In Pisum sativum foliaceous stipules are much developed and upper leaflets are modified into tendrils. Stipules frequently fall off early in life and following such an event, their occurrence can only be inferred by the presence of scars on the stem. Very often the mature foliar stomata are paracytic with 2 parallel subsidiaries and 1 or more parallel encircling cells but the stomata in the sheathing stipules and perianth lobes are usually anomocytic. Interfoliar definition is - borne between the leaves; especially : borne between opposite or verticillate leaves. Therefore, they are flat leafy structures found below the leaf. In the case of alternate leaves, the stipule s at the base of each leaf are sometimes united to the petiole and to each other, so as to form an adnate, … also have large colleters, up to 1100 μm feature is a family-level taxonomic character.

Foliar feeding is a technique of feeding plants by applying liquid fertilizer directly to the leaves. A stipule is considered to be "abaxial", "counter" or "leaf opposed" if it's located on the opposite side to where the leaf meets the stem.[4][7]. Though the foliar anomaly in this group was early remarked upon and was anntomicnlly esplsined as early as 1840,* there are considerations which mnke its present discussion desirable. Interpetiolar: The stipules of two opposite leaves unite by their outer margins and form a structure lying in between the petioles of the two leaves, e.g. In botany, a stipule is an outgrowth borne on either side (sometimes just one side) of the base of a leafstalk (the petiole).
