Geranium
''Geranium'' is a genus of 422 species of annual, biennial, and perennial plants that are commonly known as geraniums or cranesbills. They are found throughout the temperate regions of the world and the mountains of the tropics, but mostly in the eastern part of the Mediterranean region. The palmately cleft leaves are broadly circular in form. The flowers have five petals and are coloured white, pink, purple or blue, often with distinctive veining. Geraniums will grow in any soil as long as it is not waterlogged. Propagation is by semiripe cuttings in summer, by seed, or by division in autumn or spring. Geraniums are eaten by the larvae of some Lepidoptera species including brown-tail, ghost moth, and mouse moth. At least several species of ''Geranium'' are gynodioecious. The species ''Geranium viscosissimum'' (sticky geranium) is considered to be protocarnivorous. Name The genus name is derived from the Greek (''géranos'') or (''geranós'') ' crane'. The English name ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hyperin
Hyperoside is a chemical compound. It is the 3-''O''-galactoside of quercetin. Natural occurrences Hyperoside has been isolated from ''Drosera rotundifolia'', from the Lamiaceae ''Stachys sp.'' and ''Prunella vulgaris'', from ''Rumex acetosella'', ''Cuscuta chinensis'' seeds, from St John's wort and from ''Camptotheca acuminata''. It is one of the phenolic compounds in the invasive plant ''Carpobrotus edulis'' and contributes to the antibacterial properties of the plant. In ''Rheum nobile'' and '' R. rhaponticum'', it serves as a UV blocker found in the bracts. It is also found in ''Geranium niveum'' and ''Taxillus kaempferi ''Taxillus kaempferi'' () is a parasitic plant A parasitic plant is a plant that derives some or all of its nutritional requirements from another living plant.
