Tanacetum Vulgare
Tansy (''Tanacetum vulgare'') is a perennial, herbaceous flowering plant in the genus ''Tanacetum'' in the aster family, native to temperate Europe and Asia. It has been introduced to other parts of the world, including North America, and in some areas has become invasive. It is also known as common tansy, bitter buttons, cow bitter, or golden buttons. The Latin word ''vulgare'' means "common". Description Tansy is a flowering herbaceous plant with finely divided compound leaves and yellow, button-like flowers. It has a stout, somewhat reddish, erect stem, usually smooth, tall, and branching near the top. The leaves are alternate, long and are pinnately lobed, divided almost to the center into about seven pairs of segments, or lobes, which are again divided into smaller lobes having saw-toothed edges, giving the leaf a somewhat fern-like appearance. The roundish, flat-topped, button-like, yellow flower heads are produced in terminal clusters from mid-to-late summer. The ...

Bract
In botany, a bract is a modified or specialized leaf, especially one associated with a reproductive structure such as a flower, inflorescence axis or cone scale. Bracts are usually different from foliage leaves. They may be smaller, larger, or of a different color, shape, or texture. Typically, they also look different from the parts of the flower, such as the petals or sepals. A plant having bracts is referred to as bracteate or bracteolate, while one that lacks them is referred to as ebracteate and ebracteolate, without bracts. Variants Some bracts are brightly-coloured and serve the function of attracting pollinators, either together with the perianth or instead of it. Examples of this type of bract include those of ''Euphorbia pulcherrima'' (poinsettia) and ''Bougainvillea'': both of these have large colourful bracts surrounding much smaller, less colourful flowers. In grasses, each floret (flower) is enclosed in a pair of papery bracts, called the lemma (lower bract) and p ...

Tanacetum Cinerariifolium
''Tanacetum cinerariifolium'' is a species of flowering plant in the aster family, Asteraceae, and formerly part of the genus ''Pyrethrum'', but now placed in the genus '' Chrysanthemum'', or the genus ''Tanacetum'' by some biologists. It is called the Dalmatian chrysanthemum, denoting its origin in that region of Europe (Dalmatia). It looks more like the common daisy than other pyrethrums do. Its flowers, typically white with yellow centers, grow from numerous fairly rigid stems. Plants have blue-green leaves and grow to 45 to 100 cm (18 to 39 in) in height. As an insecticide The plant is economically important as a natural source of an insecticide called "pyrethrum." The flowers are pulverized and the active components, called pyrethrins, contained in the seed cases, are extracted and sold in the form of an oleoresin. This is applied as a suspension in water or oil, or as a powder. Pyrethrins attack the nervous systems of all insects, and inhibit female mosquitoes from b ...

Tanacetum Camphoratum
''Tanacetum camphoratum'' is a species of flowering plant in the aster family known by the common names camphor tansy and dune tansy. It is native to the Pacific Coast of North America from British Columbia to California, where it grows in sand dunes and other coastline habitat. This species may be known by the synonym ''Tanacetum douglasii'' and is often included in ''Tanacetum bipinnatum''. It is a rhizomatous perennial herb with a thick, low-lying stem up to 25 centimeters long, branching to form a mass of vegetation. It is hairy, glandular, and aromatic, with a camphor scent. The leaves are up to 25 centimeters long and thick but featherlike, divided into many narrow leaflets on each side of the main rachis. Each leaflet in turn has many segments along each side, and the segments are usually divided into several small, knobby segments with folded or curled edges. The inflorescence bears up to 15 flower heads, each about a centimeter wide or slightly wider. Each head contain ...
