Monocotyledon Reproduction
The monocots (or Monocotyledons) are one of the two major groups of flowering plants (or Angiosperms), the other being the dicots (or dicotyledons). In order to reproduce they utilize various strategies such as employing forms of asexual reproduction, restricting which individuals they are sexually compatible with, or influencing how they are pollinated. Nearly all reproductive strategies that evolved in the dicots have independently evolved in monocots as well. Despite these similarities and their close relatedness, monocots and dicots have distinct traits in their reproductive biologies. Most monocots reproduce sexually through use of seeds that have a single cotyledon, however a great number of monocots reproduce asexually through clonal propagation. Breeding systems that utilize self-incompatibility are much more common than those that utilize self-compatibility. The majority of monocots are animal pollinated (zoophilous), of which most are pollinator generalists. Monocots ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Allium Moly Fax02
''Allium'' is a genus of monocotyledonous flowering plants that includes hundreds of species, including the cultivated onion, garlic, scallion, shallot, leek, and chives. The generic name ''Allium'' is the Latin word for garlic,Gledhill, David (2008). "The Names of Plants". Cambridge University Press. (hardback), (paperback). pp 43 and the type species for the genus is '' Allium sativum'' which means "cultivated garlic".''Allium'' In: Index Nominum Genericorum. In: Regnum Vegetabile (see ''External links'' below). Carl Linnaeus first described the genus ''Allium'' in 1753. Some sources refer to Greek ἀλέω (aleo, to avoid) by reason of the smell of garlic. Various ''Allium'' have been cultivated from the earliest times, and about a dozen species are economically important as crops, or garden vegetables, and an increasing number of species are important as ornamental plants. The decision to include a species in the genus ''Allium'' is taxonomically difficult, and spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
A Closeup Of Turmeric
A, or a, is the first letter and the first vowel of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''a'' (pronounced ), plural ''aes''. It is similar in shape to the Ancient Greek letter alpha, from which it derives. The uppercase version consists of the two slanting sides of a triangle, crossed in the middle by a horizontal bar. The lowercase version can be written in two forms: the double-storey a and single-storey ɑ. The latter is commonly used in handwriting and fonts based on it, especially fonts intended to be read by children, and is also found in italic type. In English grammar, " a", and its variant " an", are indefinite articles. History The earliest certain ancestor of "A" is aleph (also written 'aleph), the first letter of the Phoenician alphabet, which consisted entirely of consonants (for that reason, it is also called an abjad to distinguish it f ...

Musaceae
Musaceae is a family of flowering plants composed of three genera with about 91 known species, placed in the order Zingiberales. The family is native to the tropics of Africa and Asia. The plants have a large herbaceous growth habit with leaves with overlapping basal sheaths that form a pseudostem making some members appear to be woody trees. In most treatments, the family has three genera, '' Musella'', ''Musa'' and ''Ensete''. Cultivated bananas are commercially important members of the family, and many others are grown as ornamental plants. Taxonomy The family has been practically universally recognized by taxonomists, although with differing circumscriptions. Older circumscriptions of the family commonly included the genera now included in Heliconiaceae and Strelitziaceae. The APG III system, of 2009 (unchanged from the APG system, 1998), assigns Musaceae to the order Zingiberales in the clade commelinids in the monocots. Genera As currently circumscribed the family in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyperaceae
The Cyperaceae are a family of graminoid (grass-like), monocotyledonous flowering plants known as sedges. The family is large, with some 5,500 known species described in about 90 genera, the largest being the "true sedges" genus ''Carex'' with over 2,000 species. These species are widely distributed, with the centers of diversity for the group occurring in tropical Asia and tropical South America. While sedges may be found growing in almost all environments, many are associated with wetlands, or with poor soils. Ecological communities dominated by sedges are known as sedgelands or sedge meadows. Some species superficially resemble the closely related rushes and the more distantly related grasses. Features distinguishing members of the sedge family from grasses or rushes are stems with triangular cross-sections (with occasional exceptions, a notable example being the tule which has a round cross-section) and leaves that are spirally arranged in three ranks. In comparison, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colchicaceae
Colchicaceae is a family of flowering plants that includes 15 genera with a total of about 285 known species according to Christenhusz and Byng in 2016. Description The family is characterized by the presence of colchicine. Taxonomy The APG III system, of 2009 (unchanged from the APG systems, of 1998 and 2003), recognizes this family and places it in the order Liliales, in the clade monocots. It is a group of herbaceous perennials with rhizomes or corms. The Dahlgren system and the Thorne system (1992) also recognized this family, and placed it in order Liliales in superorder Lilianae in subclass Liliidae (monocotyledons) of class Magnoliopsida (angiosperms). Genera The following is an alphabetic list of genera usually included in this family : The phylogenetic classification of Vinnersten & Manning circumscribes the family as follows: * tribe Burchardieae ** ''Burchardia'' R.Br. * tribe Uvularieae ** ''Disporum'' Salisb.

Alismataceae
The water-plantains (Alismataceae) are a family of flowering plants, comprising 19 genera (17 extant and 2 fossil) and 117 species. The family has a cosmopolitan distribution, with the greatest number of species in temperate regions of the Northern Hemisphere. Most of the species are Herbaceous plant, herbaceous aquatic plants growing in marshes and ponds. Description Most Alismataceae are robust Perennial plant, perennials, but some may be Annual plant, annual or perennial, depending on water conditions — they are normally perennial in permanent waters, annual in more seasonal conditions but there are exceptions. The Plant stem, stems are corm-like or stoloniferous. Juvenile and submerse Leaf, leaves are often Leaf shape, linear, whilst more mature and emerse leaves can be linear to Leaf shape, ovate or even Leaf shape, sagittate. Most have a distinct Petiole (botany), petiole, with a sheathed base. The inflorescence is usually compound with whorls of branches, though som ...

