Revision of part of the Middle Jurassic flora of Sardinia, the Krasser collection, stored in Prague (Lovisato B collection), containing 23 fossil taxa of horsetails, ferns, cycadophytes, ginkgophytes and conifers. The conifers are most diverse, followed by cycadophytes and ferns. The composition of this assemblage differs notably from the Lovisato collection stored in Cagliari, suggesting that it might derive from a different stratigraphic level and/or palaeoenvironment. The palaeodiversity of the Middle Jurassic flora of Sardinia increases to 46 fossil taxa with this revision. Cycadolepis sp. Nilssonia sp., Nilssonia sp. cf. N. orientalis, Pagiophyllum sp. and Agathoxylon sp. are described for the first time from the Middle Jurassic of Sardinia. © 2016, National Museum Prague. All rights reserved.
