The Leaf Blade of Grasse

In grasses, the leaf blades usually grow more in length than in any other direction. Some grasses have very short leaves, others very long ones. The veins in the leaf blade can usually be seen on holding the leaf up to the light. In most cases, the mid rib is prominent, and in some cases there may also be a distinct keel amongst the veins running through the leaf blade. Blunt or obtuse tips are not altogether absent, but it is not a common feature. Sometimes the margins are glandular, as an aregrostis wildinoviana, and aragrostis major.
