Crassulaceae Genera
The Crassulaceae (from Latin ''crassus'', thick), also known as the stonecrop family or the orpine family, are a diverse family of dicotyledon flowering plants characterized by succulent leaves and a unique form of photosynthesis, known as Crassulacean acid metabolism (CAM). Flowers generally have five floral parts. Crassulaceae are usually herbaceous but there are some subshrubs, and relatively few treelike or aquatic plants. Crassulaceae are a medium size monophyletic family in the core eudicots, among the order Saxifragales, whose diversity has made infrafamilial classification very difficult. The family includes approximately 1,400 species and 34–35 genera, depending on the circumscription of the genus ''Sedum'', and distributed over three subfamilies. Members of the Crassulaceae are found worldwide, but mostly in the Northern Hemisphere and southern Africa, typically in dry and/or cold areas where water may be scarce, although a few are aquatic. Crassulaceae are mainly per ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crassula Perfoliata
''Crassula perfoliata'' is the type species of the genus ''Crassula'', in the flowering plant family Crassulaceae, where it is placed in the subfamily Crassuloideae. It was first formally described by Linnaeus in 1753 as one of 10 species of ''Crassula''. It is from South Africa. Two varieties are recognized: * ''C. perfoliata'' var. ''falcata'' (J.C.Wendl.) Toelken * ''C. perfoliata'' var. ''heterotricha'' ( Schinz) Toelken ''Crassula perfoliata'' var. ''falcata'', known as the airplane plant or airplane propellers, has gained the Royal Horticultural Society's Award of Garden Merit. Growing to tall and broad, this succulent evergreen subshrub has grey erect leaves and scarlet flowers in summer. As it does not tolerate freezing temperatures, in temperate zones it must be grown under glass using a cactus compost.

Sedum
''Sedum'' is a large genus of flowering plants in the family Crassulaceae, members of which are commonly known as stonecrops. The genus has been described as containing up to 600 species, subsequently reduced to 400–500. They are leaf succulents found primarily in the Northern Hemisphere, but extending into the southern hemisphere in Africa and South America. The plants vary from annual and creeping herbs to shrubs. The plants have water-storing leaves. The flowers usually have five petals, seldom four or six. There are typically twice as many stamens as petals. Various species formerly classified as ''Sedum'' are now in the segregate genera '' Hylotelephium'' and ''Rhodiola''. Well-known European species of ''Sedum'' are ''Sedum acre'', ''Sedum album'', '' Sedum dasyphyllum'', '' Sedum reflexum'' (also known as ''Sedum rupestre'') and ''Sedum hispanicum''. Description ''Sedum'' is a genus that includes annual, biennial, and perennial herbs. They are characterised by succulen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kalanchoe Pinnata
''Kalanchoe pinnata'', commonly known as cathedral bells, air plant, life plant, miracle leaf, and Goethe plant is a succulent plant native to Madagascar. It is a popular houseplant and has become naturalized in tropical and subtropical areas. The species is distinctive for the profusion of miniature plantlets that form on the margins of its phylloclades, a trait it has in common with some other members of ''Bryophyllum'' (now included in ''Kalanchoe''). It is a succulent, perennial plant, about tall, with fleshy cylindrical stems and young growth of a reddish tinge, which can be found in flower throughout most of the year. The specific epithet "pinnata" is the feminine form of the Latin adjective ''pinnatus'', meaning "winged, pinnate". Description The leaves of this species are thick, fleshy, elliptical in shape, curved, with a crenate or serrated margin, often reddish. Simple at the base of the stem, the leaves are imparipinnate at the top, long, with three to five pairs of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aeonium Arboreum
''Aeonium arboreum'', the tree aeonium, tree houseleek, or Irish rose, is a succulent, subtropical subshrub in the flowering plant family Crassulaceae. It is an invasive weed in places outside its natural distribution, for example as a garden escape throughout temperate southern Australia. Description ''Aeonium arboreum'' grows as a less branched subshrub and reaches stature heights of up to 2 metres. The more or less upright or ascending, smooth, not net-like patterned stem axes have a diameter of 1 to 3 centimetres. Their leaves are in flattened rosettes with diameters of 10 to 25 centimetres at the end of the stem axes together. Young leaves are pressed tightly together. The obovate to oblate lanceolate leaf blade is pointed toward its apex and wedge-shaped at the base. It is long, wide and 1.5 to 3 millimetres thick. The green, usually purple-colored, glossy leaf surface is almost bare. The leaf margin is set with curved eyelashes. The conical to ovate inflorescence has ...

