The document discusses nodal anatomy in plants. It defines a leaf gap as the area along the stem where phloem and xylem diverge from the vascular cylinder and enter the base of a leaf. It also mentions that leaves can be trilacunar, with stipules, or multilacunar, with a leaf sheath. The document examines the anatomy above, at, and below the node.
