Ledebouria Revoluta
''Ledebouria revoluta'', the south Indian squill, is a flowering plant species in the genus ''Ledebouria'' found in Southern Africa and India. Description The leaves of ''Ledebouria revoluta'' are smooth and fleshy, and unlike those of some other ''Ledebouria'' species they are present when the flowers emerge. The leaves' venation is obscure and their margins are usually a similar colour to the rest of the leaf. The flowers are born densely, often on multiple, drooping inflorescences. The flowers are purple-to-pink, with pink pedicels and pale yellow anthers. The ovary has 6 lobes and the seeds are a brown colour. Unlike some other ''Ledebouria'' species, both the leaves and bulb scales of ''L. revoluta'' have threads when torn.Venter, S. & Edwards, Trevor. (1998).

Ledebouria
''Ledebouria'' is a genus of African bulbous perennial herbs in the Asparagus family, Asparagaceae, subfamily Scilloideae. Most members were previously part of the genus ''Scilla''. A number of species are grown by cacti and succulent enthusiasts for their patterned leaves. Most of the species are native to Madagascar and Africa (except North Africa), but a few are from India, Sri Lanka or the Arabian Peninsula. The genus name of ''Ledebouria'' is in honour of Carl Friedrich von Ledebour (1786–1851), a German- Estonian botanist. It was first described and published in Nov. Pl. Sp. on page 194 in 1821.

Inflorescence
In botany, an inflorescence is a group or cluster of flowers arranged on a plant's Plant stem, stem that is composed of a main branch or a system of branches. An inflorescence is categorized on the basis of the arrangement of flowers on a main axis (Peduncle (botany), peduncle) and by the timing of its flowering (determinate and indeterminate). Morphology (biology), Morphologically, an inflorescence is the modified part of the Shoot (botany), shoot of spermatophyte, seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internode (botany), internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. General characteristics Inflorescences are described by many different charact ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Homoisoflavanone
Homoisoflavonoids (3-benzylidenechroman-4-ones) are a type of phenolic compounds occurring naturally in plants. Chemically, they have the general structure of a 16-carbon skeleton, which consists of two phenyl rings (A and B) and heterocyclic ring (C). Synthesis Homoisoflavones can be synthesized from 2'-hydroxy dihydrochalcones. Homoisoflavanones can be synthesized from 3,5-methoxy phenols via chroman-4-one in three steps or from phloroglucinol. ;Conversion Homoisoflavanes can be obtained from the conversion of homoisoflavonoids. Natural occurrences The homoisoflavonoids portulacanones A, B, C and D can be found in '' Portulaca oleracea'' (common purslane, Caryophyllales, Portulacaceae). The 3,4-dihydroxyhomoisoflavans sappanol, episappanol, 3'-deoxysappanol, 3'-O-methylsappanol and 3'-O-methylepisappanol can be found in ''Caesalpinia sappan''. The homoisoflavones scillavones A and B can be isolated from the bulbs of ''Scilla scilloides'' ('' Barnardia japonica'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Friedrich Von Ledebour
Carl Friedrich von Ledebour (8 July 1786 in Stralsund – 4 July 1851 in Munich;NDB/ADB Deutsche Biographie also Karl Friedrich von Ledebour) was a Baltic German botanist. Between 1811 and 1836, he was professor of science in the University of Tartu, Estonia. His most important works were ''Flora Altaica'', the first flora (plants), Flora of the Altay Mountains, published in 1833, and ''Flora Rossica'', published in four volumes between 1841 and 1853, the first complete flora of the Russian Empire. New species he described for the first time in the ''Flora Altaica'' include ''Malus sieversii'' (as ''Pyrus sieversii''), the wild ancestor of the apple, and the Siberian Larch (''Larix sibirica''). The plant genera ''Ledebouria'' (in the Asparagus family, Asparagaceae), and ''Ledebouriella'' (from the family Apiaceae) ar ...

Flora Of Southern Africa
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is '' funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora'' for purposes of specificity. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) wa ...
