Carex geminata is a tussock-forming species of perennial sedge in the family Cyperaceae. It is native to New Zealand. [1]
The Cyperaceae are a family of graminoid (grass-like), monocotyledonous flowering plants known as sedges. The family is large, with some 5,500 known species described in about 90 genera, the largest being the "true sedges" genus Carex with over 2,000 species.
Ornamental grasses are grasses grown as ornamental plants. Ornamental grasses are popular in many colder hardiness zones for their resilience to cold temperatures and aesthetic value throughout fall and winter seasons.
Cutty grass is a common name for several grasses with sharp leaves which may inflict cuts:
Didymosphenia geminata, commonly known as didymo or rock snot, is a species of diatom that produces nuisance growths in freshwater rivers and streams with consistently cold water temperatures and low nutrient levels. It is native to the northern hemisphere, and considered an invasive species in Australia, Argentina, New Zealand, and Chile. Even within its native range, it has taken on invasive characteristics since the 1980s. It is not considered a significant human health risk, but it can affect stream habitats and sources of food for fish and make recreational activities unpleasant. This microscopic alga can be spread in a single drop of water.
Carex is a vast genus of nearly 2,000 species of grass-like plants in the family Cyperaceae, commonly known as sedges. Other members of the family Cyperaceae are also called sedges, however those of genus Carex may be called true sedges, and it is the most species-rich genus in the family. The study of Carex is known as caricology.
Solenopsis geminata or tropical fire ant is a species of fire ants, described by Fabricius in 1804, in the tribe Solenopsidini; it was originally placed in the Atta genus. This species has a pan-tropical distribution.
Carex riparia, the greater pond sedge, is a species of sedge found across Europe and Asia. It grows in a variety of wet habitats, and can be a dominant species in some swamps. It is Britain's largest Carex, growing up to 130 cm tall, with glaucous leaves up to 160 cm long. It hybridises with a number of other Carex species, including the closely related Carex acutiformis – the lesser pond sedge. A variegated cultivar is grown as an ornamental grass.
Carex hirta, the hairy sedge or hammer sedge, is a species of sedge native across Europe. It has characteristic hairy leaves and inflorescences, and is the type species of the genus Carex.
Carex binervis, the green-ribbed sedge, is a European species of sedge with an Atlantic distribution. It is found from Fennoscandia to the Iberian Peninsula, and occurs in heaths, moorland and other damp, acidic environments. It typically grows to a height of 15–120 cm (6–50 in), and has inflorescences comprising one male and several female spikes, each up to 45 mm (1.8 in) long. The utricles have two conspicuous green veins, which give rise to both the scientific name and the common name of the species. In the vegetative state, it closely resembles C. bigelowii, a species that usually grows at higher altitude. C. binervis was first described by James Edward Smith in 1800, and is classified in Carex sect. Spirostachyae; several hybrids with other Carex species are known.
Quercus geminata, commonly called sand live oak, is an evergreen oak tree native to the coastal regions of the subtropical southeastern United States, along the Atlantic Coast from southern Florida northward to southeastern Virginia and along the Gulf Coast westward to southern Mississippi, on seacoast dunes and on white sands in evergreen oak scrubs.
Austroderia is a genus of five species of tall grasses native to New Zealand, commonly known as toetoe. The species are A. toetoe, A. fulvida, A. splendens, A. richardii and A. turbaria. They were recently reclassified in 2011 from the genus Cortaderia, although their distinctiveness had been recognized as early as 1853.
Carex sect. Ovales is a section of the genus Carex, containing around 85 species of sedge. It is the most diverse section of the genus in North America, containing 72 species:
Carex subg. Carex is a subgenus of the sedge genus Carex. It is the largest of the four traditionally recognised subgenera, containing around 1400 of the 2000 species in the genus. Its members are characterised by the presence of one or more exclusively male (staminate) terminal spikes, quite dissimilar in appearance from the lateral female (pistillate) spikes below. In most species, the female flowers have three stigmas, but a few species, including Carex nigra, have female flowers with only two stigmas.
Mattesia is a genus of parasitic alveolates of the phylum Apicomplexa. Species in this genus infect insects.
Carex subg. Vignea is a subgenus of the sedge genus Carex, containing around 300 of the 2000 species in the genus. Its members are characterised by having bisexual, sessile spikes, where the female flowers have two stigmas each.
Bradinopyga geminata is a species of dragonfly in the family Libellulidae known commonly as the granite ghost. It is native to India, Sri Lanka and Thailand, where it is a common and widespread species.
Gasteracantha geminata is a species of spider of the genus Gasteracantha, found in India and Sri Lanka. It is known as the oriental spiny orb-weaver.
Notoaeschna geminata is a species of dragonfly in the family Telephlebiidae, known as the northern riffle darner. It is endemic to eastern Australia, occurring north of the Hunter River, New South Wales, where it inhabits rapid streams.
