That part of the leaf, which spreads away from the culm, is known us the Blade or lamina^ and is usually sessile and slender, tapering to a point. To the ordinary observer the blades of grasses seem to be very nearly alike. Even Linnants thought so, but to the botanist of to-day they j)resent very marked differences. The abortive leaves on root-stocks generally consist mainly of rudimentary sheaths. Commonly, all the leaves on a stem are much alike, but in some cases the lower leaves are quite unlike those above. The lower leaves of some species of Bambusa (bamboo), Ori/zopsis asj^crifoUa (mountain rice), Fanicum.
