Ruscus
''Ruscus'', commonly known as butcher's broom, is a genus of six species of flowering plants, native to western and southern Europe, Macaronesia, northwestern Africa, and southwestern Asia east to the Caucasus. In the APG III system, APG III classification system, it is placed in the family (biology), family Asparagaceae, subfamily Nolinoideae (formerly the family Ruscaceae). Like many lilioid monocots, it was formerly classified in the family Liliaceae. The species are evergreen shrub-like perennial plants, growing to approximately tall. They have branched stems that bear numerous cladodes (flattened, leaf-like stem tissue, also known as phylloclades) long and broad. The true leaf, leaves are minute, scale-like, and non-photosynthetic. The flowers are small, white with a dark-violet centre, and situated on the middle of the cladodes. The fruit is a red Berry (botany), berry in diameter. Some species are plant sexuality, monoecious while others are plant sexuality, dioecious. ...

Ruscus Aculeatus
''Ruscus aculeatus'', known as butcher's-broom, is a low evergreen dioecious Eurasian shrub, with flat shoots known as cladodes that give the appearance of stiff, spine-tipped leaves. Small greenish flowers appear in spring, and are borne singly in the centre of the cladodes. The female flowers are followed by a red berry, and the seeds are bird-distributed, but the plant also spreads vegetatively by means of rhizomes. It is native to Eurasia and some northern parts of Africa. ''Ruscus aculeatus'' occurs in woodlands and hedgerows, where it is tolerant of deep shade, and also on coastal cliffs. Likely due to its attractive winter/spring color, ''Ruscus aculeatus'' has become a fairly common landscape plant. It is also widely planted in gardens, and has spread as a garden escapee in many areas outside its native range. The plant grows well in zones 7 to 9 on the USDA hardiness zone map. The Latin specific epithet ''aculeatus'' means "prickly". History Etymology The com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ruscus Hypoglossum
''Ruscus hypoglossum'' is a small evergreen shrub with a native range from Italy north to Austria and Slovakia and east to Turkey and Crimea. Common names include spineless butcher's-broom, mouse thorn and horse tongue lily. The species name comes from two Greek words ὑπό (''hypo'') and γλῶσσα (''glōssa'') meaning ''under'' and ''tongue''. Description The mature plant shrub will eventually reach about in height. It has a creeping rootstock and leaf-like phylloclades or flattened stems that are about long to wide tapering at both ends. True leaves are smaller green appendages around the flowers. Small yellow flowers bloom in the axil of a leaf-like bract long on upper side of phylloclade. Plants are dioecious, with male and female flowers produced on separate plants. Fruit is a rarely produced red globose berry wide.

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] |

Ruscus Hyrcanus
''Ruscus hyrcanus'' is a perennial evergreen woody shrub-like or small compact bush plant. It is in the asparagus family. Description and habitat The species grows to approximately tall and is very prickly. Stems always are green; ordinary woody, rigid, branched at the end in a whorl with spreading-procumbent branches. Cladodes have a length of ; they are flattened, ovate, lanceolate, leathery, rigid, and tapering to a thorn at their extremity; their both sides are shiny green. ''R. hyrcanus'' leaves are very reduced, small and bractiform. The flower is purplish or whitish, dioecious, marcescent with six spreading divisions, and solitary or geminate, arising in the axil of a lanceolate, firm bract on the median rib of the upper face of cladodes. Male flower has three stamens and sweating in a tube; female flower has an ovary with three biovulated lobes. The fruit is a red globular berry, about one centimeter in diameter. It is native to Iran, Georgia, Armenia, Azerbaijan and Cr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nolinoideae
Nolinoideae is a monocot subfamily of the family Asparagaceae in the APG III system of 2009. It used to be treated as a separate family, Ruscaceae s.l. The family name is derived from the generic name of the type genus, '' Nolina''. The subfamily includes genera that had been placed in a range of different families, including Ruscaceae s.s., Nolinaceae, Dracaenaceae, Convallariaceae and Eriospermaceae. Like many groups of lilioid monocots, the genera included here were once included in a wide interpretation of the family 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 fai ....

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''. This family includes both common garden plants as well as common houseplants. The garden plants include asparagus, yucca, bluebell, lily of the valley, and hosta, and the houseplants include snake plant, corn cane, spider plant, and plumosus fern. The Asparagaceae is a morphologically heterogenous family with the included species varying widely in their appearance and growth form. It has a cosmopolitan distribution, with genera and species contained in the family native to all continents except Antarctica. Taxonomy Early taxonomy The plant family Asparagaceae was first named, described, and published in Genera Plantarum in 1789 by the French botanist Antoine Laurent de Jussieu, who is particularly noted for his work in developing the concept of pl ...

Plant Sexuality
Plant reproductive morphology is the study of the physical form and structure (the morphology) of those parts of plants directly or indirectly concerned with sexual reproduction. Among all living organisms, flowers, which are the reproductive structures of angiosperms, are the most varied physically and show a correspondingly great diversity in methods of reproduction. Plants that are not flowering plants ( green algae, mosses, liverworts, hornworts, ferns and gymnosperms such as conifers) also have complex interplays between morphological adaptation and environmental factors in their sexual reproduction. The breeding system, or how the sperm from one plant fertilizes the ovum of another, depends on the reproductive morphology, and is the single most important determinant of the genetic structure of nonclonal plant populations. Christian Konrad Sprengel (1793) studied the reproduction of flowering plants and for the first time it was understood that the pollination pr ...
