Lilioideae
The Lilioideae are a subfamily of monocotyledonous perennial, herbaceous mainly bulbous flowering plants in the lily family, Liliaceae. They are found predominantly in the temperate and colder regions of the Northern Hemisphere, particularly East Asia and North America. The subfamily includes two tribes. They are of economic importance, particularly the lilies and tulips. Description Lilioideae genera are relatively homogeneous and distinct from the other two Liliaceae subfamilies (Calochortoideae and Streptopoideae). They are perennial herbaceous flowering plants that are mainly bulbous (Lilieae) with contractile roots, but may be rhizomatous (Medeoleae). Stems unbranched, leaves with parallel venation. Flowers are large and showy. The embryo sac (megagametophyte) is of the Fritillaria-type (tetrasporic). Capsule septicidal, seeds often flattened, exotesta palisaded or lignified. The seeds of Medeoleae are striate. Chromosome number may be 7 (Medeoleae), 9, or 11–14, with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liliaceae
The lily family, Liliaceae, consists of about 15 genera and 610 species of flowering plants within the order Liliales. They are monocotyledonous, perennial, herbaceous, often bulbous geophytes. Plants in this family have evolved with a fair amount of morphological diversity despite genetic similarity. Common characteristics include large flowers with parts arranged in threes: with six colored or patterned petaloid tepals (undifferentiated petals and sepals) arranged in two whorls, six stamens and a superior ovary. The leaves are linear in shape, with their veins usually arranged parallel to the edges, single and arranged alternating on the stem, or in a rosette at the base. Most species are grown from bulbs, although some have rhizomes. First described in 1789, the lily family became a paraphyletic "catch-all" (wastebasket) group of lilioid monocots that did not fit into other families and included a great number of genera now included in other families and in some cases in ...

Lilieae
The Lilieae are a monophyletic tribe of monocotyledon perennial, herbaceous mainly bulbous flowering plants in the lily family (Liliaceae). Taxonomy The term has varied over the years but in modern classification constitutes either a broad circumscription (Lilieae ''sensu lato'', ''s.l.'') with eight genera, placed in the subfamily Lilioideae, or narrower circumscription with six genera (Lilieae ''sensu stricto'', ''s.s.''), excluding ''Tulipa'' (which now includes '' Amana'') and ''Erythronium'' which are treated as a separate tribe, Tulipeae. Within Lilieae ''s.s.'', ''Gagea'' now includes '' Lloydia'', and ''Lilium'' includes ''Nomocharis'', reducing the number of genera to four, with about 260–300 species. Phylogeny The evolutionary and phylogenetic relationships between the genera currently included in Liliaceae are shown in this cladogram. Distribution and habitat Lilieae ''s.s.'' are distributed in temperate Northern Hemisphere areas, with the main centre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Notholirion
''Notholirion'' is a small Asian genus of bulbous plants in the lily family, Liliaceae. It is closely related to Lilium, but each individual flowers only once, and then dies after producing offsets. The bulb is covered by a tunic. Leaves are basal, produced in autumn and winter. Taxonomy Baker (1874) considered ''Notholirion'' to be a subgenus of ''Fritillaria'', but Boissier (1884) separated it as a distinct genus. The evolutionary and phylogenetic relationships between the genera currently included in Liliaceae are shown in the following Cladogram: Species List of species: * '' Notholirion bulbiferum'' (Lingelsh.) Stearn - Nepal, Bhutan, Sikkim, Assam, Myanmar, Gansu, Shaanxi, Sichuan, Tibet, Yunnan * '' Notholirion koeiei'' Rech.f. - Iran + Iraq * '' Notholirion macrophyllum'' (D.Don) Boiss. - Tibet, Nepal, Sichuan, Yunnan, Bhutan, and Sikkim * ''Notholirion thomsonianum'' (Royle) Stapf - Afghanistan, Himalayas of northern Pakistan + northern India India, of ...

Medeoleae
The Medeoloideae (syn. Medeoleae) are a subfamily of monocotyledon perennial, herbaceous mainly bulbous flowering plants in the lily family, Liliaceae. Description The Medeoleae are characterised by rhizomatous stems, inconspicuous flowers, the formation of berries that are animal dispersed and broad reticulate-veined leaves. Taxonomy In the most recent taxonomy of the AP Web system, this subfamily has been downgraded to a tribe, Medeoleae, within the subfamily Lilioideae. The taxon In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit.

