. The fern allies of North America north of Mexico. Pteridophyta; Botany. THE TRAILING LYCOPODIUMS. L. Fernald thinks our plant should have a different name. He has recently proposed to call it ;'iy flabel- liforme. There seems to be good reason for thinking that the Linnaean plant is represented in our far North- or, rather, that our plant with spreading fan-shaped branches tends to bear these branches erect as one pro- ceeds northward. Growing with the common ground-pine, and seldom distinguished from it by the novice, may often be found specimens in which the branchlets are more erect and in which the under row of leaves scarcely differs iii size from the upper and lateral rows. This has usually been regard ed as a fairly distinct variety or species named chaiiicecy- parissus. In contradistinction to the type, the main stem is quite like a rootstock, being pale, slender, and buried several inches in the earth. The foliage is often lighter in colour, and the branchlets also more inclined to lengthen at the tips the second season than in Lycopodiitiii complanatuiii, and wliile they are not spreading they are more or less flattened, as in the other. The fruiting parts are exactly like those of Lycopodiitm coniplauatitin but are said to ripen their spores two or three weeks earlier. This latter feature, however, seems to depend entirely upon the soil and surroundings of the plant. ChamcEcy- Upper and under ^ I J surface of Branchlet. parissiis is rarely if ever found growing alone, and the invariable proximity of specimens of Lycopodhnii coinplanatiim suggests that it is only a strong and well-marked form, due, perhaps, to the main stem being accidentally covered with earth.
