L. thelypteris (pinna). but without the short lobes commencing near the base which are characteristic of that species. They are of a delicate green, and tall, attaining in favourable situations over a yard in height. Its culture is easy if boggy, peaty conditions and plenty of moisture be provided. We produced a rampant specimen by planting a piece of the creeping caudex in peaty soil, over a good-sized glazed earthenware pan sunk in the ground and filled with pieces of broken brick, over which moss was laid to prevent admittance of the soil. Every rainfall or watering was caught by this pan, and obviously the roots proper of the thirsty Fern obtained admission to this supply, for the creeping rootstocks spread, and even emerged in all directions, and had eventually to be drastically checked to prevent monopoly of valuable space. Peaty soil, in pans, kept well watered, suits the Fern admirably, though owing to its tall growth and slender stalks it does not rank among the decoratives. No variety has been found in this country, but a very good crested form, L. t. polydactyla (Pufferae), was found some years ago by a lady in the United States, and figures in our collection as, if not a British find, at any rate a " sport " of a British species, and there are some very promising grandiceps forms raised by the Please note that these images are extracted from scanned page image
