltoid (versus oblong and much longer) fronds and much fewer (2 – 3 versus generally 10 – 15) pairs of free pinnae.	en	Dong, Shi-Yong (2022): The new combination Tectaria colaniae and notes on the synonymy and distribution of Tectaria wigmanii (Tectariaceae).

Kaudern 18 (lectotype, designated here, S-P- 10859!; isolectotype, BM- 001048664!).	en	Dong, Shi-Yong (2022): The new combination Tectaria colaniae and notes on the synonymy and distribution of Tectaria wigmanii (Tectariaceae). Phytotaxa 566 (2): 245-248, DOI: 10.11646/phytotaxa.566.2.10, URL: http://dx.doi.org/10.11646/phytotaxa.566.2.10
03F18787FFA9FF93FF12B8D32F5CFC7F.taxon	discussion	When publishing Dryopteris sagenioides var. gurupahensis, Christensen (1922: 95) cited two numbers of Kaudern’s collections, 17 and 18, as the type; these two are syntypes according to Art. 9.6 of the ICN (Turland & al. 2018). The syntype Kaudern 18 kept in S (barcode S-P- 10859) is here designated as the lectotype. As the type of this taxon agrees with the type of T. wigmanii (then named Heterogonium wigmanii), Holttum (1975) treated them as representatives of a single species. As mentioned by Holttum (1975), T. wigmanii is morphologically very similar to T. sagenioides but differs by the larger size of fronds, which are up to 50 – 75 (versus 30 – 40) cm long. The two species are thought to have different distribution, namely, T. wigmanii is confined to Sulawesi and Maluku, Indonesia, whereas T. sagenioides occurs in Philippines, West Malesia, and northwards to Indochina and Hainan Island (Holttum 1975, 1991). So Heterogonium gurupahense recorded in Thailand (Tagawa & Iwatsuki 1988) and in Vietnam (Phan 2010) should be corrected to be T. sagenioides. It seems to me that there is no significant difference between T. wigmanii and T. sagenioides besides the larger frond size and the clear dimorphism (fertile fronds obviously contracted) in T. wigmanii. Further studies, especially chromosome counting and molecular phylogenetic analyses, are needed to confirm the taxonomic identity of T. wigmanii.	en	Dong, Shi-Yong (2022): The new combination Tectaria colaniae and notes on the synonymy and distribution of Tectaria wigmanii (Tectariaceae).
