Hi, my name is Erwin, native to Styria, a province at SE Austria. Am botanist, generally interested in all kinds of plants, still as there are so many, many flowering plants, i usually try to reduce my activities to ferns, sometimes gymnosperms, surely often cross those limits, loosing myself in "diversity of life". !Back to ferns! Estimated 20ys ago it was easy to buy fresh, imported leaves of Polystichum munitum as part of floristic arrangements, as these had been traded then. No idea when this stopped, and for what reason, trends surely are changing. Was no problem at all, in case i didn't wish to have fresh, viable spores of this fern for to grow new plants to study their growth potential and at 2nd step to try producing hybrids with congeneric species. Hence my question: does anyone know why this trade has been stopped? I do remember to have seen leaves with mature sori (sporangia clusters) when leaves were traded, which had would been a good source for propagation.
