Campylopus introflexus, the heath star moss, is a species of moss.
 It has a native southern hemisphere distribution in southern South America, southern part of Africa, southern and eastern Australia, and Atlantic and Pacific islands such as New Zealand, New Caledonia and the South Sandwich Islands.
 It is a neophyte in Europe and coastal western North America.
 In some parts of Europe and North America the species has become invasive.
 It can be found in a variety of settings, from bogs to dunes to flat roofs, often decalcified habitats.
 Individual plants measure 0.5 - , with lanceolate (lance-shaped) leaves 4 - .
 The plants are found in dense mats and are yellowish to olive green.
 This species will sometimes reproduce asexually by means of stem tips that break off and are distributed by the wind.
 Multiple sporophytes are often present in one plant.
 It produces spores of 12–14 µm in size.
Exochorda is a small genus of flowering plants in the family Rosaceae, native to China and central Asia (Turkestan).
 They are used as ornamental plants with the common name pearl bush, or pearlbush.
 Numerous species have been described on the basis of differing appearance and geographical separation, but a systematic study revealed that the different types are closely related and probably all descended from a single species that formerly had a wide distribution that has been fragmented by habitat loss.
 As a single species the correct name is "E. racemosa".
Lobelia deckenii (syn.
 "Lobelia keniensis") is a species of giant lobelia of the mountains of East Africa.
 It grows in moist areas, such as valley bottoms and moorland, in contrast to "Lobelia telekii" which grows in a similar, but drier habitat.
 These two species produce occasional hybrids.
 "Lobelia deckenii" plants usually produce multiple rosettes.
 Each rosette grows for several decades, produces a single large inflorescence and hundreds of thousands of seeds, then dies.
 Because individual plants have multiple rosettes, they survive to reproduce repeatedly, and plants with more rosettes flower more frequently.
 It is iteroparous.
Mosses are small flowerless plants that typically grow in dense green clumps or mats, often in damp or shady locations.
 The individual plants are usually composed of simple leaves that are generally only one cell thick, attached to a stem that may be branched or unbranched and has only a limited role in conducting water and nutrients.
 Although some species have conducting tissues, these are generally poorly developed and structurally different from similar tissue found in vascular plants.
 Mosses do not have seeds and after fertilisation develop sporophytes with unbranched stalks topped with single capsules containing spores.
 They are typically 0.2-10 cm tall, though some species are much larger.
 "Dawsonia", the tallest moss in the world, can grow to 50 cm in height.
Hand pollination, also known as mechanical pollination is a technique that can be used to pollinate plants when natural or open pollination is either undesirable or insufficient.
 This method of pollination is done by manually transferring pollen from the stamen of one plant to the pistil of another.
 This is often done with a cotton swab or small brush, but can also be done by removing the petals from a male flower and brushing it against the stigmas of female flowers, or by simply shaking flowers in the case of bisexual flowers, such as tomatoes.
 Common reasons for choosing this method include the lack of pollinators, keeping control of cross-pollination between varieties grown together, and creating specific hybrids.
 Examples of this are vanilla plants, which are transported to areas where its natural pollinator doesn't exist, or plants grown in greenhouses, urban areas, or with a cover to control pests, where natural pollinators cannot reach them.
 Pollinator decline and the concentrated pollination needs of monoculture can also be a factor.
 However, these are not the only reasons, and variable techniques for hand-pollination have arisen for many specialty crops.
 For instance, hand-pollination is used with date palms to avoid wasting space and energy growing sufficient male plants for adequate natural pollination.
 Because of the level of labor involved, hand-pollination is only an option on a small scale, used chiefly by small market gardeners and owners of individual plants.
 On large-scale operations, such as field crops, orchards, or commercial seed production, honeybees or other pollinators are a more efficient approach to pollination management.
 Despite this, hand-pollination is a fairly widespread practice.
 Pears grown in Hanyuan County, China have been hand-pollinated since the 1980s, because they can't be pollinated with other varieties that have different flowering times; also, lice infestation requires the use of many insecticide sprays, which causes local beekeepers to refuse to lend beehives.
Lobelia heterophylla is a blue to purple flowered herb found in Southern Australia.
 The specific epithet refers to the variety of leaf forms found on individual plants.
 The species was first described by Jacques Labillardière in his seminal work on Australian flora, "Novae Hollandiae Plantarum Specimen".
 "L. heterophylla" has a wide distribution, due to its ability to inhabit a variety of soil types.
 The habit of the herbaceous plant is erect, up to 0.6 metres, with flowers appearing from August or October to December, or January to February.
 The flower whorl is deeply cleft, its colour range of blue, scarlet or purple is well known and it is considered to be a desirable specimen for use in gardens.
 The plant is commonly referred to as wing-seeded lobelia and Australian blue creeper (various-leaved lobelia).
 The species was featured and illustrated by Joseph Paxton in 1838.
Cycadales is an order of seed plants that includes all the extant cycads.
 These plants typically have a stout and woody (ligneous) trunk with a crown of large, hard and stiff, evergreen leaves.
 They usually have pinnate leaves.
 The individual plants are either all male or all female (dioecious).
 Cycads vary in size from having trunks only a few centimeters to several meters tall.
 They typically grow very slowly and live very long, with some specimens known to be as much as 1,000 years old.
 Because of the superficial resemblance, they are sometimes confused with and mistaken for palms or ferns, but are only distantly related to either.
Diocirea is a genus of flowering plants in the figwort family, Scrophulariaceae.
 The genus is endemic to a small area in the south-west of Western Australia and is intermediate in character between "Eremophila" and "Myoporum".
 There are four members of the genus, all of which are small shrubs with stems and leaves which produce a resin making the plants appear bluish-green.
 Neither the genus, nor any of the species had been described before 2007 although a few specimens had been collected as "Eremophila elachantha".
 Despite their limited distribution, they often occur in populations of several thousand individual plants, forming a dense ground cover.
In agriculture, roguing refers to the act of identifying and removing plants with undesirable characteristics from agricultural fields.
 Rogues are removed from the fields to preserve the quality of the crop being grown.
 That is, the plants being removed may be diseased, be of an unwanted variety, or undesirable for other reasons.
 For example, to ensure that the crop retains its integrity with regards to certain physical attributes, such as color and shape, individual plants that exhibit differing traits are removed.
 Roguing is particularly important when growing seed crops to prevent plants with undesirable characteristics from propagating into subsequent generations.
A lime (from French "lime", from Arabic "līma", from Persian "līmū", "lemon") is a hybrid citrus fruit, which is typically round, lime green, 3 – in diameter, and contains acidic juice vesicles.
