Asparagus
Asparagus (''Asparagus officinalis'') is a perennial flowering plant species in the genus ''Asparagus (genus), Asparagus'' native to Eurasia. Widely cultivated as a vegetable crop, its young shoots are used as a spring vegetable. Description Asparagus is an herbaceous, perennial plant growing typically to tall, with stout stems with much-branched, feathery foliage. It has been known to grow as long as . The 'leaves' are needle-like cladodes (Aerial stem modification, modified stems) in the Leaf#Morphology, axils of scale leaves; they are long and broad, and clustered in fours, up to 15, together, in a rose-like shape. The root system, often referred to as a 'crown', is adventitious; the root type is Fascicle (botany), fasciculated. The flowers are bell-shaped, greenish-white to yellowish, long, with six tepals partially fused together at the base; they are produced singly or in clusters of two or three in the junctions of the branchlets. It is usually dioecious, with male ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asparagus (genus)
''Asparagus'' is a genus of flowering plants in the family Asparagaceae, subfamily Asparagoideae. It comprises up to 300 species. Most are evergreen long-lived perennial plants growing from the understory as lianas, bushes or climbing plants. The best-known species is the edible '' Asparagus officinalis'', commonly referred to as just ''asparagus''. Some other members of the genus, such as '' Asparagus densiflorus'', are grown as ornamental plants. Ecology The genus includes a variety of extant forms, occurring from rainforest to semi-desert habitats; many are climbing plants. Most are dispersed by birds. Ornamental species such as '' Asparagus aethiopicus'', '' Asparagus setaceus'' (syn. '' Asparagus plumosus''), and '' Asparagus virgatus'' are finely branched and are misleadingly known as "asparagus fern". In the Macaronesian Islands, several species (such as '' Asparagus umbellatus'' and '' Asparagus scoparius'') grow in moist laurel forest habitat, and preserve the or ...

Cladode
Phylloclades and cladodes are flattened, photosynthesis, photosynthetic shoots, which are usually considered to be modified branches. The two terms are used either differently or interchangeably by different authors. ''Phyllocladus'', a genus of conifer, is named after these structures. Phylloclades/cladodes have been identified in fossils dating from as early as the Permian. Definition and morphology The term "phylloclade" is from the Neo-Latin ''phyllocladium'', itself derived from Greek language, Greek ''phyllo'', leaf, and ''klados'', branch. Definitions of the terms "phylloclade" and "cladode" vary. All agree that they are flattened structures that are photosynthetic and resemble leaf-like branches. In one definition, phylloclades are a subset of cladodes, namely those that greatly resemble or perform the function of leaves, as in Butcher's broom (''Ruscus aculeatus'') as well as ''Phyllanthus'' and some ''Asparagus'' species. By an alternative definition, cladodes are di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aerial Stem Modification
Aerial stem modifications are modifications to the Plant stem, aerial stems, vegetative Bud, buds and Floral morphology, floral buds of plants growing in different conditions and which perform functions such as climbing, protection, support, Biosynthesis, synthesis of food, or vegetative propagation. Aerial Stem, Aerial stem structures that undergo modifications to perform these special functions include Tendril, tendrils, Thorns, spines, and prickles, thorns, hooks, phylloclade, Tuberous root vegetable, tuberous stems, and bulbils. The auxiliary or the terminal part of the modified structures shows their plant stem, stem nature. Tendrils Some weak-stemmed plants produce wiry, coiled, sensitive, and delicate organs for climbing. They are called Tendril, tendrils. These may develop from either the axillary bud or the terminal bud of the stem. In ''Passiflora'', the tendrils develop from the axillary bud. In ''Cissus quadrangularis'' and in ''Vitis vinifera'', the terminal bud ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perennial
In horticulture, the term perennial ('' per-'' + '' -ennial'', "through the year") is used to differentiate a plant from shorter-lived annuals and biennials. It has thus been defined as a plant that lives more than 2 years. The term is also loosely used to distinguish plants with little or no woody growth (secondary growth in girth) from trees and shrubs, which are also technically ''perennials''. Notably, it is estimated that 94% of plant species fall under the category of perennials, underscoring the prevalence of plants with lifespans exceeding two years in the botanical world. Perennials (especially small flowering plants) that 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 the local climate (temperature, moisture, organic content in the soil, microorganisms), a plant that is a peren ...

Carl Linnaeus
Carl Linnaeus (23 May 1707 – 10 January 1778), also known after ennoblement in 1761 as Carl von Linné,#Blunt, Blunt (2004), p. 171. was a Swedish biologist and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern Taxonomy (biology), taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was the son of a curate and was born in Råshult, in the countryside of Småland, southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lily
''Lilium'' ( ) is a genus of herbaceous flowering plants growing from bulbs, all with large and often prominent flowers. Lilies are a group of flowering plants which are important in culture and literature in much of the world. Most species are native to the Northern Hemisphere and their range is temperate climates and extends into the subtropics. Many other plants have "lily" in their common names, but do not belong to the same genus and are therefore not true lilies. True lilies are known to be highly toxic to cats. Description Lilies are tall perennials ranging in height from . They form naked or tunicless scaly underground bulbs which are their organs of perennation. In some North American species the base of the bulb develops into rhizomes, on which numerous small bulbs are found. Some species develop stolons. Most bulbs are buried deep in the ground, but a few species form bulbs near the soil surface. Many species form stem-roots. With these, the bulb grows naturally a ...
