Lloydieae
The Lloydieae were a tribe of monocotyledon perennial, herbaceous mainly bulbous flowering plants in the Liliaceae (Lily) family. The tribe was generally considered monogeric, being represented by the single genus ''Lloydia''. But since that genus has at various times and is now considered to be part of the genus ''Gagea'', and therefore in the tribe Lilieae, it was sometimes listed with both genera. Furthermore, many authorities place ''Gagea'' into a separate tribe, Tulipeae. It has also historically been considered to be a subtribe of the Lilieae. In 2013, Kim ''et al.'' proposed splitting off ''Gagea'' from the rest of Tulipeae by resurrecting the tribe Lloydieae.

Taxonomy Of Liliaceae
The taxonomy of the plant family Liliaceae has had a complex history since its first description in the mid-eighteenth century. Originally, the Liliaceae were defined as having a " ''calix''" (perianth) of six equal-coloured parts, six stamens, a single style, and a superior, three-chambered (trilocular) ovary turning into a capsule fruit at maturity. The taxonomic circumscription of the family Liliaceae progressively expanded until it became the largest plant family and also extremely diverse, being somewhat arbitrarily defined as all species of plants with six tepals and a superior ovary. It eventually came to encompass about 300 genera and 4,500 species, and was thus a "catch-all" and hence paraphyletic. Only since the more modern taxonomic systems developed by the Angiosperm Phylogeny Group (APG) and based on phylogenetic principles, has it been possible to identify the many separate taxonomic groupings within the original family and redistribute them, leaving a relatively sm ...

Tulipeae
The Tulipeae (syn. Tulipoideae) Duby is a tribe of monocotyledon perennial, herbaceous mainly bulbous flowering plants in the Liliaceae (lily) family. As originally conceived by Duby (1828), "Tulipaceae" was a tribe within Liliaceae, consisting of the genera ''Tulipa'', ''Fritillaria'' and Lilium. Description Herbaceous non-climbing bulbous plants. Bulbs consisting of a single scale. Anthers pseudo-basifixed. fruit consists of a loculicidal capsule, seeds not winged. Tetrasporic embryo-sac formation with 7–8 nuclei. Nucella having a short base. Vesicular-arbuscular mycorrhizae (VAM) non-''Clintonia'' type. Chromosomes large - 2–11 μm (1–6 μm in ''Gagea''). Genome size (3)4–25(70) pg, x = (9)12. Polyploidy common. Taxonomy Tulipeae remained a core group of the Liliaceae, containing the type genus, Lilium for most of its taxonomic history. For instance, Bentham and Hooker (1883), placed ''Lilium'' together with ''Tulipa'' and five other genera in Liliaceae tri ...

Tribe (biology)
In biology, a tribe is a taxonomic rank above genus, but below family (biology), family and subfamily. It is sometimes subdivided into subtribes. By convention, all taxonomic ranks from genus upwards are capitalized, including both tribe and subtribe. In zoology, the standard ending for the name of a zoological tribe is "-ini". Examples include the tribes Goat-antelope#Tribe Caprini, Caprini (goat-antelopes), Hominini (hominins), Bombini (bumblebees), and Thunnini (tunas). The tribe Hominini is divided into subtribes by some scientists; subtribe Hominina then comprises "humans". The standard ending for the name of a zoological subtribe is "-ina". In botany, the standard ending for the name of a botanical tribe is "-eae". Examples include the tribes Acalypheae and Scilloideae#Hyacintheae, Hyacintheae. The tribe Hyacintheae is divided into subtribes, including the subtribe Massoniinae. The standard ending for the name of a botanical subtribe is "-inae". In bacteriology, the form ...

