Eriophyllum
''Eriophyllum'', commonly known as the woolly sunflower, is a North American genus of plants in the family Asteraceae. The genus is native to western North America (USA, Canada, northwestern Mexico), with a concentration of narrow endemics in California. ''Eriophyllum'' species are used as food plants by the larvae of some Lepidoptera species including ''Phymatopus californicus''. Description ''Eriophyllum'' is an annual or perennial shrub or subshrub, some species growing to a height of 200 cm (6.7 feet). Leaves present generally alternate and entire to nearly compound, with woolly hairs on some of the species. The inflorescence contains numerous yellow flower heads in flat-topped clusters. The involucre structure is obconic to hemispheric. Phyllaries are either free or more or less fused; the receptacle presents typically flat, but naked. The ray flowers are present in some species but not in others. Fruit In botany, a fruit is the seed-bearing structure in flo ...

Eriophyllum Lanatum
''Eriophyllum lanatum'', with the common names common woolly sunflower, Oregon sunshine and golden yarrow, is a common, widespread, North American plant in the family Asteraceae.Sierra Nevada Wildflowers, Karen Wiese, 2nd Ed. 2013, p. 116 Description ''Eriophyllum lanatum'' is a perennial herb growing from in height, in well-branched clumps. Both the stems and leaves may be covered with a woolly gray hair, but some plants lack this. The leaves are long, linear on the upper stems, and slender and pinnately lobed on the lower stems. The hairs conserve water by reflecting heat and reducing air movement across the leaf's surface. The flowers are yellow and composite, looking much like true sunflowers, and sometimes grow to about wide. Both the (8–12) ray and disk flowers are yellow, with one flower head on each flowering stalk. The flower heads have 6–14 rays, which are darker towards the base, and several disk flowers. They bloom from May to August. The seeds have scales at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Phymatopus
''Phymatopus'' (originally: ''Noctua'' Linnaeus, 1758) is a genus of moths of the family Hepialidae (commonly referred to as swift moths or ghost moths), which consists of around 500 species and 30 genera. The genus was erected by Hans Daniel Johan Wallengren in 1869. They can be found across Eurasia and North America. Species can be distinguished by the different morphology of male genitalia and different forewing patterns, which vary in stripe colour and size and arrangement of spots. The stripes themselves consist of spots separated by dark veins which are fringed by thin black lines from both inner and outer sides.

North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.

Ray Flowers
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 technically ...
