The creeping stem lies flat upon the ground, and often attains a great lengtli, sending up at intervals erect branches Avith crowded linear-awl-shaped leaves, some of wliich, like tiio one shown in tlie figure, are terminated by a slender peduncle bearing one or more cylindrical spikes. These are the fertile branches, and the leaves u})on them, or at all events upon the slender upper part, are very much smaller than upon the ordinary sterile branches. It is to be o])served that the stems and ro'^ts of these jjlants branch (licliotomouslij (145,. 333. The sporangia are produced in the axils of the leavers of the terminal spike. One of these leaves, greatly magnified, with its attached sporangium, is shown in Fig. 238. The sporangium opens by a slit at the top to discharge the spores. 334.
