Arctium Minus
''Arctium minus'', commonly known as lesser burdock, little burdock, louse-bur, common burdock, button-bur, cuckoo-button, or wild rhubarb, is a biennial plant native to Europe. Description ''Arctium minus'' is a biennial plant growing up to tall and form multiple branches. It is large and bushy. The leaves are up to long and ovate. The lower leaves are heart-shaped and have very wavy margins. Leaves are dark green above and woolly below. It grows an extremely deep taproot, up to into the ground. The plant produces flowers in its second year of growth, from July to October. The flowers are prickly and pink to purple in color. The flower heads are about wide, surrounded by a cluster of bracts. The outer bracts end in hooks causing a hook-and-loop effect after the flower head dries, when the bracts will attach to humans and animals to transport the seedhead. The flowers resemble and can be easily mistaken for thistles, but burdock can be distinguished by its extremely large l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Johann Jakob Bernhardi
Johann Jakob Bernhardi (1 September 1774, in Erfurt – 13 May 1850, in Erfurt) was a German doctor and botanist. Biography Johann J. Bernhardi studied Medicine and Botany at the University of Erfurt, and after graduation practiced medicine for a time in his native city. In 1799 he was named director of the botanical garden at ''Gartenstraße'', and in 1809 was appointed professor of botany, zoology, mineralogy and materia medica at the university. He served as director of the botanical garden until his death in 1850, being buried in the central avenue of this botanical garden. Throughout his life thanks to acquisitions and interchanges with other botanists, he assembled a considerable herbarium of 60,000 plants with specimens from North America, South America, Asia, and Africa. After his death this herbarium did not remain in Germany but due to the efforts of George Engelmann, who, in 1857, shortly after the death of Bernhardi bought the complete herbarium for the amount of 600 do ...

Biennial Plant
A biennial plant is a flowering plant that, generally in a temperate climate, takes two years to complete its biological life cycle. Background In its first year, the biennial plant undergoes primary growth, during which its vegetative structures (leaves, stems, and roots) develop. Usually, the stem of the plant remains short and the leaves are low to the ground, forming a rosette. After one year's growing season, the plant enters a period of dormancy for the colder months. Many biennials require a cold treatment, or vernalization before they will flower. During the next spring or summer, the stem of the biennial plant elongates greatly, or "bolts". The plant then flowers, producing fruits and seeds before it finally dies. There are far fewer biennials than either perennial plants or annual plants. Biennials do not always follow a strict two-year life cycle: most plants in the wild can take three or more years to mature. Rosette leaf size has been found to predict when a pla ...

Leaves
A leaf (: leaves) is a principal appendage of the stem of a vascular plant, usually borne laterally above ground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the shoot system. In most leaves, the primary photosynthetic tissue is the palisade mesophyll and is located on the upper side of the blade or lamina of the leaf, but in some species, including the mature foliage of ''Eucalyptus'', palisade mesophyll is present on both sides and the leaves are said to be isobilateral. The leaf is an integral part of the stem system, and most leaves are flattened and have distinct upper ( adaxial) and lower ( abaxial) surfaces that differ in color, hairiness, the number of stomata (pores that intake and output gases), the amount and structure of epicuticular wax, and other features. Leaves are mostly green in color due to the presence of a compound called chlorop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bracts
In botany, a bract is a modified or specialized leaf, associated with a reproductive structure such as a flower, inflorescence axis or cone scale. Bracts are usually different from foliage leaves in size, color, shape or texture. They also look different from the parts of the flower, such as the petals or sepals. A plant having bracts is referred to as bracteate or bracteolate, while one that lacks them is referred to as ebracteate or ebracteolate. Variants Some bracts are brightly coloured which aid in the attraction of pollinators, either together with the perianth or instead of it. Examples of this type of bract include those of '' Euphorbia pulcherrima'' (poinsettia) and '' Bougainvillea'': both of these have large colourful bracts surrounding much smaller, less colourful flowers. In grasses, each floret (flower) is enclosed in a pair of papery bracts, called the lemma (lower bract) and palea (upper bract), while each spikelet (group of florets) has a further pair of ...

Hook-and-loop Fastener
Hook-and-loop fasteners, commonly known as Velcro (a Generic trademark, genericized trademark), hook-and-pile fasteners or touch fasteners are versatile fastening devices that allow two surfaces to be repeatedly attached and detached with ease. Invented in the mid-20th century, they are widely used in clothing, accessories, and various industrial and consumer applications. The fastener consists of two complementary components: one with tiny hooks and the other with soft loops. When pressed together, the hooks catch the loops, creating a secure but temporary bond. The fasteners can be separated by peeling or pulling the surfaces apart, often producing a distinctive ripping sound. History The original hook-and-loop fastener was conceived in 1941 by Swiss engineer George de Mestral, which he named velcro.The word Velcro is a portmanteau of two French words: "velours" meaning velvet, and "crochet" meaning hook. The idea came to him one day after he returned from a hunting trip wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
