Spear grass is a herbaceous grass often troublesome in gravel walks and on hard, dry soils. The general appearance of plants is often modified by climate, soil, and modes of cultivation. In this magnified pistil, we see the nectary, composed of one or two fleshy scales, and the germ, ovary, or seed-bearing portion of the pistil. The stamens seen in the same figure, consisting each of a bag filled with a fine powder or pollen, supported upon a stalk or filament which is analogous to the stalk or stem of a leaft. The bag hold the pollen, called the anther.
