Helichrysum
The genus ''Helichrysum'' consists of an estimated 600 species of flowering plants in the sunflower family (Asteraceae). The type species is '' Helichrysum orientale''. They often go by the names everlasting, immortelle, and strawflower. The name is derived from the Ancient Greek words (helios, sun) and (, gold). It occurs in Africa (with 244 species in South Africa), Madagascar, Australasia and Eurasia. The plants may be annuals, herbaceous perennials or shrubs, growing to a height of . The genus was a wastebasket taxon, and many of its members have been reclassified in smaller genera, most notably the Everlastings, now in the genus '' Xerochrysum''. Their leaves are oblong to lanceolate. They are flat and pubescent on both sides. The bristles of the pappus are scabrous, barbellate, or plumose. The receptacle (''base of the flower head'') is often smooth, with a fringed margin, or honey-combed, and resemble daisies. They may be in almost all colors, except blue. There are ...

Chrysocephalum Semipapposum
''Chrysocephalum semipapposum'', commonly known as clustered everlasting is a perennial shrub native to Australia. Clustered everlasting belongs to the family Asteraceae. ''C. semipapposum'' produces terminal flowers heads in clusters, mainly between spring and early summer with silver-grey appearing stems and branches. It grows up to 40 cm high and 60 cm high, although there have been some varieties which can grow up to 1 m. ''C. semipapposum'' is often confused with ''Chrysocephalum apiculatum'' or 'yellow buttons', due to their similar appearances. ''C. semipapposum'' has 4 different subspecies, however they lack distinctive qualities and are often hard to identify. ''C. semipapposum'' is endemic to Australia and can be found in multiple states, most notably within Victoria. The plant is found in a variety of habitats including dry rocky regions. Clustered everlasting often grows sparsely and is rarely found in abundance and can be mistaken for a weed. Clustered ever ...

Helichrysum Orientale
''Helichrysum orientale'', also known as everlasting and immortelle, is the type species for the genus ''Helichrysum''. It is a native of North Africa, Crete, and parts of Asia bordering on the Mediterranean. It is cultivated in many parts of Europe. It first became known in Europe about the year 1629, and has been cultivated since 1815. Description In common with several other plants of the genus ''Helichrysum'', the immortelle plant possesses a large involucre of dry scale-like or scarious bracts, which preserve their appearance when dried, provided the plant be gathered in proper condition. The colour of the bracts is a deep yellow. The evergreen, downy, gray ash foliage becomes almost white in summer, making ''Helichrysum orientale'' an attractive plant for gardening. Sources The chief supplies of ''Helichrysum orientale'' come from lower Provence, where it is cultivated in large quantities on the ground sloping to the Mediterranean, in positions well exposed to the sun, an ...

Chrysocephalum Apiculatum
''Chrysocephalum apiculatum'', known by the common names common everlasting and yellow buttons, is a perennial herb native to southern Australia. It is a member of the Asteraceae, the daisy family. The name "everlasting" was inspired by its use as a long-lasting cut flower. It is increasing in popularity in Australia as a cottage garden plant, but is still not well known. Description The common everlasting grows to around 40 centimeters high, with spreading horizontal stems that turn upwards as they get longer. The elongated silvery grey leaves clasp tightly to the stems and are covered in fine, silky hairs. The flower heads are yellow in color and spherical in shape, around 1 centimeter in diameter each, and often borne in clusters. The florets are minute. Like many daisies, it has seeds which are gradually dispersed on the wind. The seed germinates readily, but has a short viable life. Habitat The plant grows in full sun on light, well-drained soil in grassy areas. It can toler ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Asteraceae
Asteraceae () is a large family (biology), family of flowering plants that consists of over 32,000 known species in over 1,900 genera within the Order (biology), order Asterales. 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 taxon, extant species in each family is unknown. The Asteraceae were first described in the year 1740 and given the original name Composita, Compositae. The family is commonly known as the aster, Daisy (flower), daisy, composite, or sunflower family. Most species of Asteraceae are herbaceous plants, and may be Annual plant, annual, Biennial plant, biennial, or Perennial plant, perennial, 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 climate, hot desert and cold or hot Semi-arid climate, semi-desert climates, and they are found on ever ...

Polymorphism (biology)
In biology, polymorphism is the occurrence of two or more clearly different morphs or forms, also referred to as alternative '' phenotypes'', in the population of a species. To be classified as such, morphs must occupy the same habitat at the same time and belong to a panmictic population (one with random mating). Ford E.B. 1965. ''Genetic polymorphism''. Faber & Faber, London. Put simply, polymorphism is when there are two or more possibilities of a trait on a gene. For example, there is more than one possible trait in terms of a jaguar's skin colouring; they can be light morph or dark morph. Due to having more than one possible variation for this gene, it is termed 'polymorphism'. However, if the jaguar has only one possible trait for that gene, it would be termed "monomorphic". For example, if there was only one possible skin colour that a jaguar could have, it would be termed monomorphic. The term polyphenism can be used to clarify that the different forms arise from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polyphyletic
A polyphyletic group is an assemblage that includes organisms with mixed evolutionary origin but does not include their most recent common ancestor. The term is often applied to groups that share similar features known as Homoplasy, homoplasies, which are explained as a result of convergent evolution. The arrangement of the members of a polyphyletic group is called a polyphyly .. [Source for pronunciation.] It is contrasted with monophyly and paraphyly. For example, the biological characteristic of warm-bloodedness evolved separately in the ancestors of mammals and the ancestors of birds; "warm-blooded animals" is therefore a polyphyletic grouping. Other examples of polyphyletic groups are algae, C4 photosynthesis, C4 photosynthetic plants, and Xenarthra#Evolutionary relationships, edentates. Many taxonomists aim to avoid homoplasies in grouping taxa together, with a goal to identify and eliminate groups that are found to be polyphyletic. This is often the stimulus for major re ...

Philip Miller
Philip Miller Royal Society, FRS (1691 – 18 December 1771) was an English botany, botanist and gardener of Scottish descent. Miller was chief gardener at the Chelsea Physic Garden for nearly 50 years from 1722, and wrote the highly popular ''The Gardeners Dictionary''. Life Born in Deptford or Greenwich, Miller was chief gardener at the Chelsea Physic Garden from 1722 until he was pressured to retire shortly before his death. According to the botanist Peter Collinson (botanist), Peter Collinson, who visited the physic garden in July 1764 and recorded his observation in his commonplace books, Miller "has raised the reputation of the Chelsea Garden so much that it excels all the gardens of Europe for its amazing variety of plants of all orders and classes and from all climates..." He wrote ''The Gardener's and Florists Dictionary or a Complete System of Horticulture'' (1724) and The Gardeners Dictionary, ''The Gardener's Dictionary containing the Methods of Cultivating and Im ...