Medeola
''Medeola virginiana'', known as Indian cucumber, cucumber root, or Indian cucumber-root, is an eastern North American plant species in the lily family, Liliaceae. It is the only currently recognized plant species in the genus ''Medeola''. It grows in the understory of forests. The plant bears edible rhizomes that have a mild cucumber-like flavor. Description ''Medeola virginiana'' shoots consist of two tiers of whorled leaves. The lower tier typically bears between five and nine (occasionally up to 12) lance shaped leaves. The upper tier bears three to five ovate leaves. The leaves have an entire (smooth) margin. Some individuals lack a second tier of whorled leaves. The second tier is produced when the plant flowers. When two-tiered, plants grow to high. The flowers have yellowish green tepals and appear in late spring. The fruit is a dark blue to purple, inedible berry above the top tier of leaves. Indian cucumber-root shoots arise each spring from an overwintering tuberlike ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tulips
Tulips (''Tulipa'') are a genus of spring-blooming perennial herbaceous bulbiferous geophytes (having bulbs as storage organs). The flowers are usually large, showy and brightly coloured, generally red, pink, yellow, or white (usually in warm colours). They often have a different coloured blotch at the base of the tepals (petals and sepals, collectively), internally. Because of a degree of variability within the populations, and a long history of cultivation, classification has been complex and controversial. The tulip is a member of the lily family, Liliaceae, along with 14 other genera, where it is most closely related to '' Amana'', ''Erythronium'' and ''Gagea'' in the tribe Lilieae. There are about 75 species, and these are divided among four subgenera. The name "tulip" is thought to be derived from a Persian word for turban, which it may have been thought to resemble by those who discovered it. Tulips originally were found in a band stretching from Southern Europe to Cent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fritillaria
''Fritillaria'' (fritillaries) is a genus of spring flowering herbaceous bulbous perennial plants in the lily family (Liliaceae). The type species, ''Fritillaria meleagris'', was first described in Europe in 1571, while other species from the Middle East and Asia were also introduced to Europe at that time. The genus has about 130–140 species divided among eight subgenera. The flowers are usually solitary, nodding and bell-shaped with bulbs that have fleshy scales, resembling those of lilies. They are known for their large genome size and genetically are very closely related to lilies. They are native to the temperate regions of the Northern hemisphere, from the Mediterranean and North Africa through Eurasia and southwest Asia to western North America. Many are endangered due to enthusiastic picking. The name ''Fritillaria'' is thought to refer to the checkered pattern of ''F. meleagris'', resembling a box in which dice were carried. Fritillaries are commercially important ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Temperate Zone
In geography, the temperate climates of Earth occur in the middle latitudes (23.5° to 66.5° N/S of Equator), which span between the tropics and the polar regions of Earth. These zones generally have wider temperature ranges throughout the year and more distinct seasonal changes compared to tropical climates, where such variations are often small and usually only have precipitation changes. In temperate climates, not only do latitudinal positions influence temperature changes, but sea currents, prevailing wind direction, continentality (how large a landmass is) and altitude also shape temperate climates. The Köppen climate classification defines a climate as "temperate" C, when the mean temperature is above but below in the coldest month to account for the persistency of frost. However, other climate classifications set the minimum at . Zones and climates The north temperate zone extends from the Tropic of Cancer (approximately 23.5° north latitude) to the Arctic ...

Northern Hemisphere
The Northern Hemisphere is the half of Earth that is north of the Equator. For other planets in the Solar System, north is defined as being in the same celestial hemisphere relative to the invariable plane of the solar system as Earth's North Pole. Owing to Earth's axial tilt of 23.439281°, winter in the Northern Hemisphere lasts from the December solstice (typically December 21 UTC) to the March equinox (typically March 20 UTC), while summer lasts from the June solstice through to the September equinox (typically on 23 September UTC). The dates vary each year due to the difference between the calendar year and the astronomical year. Within the Northern Hemisphere, oceanic currents can change the weather patterns that affect many factors within the north coast. Such events include El Niño–Southern Oscillation. Trade winds blow from east to west just above the equator. The winds pull surface water with them, creating currents, which flow westward due to the Coriolis e ...

East Asia
East Asia is the eastern region of Asia, which is defined in both geographical and ethno-cultural terms. The modern states of East Asia include China, Japan, Mongolia, North Korea, South Korea, and Taiwan. China, North Korea, South Korea and Taiwan are all unrecognised by at least one other East Asian state due to severe ongoing political tensions in the region, specifically the division of Korea and the political status of Taiwan. Hong Kong and Macau, two small coastal quasi-dependent territories located in the south of China, are officially highly autonomous but are under Chinese sovereignty. Japan, Taiwan, South Korea, Mainland China, Hong Kong, and Macau are among the world's largest and most prosperous economies. East Asia borders Siberia and the Russian Far East to the north, Southeast Asia to the south, South Asia to the southwest, and Central Asia to the west. To the east is the Pacific Ocean and to the southeast is Micronesia (a Pacific Ocean island group, classifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
