Early Permian silicified floras from the Perdasdefogu Basin (SE Sardinia): comparison and bio-chronostratigraphic correlation with the floras of the Autun Basin (Massif central, France) Author Galtier, Jean Author Ronchi, Ausonio Author Broutin, Jean text Geodiversitas 2011 2011-03-31 33 1 43 69 http://dx.doi.org/10.5252/g2011n1a4 journal article 7722 10.5252/g2011n1a4 bf362508-4a23-4fb9-ad93-d75fe2d5cd7d 1638-9395 4596948 Anachoropteris pulchra Corda, 1845 ( Fig. 6H, I ) A few fragments of rachises of this fern have been found; one ( Fig. 6H ) shows the characteristic abaxially enrolled xylem strand, a feature more hardly visible in another specimen ( Fig. 6I ). The latter is a larger rachis with a still more inrolled xylem strand. Both are conform to the species Anachoropteris pulchra Corda from Radnice, also recognized at Grand-Croix and Autun ( Corsin 1937 ). Marattialean tree ferns: fragments of the different parts of the plant are present in nearly 90% of the specimens including Psaronius trunks with aerial roots, Stewartiopteris petioles and rachises, Pecopteris and Scolecopteris pinnules
