NOMENCLATURAL COMMENTS
Schelpe (1967) cited two sheets at K as the lectotype of Blechnum bakeri, and only conducted the valid first-step lectotypification of the name (Art. 9.17 of ICN; Turland et al. 2018). Since those two sheets at K are not clearly labeled as being part of a single specimen (Art. 8.3 of ICN; Turland et al. 2018), we here conducted the second-step lectotypification, selecting the sheet with two isolated sterile fronds (annotated E, F). From the same sheet K000424012, the two fertile fronds (annotated G, H) are excluded from the lectotype, as they must be following the first-step lectotypification (Schelpe 1967); we however ascribed the fertile frond H to Cranfillia bakeri Vázquez Ferreira & S.Molino, comb. nov., while frond G was ascribed to Lomaridium biforme (Baker) Gasper & V.A.O.Dittrich.
In the protologue of Blechnum bakeri var. glabrum, Bonaparte (1918) cited C. d’Alleizette 82 (in the Bonaparte’s Herbarium) as the type. This gathering is represented by a single sheet at P, which is the holotype; Rakotondrainibe et al. (2013) erroneously cited P00483199 as an isotype, as this latter sheet in fact belongs to the distinct gathering C. d’Alleizette 82m (i.e. including “m” as a suffix).