Cotyledon (genus)
''Cotyledon'' is one of some 35 genera of succulent plants in the family Crassulaceae. Mostly from Southern Africa, they also occur throughout the drier parts of Africa as far north as the Arabian Peninsula. Ten of its species are mostly confined to South Africa, where unlike '' Tylecodon'', they occur commonly in both the winter and summer rainfall regions. They may be found on coastal flats and rocky hillsides, or as cremnophytes on cliff faces. Their decussate, evergreen leaves are very variable in shape, even within some species, but the flowers are, apart from colour, very similar. Description Members of the genus are shrublets, generally succulent, with fleshily woody, brittle stems and persistent succulent leaves. The leaves are opposite. Leaf pairs generally are oriented at 90 degrees to their preceding and following pairs, as is common in the family Crassulaceae, but the leaf habit differs from say '' Tylecodon'' (in which the leaves are borne in spirals and are ...

Echeveria
''Echeveria'' is a large genus of flowering plants in the family Crassulaceae, native to semi-desert areas of Central America, Mexico and northwestern South America. Description Plants may be evergreen or deciduous. Flowers on short stalks (cymes) arise from compact rosettes of succulent fleshy, often brightly coloured leaves. Species are polycarpic, meaning that they may flower and set seed many times over the course of their lifetimes. Often numerous offsets are produced, and are commonly known as "hen and chicks", which can also refer to other genera, such as ''Sempervivum'', that are significantly different from ''Echeveria''. Many species of ''Echeveria'' serve important environmental roles, such as those of host plants for butterflies. For example, the butterfly ''Callophrys xami'' uses several species of ''Echeveria'', such as ''Echevelia gibbiflora'', for suitable host plants. Even more, these plants are integral to the oviposition process of ''C. xami'' and some other b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bryophyllum
''Bryophyllum'' (from the Greek ''bryon/bryein'' = sprout, ''phyllon'' = leaf) is a group of plant species of the family Crassulaceae native to Madagascar. It is a section or subgenus within the genus ''Kalanchoe'', and was formerly placed at the level of genus. This section is notable for vegetatively growing small plantlets on the fringes of the leaves; these eventually drop off and root. These plantlets arise from mitosis of meristematic-type tissue in notches in the leaves. Nowadays, bryophyllums are naturalized in many parts of the tropics and subtropics, and deliberately cultivated for their attractiveness or for their interesting reproduction as a vegetative reproductive plant. Taxonomy Species of ''Bryophyllum'' are nested within ''Kalanchoe'' on molecular phylogenetic analysis. Therefore, ''Bryophyllum'' should be a section of ''Kalanchoe'' rather than a separate genus. The number of species within ''Bryophyllum'' varies with definitions of this section. ''Br ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Umbilicus (plant)
''Umbilicus'' is a genus of over ninety species of flowering plants in the family Crassulaceae. Many of its species have been given synonyms under different genera such as '' Rosularia'', ''Cotyledon'', and ''Chiastophyllum''. However, those that remain in ''Umbilicus'' are listed below: *'' Umbilicus chloranthus'' (called green Venus' navel) *'' Umbilicus chrysanthus'' (called Venus' navel) *'' Umbilicus erectus'' (called reniform Venus' navel) *'' Umbilicus horizontalis'' (called horizontal navelwort) *'' Umbilicus intermedius'' (called intermediate navelwort) *'' Umbilicus oppositifolius'' (called gold drop) (also as ''Chiastophyllum o.'') *''Umbilicus rupestris'' (called navelwort) ;Other (unnamed) species *'' Umbilicus aetneus'' (Tornab) *'' Umbilicus affinis'' (Schrenk) *'' Umbilicus aizoon'' (Fenzl) *'' Umbilicus albido-opacus'' (Carlström), sometimes referred to as opacus. *'' Umbilicus alpestris'' (Karelin and Kirilov) *'' Umbilicus botryoides'' (Hochstetter) ...

