Here we discuss the genes that function in simple and compound leaf development, such … rosulate. These leaflets from lobes and each palmate compound leaf may contain two or more lobes. A compound leaf has a fully subdivided blade, each leaflet of the blade being separated along a main or secondary vein. having lobes radiating from a common point — see leaf illustration. The ontogenetic relationship of the dicot compound leaf to the simple leaf is unclear (Merrill, 1986a, 1986b). Thus, a compound leaf has more leaflets than a simple leaf. The vein in the center of the leaf that kind of cuts the leaf in half is the midrib. Examples: Citrus limon (lemon), Citrus maxima (papanas). Thick, succulent leaf. However, the leaf may be dissected to form lobes, but the gaps between lobes do not reach to the main vein. There is almost always a bud (tiny growing point) found in the angle between the petiole and the stem (leaf axil). A simple leaf has an undivided blade. The pinnate leaves are then further subdivided into different classes according to the leaf arrangement on the rachis. Simple leaves have axillary buds present in their axils, while compound leaves do not. https://www.britannica.com/science/palmately-compound-leaf.
