Schizoglossum periglossoides Schlechter (1895a: 20) View in CoL .

Type: — SOUTH AFRICA, Gauteng Province, Pretoria, Mundts farm, alt. 1463 m [ZT, G alt. given as 1600 m.a.s.l.], 5 January 1894, R. Schlechter 4142 (lectotype BOL! [BOL137876], here designated; isolectotypes G! [G00188935], GRA! [ GRA0002396 -0], K! [K000234471], MPU! [MPU019151], NH! [ NH0006706 -0], PRE! [ PRE0347010 About PRE -0; PRE0659062 About PRE -0; PRE0659063 About PRE -0]; Z! [Z-000001755], ZT! [ZT-00013845]) .

From the original description of Schizoglossum periglossoides, Schlechter (1895a) cited two of his own collections (viz. Schlechter 4027 and 4142), both of which have many good sheets, which could be traced. Kupicha (1984) did include Schizoglossum periglossoides in her revision of the genus, but (and we are in agreement with this) attributed it to the genus Stenostelma . She did, however, labelled the Schlechter 4142 at BOL as lectotype and the material at NH and PRE as isolectotypes but never published it. This intended typification was never formally published. In order to avoid confusion we have followed her decision to select the Schlechter 4142 as type material. There is more material of this collection available, which is more widely distributed and represent the taxon as well as Schlechter 4027. It also overcomes the confusion of some sheets with the number 4027 being wrongly numbered 4029 in some herbaria. Duplicates of syntype Schlechter 4142, collected in Mpumalanga Province, marshy areas near Klein Olipfants (sic.) River, alt. 1615 m on 21 December 1893 can be found at B!, G!, GRA!, MEL!, NH!, PRE!. Z!). The B and Z are orthographically misinterpreted as Schlechter 4029.
