Phaneroglossa
''Phaneroglossa'' is a genus of plants that is assigned to the daisy family. It consists of only one species, ''Phaneroglossa bolusii'', a perennial plant of up to high, that has leathery, line- to lance-shaped, seated leaves with mostly few shallow teeth and flower heads set individually on top of long stalks. The flower head has an involucre of just one whorl of bracts, few elliptic, white or cream ray florets, and many yellow disc florets. It is an endemic species of the Western Cape province of South Africa. Flowering mainly occurs from November to January. Description ''Phaneroglossa'' is a low, up to high, perennial plant that is hairless except for the woolly leaf axils, and has short, woody, upwardly inclined stems. Its leaves are crowded on the short stems, leathery in consistency, and set alternately along the stem. The leaves are line-, lance- or inverted lance-shaped, with a conspicuous midvein, seated with the base more of less clasping the stem, with an entire ma ...

Asteraceae
The family Asteraceae, alternatively Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales. Commonly referred to as the aster, daisy, composite, or sunflower family, Compositae were first described in the year 1740. The number of species in Asteraceae is rivaled only by the Orchidaceae, and which is the larger family is unclear as the quantity of extant species in each family is unknown. Most species of Asteraceae are annual, biennial, or perennial herbaceous plants, but there are also shrubs, vines, and trees. The family has a widespread distribution, from subpolar to tropical regions in a wide variety of habitats. Most occur in hot desert and cold or hot semi-desert climates, and they are found on every continent but Antarctica. The primary common characteristic is the existence of sometimes hundreds of tiny individual florets which are held together by protective involucres in flower heads, or more technicall ...

Petal
Petals are modified Leaf, leaves that surround the reproductive parts of flowers. They are often advertising coloration, brightly colored or unusually shaped to attract pollinators. All of the petals of a flower are collectively known as the ''corolla''. Petals are usually accompanied by another set of modified leaves called sepals, that collectively form the ''calyx'' and lie just beneath the corolla. The calyx and the corolla together make up the perianth, the non-reproductive portion of a flower. When the petals and sepals of a flower are difficult to distinguish, they are collectively called tepals. Examples of plants in which the term ''tepal'' is appropriate include Genus, genera such as ''Aloe'' and ''Tulipa''. Conversely, genera such as ''Rose, Rosa'' and ''Phaseolus'' have well-distinguished sepals and petals. When the undifferentiated tepals resemble petals, they are referred to as "petaloid", as in petaloid monocots, orders of monocots with brightly colored tepals. Sinc ...

Phylogenetic Tree
A phylogenetic tree (also phylogeny or evolutionary tree Felsenstein J. (2004). ''Inferring Phylogenies'' Sinauer Associates: Sunderland, MA.) is a branching diagram or a tree showing the evolutionary relationships among various biological species or other entities based upon similarities and differences in their physical or genetic characteristics. All life on Earth is part of a single phylogenetic tree, indicating common ancestry. In a ''rooted'' phylogenetic tree, each node with descendants represents the inferred most recent common ancestor of those descendants, and the edge lengths in some trees may be interpreted as time estimates. Each node is called a taxonomic unit. Internal nodes are generally called hypothetical taxonomic units, as they cannot be directly observed. Trees are useful in fields of biology such as bioinformatics, systematics, and phylogenetics. ''Unrooted'' trees illustrate only the relatedness of the leaf nodes and do not require the ancestral root to b ...

Dendrosenecio
''Dendrosenecio'' is a genus of flowering plants in the Asteraceae, sunflower family. It is a segregate (taxonomy), segregate of ''Senecio'', in which it formed the subgenus ''Dendrosenecio''. Its members, the giant groundsels, are native to the higher altitude zones of ten mountain groups in equatorial East Africa, where they form a conspicuous element of the flora. Description They have a giant rosette habit, with a terminal leaf rosette at the apex of a stout woody stem. When they bloom, the flowers form a large terminal inflorescence. Concomitantly, two to four lateral branches are normally initiated. As a result, old plants have the appearance of candelabras the size of telephone poles, each branch with a terminal rosette. Species ''Dendrosenecio'' varies geographically between mountain ranges, and altitudinally on a single mountain. There has been disagreement among botanists as to which populations of ''Dendrosenecio'' warrant recognition as species, and which should be r ...

Sequence Homology
Sequence homology is the biological homology between DNA, RNA, or protein sequences, defined in terms of shared ancestry in the evolutionary history of life. Two segments of DNA can have shared ancestry because of three phenomena: either a speciation event (orthologs), or a duplication event (paralogs), or else a horizontal (or lateral) gene transfer event (xenologs). Homology among DNA, RNA, or proteins is typically inferred from their nucleotide or amino acid sequence similarity. Significant similarity is strong evidence that two sequences are related by evolutionary changes from a common ancestral sequence. Alignments of multiple sequences are used to indicate which regions of each sequence are homologous. Identity, similarity, and conservation The term "percent homology" is often used to mean "sequence similarityā€¯, that is the percentage of identical residues (''percent identity''), or the percentage of residues conserved with similar physicochemical properties (' ...

Taxonomy (biology)
In biology, taxonomy () is the scientific study of naming, defining ( circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxa (singular: taxon) and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain, kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class, order, family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, as he developed a ranked system known as Linnaean taxonomy for categorizing organisms and binomial nomenclature for naming organisms. With advances in the theory, data and analytical technology of biological systematics, the Linnaean system has transformed into a system of modern biological classification intended to reflect the evolu ...

Ceres, Western Cape
Ceres is the administrative centre and largest town of the Witzenberg Local Municipality in the Western Cape Province of South Africa. Ceres serves as a regional centre for the surrounding towns of Wolseley, Tulbagh, Op-die-Berg and Prince Alfred Hamlet. It is situated in the ''Warmbokkeveld'' (Afrikaans: "warm antelope field") Valley about 170 km north-east of Cape Town. Ceres is located at the north-eastern entrance to Michell's Pass and was the old route north between Cape Town and Johannesburg, which was later replaced by the N1 highway, which traverses the Breede River Valley to the south. Named after the Roman goddess of agriculture, Ceres, a name which is fitting as the valley in which the town is situated is extremely fertile and is a major producer of South Africa's deciduous fruit. Geography and climate Ceres experiences a typical Mediterranean climate tempered by its altitude. The town experiences warmer temperatures in summer, due to its inland location with ...

Michell's Pass
Michell's Pass is a mountain pass in the Western Cape province of South Africa which approaches the town of Ceres from the south-west, connecting it to Tulbagh, Worcester and the Breede River Valley. The pass is traversed by the R46 road and the Ceres branch line railway, which was re-opened for use by the Ceres Rail Company and seasonally by Transnet Freight Rail in terms of an agreement between the Ceres Rail Company and Transnet in 2012. From its western entrance near Wolseley the pass ascends to the summit at an elevation of , before descending a short distance into Ceres.Ceres Rail Company: The Story So Far (Accessed on 16 June 2017) [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
