CULTIVATION OF THE FULLER'S TEASEL IN ESSEX 285 Pteris aquilina (Brake or Bracken).—Very common and abundant. Polypodium+ vulgare (Polypody).—A Fern found on pollarded hornbeams and old stumps. Used to be abundant, but has been reduced in numbers by the continued removal of the roots. Ophioglossum vulgatum (the Adder's-tongue).—This species is not well known, as it dies away early in the summer and is only to be found by careful searching. Very abundant in places, and, I am glad to say, increasing in numbers. Lastrea filix-mas (Male-fern).—A fairly common plant, but does not grow in the forest to any great size. I have found only one really fine specimen. Athyrium felix-faemina (Lady-fern).—Not quite so common as the Male-fern, but there are some fine plants still existing. Lastrea dilatata (Broad Buckler-fern).—This is found often in the forest, but all the finest specimens have been removed one by one, and consequently the plants remaining average small size, with but lew exceptions. Lastrea Oreopteris (montanum) (Mountain Buckler Fern), and Blechnum spicant (Hard Fern) grow together in one or two places, but are not common. Polypodium dryopteris (Oak-fern) and Asplenium trichomanes (Maidenhair Spleenwort).—Both these have been recorded in one or two places, but have now disappeared. These are the species which I have found actually growing in the forest, and I have photographs and preserved fronds of most of these for members to examine. I have also found Polystichum aculeatum, Asplenium ruta-muraria and Asplenium adiantum-nigrum in the neighbourhood of the forest, but not actually within its boundaries. CULTIVATION OF THE FULLER'S TEASEL IN ESSEX. By ALFRED W. DENNIS. (With Plate XIX.) IN August, 1909, while staying at an old farmhouse called Don John's, near Halstead, Essex, I was much surprised to find the Fuller's Teasel, Dipsacus fullonum, in cultivation at Burton's Green, a hamlet near by. I had sup-
