The hop (Humulus) is a small genus of flowering plants, native to the temperate Northern Hemisphere. The female flowers, commonly called hops, are used as flavoring and stabilizers during beer brewing. The hop is part of the family Cannabaceae, which also includes the genus cannabis (also known as hemp). Hops are the female flower cones of the hop plant (Humulus lupulus). They are used primarily as a flavoring and stability agent in beer, and also in other beverages and in herbal medicine. The first documented use in beer is from the eleventh century. Hops contain several characteristics favorable to beer, balancing the sweetness of the malt with bitterness, contributing flowery, citrus, fruity or herbal aromas, and having an antibiotic effect that favors the activity of brewer's yeast over less desirable microorganisms. The hop plant is a vigorous climbing herbaceous perennial, usually grown up strings in a field called a hopfield, hop garden or hop yard. Many different varieties of hops are grown by farmers all around the world, with different types being used for particular styles of beer.

Crocus (plural: crocus, crocuses) is a genus of perennial flowering plants, native to a large area from coastal and subalpine areas of central and southern Europe (including the islands of the Aegean), North Africa and the Middle East, across Central Asia to western China. The genus Crocus is placed botanically in the iris family (Iridaceae). The plants grow from corms and are mainly hardy perennials, and are found in a wide range of habitats, including woodland, scrub and meadows. There are about eighty species of crocus (of which approximately 30 are cultivated). Their cup-shaped, solitary, salverform flowers taper off into a narrow tube. Their color varies enormously, although lilac, mauve, yellow and white are predominant. The grass-like, ensiform leaf shows generally a white central stripe along the leaf axis. The leaf margin is entire. All crocuses typically have three stamens. The spice saffron is obtained from the stigmas of Crocus sativus, an autumn/fall-blooming species.

Cirsium arvense is a species of Cirsium, native throughout Europe and northern Asia, and widely introduced elsewhere. The standard English name in its native area is Creeping Thistle. It is a tall herbaceous perennial plant, forming extensive clonal colonies from an underground root system that sends up numerous erect stems each spring, reaching 1–1.2 m tall (occasionally more); the stems often lie partly flat by summer but can stay erect if supported by other vegetation. The leaves are very spiny, lobed, up to 15–20 cm long and 2–3 cm broad (smaller on the upper part of the flower stem). The inflorescence is 10–22 mm diameter, pink-purple, with all the florets of similar form (no division into disc and ray florets). The flowers are usually dioecious, but not invariably so, with some plants bearing hermaphrodite flowers. The seeds are 4–5 mm long, with a feathery pappus which assists in wind dispersal.

Safflower (Carthamus tinctorius L.) is a highly branched, herbaceous, thistle-like annual, usually with many long sharp spines on the leaves. Plants are 30 to 150 cm tall with globular flower heads (capitula) and commonly, brilliant yellow, orange or red flowers which bloom in July. Each branch will usually have from one to five flower heads containing 15 to 20 seeds per head. Safflower has a strong taproot which enables it to thrive in dry climates, but the plant is very susceptible to frost injury from stem elongation to maturity.

Externally the temples presented only masses of unbroken wall; but these, as well as the pylons, were covered with huge pictures of a historical character. Only in the tombs do we find painted ornament of a purely conventional sort. Rosettes, diaper patterns, spirals, and checkers are to be met with in them; but many of these can be traced to symbolic origins.

The purely conventional ornaments — the rosette, guilloche, and lotus-flower, and probably also the palmette — were derived from Egyptian originals. They were treated, however, in a quite new spirit and adapted to the special materials and uses of their environment. Thes the form of the palmette, even if derived, as is not likely, from the Egyptian lotus-motive, was assimilated to the more familiar palm-forms of Assyria.

The flowers are produced in open cymes, the individual flowers are white having corolla with a basal tube 13–25 mm long and five lobes 13–22 mm long. The flower's fragrance is unique and sweet. It is widely cultivated as an ornamental plant in warm temperate and subtropical regions.

A Rose window (or Catherine window) is often used as a generic term applied to a circular window, but is especially used for those found in churches of the Gothic architectural style and being divided into segments by stone mullions and tracery. The name "rose window" was not used before the 17th century and according to the Oxford English Dictionary, among other authorities, comes from the English flower name rose.

Dodder) is a genus of about 100-170 species of yellow, orange or red (rarely green) parasitic plants. Formerly treated as the only genus in the family Cuscutaceae, recent genetic research by the Angiosperm Phylogeny Group has shown that it is correctly placed in the family Convolvulaceae. The genus is found throughout the temperate to tropical regions of the world, with the greatest species diversity in subtropical and tropical regions; the genus becomes rare in cool temperate climates, with e.g. only four species native to northern Europe.

Jain caves reveal specific dimensions of Jain philosophy and tradition. They reflect a strict sense of asceticism &ndash; they are not relatively large as compared to others, but they present exceptionally detailed art works. The most remarkable Jain shrines are the <em>Chhota Kailash</em> (cave 30), the <em>Indra Sabha</em> (cave 32) and the <em>Jagannath Sabha</em> (cave 33). The <em>Indra Sabha</em> is a two storeyed shrine with a very fine carving of the lotus flower on the ceiling. In another cave, an imposing image of Ambika, the Yakshi (dedicated attendant deity) of Neminatha is found seated on her lion under a mango tree, laden with fruits. All other Jain caves are also characterized by intricate detailing. Many of the structures had rich paintings in the ceilings - fragments of which are still visible.

Narcissus is the botanic name for a genus of mainly hardy, mostly spring-flowering, bulbs in the Amaryllis family native to Europe, North Africa, and Asia. There are also several Narcissus species that bloom in the autumn. Though Hortus Third cites 26 wild species, Daffodils for North American Gardens cites between 50 and 100 excluding species variants and wild hybrids. Through taxonomic and genetic research, it is speculated that over time this number will likely continue to be refined. Daffodil is a common English name, sometimes used now for all varieties, and is the chief common name of horticultural prevalence used by the American Daffodil Society The range of forms in cultivation has been heavily modified and extended, with new variations available from specialists almost every year.
