Fucus digitatus var. pellucidus Clemente ex Colmeiro (1867: 213)

= Laminaria reniformis J.V. Lamouroux (1813: 22) [≡ Phyllaria reniformis (J.V. Lamouroux) Rostafinsky in Bornet (1892: 250)].

= Laminaria brevipes C. Agardh (1821: 116) . [≡ Phyllariopsis brevipes (C. Agardh) E.C. Henry & G.R. South (1987: 13) subsp. brevipes J.L. Pérez-Cirera et al. (1991: 4) ].

Ind. loc.: “Clem. loc. cit. Málaga (Clem.)” ( Colmeiro 1867: 213). “Copiose ad Málaga.” [Transcript of the XXVII card [no number] of “ Flora Boetica ” unpublished, Clemente ( Bellón 1942: 6)].

Neotype (designated here):– SPAIN. “ Fucus digitatus . Turn. Vs./ Comun [handwritten by Clemente]” ( GDA 45385 !), see Fig. 1 [photo avaible in “ Tipos nomenclaturales de algas ” at the Herbarium of the University of Granada website: http://herbarium.ugr.es/pages/imagenes/tipos-nomenclaturales/algas/_img/gda45385/!].

The specimens have been reviewed by Bellón in 1938 as Phyllaria reniformis , a name now considered to be Phyllariopsis brevipes subsp. brevipes , according to the revision labels with the specimens. This identification corresponds to the review of the algae collection of Clemente by Bellón for the publication of his work “ Las algas de la ‘Flora Boetica’ inédita, de Clemente ”. In this work ( Bellón 1942: 39, 40) confirms the revision of this and other sheets of the HSMS, as well as the identification of Colmeiro (1867: 213), who considered F. digitatus var. pellucidus Clemente as a synonym for Hafgygia digitata var. membranacea Kützing (1843: 346) [which is now a synonym of Laminaria digitata (Hudson) J.V. Lamouroux (1813: 42) ].

When the collection was reviewed by Cremades (1990), that author failed to find any specimen belonging to this taxon in the herbarium of the Royal Botanic Garden of Madrid (MA–Algae), and following the indications of Bellón (1940) about the existence of three specimens which Clemente has identified as F. digitatus included in the HSMS, checked them and selected a neotype, without publishing it. The three specimens all lack varietal epithets. However, it is known that Clemente did not describe any other variety of F. digitatus . Thus Cremades selected the fertile specimen (with a large sorus at its base) as the neotype because it closely fit the protologue (Cremades, 1990). The review label of the Royal Botanic Garden of Madrid, handwritten by Cremades in 1990, reads “ Phyllariopsis brevipes (C. Agardh) Henry & South / NEOTYPUS of Fucus digitatus var. pellucidus Clemente / ex Colmeiro 1867: 213 ”.