Monocotyledon
Monocotyledons (), commonly referred to as monocots, ( Lilianae ''sensu'' Chase & Reveal) are grass and grass-like flowering plants (angiosperms), the seeds of which typically contain only one embryonic leaf, or cotyledon. They constitute one of the major groups into which the flowering plants have traditionally been divided; the rest of the flowering plants have two cotyledons and are classified as dicotyledons, or dicots. Monocotyledons have almost always been recognized as a group, but with various taxonomic ranks and under several different names. The APG III system of 2009 recognises a clade called "monocots" but does not assign it to a taxonomic rank. The monocotyledons include about 60,000 species, about a quarter of all angiosperms. The largest family in this group (and in the flowering plants as a whole) by number of species are the orchids (family Orchidaceae), with more than 20,000 species. About half as many species belong to the true grasses ( Poaceae), which are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perennial
A perennial plant or simply perennial is a plant that lives more than two years. The term ('' per-'' + '' -ennial'', "through the years") is often used to differentiate a plant from shorter-lived annuals and biennials. The term is also widely used to distinguish plants with little or no woody growth (secondary growth in girth) from trees and shrubs, which are also technically perennials. Perennialsespecially small flowering plantsthat grow and bloom over the spring and summer, die back every autumn and winter, and then return in the spring from their rootstock or other overwintering structure, are known as herbaceous perennials. However, depending on the rigours of local climate (temperature, moisture, organic content in the soil, microorganisms), a plant that is a perennial in its native habitat, or in a milder garden, may be treated by a gardener as an annual and planted out every year, from seed, from cuttings, or from divisions. Tomato vines, for example, live several ye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Herbaceous
Herbaceous plants are vascular plants that have no persistent woody stems above ground. This broad category of plants includes many perennials, and nearly all annuals and biennials. Definitions of "herb" and "herbaceous" The fourth edition of the '' Shorter Oxford English Dictionary'' defines "herb" as: #"A plant whose stem does not become woody and persistent (as in a tree or shrub) but remains soft and succulent, and dies (completely or down to the root) after flowering"; #"A (freq. aromatic) plant used for flavouring or scent, in medicine, etc.". (See: Herb) The same dictionary defines "herbaceous" as: #"Of the nature of a herb; esp. not forming a woody stem but dying down to the root each year"; #"BOTANY Resembling a leaf in colour or texture. Opp. scarious". Botanical sources differ from each other on the definition of "herb". For instance, the Hunt Institute for Botanical Documentation includes the condition "when persisting over more than one growing season, the p ...

Bulbous
In botany, a bulb is structurally a short stem with fleshy leaves or leaf basesBell, A.D. 1997. ''Plant form: an illustrated guide to flowering plant morphology''. Oxford University Press, Oxford, U.K. that function as food storage organs during dormancy. (In gardening, plants with other kinds of storage organ are also called "ornamental bulbous plants" or just "bulbs".) Description The bulb's leaf bases, also known as scales, generally do not support leaves, but contain food reserves to enable the plant to survive adverse conditions. At the center of the bulb is a vegetative growing point or an unexpanded flowering shoot. The base is formed by a reduced stem, and plant growth occurs from this basal plate. Roots emerge from the underside of the base, and new stems and leaves from the upper side. Tunicate bulbs have dry, membranous outer scales that protect the continuous lamina of fleshy scales.

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. They include all forbs (flowering plants without a woody stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. The term "angiosperm" is derived from the Greek words ἀγγεῖον / ('container, vessel') and σπέρμα / ('seed'), meaning that the seeds are enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Angiosperms are distinguished from the other seed-producing plants, the gymnosperms, by having flowers, xylem consisting of vessel elements instead of tracheids, endosperm within their seeds, and fruits that completely envelop the seeds. The ancestors of flowering plants diverged from the common ance ... [...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 s ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opi ...

Gagea
''Gagea'' is a large genus of spring flowers in the lily family. It is found primarily in Eurasia with a few species extending into North Africa and one species ('' Gagea serotina'') in North America. The genus is named after the English naturalist Sir Thomas Gage (1791-1820). They were originally described as species of ''Ornithogalum'', which, together with the usual yellow colour of the flowers, explains the English name yellow star-of-Bethlehem for the common European species, '' Gagea lutea''. p. 25. Species , the World Checklist of Selected Plant Families The World Checklist of Selected Plant Families (usually abbreviated to WCSP) is an "international collaborative programme that provides the latest peer reviewed and published opinions on the accepted scientific names and synonyms of selected pl ... recognizes over 200 species, including those previously assigned to ''Lloydia''.

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] |
