AbstractThe root anatomy of the subalpine to alpine plant species Saussurea discolor (Willd.) DC., and Saussurea pygmaea (Jacq.) Spreng., (Asteraceae) has been investigated by means of light and fluorescence microscopy on specimens of Austrian provenance. Both species develop a so called interxylary cork which mediates the splitting of the root into various strands. This phenomenon takes place in the secondary xylem and involves the development of a periderm separating the originally solid xylem cylinder. Interxylary cork is currently known from approximately 40 species of the Dicotyledones. This is the first report of this specific anatomical structure from the two studied species.

Abstract The isolation of well formed crystals of the biomineral weddellite (calcium oxalate dihydrate) from Chamaecereus silvestrii, a Cactaceae species found in the northern part of Argentina, is described. Infrared spectroscopic measurements allow an unambiguous characterization of the nature of the crystals. This is the first report of the presence of a biomineral in this plant species.

To the best of our knowledge, this is the first report of TCSV infection of H. wayetii and S. truncata from any location, although other tospoviruses are known to infect these and related plant species. The identification of these two diverse plant species as the first reported natural ornamental hosts of TCSV has implications for TCSV epidemiology and management in ornamental and vegetable crops, which frequently share production space.