Araceae
The Araceae are a family of monocotyledonous flowering plants in which flowers are borne on a type of inflorescence called a spadix. The spadix is usually accompanied by, and sometimes partially enclosed in, a spathe (or leaf-like bract). Also known as the arum family, members are often colloquially known as aroids. This family of 140 genera and about 4,075 known species is most diverse in the New World tropics, although also distributed in the Old World tropics and northern temperate regions. Many species display very decorative leaves and flowers, and they are widely used for gardening; popular as indoor plants and also outdoor plants where climates are mild, and winter freezes will not generally occur. However, some temperate species are also very popular in Mediterranean-climate gardening, or in moderately cool temperate zones, such as ''Zantedeschia''. Description Species within Araceae are often rhizomatous or tuberous, and the leaves nearly always contain calcium oxa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asparagaceae
Asparagaceae, known as the asparagus family, is a family of flowering plants, placed in the order Asparagales of the monocots. The family name is based on the edible garden asparagus, ''Asparagus officinalis''. Those who live in the temperate climates may be surprised to learn that this family includes both common garden plants as well as common houseplants. The garden plants include asparagus, yucca, bluebell, and hosta, and the houseplants include snake plant, corn cane, spider plant and plumosus fern. Taxonomy In earlier classification systems, the species involved were often treated as belonging to the family Liliaceae. The APG II system of 2003 allowed two options as to the circumscription of the family: either Asparagaceae ''sensu lato'' ("in the wider sense") combining seven previously recognized families, or Asparagaceae ''sensu stricto'' ("in the strict sense") consisting of very few genera (notably ''Asparagus'', also ''Hemiphylacus''), but nevertheless totalling ...

Nelumbonaceae
Nelumbonaceae is a family of aquatic flowering plants. ''Nelumbo'' is the sole extant genus, containing ''Nelumbo lutea'', native to North America, and ''Nelumbo nucifera'', widespread in Asia. At least four other genera, ''Nelumbites'', ''Exnelumbites'', ''Paleonelumbo'', and ''Nelumbago'', are known from fossils. Nelumbonaceae were once included in the waterlily family, Nymphaeaceae. Genetic analysis determined that the similarities between the families are an example of convergent evolution. Nelumbonaceae are highly modified eudicots belonging to the order Proteales, their closest living relatives being the plane trees (Platanaceae) and Proteaceae.Stevens, P.F. (2001 onwards),Proteales: Nelumbonaceae, ''Angiosperm Phylogeny Website'', retrieved 2014-02-25 The APG IV system of 2016 places the family in the order Proteales, in the clade eudicots. The Cronquist system, of 1981, also recognized this family, but placed it in order Nymphaeales in subclass Magnoliidae in class M ...

Zingiberaceae
Zingiberaceae () or the ginger family is a family of flowering plants made up of about 50 genera with a total of about 1600 known species of aromatic perennial herbs with creeping horizontal or tuberous rhizomes distributed throughout tropical Africa, Asia, and the Americas. Many of the family's species are important ornamental, spice, or medicinal plants. Ornamental genera include the shell gingers ('' Alpinia''), Siam or summer tulip ('' Curcuma alismatifolia''), '' Globba'', ginger lily ('' Hedychium''), '' Kaempferia'', torch-ginger '' Etlingera elatior'', ''Renealmia'', and ginger (''Zingiber''). Spices include ginger (''Zingiber''), galangal or Thai ginger ('' Alpinia galanga'' and others), melegueta pepper (''Aframomum melegueta''), myoga (''Zingiber mioga''), korarima (''Aframomum corrorima''), turmeric (''Curcuma''), and cardamom ('' Amomum'', '' Elettaria'').

Poaceae
Poaceae () or Gramineae () is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos and the grasses of natural grassland and species cultivated in lawns and pasture. The latter are commonly referred to collectively as grass. With around 780 genera and around 12,000 species, the Poaceae is the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae. The Poaceae are the most economically important plant family, providing staple foods from domesticated cereal crops such as maize, wheat, rice, barley, and millet as well as feed for meat-producing animals. They provide, through direct human consumption, just over one-half (51%) of all dietary energy; rice provides 20%, wheat supplies 20%, maize (corn) 5.5%, and other grains 6%. Some members of the Poaceae are used as building materials (bamboo, thatch, and straw); others can provide a source of biofuel, ...

Amaryllidaceae
The Amaryllidaceae are a family of herbaceous, mainly perennial and bulbous (rarely rhizomatous) flowering plants in the monocot order Asparagales. The family takes its name from the genus ''Amaryllis'' and is commonly known as the amaryllis family. The leaves are usually linear, and the flowers are usually bisexual and symmetrical, arranged in umbels on the stem. The petals and sepals are undifferentiated as tepals, which may be fused at the base into a floral tube. Some also display a corona. Allyl sulfide compounds produce the characteristic odour of the onion subfamily (Allioideae). The family, which was originally created in 1805, now contains about 1600 species, divided into about 70–75 genera, 17 tribes and three subfamilies, the Agapanthoideae (agapanthus), Allioideae (onions and chives) and Amaryllidoideae (amaryllis, daffodils, snowdrops). Over time, it has seen much reorganisation and at various times was combined with the related Liliaceae. Since 2009, a very broa ...
