IDENTIFICATION KEY TO THE SPECIES CLOSELY RELATED TO CRANFILLIA BAKERI (C.CHR.) VÁZQUEZ FERREIRA & S.MOLINO, COMB. NOV.

1. Sterile laminae with fully adnate pinnae in distal half, and with partially free pinnae in proximal half (sometimes only in 1/3 proximal of its length) [Lord Howe Island] ...... C. fullagari (F. Muell.) Gasper & V.A.O.Dittrich

— Sterile laminae with fully adnate pinnae all along the length, except for the first 1-2 (-3) most basal pinnae pairs, which are partially free at least basiscopically ............................................................................................... 2

2. Scales from nigrescent to light brown; perine ornamentation with curly thin muri, which do not give the spore a polyhedral shape [N. Zealand] ............................................... C. nigra (Colenso) Gasper & V.A.O.Dittrich

— Scales notably atropurpureous; perine ornamentation with straight thick muri which give the spore a polyhedral shape ........................................................................................................................................................... 3

3. Trichomes remarkably opaque and atropurpureous, from dense to scattered but always present at least on the abaxial surfaces [ New Caledonia, Fiji, Vanuatu] ........................... C. opaca (Mett.) Gasper & V.A.O.Dittrich

— Trichomes when present, light brown (never atropurpureous); often completely glabrous individuals ......... 4

4. Sterile blade triangular-ovate; basal segments lanceolate to linear-elliptic; apical segments obtuse, sometimes slightly acute [ Brazil] ................................................................ C. mucronata (Fée) V.A.O.Dittrich & Gasper

— Sterile blade lanceolate-ovate; basal segments semicircular, sometimes ovate; apical segments acute to acuminate [East Africa, Madagascar] ................................. C. bakeri (C.Chr.) Vázquez Ferreira & S.Molino , comb. nov.
