Sessility (botany) subsessile, which is not completely sessile. Sessility (botany) In botany, sessility (meaning "sitting", used in the sense of "resting on the surface") is a characteristic of plant parts that have no stalk. Flowers or leaves are borne directly from the stem or peduncle, and thus lack a petiole or pedicel. The leaves of most monocotyledons lack petioles. The term sessility is also used in mycology to describe a fungal fruit body that is attached to or seated directly on the surface of the substrate, lacking a supporting stipe or pedicel. Other examples of sessile flowers include Achyranthus, Saffron, etc. Plant
Ramification (botany) Ramification (botany) In botany, ramification is the divergence of the stem and limbs of a plant into smaller ones, i.e. trunk into branches, branches into increasingly smaller branches, etc. Gardeners stimulate the process of ramification through pruning, thereby making trees, shrubs and other plants bushier and denser. Short internodes (the section of stem between nodes, i.e. areas where leaves are produced) help increase ramification in those plants that form branches at these nodes. Long internodes (which may be the result of over-watering, the over-use of fertilizer, or a seasonal "growth spurt") decrease a gardener's ability to induce ramification in a
