Axillary buds are located at the intersection of the leaf and stem of a plant. The axillary bud (or lateral bud) is an embryonic or organogenic shoot located in the axil of a leaf. Each bud has the potential to form shoots, and may be specialized in producing either vegetative shoots (stems and branches) or reproductive shoots . Once formed, a ...
In many of the latter, buds are even more reduced, often consisting of undifferentiated masses of cells in the axils of leaves. A terminal bud occurs on the end of a stem and lateral buds are found on the side. A head of cabbage (see Brassica) is an exceptionally large terminal bud, while Brussels sprouts are large lateral buds. [citation needed]
(of a compound leaf) Having precisely two leaflet s, usually in a symmetrical pair, e.g. a leaf of Colophospermum mopane. Compare jugate lobed leaf, e.g. most species of Bauhinia. bifusiform Fusiform with a pinch in the middle. bilabiate Having two lips, e.g. the form of the petal s in many irregular flowers. bilateral 1.
A leaf (pl.: leaves) is a principal appendage of the stem of a vascular plant, [1] usually borne laterally above ground and specialized for photosynthesis.Leaves are collectively called foliage, as in "autumn foliage", [2] [3] while the leaves, stem, flower, and fruit collectively form the shoot system.

Chart illustrating leaf morphology terms. The following terms are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (that is, the leaf blade or 'lamina' is undivided) or compound (that is, the leaf blade is divided into two or more leaflets). [1]
Leaf axils – the space created between a leaf and its branch. This is especially pronounced on monocots like the bromeliads. Leaf buds – buds that produces leafy shoots. Leaf scar – the mark left on a branch from the previous location of a bud or leaf.
Spurs are perennial growths and commonly arise from the leaf axils on shoots. They are common in fruit trees such as Apple, Pear, Plum and Almond. The spurs have horticultural importance. For example, the number of spurs on an almond (Prunus dulcis) tree is highly connected to the overall almond yield. [2]
They come from the axils of the bud scales, and the leaves from the Ginkgo tree spur shoots. Pollen is contained in sacs of two to four at the tips of sporophylls on the strobiloid. Ovules of Ginkgo trees come from stalks from leaf axils on the short shoots, each containing two ovules. The ovule is fertilized by the flagellated male gametes ...
