Bulbostylis neglecta, neglected tuft sedge locally, is an endemic member of the Cyperaceae of Saint Helena in the South Atlantic. [1] [2] [3]

Bulbostylis neglecta was first collected by William John Burchell in 1806, although the specimen was not described as a new species until 1884. [4] Since then, it had not been recorded again and was presumed extinct until, in May, 2008, during a botanical survey of St Helena, a small population of the sedge was rediscovered by botanists Philip Lambdon and Andrew Darlow of the European Union's South Atlantic Invasive Species Project and by local naturalist Pat Joshua. Subsequent work by the project team located five distinct populations totalling about 4000 plants. The rediscovery is timely as the existing populations are being encroached on by an invasive African fountain grass Pennisetum setaceum . [5] [6] [7]

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.

<span class="mw-page-title-main">Saint Helena olive</span> Extinct species of flowering plant

The Saint Helena olive is an extinct species of flowering plant. It is the only member of the genus Nesiota. It was endemic to the island of Saint Helena in the South Atlantic Ocean. Despite its name, it is unrelated to the true olive, but is instead a member of the family Rhamnaceae, the family which contains buckthorns and jujube. The last remaining tree in the wild died in 1994, and the last remaining individual in cultivation died in December 2003, despite conservation efforts. It is thus a prime example of recent plant extinction. The Saint Helena olive belongs to the tribe Phyliceae, which are mostly endemic to Southern Africa.

<i>Trochetiopsis ebenus</i> Species of flowering plant

Trochetiopsis ebenus, the dwarf ebony or Saint Helena ebony, is a species of flowering plant that is endemic to the island of Saint Helena in the southern Atlantic Ocean. It is not related to the ebony of commerce, but is instead a member of the mallow family, Malvaceae. Saint Helena ebony is now critically endangered in the wild, being reduced to two wild individuals on a cliff, but old roots are sometimes found washed out of eroding slopes. These are collected on the island a used for inlay work, an important craft on Saint Helena. A related species, Trochetiopsis melanoxylon is now completely extinct.

<i>Anogramma ascensionis</i> Species of fern

Anogramma ascensionis, the Ascension Island parsley fern, is a species of fern in the family Pteridaceae that is endemic to Ascension Island, a volcanic island in the South Atlantic Ocean. It is one of eight putative species in the genus Anogramma. It was thought to have become extinct due to habitat loss, until four plants were found on the island in 2010. Over 60 specimens were then successfully cultivated at Royal Botanic Gardens, Kew and on Ascension Island. It is now classified as Critically Endangered.

<i>Fimbristylis</i> Genus of grass-like plants

Fimbristylis is a genus of sedges. A plant in this genus may be known commonly as a fimbry or fimbristyle. There are 200 to 300 species distributed worldwide. Several continents have native species but many species have been introduced to regions where they are not native. Some are considered weeds. These are typical sedges in appearance, with stiff, ridged stems and cone-shaped terminal panicles of spikelets. They are found in wet environments, and are most diverse in tropical and subtropical regions.

<i>Bulbostylis</i> Genus of grass-like plants

Bulbostylis is a genus of plants in the sedge family. They are sometimes called hairsedges. There are over 200 species of these clump-forming plants of dry grasslands and warm and tropical savannas worldwide. They have solid, rounded, grooved stems and long, thin basal leaves. They bear spikelets of flowers.

<i>Dulichium arundinaceum</i> Species of grass-like plant

Dulichium is a monotypic genus of sedge containing the single species Dulichium arundinaceum, which is known by the common name threeway sedge. This is an aquatic or semi-aquatic plant of the lakes, streams, and ponds of the United States and Canada It has a wide distribution across the two countries, though noticeably absent from the Dakotas and from the Southwestern Deserts.

<i>Kyllinga</i> Genus of grass-like plants

Kyllinga is genus of flowering plants in the sedge family known commonly as spikesedges. They are native to tropical and warm temperate areas of the world, especially tropical Africa. These sedges vary in morphology, growing to heights from 2.5 centimeters to a meter and sometimes lacking rhizomes. They are closely related to Cyperus species and sometimes treated as part of a more broadly circumscribed Cyperus.

<i>Ficinia</i> Genus of grass-like plants

Ficinia is a genus of tufted or rhizomatous sedges in the family Cyperaceae. There are around 70 recognised species in Africa, four species that occur in New Zealand and a single species Ficinia nodosa that occurs in Australia.

The South Atlantic Invasive Species Project is a three-year project funded under the European Union EDF 9. The purpose of the project is to increase the capacity of the UK's South Atlantic Overseas Territories to deal with invasive species issues. The territories involved are Saint Helena, Tristan da Cunha, South Georgia and the South Sandwich Islands, the Falkland Islands and Ascension Island. The project is managed by the Royal Society for the Protection of Birds (RSPB) on behalf of the partner governments. In addition to the partner governments, two NGOs: Falklands Conservation and the Saint Helena National Trust are key stakeholders.

<i>Bulbostylis capillaris</i> Species of grass-like plant

<i>Bulbostylis lichtensteiniana</i> Species of flowering plant in the sedge family Cyperaceae

Bulbostylis lichtensteiniana is a species of flowering plant in the sedge family, Cyperaceae, that is endemic to Saint Helena. Unlike other species native to Saint Helena, such as Bulbostylis neglecta, Bulbostylis lichtensteiniana does not show obvious signs of decline due to the spread of invasive plants. However, the lack of decline is partially attributed to Bulbostylis lichtensteiniana being the only endemic plant to have expanded into new anthropogenic habitats.
