FrondA frond is a large, divided leaf. In both common usage and botanical nomenclature, the leaves of ferns are referred to as fronds and some botanists restrict the term to this group. Other botanists allow the term frond to also apply to the large leaves of cycads, as well as palms (Arecaceae) and various other flowering plants, such as mimosa or sumac.
FernClass of vascular plants Ferns (Polypodiopsida or Polypodiophyta) are a group of vascular plants that reproduce via spores and have neither seeds nor flowers. They reproduce in two phases, a short-lived gametophyte that reproduces sexually to develop a spore-bearing leaf structure. Some ferns produce coiled fiddleheads, which expand into fronds. The group includes over 10,500 extant species.
FiddleheadFiddleheads or fiddlehead greens are the furled fronds from a fledgling fern, harvested for use as a vegetable. Left on the plant, each fiddlehead would unroll into a new frond (circinate vernation). As fiddleheads are harvested early in the season, before the frond has opened and reached its full height, they are cut fairly close to the ground. Fiddleheads from brackens contain ptaquiloside, a compound associated with bracken toxicity, and thiaminase.
Spring (season)Spring, also known as springtime, is one of the four temperateseasons, succeeding winter and preceding summer. There are various technical definitions of spring, but local usage of the term varies according to local climate, cultures and customs. When it is spring in the Northern Hemisphere, it is autumn in the Southern Hemisphere and vice versa.
Leaflet (botany)A leaflet (occasionally called foliole) in botany is a leaf-like part of a compound leaf. Though it resembles an entire leaf, a leaflet is not borne on a main plant stem or branch, as a leaf is, but rather on a petiole or a branch of the leaf. Compound leaves are common in many plant families and they differ widely in morphology. The two main classes of compound leaf morphology are palmate and pinnate.
PhotosynthesisPhotosynthesis is a system of biological processes by which photopigment-bearing autotrophic organisms, such as most plants, algae and cyanobacteria, convert light energy—typically from sunlight—into the chemical energy necessary to fuel their metabolism. The term photosynthesis usually refers to oxygenic photosynthesis, a process that releases oxygen as a byproduct of water splitting.
CrozierA crozier or crosier (also known as a paterissa, pastoral staff, or bishop's staff) is a stylized staff that is a symbol of the governing office of a bishop or abbot and is carried by high-ranking prelates of Roman Catholic, Eastern Catholic, Eastern Orthodox, Oriental Orthodox, Malankara Mar Thoma Syrian Church, Church of South India and some Anglican, Lutheran, United Methodist and Pentecostal churches.
ShepherdA shepherd is a person who tends, herds, feeds, or guards flocks of sheep. Shepherding is one of the world's oldest occupations; it exists in many parts of the globe, and it is an important part of pastoralist animal husbandry. Because the occupation is so widespread, many religions and cultures have symbolic or metaphorical references to shepherds. For example, Jesus called himself the Good Shepherd, and ancient Greek mythologies highlighted shepherds such as Endymion.

BudIn botany, a bud is an undeveloped or embryonic shoot and normally occurs in the axil of a leaf or at the tip of a stem. Once formed, a bud may remain for some time in a dormant condition, or it may form a shoot immediately. Buds may be specialized to develop flowers or short shoots or may have the potential for general shoot development. The term bud is also used in zoology, where it refers to an outgrowth from the body which can develop into a new individual.
Scroll (art)The scroll in art is an element of ornament and graphic design featuring spirals and rolling incomplete circle motifs, some of which resemble the edge-on view of a book or document in scroll form, though many types are plant-scrolls, which loosely represent plant forms such as vines, with leaves or flowers attached.
