Calliandra Haematocephala
''Calliandra haematocephala'', the red powder puff, is a species of flowering plants of the genus ''Calliandra'' in the family Fabaceae. Description Rambling shrub or small tree with branched pinnate, silky leaves and powder-puff-like balls of conspicuous dark crimson stamens. ''Calliandra haematocephala'' is a fast growing shrub that can grow tall but also spreads wide. If desired it can be kept smaller by trimming. Interesting enough the leaves close at night. The red powder puff flowers are attractive to butterflies and hummingbirds but only appear from November -April in the Northern Hemisphere. The buds before the flowers open look like raspberries. This large shrub can be grown indoor if trimmed and grown in a pot but it will be best if you can grow it outside in a warm climate. Uses Extracts from parts of ''Calliandra haematocephala'' have been used in the green synthesis of zinc oxide nanostructures, magnetite nanoparticles, and silver nanoparticles. Gallery File ...

Justus Carl Hasskarl
Justus Carl Hasskarl (6 December 1811 – 5 January 1894) was a German explorer and botanist specializing in pteridophytes, bryophytes and spermatophytes. Biography Justus Carl Hasskarl was born in Kassel in the Kingdom of Westphalia. In his earlier life he studied at a Botanical Garden, Bonn, plant nursery in Poppelsdorf in 1827. In 1834 he studied natural history while at the same time preparing himself for an expedition to the tropics. In 1836, he traveled to Java and tried to make a living through his knowledge in physics and medicine, with little success. Subsequently, he sent a request to the governor general to work in the Bogor Botanical Gardens, National Botanical Garden and a year later he was appointed assistant curator. With director Johannes Elias Teijsmann, they rearranged their crops to taxonomic families, which would result in the displacement of many specimens in the botanical garden. Together they organized expeditions to various parts of modern Indonesi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (). The term angiosperm is derived from the Ancient Greek, Greek words (; 'container, vessel') and (; 'seed'), meaning that the seeds are enclosed within a fruit. The group was formerly called Magnoliophyta. Angiosperms are by far the most diverse group of Embryophyte, land plants with 64 Order (biology), orders, 416 Family (biology), families, approximately 13,000 known Genus, genera and 300,000 known species. They include all forbs (flowering plants without a woody Plant stem, stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. Angiosperms are distinguished from the other major seed plant clade, the gymnosperms, by having flowers, xylem consisting of vessel elements instead of tracheids, endosperm within their seeds, and fruits that completely envelop the seeds. The ancestors of flowering plants diverged from the commo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calliandra
''Calliandra'' is a genus of flowering plants in the pea family, Fabaceae, in the mimosoid clade of the subfamily Caesalpinioideae. It contains about 140 species that are native to tropical and subtropical regions of the Americas. Description The genus comprises herbaceous perennial plants, shrubs, and rarely small trees, growing tall, with bipinnate leaves. The flowers are produced in cylindrical or globose inflorescences and have numerous long slender stamens which give rise to the common names powder-puff, powder puff plant, and fairy duster. These plants flower all year round, but the best blooming is in spring and summer. They can be easily pruned. Calliandra are often fed on by caterpillars, such as the larvae of statira sulphur (''Aphrissa statira''). It is available in many vibrant colours such as pink, white, etc. Species The following is an alphabetical listing of the 149 species in the genus ''Genus'' that are accepted by Plants of the World Online * '' Callian ...

Fabaceae
Fabaceae () or Leguminosae,International Code of Nomenclature for algae, fungi, and plants. Article 18.5 states: "The following names, of long usage, are treated as validly published: ....Leguminosae (nom. alt.: Fabaceae; type: Faba Mill. Vicia L.; ... When the Papilionaceae are regarded as a family distinct from the remainder of the Leguminosae, the name Papilionaceae is conserved against Leguminosae." English pronunciations are as follows: , and . commonly known as the legume, pea, or bean family, is a large and agriculturally important family of |
Nanoparticle
A nanoparticle or ultrafine particle is a particle of matter 1 to 100 nanometres (nm) in diameter. The term is sometimes used for larger particles, up to 500 nm, or fibers and tubes that are less than 100 nm in only two directions. At the lowest range, metal particles smaller than 1 nm are usually called atom clusters instead. Nanoparticles are distinguished from microparticles (1-1000 μm), "fine particles" (sized between 100 and 2500 nm), and "coarse particles" (ranging from 2500 to 10,000 nm), because their smaller size drives very different physical or chemical properties, like colloidal properties and ultrafast optical effects or electric properties. Being more subject to the Brownian motion, they usually do not sediment, like colloid, colloidal particles that conversely are usually understood to range from 1 to 1000 nm. Being much smaller than the wavelengths of visible light (400-700 nm), nanoparticles cannot be seen with ordinary ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
