. Our ferns in their haunts; a guide to all the native species. Ferns. 62 THE MOONWORT AND ITS ALLIES. matricaria;folium that have grown in situations uiisuited to them. They would therefore seem more properly named B. niatricariwfoliiiin tenebrosum. The smallest are only an inch high with tiny threadlike steins and minute fertile and sterile parts, while the larger sometimes reach a length of nine inches. They can hardly be called nine inches high, since in such specimens the stem is usually decumbent with two or three inches of the stipe under ground. Lik-e B. simplex, this form is ex- / tremely variable. In speaking of it at the Boston Meeting of the Fern Chap- ter in 1898, Mr. Eaton said : "The av- erage height above ground is two inches and most commonly the sterile lamina is sessile or slightly stalked, less than one quarter of an inch long, the edge inflexed and top bent down just as it covered the fertile divison. . In this state the sterile division bears one lobe or notch on each side and the apex is emarginate. Often it bears a sporangium and may even bear one or two on each lobe. From this there may be found a regular series up to the fully developed form, one and three fourths of an inch long, of which three fourths of an inch is petiole. There are in this two or three pairs of Boiryc/tmm mairicaria- semi-lunate lobcs, the lower of which /oiiuvttenebr^^um. ^^^ alternate and all decurrent. . In small specimens the fertile division is overtopped by the sterile, but in the larger plants, the sterile division.
