Massonia Dentata
''Massonia'' is a genus of bulbous perennial flowering plants in the family Asparagaceae, subfamily Scilloideae (also treated as the family Hyacinthaceae). It is native to southern Africa, and is found in localities such as Namaqualand with hot and dry summers, being dormant in summer and growing during winter. The genus ''Whiteheadia'' has been merged into ''Massonia''. It is classed as a cryptophyte. The genus is named for Francis Masson, a Scottish botanist, gardener, and Kew Gardens’ first plant hunter. Description ''Massonia'' grows from underground bulbs whose outer tunic is pale brown and papery or leathery. Two relatively broad leaves appear at the same time as the flowers, spreading out on either side, sometimes lying flat on the ground. The flowers are borne in a raceme, which may be short and held at ground level. There may be a "tuft" of green bracts at the top of the inflorescence. Individual flowers are pale in colour, white, or with green, yellow or pink tones. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tepal
A tepal is one of the outer parts of a flower (collectively the perianth). The term is used when these parts cannot easily be classified as either sepals or petals. This may be because the parts of the perianth are undifferentiated (i.e. of very similar appearance), as in ''Magnolia'', or because, although it is possible to distinguish an outer whorl of sepals from an inner whorl of petals, the sepals and petals have similar appearance to one another (as in ''Lilium''). The term was first proposed by Augustin Pyramus de Candolle in 1827 and was constructed by analogy with the terms "petal" and "sepal". (De Candolle used the term ''perigonium'' or ''perigone'' for the tepals collectively; today, this term is used as a synonym for ''perianth''.) p. 39. Origin Undifferentiated tepals are believed to be the ancestral condition in flowering plants. For example, ''Amborella'', which is thought to have separated earliest in the evolution of flowering plants, has flowers with undiffer ...

Plants Of The World Online
Plants of the World Online (POWO) is an online taxonomic database published by the Royal Botanic Gardens, Kew. History Following the Convention on Biological Diversity, the Royal Botanic Gardens in Kew launched Plants of the World Online in March 2017 with the goal of creating an exhaustive online database of all seed-bearing plants worldwide. (Govaerts wrongly speaks of "Convention for Botanical Diversity (CBD)). The initial focus was on tropical African flora, particularly flora ''Zambesiaca'', flora of West and East Tropical Africa. Since March 2024, the website has displayed AI-generated predictions of the extinction risk for each plant. Description The database uses the same taxonomical source as the International Plant Names Index, which is the World Checklist of Vascular Plants (WCVP). The database contains information on the world's flora gathered from 250 years of botanical research. It aims to make available data from projects that no longer have an online ...

Lachenalia
''Lachenalia'' is a genus of bulbous perennial plants in the family Asparagaceae, subfamily Scilloideae, which are usually found in Namibia and South Africa. Most of them have a dormancy period, but new roots will always grow every year. ''Lachenalia'' is named after the Swiss botanist Werner de Lachenal (1736-1800). Species are sometimes known as Cape cowslip, though they are not even somewhat related to the true cowslip ''Primula veris''. Species , the ''Plants of the World Online'' accepted 136 species:Search for "Lachenalia", *'' Lachenalia alba'' W.F.Barker ex G.D.Duncan *'' Lachenalia algoensis'' Schönland *'' Lachenalia aloides'' (L.f.)

Paraphyly
Paraphyly is a taxonomic term describing a grouping that consists of the grouping's last common ancestor and some but not all of its descendant lineages. The grouping is said to be paraphyletic ''with respect to'' the excluded subgroups. In contrast, a monophyletic grouping (a clade) includes a common ancestor and ''all'' of its descendants. The terms are commonly used in phylogenetics (a subfield of biology) and in the tree model of historical linguistics. Paraphyletic groups are identified by a combination of synapomorphies and symplesiomorphies. If many subgroups are missing from the named group, it is said to be polyparaphyletic. The term received currency during the debates of the 1960s and 1970s accompanying the rise of cladistics, having been coined by zoologist Willi Hennig to apply to well-known taxa like Reptilia (reptiles), which is paraphyletic with respect to birds. Reptilia contains the last common ancestor of reptiles and all descendants of that ancest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Molecular Phylogenetics
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetics, phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in Taxonomy (biology), taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tre ...

Maarten Houttuyn
Maarten Houttuyn or Houttuijn (1720 – 2 May 1798; Latinised as Martinus Houttuyn) was a Dutch naturalist. Houttuyn was born in Hoorn, studied medicine in Leiden and moved to Amsterdam in 1753. He published many books on natural history, e.g. ''Natuurlyke Historie of uitvoerige Beschryving der Dieren, Planten en Mineraalen, volgens het Samenstel van den Heer Linnaeus'', in 37 volumes (1761-1773), following Carl Linnaeus' division into the animal kingdom, the plant kingdom, and the mineral kingdom. His areas of interest encompassed Pteridophytes, Bryophytes and Spermatophytes. He died in Amsterdam. In botanical nomenclature, the standard author abbreviation ''Houtt.'' is applied to plants described by him. He is commemorated by the genus '' Houttuynia'', a member of the Saururaceae from China and Japan. Martinus Houttuyn was the co-writer of the volumes 2, 3, 4 and 5 of '' Nederlandsche Vogelen''.His name appears on the title pages ovol 2 an of ''Nederlandsche Vogelen' ...

Carl Peter Thunberg
Carl Peter Thunberg, also known as Karl Peter von Thunberg, Carl Pehr Thunberg, or Carl Per Thunberg (11 November 1743 – 8 August 1828), was a Sweden, Swedish Natural history, naturalist and an Apostles of Linnaeus, "apostle" of Carl Linnaeus. After studying under Linnaeus at Uppsala University, he spent seven years travelling in southern Italy and Asia, collecting and describing people and animals new to European science, and observing local cultures. He has been called "the father of South African botany", "pioneer of Occidental Medicine in Japan", and the "Japanese Carl Linnaeus, Linnaeus". Early life Thunberg was born and grew up in Jönköping, Sweden. At the age of 18, he entered Uppsala University where he was taught by Carl Linnaeus, regarded as the "father of modern Taxonomy (biology), taxonomy". Thunberg graduated in 1767 after 6 years of studying. To deepen his knowledge in botany, medicine and natural history, he was encouraged by Linnaeus in 1770 to travel to P ...

Gerbillurus Paeba
The hairy-footed gerbil (''Gerbillurus paeba'') is a species of rodent found in Angola, Botswana, Mozambique, Namibia, South Africa, and Zimbabwe. Its natural habitats are dry savanna, temperate shrubland, hot deserts, sandy shores, and urban areas. All members of this genus have hair on the soles of their feet, hence the name. They prefer sandy soil or sandy alluvium with grass, scrub or light woodland cover. Description The hairy-footed gerbil weighs around , smaller than other ''Gerbillurus'' species. They have a head-and-body length of around , and a tail length of . Distinctive to this genus are the soles of the feet, which have hair tufts on them, and hairs on each toe. The coloring of the paeba is similar to other ''Gerbillurus'' members. However, coloring varies with precise locality and population. The upper parts of the body are reddish-orange to a greyish-red, whereas other ''Gerbillurus'' members may be a bit darker. The underparts are always white and the tail is th ...
