Buddleja Bhutanica
''Buddleja bhutanica'' is a species of flowering shrub endemic to Bhutan, where it grows in bush on mountain slopes at elevations around 1,700 m.Stuart, D. (2006). ''Buddlejas''. RHS Plant Collector Guide. Timber Press, Oregon, USA. The shrub was first described and named by Yamazaki in 1971.Yamazaki, T. (1971) ''Journ. Jap. Bot.'' 46: 49. 1971. Description ''Buddleja bhutanica'' is a deciduous shrub 1.5–2 m in height, very similar to ''B. asiatica'' but distinguished by its perfoliate leaves. The branchlets are terete and glabrous, bearing opposite leaves, connate-perfoliate and narrowly oblong, 6–16 cm long by 3–8 cm wide, glabrous above and below, the margins serrate or entire. The white, very fragrant inflorescences comprise terminal panicle A panicle is a much-branched inflorescence. (softcover ). Some authors distinguish it from a compound spike inflorescence, by requiring that the flowers (and fruit) be pedicellate (hav ...

Inflorescence
An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Morphologically, it is the modified part of the shoot of seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the 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. The stem holding the whole inflorescence is called a peduncle. The major axis (incorrectly referred to as the main stem) above the peduncle bearing the flowers or secondary branches is called the rachis. The stalk of each flower in the inflorescence is called a pedicel. A flower that is not part of an inflorescence is called a solitary flower and its stalk is al ...

Hardiness Zone
A hardiness zone is a geographic area defined as having a certain average annual minimum temperature, a factor relevant to the survival of many plants. In some systems other statistics are included in the calculations. The original and most widely used system, developed by the United States Department of Agriculture (USDA) as a rough guide for landscaping and gardening, defines 13 zones by long-term average annual extreme minimum temperatures. It has been adapted by and to other countries (such as Canada) in various forms. Unless otherwise specified, in American contexts "hardiness zone" or simply "zone" usually refers to the USDA scale. For example, a plant may be described as "hardy to zone 10": this means that the plant can withstand a minimum temperature of 30 °F (−1.1 °C) to 40 °F (4.4 °C). Other hardiness rating schemes have been developed as well, such as the UK Royal Horticultural Society and US Sunset Western Garden Book systems. A heat zone (s ...

Teignmouth Orangery
Teignmouth ( ) is a seaside town, fishing port and civil parish in the English county of Devon. It is situated on the north bank of the estuary mouth of the River Teign, about 12 miles south of Exeter. The town had a population of 14,749 at the last census in 2011. From the 1800s onwards, the town rapidly grew in size from a fishing port associated with the Newfoundland cod industry to a fashionable resort of some note in Georgian times, with further expansion after the opening of the South Devon Railway in 1846. Today, its port still operates and the town remains a popular seaside and day trip holiday location. History To 1700 The first record of Teignmouth, ''Tengemuða'', meaning ''mouth of the stream'', was in 1044. Nonetheless, settlements very close by are attested earlier, with the banks of the Teign estuary having been in Saxon hands since at least 682, a battle between the Ancient Britons and Saxons being recorded on Haldon in 927, and Danish raids having o ...

Chelsea Physic Garden
The Chelsea Physic Garden was established as the Apothecaries' Garden in London, England, in 1673 by the Worshipful Society of Apothecaries to grow plants to be used as medicines. This four acre physic garden, the term here referring to the science of healing, is among the oldest botanical gardens in Britain, after the University of Oxford Botanic Garden. Its rock garden is the oldest in Europe devoted to alpine plants and Mediterranean plants. The largest fruiting olive tree in Britain is there, protected by the garden's heat-trapping high brick walls, along with what is doubtless the world's northernmost grapefruit growing outdoors. Jealously guarded during the tenure of the Worshipful Society of Apothecaries, the garden became a registered charity in 1983 and was opened to the general public for the first time. The garden is a member of the London Museums of Health & Medicine. It is also Grade I listed in the Register of Historic Parks and Gardens of Special Historic Intere ...

