Phedimus
''Phedimus'' is a genus of the succulent family Crassulaceae (stonecrop family), with about 18 species, distributed in eastern Europe and Asia. The genus is described with two subgenera, but one of these is also recognized as a separate genus, ''Aizopsis''. ''Phedimus kamtschaticus'' (syn. ''Sedum kamtschaticum'') is widely grown as an ornamental ground cover and has gained the Royal Horticultural Society's Award of Garden Merit. Description Species are perennial or rarely annual herbs, usually glabrous stems, sometimes woody at base, from thin woody rhizome. Leaves decussate or alternate, with narrow base, and several hydathodes on lower face along margins. The flowering branches are erect or descending, with dense inflorescences exhibiting many flowered terminal pleiochasia (several buds come out at the same time). Flowers 4-7 parts, sepals usually unequal, petals free, usually spreading. The fruits are follicles, usually spreading and seeds costate-papillate (incompletely co ...

Sempervivoideae
Sempervivoideae is the largest of three subfamilies in the Saxifragales family Crassulaceae, with about 20–30 genera with succulent leaves. Unlike the two smaller subfamilies, it is distributed in temperate climates. The largest genus in this subfamily is ''Sedum'', with about 470 species. Description Succulent leaved plants. Unlike the other two smaller subfamilies, which are highly derived, Sempervivoideae retain the basic features of the family Crassulaceae. The Sempervivoideae contain many familiar horticultural plants, such as ''Sedum''. Taxonomy Sempervivoideae has taxonomic priority over its synonym, Sedoideae, and is related to the other Crassulaceae subfamilies, as shown in this cladogram, although Messerschmid and colleagues (2020) state that these three subfamily clades are successive sisters, rather than Sempervivoideae being a direct sister only to Kalanchoideae. Subdivisions Six clades within Sempervivoideae have been segregated into five tribes wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phedimus Kamtschaticus
''Phedimus kamtschaticus'', the orange stonecrop, is a species of flowering plant in the family Crassulaceae. It is native to China, Korea, Japan and the Russian Far East north to Chukotka, and has been introduced to the state of New York, Norway, Germany, Austria, and the Baltic States. Under its synonym ''Sedum kamtschaticum'' it has gained the Royal Horticultural Society's Award of Garden Merit The Award of Garden Merit (AGM) is a long-established annual award for plants by the British Royal Horticultural Society (RHS). It is based on assessment of the plants' performance under UK growing conditions. History The Award of Garden Merit .... In addition, the putative variety ''Sedum kamtschaticum'' var. ''ellacombeanum'' and the 'Variegatum' cultivar have also gained the award.

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''.

Aizopsis
''Aizopsis'' is a genus of the succulent family Crassulaceae (stonecrop family), found in east Asia. Description Flowers yellow, chromosome numbers, x=16. Taxonomy In 1978, Ohba divided up the very large and cosmopolitan genus ''Sedum'', placing ''Sedum aizoon'' and allied species into ''Sedum'' subgenus ''Aizoon''. In 1995, he segregated these species into a separate genus, ''Aizopsis''. However, other authors included these species in another segregate, ''Phedimus'', as subgenus ''Aizoon''. Subsequent molecular phylogenetic analysis established ''Aizopsis'' as a sister group to ''Phedimus'', which with distinguishing characteristics justified their retention as a separate genus, although the distinction has not been universally adopted.

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] |

Plant Stems
A stem is one of two main structural axes of a vascular plant, the other being the root. It supports leaves, flowers and fruits, transports water and dissolved substances between the roots and the shoots in the xylem and phloem, stores nutrients, and produces new living tissue. The stem can also be called halm or haulm. The stem is normally divided into nodes and internodes: * The nodes hold one or more leaves, as well as buds which can grow into branches (with leaves, conifer cones, or flowers). Adventitious roots may also be produced from the nodes. * The internodes distance one node from another. The term "shoots" is often confused with "stems"; "shoots" generally refers to new fresh plant growth including both stems and other structures like leaves or flowers. In most plants stems are located above the soil surface but some plants have underground stems. Stems have four main functions which are: * Support for and the elevation of leaves, flowers, and fruits. The stems ke ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chromosome Numbers
Ploidy () is the number of complete sets of chromosomes in a cell, and hence the number of possible alleles for autosomal and pseudoautosomal genes. Sets of chromosomes refer to the number of maternal and paternal chromosome copies, respectively, in each homologous chromosome pair, which chromosomes naturally exist as. Somatic cells, tissues, and individual organisms can be described according to the number of sets of chromosomes present (the "ploidy level"): monoploid (1 set), diploid (2 sets), triploid (3 sets), tetraploid (4 sets), pentaploid (5 sets), hexaploid (6 sets), heptaploid or septaploid (7 sets), etc. The generic term polyploid is often used to describe cells with three or more chromosome sets. Virtually all sexually reproducing organisms are made up of somatic cells that are diploid or greater, but ploidy level may vary widely between different organisms, between different tissues within the same organism, and at different stages in an organism's life cycle.

Novon
The Missouri Botanical Garden is a botanical garden located at 4344 Shaw Boulevard in St. Louis, Missouri. It is also known informally as Shaw's Garden for founder and philanthropist Henry Shaw. Its herbarium, with more than 6.6 million specimens, is the second largest in North America, behind that of the New York Botanical Garden. The '' Index Herbariorum'' code assigned to the herbarium is MO and it is used when citing housed specimens.
