During the peak years of Pteridomania (the Victorian enthusiasm for ferns) between 1860 and 1870, the hunting of ferns became a popular Sunday activity. These fern hunters would roam across Britain searching for new or interesting plants. Unlike much of the plant collecting at that time, this was a pursuit undertaken by many ladies who took cuttings to replant in their own gardens and terrariums. Often the collector who originally discovered the new fern would be commemorated in its name. This specimen is one such example Dryopteris filix-mas 'Bollandiae' has been found only once by Mrs Bolland near Tunbridge Wells, Kent. This fern does not produce fertile spores. There are unproven suggestions that it might be a hybrid of Dryopteris filix-mas and Dryopteris dilatata, although more work will be needed to confirm this.
