At one end of each rail the flange spread out to form a foot which rested on a cross sleeper, being secured to the latter by a spike passing through a central hole, and above this foot the rail was so shaped as to form a socket into which was fitted the end of the next rail.
The membranous spathes have been cut and drawn aside, revealing the spike of fruit which bears the long silky styles.
They however occur in a whole section of Andropogon, in Anomochloa, and at the base of the spike in Sesleria.
A long leaf (spathe) borne immediately below the spike forms an apparent continuation of the scape, though really a lateral outgrowth from it, the spike of flowers being terminal.
Long and about an inch wide, closely arranged in two rows as in the true Flag (Iris); the tall, flowering stems (scapes), which very much resemble the leaves, bear an apparently lateral, blunt, tapering spike of densely packed, very small flowers.
The spike is most simple in Ophioglossum, where it bears on each side a row of large sporangia, which hardly project from the surface, the vascular bundles occupying a central position.
The grains of both are very small, only one half as long as those of common millet, but are exceedingly prolific. Many stalks arise from a single root, and a single spike often yields 2 oz.
The horizon was full of peaks like the teeth of a saw, so numerous as to be nearly indistinguishable from one another, except for the occasional spike that rose above its companions.
Narrower at the top and surmounted by a spike it distinguishes the Assyrian kings.
Some of the emperors wore crowns on occasion, as Caligula and Domitian, at the games, and stellate or spike crowns are depicted on the heads of several of the emperors on their coins, but no idea of imperial sovereignty was indicated thereby.
