A plant genus of the family ASTERACEAE that is similar to CONYZA. Members contain SESQUITERPENES.
A large plant family of the order Asterales, subclass Asteridae, class Magnoliopsida. The family is also known as Compositae. Flower petals are joined near the base and stamens alternate with the corolla lobes. The common name of "daisy" refers to several genera of this family including Aster; CHRYSANTHEMUM; RUDBECKIA; TANACETUM.
5,7,4'-trihydroxy-flavone, one of the FLAVONES.
The above-ground plant without the roots.
A plant genus of the family ASTERACEAE. Members contain arctiin and onopordopicrin.
Lists of words, usually in alphabetical order, giving information about form, pronunciation, etymology, grammar, and meaning.
A plant species of the family FABACEAE used to study GENETICS because it is DIPLOID, self fertile, has a small genome, and short generation time.
A plant genus of the family ASTERACEAE with strong-smelling foliage. It is a source of SANTONIN and other cytotoxic TERPENES.
The sixth planet in order from the sun. It is one of the five outer planets of the solar system. Its twelve natural satellites include Phoebe and Titan.
Seedless nonflowering plants of the class Filicinae. They reproduce by spores that appear as dots on the underside of feathery fronds. In earlier classifications the Pteridophyta included the club mosses, horsetails, ferns, and various fossil groups. In more recent classifications, pteridophytes and spermatophytes (seed-bearing plants) are classified in the Subkingdom Tracheobionta (also known as Tracheophyta).
The reproductive organs of plants.
Expanded structures, usually green, of vascular plants, characteristically consisting of a bladelike expansion attached to a stem, and functioning as the principal organ of photosynthesis and transpiration. (American Heritage Dictionary, 2d ed)
An order of protozoa characterized by their ability to aggregate to form a multicellular pseudoplasmodium, which gives rise to a multispored fruiting body. A stalk tube is present.
A plant genus in the family PINACEAE, order Pinales, class Pinopsida, division Coniferophyta. They are coniferous evergreen trees and should not be confused with hemlock plants (CICUTA and CONIUM).
The rose plant family in the order ROSALES and class Magnoliopsida. They are generally woody plants. A number of the species of this family contain cyanogenic compounds.
Slender-bodies diurnal insects having large, broad wings often strikingly colored and patterned.
The scroll-like bony plates with curved margins on the lateral wall of the NASAL CAVITY. Turbinates, also called nasal concha, increase the surface area of nasal cavity thus providing a mechanism for rapid warming and humidification of air as it passes to the lung.
A chronic form of cutaneous lupus erythematosus (LUPUS ERYTHEMATOSUS, CUTANEOUS) in which the skin lesions mimic those of the systemic form but in which systemic signs are rare. It is characterized by the presence of discoid skin plaques showing varying degrees of edema, erythema, scaliness, follicular plugging, and skin atrophy. Lesions are surrounded by an elevated erythematous border. The condition typically involves the face and scalp, but widespread dissemination may occur.
A short thick vein formed by union of the superior mesenteric vein and the splenic vein.
PLANTS, or their progeny, whose GENOME has been altered by GENETIC ENGINEERING.
Concentrated pharmaceutical preparations of plants obtained by removing active constituents with a suitable solvent, which is evaporated away, and adjusting the residue to a prescribed standard.
