Elementary botany . elementarybotany00atki Year: 1898 CHAPTER XXVIII. CLUB MOSSES. 386. What are called the '' club mosses'' make up another group oi interesting plants which rank as allies of the ferns. They are not of course true mosses, but the general habit of some of the smaller species, and especially the form and size of the leaves, suggest a resem- blance to the larger of the moss plants. 387. The clavate lyeopodium.—Here is one of the club mosses (fig. 238) which has a wide distribution and which is well entitled to hold the name of (dub because of the form of the up- right club-shaped branches. As will be seen from the illustration, it has a prostrate stem. This stem runs for considerable distances on the surface of the ground, often partly buried in the leaves, and sometimes even buried beneath the soil. The leaves are quite small, are flat- tened-awl-shaped, and stand thickly over the stem, arranged in a spiral manner, which is the usual arrangement of the leaves of the club mosses. Here and there are upright branches which are forked several times. The end of one or more of these branches becomes pro- duced into a slender upright stem which is T ' 1 ° Lyeopodium c 1 u v a - nearlv leafless, the leaves being reduced to tum, branch bearing two o fruiting spikes; at right mere scales. The end of this leafless branch sporophyll with open sporangium : single then terminates in one or several cylindrical sPorenearit- heads which form the club. 191