Monanthes
''Monanthes'' is a genus of small, succulent, subtropical plants of the family Crassulaceae. The about ten species are mostly endemic to the Canary Islands and Savage Islands, with some found on Madeira. Its center of diversity is Tenerife, with seven species occurring on this island. On Fuerteventura and Lanzarote, only ''M. laxiflora'' occurs. ''Monanthes'' is a rare example where a species re-colonizes the continent from an island, after their ancestors have colonized the island from the continent. ''Monanthes'' are not frost-resistant. They are linked with the genera ''Sempervivum'', ''Greenovia'', ''Aichryson'' and ''Aeonium'', which is obvious from their similar flowers. Species of ''Monanthes'' differ considerably in life- and growth-form. ''M. icterica'', which is also genetically quite distant to other ''Monanthes'' species, is annual, while the other species are perennial. Taxonomy Accepted species include: * '' Monanthes anagensis'' Praeger * ''Monanthes atlantica'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hen And Chicks
Hen and chicks (also known as hen-and-chickens, or hen-widdies in the southern United States) is a common name for a group of small succulent plants, a term that indicates a plant that possesses enlarged parts to store water. It belongs to the flowering plant family Crassulaceae, native to southern Europe and northern Africa. The plants grow close to the ground with leaves formed around each other in a Rosette (botany), rosette, and propagating by offset (botany), offsets. The "hen" is the main, or mother, plant, and the "chicks" are a flock of offspring, which start as tiny buds on the main plant and soon sprout their own roots, taking up residence close to the mother plant. Plants commonly referred to as "Hens and chicks" include ground-hugging species of ''Sempervivum'' (houseleeks) such as ''Sempervivum'' 'Pekinese', ''Sempervivum arachnoideum, S. arachnoideum'' (cobweb houseleek), and ''Sempervivum tectorum, S. tectorum'' (common houseleek), as well as members of the rela ...

Sempervivum
''Sempervivum'' (Brit. , U.S. sɛ̃mpeɹ'vivũm is a genus of about 40 species of flowering plants in the family Crassulaceae, commonly known as houseleeks. Other common names include liveforever (the source of the taxonomical designation ''Sempervivum'', literally "always/forever alive") and hen and chicks, a name shared with plants of other genera as well. They are succulent perennials forming mats composed of tufted leaves in rosettes. In favourable conditions they spread rapidly via offsets, and several species are valued in cultivation as groundcover for dry, sunny locations. Habitat Houseleeks exist from Morocco to Iran, through the mountains of Iberia, the Alps, Carpathians, Balkan mountains, Turkey, the Armenian mountains, in the northeastern part of the Sahara Desert, and the Caucasus. Their ability to store water in their thick leaves allows them to live on sunny rocks and stony places in the mountain, subalpine and alpine belts. Most are hardy to US zone 4, and will ...

Kalanchoe Blossfeldiana
''Kalanchoe blossfeldiana'' is a herbaceous and commonly cultivated house plant of the genus ''Kalanchoe'' native to Madagascar. It is known by the English common names flaming Katy, Christmas kalanchoe, florist kalanchoe and Madagascar widow's-thrill. Taxonomy and naming ''Kalanchoe blossfeldiana'' is in the ''Kalanchoe ''section of the ''Kalanchoe ''genus, with a description of the plant published in 1934 (Repert. Spec. Nov. Regni Veg. 35:159). Regarding the etymology of the binomial, Adanson adapted the generic name ''Kalanchoe'' from 'Kalanchauhuy', a Chinese name for one species recorded by Georg Joseph Kamel, a botanist and Jesuit missionary to the Philippines. The Oxford English Dictionary states that it is "based on heChinese 伽藍菜 gāláncài", whilst the Collins English Dictionary merely restates the claim that the generic name was derived from the local Chinese name for one of the species. The specific epithet ''blossfeldiana'' is in tribute to German hybridise ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
