Liatris Ligulistylis
''Liatris ligulistylis'' (Rocky Mountain blazing star, northern plains blazing star, or meadow blazing star) is a flowering plant of the family Asteraceae, native to the central United States and central Canada. Description The leaves have whitish midribs, and are positioned basally and mostly alternately on the stem. They vary from linear and sessile nearer the top of the plant, to oblanceolate with petioles nearer the bottom. The stem is up to . The stem and leaves are sparsely to densely covered with short white hairs. There are 4–21 flowers arranged in a loose raceme on the upper part of the stem, with rounded pinkish purple flower heads on stems. Each flower head has 30-100 five-lobed, tubular flowers surrounded by spoon-shaped bracts ( phyllaries) with translucent, jagged, and often purple edges that fold inward. Each flower has a long, thread-like, divided style protruding from the center. The fruits ( cypselae) are long, each with a ring ( pappus) of barbed ...

Liatris Ligulistylis 1
''Liatris'' (), commonly known as gayfeather and blazing star. is a genus of flowering plants in the tribe Eupatorieae within the family Asteraceae native to North America (Canada, United States, Mexico and the Bahamas). Some species are used as ornamental plants, sometimes in flower bouquets. They are perennials, surviving the winter in the form of corms. ''Liatris'' species are used as food plants by the larvae of some Lepidoptera species including the flower moths ''Schinia gloriosa'' and ''Schinia sanguinea'', both of which feed exclusively on the genus, and '' Schinia tertia'' and ''Schinia trifascia''. Classification ''Liatris'' is in the tribe Eupatorieae of the aster family. Like other members of this tribe, the flower heads have disc florets and no ray florets. ''Liatris'' is in the subtribe Liatrinae along with ''Trilisa'', ''Carphephorus'', and other genera. ''Liatris'' is closely related to ''Garberia'', a genus with only one species endemic to Florida.

Phyllaries
In botanical terminology, a phyllary, also known an involucral bract or tegule, is a single bract of the involucre of a composite flower. The involucre is the grouping of bracts together. Phyllaries are reduced leaf-like structures that form one or more whorls immediately below a flower head. Function Phyllaries provide protection to developing flowers and fruits. In the dandelion hybrid ''Taraxacum japonicum'' × ''officinale'', recurved phyllaries help defend the flowers from herbivory by slugs. They sometimes assist in the dispersal of fruits. The hooked phyllaries of burdock species (''Arctium'') cling to the fur and feathers of animals, dispersing the seeds away from the parent plant (exozoochory). Structure and arrangement Phyllary morphology is useful in plant identification as between species of the Asteraceae The family Asteraceae, alternatively Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales.

Monarch Butterfly
The monarch butterfly or simply monarch (''Danaus plexippus'') is a milkweed butterfly (subfamily Danainae) in the family Nymphalidae. Other common names, depending on region, include milkweed, common tiger, wanderer, and black-veined brown. It is amongst the most familiar of North American butterflies and an iconic pollinator, although it is not an especially effective pollinator of milkweeds. Its wings feature an easily recognizable black, orange, and white pattern, with a wingspan of . A Müllerian mimic, the viceroy butterfly, is similar in color and pattern, but is markedly smaller and has an extra black stripe across each hindwing. The eastern North American monarch population is notable for its annual southward late-summer/autumn instinctive migration from the northern and central United States and southern Canada to Florida and Mexico. During the fall migration, monarchs cover thousands of miles, with a corresponding multigenerational return north in spring. The western ...

Liatris Aspera
''Liatris aspera'' (known as rough blazing star, button blazing star, lacerate blazing star, tall prairie blazing star, or tall gayfeather) is a perennial wildflower in the Asteraceae family that is found in central to eastern North America in habitats that range from mesic to dry prairie and dry savanna. Description ''Liatris aspera'' is a perennial herb that grows as a single, erect, unbranched stem high. Leaves are numerous on the stem, alternate, and narrowly lanceolate with the lower leaves larger, up to long and wide, becoming smaller and narrower higher on the plant. The inflorescence is an erect raceme with numerous, purple, button-like flower heads, short-stalked or stalkless, blooming from the top down. It flowers from mid-August through October, with seed becoming ripe in October to November. Distribution and habitat This plant is native to the United States from Texas to the west and New York to the east. It is also native to Ontario in Canada. It grows in prairi ...

Pappus (botany)
In Asteraceae, the pappus is the modified calyx, the part of an individual floret, that surrounds the base of the corolla tube in flower. It functions as a wind-dispersal mechanism for the seeds. The term is sometimes used for similar structures in other plant families e.g. in certain genera of the Apocynaceae, although the pappus in Apocynaceae is not derived from the calyx of the flower. In Asteraceae, the pappus may be composed of bristles (sometimes feathery), awns, scales, or may be absent, and in some species, is too small to see without magnification. In genera such as ''Taraxacum'' or ''Eupatorium'', feathery bristles of the pappus function as a "parachute" which enables the seed to be carried by the wind. The name derives from the Ancient Greek word ''pappos'', Latin ''pappus'', meaning "old man", so used for a plant (assumed to be an ''Erigeron'' species) having bristles and also for the woolly, hairy seed of certain plants. The pappus of the dandelion plays a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cypselae
The family Asteraceae, alternatively Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales. Commonly referred to as the aster, daisy, composite, or sunflower family, Compositae were first described in the year 1740. The number of species in Asteraceae is rivaled only by the Orchidaceae, and which is the larger family is unclear as the quantity of extant species in each family is unknown. Most species of Asteraceae are annual, biennial, or perennial herbaceous plants, but there are also shrubs, vines, and trees. The family has a widespread distribution, from subpolar to tropical regions in a wide variety of habitats. Most occur in hot desert and cold or hot semi-desert climates, and they are found on every continent but Antarctica. The primary common characteristic is the existence of sometimes hundreds of tiny individual florets which are held together by protective involucres in flower heads, or more technic ...

Style (botany)
The stigma () is the receptive tip of a carpel, or of several fused carpels, in the gynoecium of a flower. Description The stigma, together with the style and ovary (typically called the stigma-style-ovary system) comprises the pistil, which is part of the gynoecium or female reproductive organ of a plant. The stigma itself forms the distal portion of the style, or stylodia, and is composed of , the cells of which are receptive to pollen. These may be restricted to the apex of the style or, especially in wind pollinated species, cover a wide surface. The stigma receives pollen and it is on the stigma that the pollen grain germinates. Often sticky, the stigma is adapted in various ways to catch and trap pollen with various hairs, flaps, or sculpturings. The pollen may be captured from the air (wind-borne pollen, anemophily), from visiting insects or other animals ( biotic pollination), or in rare cases from surrounding water (hydrophily). Stigma can vary from long and slen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flower Head
A pseudanthium (Greek for "false flower"; ) is an inflorescence that resembles a flower. The word is sometimes used for other structures that are neither a true flower nor a true inflorescence. Examples of pseudanthia include flower heads, composite flowers, or capitula, which are special types of inflorescences in which anything from a small cluster to hundreds or sometimes thousands of flowers are grouped together to form a single flower-like structure. Pseudanthia take various forms. The real flowers (the florets) are generally small and often greatly reduced, but the pseudanthium itself can sometimes be quite large (as in the heads of some varieties of sunflower). Pseudanthia are characteristic of the daisy and sunflower family (Asteraceae), whose flowers are differentiated into ray flowers and disk flowers, unique to this family. The disk flowers in the center of the pseudanthium are actinomorphic and the corolla is fused into a tube. Flowers on the periphery are zygomorp ...