Corolla (flower)
Petals are modified leaves that surround the reproductive parts of flowers. They are often brightly colored or unusually shaped to attract pollinators. All of the petals of a flower are collectively known as the ''corolla''. Petals are usually accompanied by another set of modified leaves called sepals, that collectively form the ''calyx'' and lie just beneath the corolla. The calyx and the corolla together make up the perianth, the non-reproductive portion of a flower. When the petals and sepals of a flower are difficult to distinguish, they are collectively called tepals. Examples of plants in which the term ''tepal'' is appropriate include genera such as '' Aloe'' and ''Tulipa''. Conversely, genera such as ''Rosa'' and '' Phaseolus'' have well-distinguished sepals and petals. When the undifferentiated tepals resemble petals, they are referred to as "petaloid", as in petaloid monocots, orders of monocots with brightly colored tepals. Since they include Liliales, an alternative ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Panicle
A panicle is a much-branched inflorescence. (softcover ). Some authors distinguish it from a compound spike inflorescence, by requiring that the flowers (and fruit) be pedicellate (having a single stem per flower). The branches of a panicle are often racemes. A panicle may have determinate or indeterminate growth. This type of inflorescence is largely characteristic of grasses such as oat and crabgrass, as well as other plants such as pistachio and mamoncillo. Botanists use the term paniculate in two ways: "having a true panicle inflorescence" as well as "having an inflorescence with the form but not necessarily the structure of a panicle". Corymb A corymb may have a paniculate branching structure, with the lower flowers having longer pedicels than the upper, thus giving a flattish top superficially resembling an umbel. Many species in the subfamily Amygdaloideae, such as hawthorns and rowans, produce their flowers in corymbs. up'' Sorbus glabrescens'' corymb with fruit See ...

Leaf Shape
The following is a list of terms which are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (a single leaf blade or lamina) or compound (with several leaflets). The edge of the leaf may be regular or irregular, may be smooth or bearing hair, bristles or spines. For more terms describing other aspects of leaves besides their overall morphology see the leaf article. The terms listed here all are supported by technical and professional usage, but they cannot be represented as mandatory or undebatable; readers must use their judgement. Authors often use terms arbitrarily, or coin them to taste, possibly in ignorance of established terms, and it is not always clear whether because of ignorance, or personal preference, or because usages change with time or context, or because of variation between specimens, even specimens from the same plant. For example, whether to call leaves on the same tree "acuminate", "lanceolate", or "linear" could ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemicity
In epidemiology, an infection is said to be endemic in a specific population or populated place when that infection is constantly maintained at a baseline level without extra infections being brought into the group as a result of travel or similar means. An endemic disease always has a steady, predictable number of people getting sick, but that number can be high (''hyperendemic'') or low (''hypoendemic''), and the disease can be severe or mild. Also, a disease that is usually endemic can become epidemic. For example, chickenpox is endemic (steady state) in the United Kingdom, but malaria is not. Every year, there are a few cases of malaria reported in the UK, but these do not lead to sustained transmission in the population due to the lack of a suitable vector (mosquitoes of the genus ''Anopheles''). Consequently, the number of people infected by malaria is too variable to be called endemic. However, the number of people who get chickenpox in the UK varies little from year t ...

Glabrousness
Glabrousness (from the Latin ''glaber'' meaning "bald", "hairless", "shaved", "smooth") is the technical term for a lack of hair, down, setae, trichomes or other such covering. A glabrous surface may be a natural characteristic of all or part of a plant or animal, or be due to loss because of a physical condition, such as alopecia universalis in humans, which causes hair to fall out or not regrow. In botany Glabrousness or otherwise, of leaves, stems, and fruit is a feature commonly mentioned in plant keys; in botany and mycology, a ''glabrous'' morphological feature is one that is smooth and may be glossy. It has no bristles or hair-like structures such as trichomes. In anything like the zoological sense, no plants or fungi have hair or wool, although some structures may resemble such materials. The term "glabrous" strictly applies only to features that lack trichomes at all times. When an organ bears trichomes at first, but loses them with age, the term used is ''glabresce ...
