The genus Helichrysum consists of an estimated 600 species, in the sunflower family (Asteraceae). Plants are living Organisms belonging to the kingdom Plantae. The flowering plants or angiosperms ( Angiospermae or Magnoliophyta) are the most widespread group Magnoliopsida is the Botanical name for a class of Flowering plants By definition the class will include the family Magnoliaceae, but its The Asterales are an order of Dicotyledonous Flowering plants which include the composite family Asteraceae ( Sunflowers daisies The family Asteraceae or Compositae (known as the aster, daisy, or sunflower family) is the largest family of Flowering Asteroideae is a Subfamily of the Plant family Asteraceae. It is made of several Tribes including Astereae, Calenduleae Gnaphalieae is a tribe of flowering plants in the family Asteraceae. Philip Miller ( 1691 - 18 December 1771) was a botanist of Scottish descent Year 1754 ( MDCCLIV) was a Common year starting on Tuesday (link will display the full calendar of the Gregorian calendar (or Helichrysum arenarium is also known as dwarf everlast. It grows to be an average of 0 Helichrysum italicum is a Flowering plant of the daisy family Asteraceae. Helichrysum petiolare, known as limelight, and Impepho or Imphepho when dried is a plant in the genus Helichrysum. The red everlasting is a flowering plant of the genus Helichrysum in the daisy family ( Asteraceae) The family Asteraceae or Compositae (known as the aster, daisy, or sunflower family) is the largest family of Flowering The type species is Helichrysum orientale.

The name is derived from the Greek words helisso (to turn around) and chrysos (gold). Common names include strawflower and everlasting.

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 60-90 cm. Botanically an annual plant is a Plant that usually germinates, Flowers and dies in one Year. A perennial plant or perennial ( Latin per, "through" annus, "year" is a Plant that lives for more than A shrub or Bush is a horticultural rather than strictly botanical category of Woody plant, distinguished from a Tree

Their leaves are oblong to lanceolate. In Botany, a leaf is an above-ground Plant organ specialized for Photosynthesis. 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 many capitula and generally flat-topped corymbs or panicles. An inflorescence is a group or cluster of Flowers arranged on a stem that is composed of a main Branch or a complicated arrangement of branches A panicle is a compound Raceme, a loose much-branched indeterminate Inflorescence with pedicellate Flowers (and Fruit A panicle is a compound Raceme, a loose much-branched indeterminate Inflorescence with pedicellate Flowers (and Fruit The corolla lobes show glandular hairs at the abaxial surface. A petal (from Ancient Greek petalon "leaf" "thin plate" regarded as a highly modified leaf is one member or part of the corolla

Several species are grown as ornamental plants, and for dried flowers. Ornamental plants are typically grown in the flower Garden or as House plants Most commonly they are grown for the display of their Flowers Other common When cut young and dried, the open flowers and stalks preserve their colour and shape for long periods.

Helichrysum species are used as food plants by the larvae of some Lepidoptera species including the bucculaticid leaf-miners Bucculatrix gnaphaliella (which feeds exclusively on Helichrysum arenarium) and Bucculatrix helichrysella (feeds exclusively on H. A larva ( Latin; plural larvae) is a juvenile form of Animal with indirect development, undergoing Metamorphosis (for example Lepidoptera is an order of Insect that includes Moths and butterflies. Bucculatricidae or ( Bucculatrigidae) is a family of Moths This small family has representatives in all parts of the world italicum) and the Coleophora case-bearers C. Coleophora is a very large genus of Moths of the family Coleophoridae with around 1000 described species caelebipennella, C. gnaphalii (feeds exclusively on H arenarium) and C. helichrysiella (feeds exclusively on H. italicum).

Species

Hilllard (1983) divided this large and heterogeneous genus in 30 morphological groups. But this genus is controversial and is considered by many as an artificial genus. The taxonomy of the large polymorphic and probably polyphyletic Helichrysum genus is complex and not yet satisfactorily resolved. Polymorphism in biology occurs when two or more clearly different Phenotypes exist in the same population of a species — in other words the occurrence of more than one In Phylogenetics, a Taxon is polyphyletic ( Greek for "of many races" if the trait its members have in common evolved separately in different Several Australian species, such as H. acuminatum and H. bracteatum, have been reclassified in the genus Xerochrysum in 1991, resp. Xerochrysum ( syn Bracteantha) is a Genus of six species of Flowering plants native to southern and eastern Australia as X. subundulatum and X. bracteatum. In 1989, misaligned species of Helichrysum were reclassified in Syncarpha. Syncarpha ( Everlasting) is a Genus of Herbaceous Flowering plants in the daisy family Asteraceae. Species included in Pseudognaphalium are probably congeneric with Helichrysum. In 2004, A. Miller identified five potentially new species that have not yet been published but were included in the IUCN Red List data, given their restricted range in Yemen. The IUCN Red List of Threatened Species (also known as the IUCN Red List or Red Data List) created in 1963 is the world's most comprehensive inventory of the global Yemen ( Arabic: اليَمَن al-Yaman officially the Republic of Yemen ( Arabic: الجمهورية اليمنية al-Jumhuuriyya They are as follows:
