Description
Abrodictyum dregei (Bosch) Dubuisson & Rouhan, comb. nov., Fig. 2.
Trichomanes dregei Bosch (1858: 372). Type citation: Hab. Cap. bon spei! Drège; Port Natal! Gueinbius. Type:— SOUTH AFRICA. Transkei, Lusikisiki, without date, J.F. Drège s.n. (lectotype S, S-P-18091!, 4 top specimens of the sheet only, here designated; isolectotypes BM, K, K000435631!, K000435632!). Remaining syntype:— SOUTH AFRICA. Port Natal, without date, W. Gueinzius s.n. (S, S-P-18090! 4 bottom specimens of the sheet only).
Note:—The specimen B20 0106572 (B) may be eligible as an isolectotype following Roux (2009), but this specimen has not been retrieved. Roux (2009) also suspected the ‘holotype’ to be present at P, but we did not succeed in finding it, hence we designate here the S specimen as lectotype, in accordance with the note of Schelpe on the sheet (Fig. 2). In addition, the S specimen is better preserved than the K duplicates. The collector of the remaining syntype, cited as “Gueinbius” by van den Bosch, is likely a misspelling for Wilhelm Gueinzius, as correctly written on the herbarium sheet (Fig. 2); Wilhelm Gueinzius is known as a German naturalist who indeed collected in South Africa and precisely in Natal around 1841.
= Trichomanes rigidum Sw. var. lugubre Christ (1901: 849). Type:— DEMOCRATIC REPUBLIC OF CONGO. Kisantu, without date, J.B. Gillet s.n. (holotype BR, BR 0000013468675!).
= Trichomanes rigidum Sw. var. annobonense Brause (Brause & Hieronymus 1915: 378). Type:— EQUATORIAL GUINEA. Annobon Island: Summit of Santa Mina, 650 m, October 1911, G.W.J. Mildbraed 6700 (holotype B, BW 20 0093175!).
= Abrodictyum pseudorigidum Bauret & Dubuisson (Dubuisson et al. 2016: 161), nom. illeg. superfl.. TYPE:— MADAGASCAR. Fianarantsoa: Ambatomboay, RNI d’Andringitra versant E, 40 km au Sud d’Ambalavao, sur les berges d’un affluent de la rivière Sahavatoy, 24 May 1995, F . Rakotondrainibe 2708 (holotype P, P00059914!).
