Identification; Ferns. 416 THE BOOK OF CHOICE The fertile fronds are very similar in shape and size, but are furnished with much narrower leaflets.—Lowe, Our Native Ferns, ii., p. 385, t. 59a. L. S. trinervis—trin-er'-vis (three-nerved), Lowe. This remarkably handsome variety, originally found on the Sugar-loaf Mountains, in Wicklow, differs from all other known forms through the division of the barren fronds (Fig. 105) into three sections near the base, where one lateral branch is produced on either side of the central one, which is usually much larger than the lateral ones. The fertile fronds, which are but sparingly produced—seldom more than two on a plant—are branched at the base in the same way. Sometimes the summit of the fronds, and the extremity of the branches, are forked or even terminated by a crest of very distinct character ; it is then called L. S. t. coronans (Fig. 106).—Lowe, Our Native Ferns, ii., p. 400. Nicholson, Dictionary of Gardening, ii., p. 295. L. S. variabilis — var-i-a'-bil-is (variable), Moore. A variety of small dimensions, with barren fronds 4in. to 5in. long, enlarging upwards for about one-third of their length, and then suddenly contracting ; they frequently branch towards or at the point, and diminish near the stalk, with here and there a projecting leaflet.— Nicholson, Dictionary of Gardening, ii., p. 295.
