New molecular and morphological evidences favor a combination of Blechnum bakeri C. Chr. in Cranfillia Gasper & V. A. O. Dittrich (Blechnaceae, Polypodiopsida), thus extending the distribution of Cranfillia to Madagascar and East Africa Author Bauret, Lucie Author Vázquez, Rubén Author Molino, Sonia Author Gaudeul, Myriam Author Rakotondrainibe, France Author Gasper, André Luís de Author Rouhan, Germinal text Adansonia 2020 3 2020-11-30 42 18 279 289 journal article 8796 10.5252/adansonia2020v42a18 bcde5d36-2c05-46bf-849d-1715c64aea39 1639-4798 4448027 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 ] .................................
