Drosera may refer to:
Drosera, commonly known as the sundews, is one of the largest genera of carnivorous plants, with at least 194 species. These members of the family Droseraceae lure, capture, and digest insects using stalked mucilaginous glands covering their leaf surfaces. The insects are used to supplement the poor mineral nutrition of the soil in which the plants grow. Various species, which vary greatly in size and form, are native to every continent except Antarctica.
Drosera is open source orienteering competition management software, which is part of orienteering toolbox. It is written as Java EE server with web interface and REST API for communication with other programs. It is built to use electronic punching system such as SPORTIdent.
In Greek mythology, Drosera was a naiad. She was one of the three ancestors of the Tyrians, along with Abarbarea and Callirrhoe. These nymphs were joined to sons of the soil (autochthonous) by the god Eros who was angered by their chastity.

Orienteering is a group of sports that require navigational skills using a map and compass to navigate from point to point in diverse and usually unfamiliar terrain whilst moving at speed. Participants are given a topographical map, usually a specially prepared orienteering map, which they use to find control points. Originally a training exercise in land navigation for military officers, orienteering has developed many variations. Among these, the oldest and the most popular is foot orienteering. For the purposes of this article, foot orienteering serves as a point of departure for discussion of all other variations, but almost any sport that involves racing against a clock and requires navigation with a map is a type of orienteering.
Drosera rotundifolia, the round-leaved sundew or common sundew, is a species of sundew, a carnivorous plant often found in bogs, marshes and fens. One of the most widespread sundew species, it has a circumboreal distribution, being found in all of northern Europe, much of Siberia, large parts of northern North America, Korea and Japan but is also found as far south as California, Mississippi and Alabama in the United States of America and on New Guinea.
Drosera regia, commonly known as the king sundew, is a carnivorous plant in the sundew genus Drosera that is endemic to a single valley in South Africa. The genus name Drosera comes from the Greek word droseros, meaning "dew-covered". The specific epithet regia is derived from the Latin for "royal", a reference to the "striking appearance" of the species. Individual leaves can reach 70 cm (28 in) in length. It has many unusual relict characteristics not found in most other Drosera species, including woody rhizomes, operculate pollen, and the lack of circinate vernation in scape growth. All of these factors, combined with molecular data from phylogenetic analysis, contribute to the evidence that D. regia possesses some of the most ancient characteristics within the genus. Some of these are shared with the related Venus flytrap (Dionaea muscipula), which suggests a close evolutionary relationship.
Drosera peltata, commonly called the shield sundew or pale sundew, is a climbing or scrambling perennial tuberous species in the carnivorous plant genus Drosera. Among the tuberous sundews, D. peltata has the largest distribution, which includes eastern and western Australia, New Zealand, India, and most of Southeast Asia including the Philippines. The specific epithet is Latin for "shield shaped", a reference to the shape of the cauline leaves. It is either a single extremely variable species, or a complex of several closely related species of uncertain taxonomic boundaries. In Australia at least four forms have had or still have specific taxonomic recognition: Drosera peltata subsp. peltata, D. peltata subsp. auriculata, D. foliosa and D. gracilis.
The International Orienteering Federation (IOF) is the international governing body of the sport of orienteering. The IOF head office is located in Karlstad, Sweden.
The World Orienteering Championships is an annual orienteering event organized by the International Orienteering Federation. The first World Championships was held in Fiskars, Finland in 1966. They were held biennially up to 2003. Since 2003, competitions have been held annually. Participating nations have to be members of the International Orienteering Federation (IOF).
The Carnivorous Plant Newsletter is the official publication of the International Carnivorous Plant Society (ICPS), the largest such organization in the world. It is headquartered in Walnut Creek, California.
The genus Drosera was divided in 1994 by Seine & Barthlott into three subgenera and 11 sections on the basis of morphological characteristics.
Drosera anglica, commonly known as the English sundew or great sundew, is a carnivorous plant species belonging to the sundew family Droseraceae. It is a temperate species with a generally circumboreal range, although it does occur as far south as Japan, southern Europe, and the island of Kauaʻi in Hawaiʻi, where it grows as a subtropical sundew. It is thought to originate from an amphidiploid hybrid of D. rotundifolia and D. linearis, meaning that a sterile hybrid between these two species doubled its chromosomes to produce fertile progeny which stabilized into the current D. anglica.
Ski orienteering (SkiO) is a cross-country skiing endurance winter racing sport and one of the four orienteering disciplines recognized by the IOF. A successful ski orienteer combines high physical endurance, strength and excellent technical skiing skills with the ability to navigate and make the best route choices while skiing at a high speed.
The World Ski Orienteering Championships (Ski-WOC) is the official event to award the titles of World Champions in ski orienteering. The World Championships is organized every odd year. The programme includes Sprint, Middle and Long Distance competitions, and a Relay for both men and women. The first Ski-WOC was held in 1975.
Drosera erythrorhiza, the red ink sundew, is a perennial tuberous species in the carnivorous plant genus Drosera that is endemic to Western Australia. It grows in a rosette and is distinguished from the other species in section Erythrorhiza by its many-flowered cymose inflorescences with up to 50 individual flowers. D. erythrorhiza was first described by John Lindley in his 1839 publication A sketch of the vegetation of the Swan River Colony. In 1992, N. G. Marchant and Allen Lowrie described three new subspecies, thus also creating the autonym D. erythrorhiza subsp. erythrorhiza. The subspecies were separated from this variable species mostly by leaf morphology and distribution.
The World Mountain Bike Orienteering Championships is the official event for awarding World Champion titles in mountain bike orienteering. The World Championships, also known as WMTBOC, were first held in 2002, and since 2004 they have been organized annually. The programme includes Long distance, Middle distance, Sprint, and a Relay for both men and women.
Drosera sect. Ergaleium is a section of 26 species that are erect or scrambling tuberous plants in the genus Drosera. This section represents a natural group and are taxonomically monophyletic.
The World Trail Orienteering Championships (WTOC) were first held in 2004 and annually since them. The majority of the championships were held in Europe, with 2005 the only exception up to date.
