Helosciadium bermejoi, synonym Apium bermejoi, [2] is a critically endangered species of flowering plant in the family Apiaceae. [1]
Formerly included in the genus Apium , [3] genetic analysis showed it not to be closely related to the type species of that genus (wild celery Apium graveolens ), and it has now been transferred to the genus Helosciadium in the tribe Oenantheae. [4]
H. bermejoi is endemic to Menorca in the Balearic Islands of Spain, and the total population is now restricted to a single locality in the northeast part of the island. Across the two populations at this spot, there are fewer than a hundred individuals surviving. [1]
Its natural habitat is Mediterranean-type shrubby vegetation, known as matorral. [1]
It was classified as 'critically endangered' in the IUCN Red List in 2006. [1] In the European Union it has been designated as a 'priority species' under Annex II of the Habitats Directive since 1992, which means areas in which it occurs can be declared Special Areas of Conservation, if these areas belong to one of the number of habitats listed in Annex I of the directive.

Apium graveolens, known in English as wild celery, is an Old World species of flowering plant in the family Apiaceae. It was first described by Carl Linnaeus in 1753.
The conservation status of a group of organisms indicates whether the group still exists and how likely the group is to become extinct in the near future. Many factors are taken into account when assessing conservation status: not simply the number of individuals remaining, but the overall increase or decrease in the population over time, breeding success rates, and known threats. Various systems of conservation status are in use at international, multi-country, national and local levels, as well as for consumer use such as sustainable seafood advisory lists and certification. The two international systems are by the International Union for Conservation of Nature (IUCN) and The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).
Aiphanes is a genus of spiny palms which is native to tropical regions of South and Central America and the Caribbean. There are about 26 species in the genus, ranging in size from understorey shrubs with subterranean stems to subcanopy trees as tall as 20 metres (66 ft). Most have pinnately compound leaves ; one species has entire leaves. Stems, leaves and sometimes even the fruit are covered with spines. Plants flower repeatedly over the course of their lifespan and have separate male and female flowers, although these are borne together on the same inflorescence. Although records of pollinators are limited, most species appear to be pollinated by insects. The fruit are eaten by several birds and mammals, including at least two species of amazon parrots.
Apium is a genus, as currently circumscribed by Plants of the World Online, of 12 species of flowering plants in the family Apiaceae, with an unusual highly disjunct distribution with one species in the temperate Northern Hemisphere in the Western Palaearctic, and the rest in the temperate Southern Hemisphere in southern Africa, southern South America, Australia, and New Zealand. They are prostrate to medium-tall annual, biennial or perennial herbs growing up to 1 m high in wet soil, often marshes and salt marshes, and have pinnate to bipinnate leaves and small white flowers in compound umbels. Some species are edible, notably Apium graveolens, which is the wild ancestor of the commercially important vegetables celery, celeriac and leaf celery.
The Habitats Directive is a directive adopted by the European Community in 1992 as a response to the Berne Convention. The European Community was reformed as the European Union the following year, but the directive is still recognised.
An IUCN Red List Critically Endangered species is one that has been categorized by the International Union for Conservation of Nature as facing an extremely high risk of extinction in the wild. As of December 2023, of the 157,190 species currently on the IUCN Red List, 9,760 of those are listed as Critically Endangered, with 1,302 being possibly extinct and 67 possibly extinct in the wild.
Bupleurum kakiskalae is a species of flowering plant in the family Apiaceae. It is endemic to western Crete, an island which is part of Greece.
Naufraga balearica is an extremely rare species of flowering plant in the family Apiaceae, and the only species in the genus Naufraga. It is endemic to the Spanish island of Majorca, where it is found only at the base of cliffs at the north of the island near Pollença. A population was discovered on Corsica in 1981, but it had died out by 1983, and it is not clear whether it arrived naturally. Its natural habitats are Mediterranean-type shrubby vegetation and rocky shores.
Justicia flaviflora is a species of herbaceous plant in the family Acanthaceae. It was previously classified as Beloperone flaviflora. The species is endemic to the island of Trinidad in the Caribbean republic of Trinidad and Tobago where it is only known from near the peaks of mountains in the Northern Range. It is an erect herb with leaves up to 27 cm (11 in) long. It is suffering from habitat degradation and has become increasingly rare, being now rated as "critically endangered".
Potamogeton gramineus is a species of aquatic plant known by the common name various-leaved pondweed, variableleaf pondweed, grass-leaved pondweed or grassy pondweed, native to the northern hemisphere where it grows in shallow, clean water.
Helosciadium nodiflorum, fool's watercress, is a flowering plant found in ditches or streams, as well as fresh and brackish-water wetlands native to western Europe. It is not poisonous to humans but it could be easily confused with the allegedly poisonous lesser water parsnip.
Galium litorale is a rare species of bedstraw in the Rubiaceae family. It is endemic to the island of Sicily in the Mediterranean Sea. In Italian it is known as caglio costiero.
Narcissus nevadensis is a species of the genus Narcissus (daffodils) in the family Amaryllidaceae. It is classified in Section Nevadensis. It is native to the Baetic System in Spain. It is considered an endangered species. In 1992 it was designated as a 'priority species' under Annex II of the Habitats Directive in the European Union, which means areas in which it occurs can be declared Special Areas of Conservation, if these areas belong to one of the number of habitats listed in Annex I of the directive.
Centaurea horrida is a species of the genus Centaurea which is only found growing in Sardinia and associated islands. Due to their limited ability to disperse, they are isolated from other environments, and have a very low colonizing ability.
Daphne rodriguezii is a shrub, of the family Thymelaeaceae. It is endemic to Menorca, one of the Balearic Islands that belongs to Spain.
Helosciadium × longipedunculatum, synonym Apium × longipedunculatum, is a hybrid plant in the umbellifer family (Apiaceae); the result of hybridisation between Helosciadium repens and Helosciadium nodiflorum.
Betula chichibuensis, commonly known as Chichibu birch, is a species of birch native exclusively to limestone outcrops in the Okuchichibu and Kitakami Mountains of central and northeast Honshu, Japan. The tree is rated as Critically Endangered on the IUCN Red List due to its extreme rarity and limited range.
Hladnikia is a monotypic genus of flowering plants belonging to the family Apiaceae. Its sole species, Hladnikia pastinacifolia, is a Slovenian paleoendemite, restricted to the area of only 4 km2, located in Trnovo Forest Plateau, karst plateau of Western Slovenia. German botanist Heinrich Gottlieb Ludwig Reichenbach named the genus after Carniolan botanist and founder of Ljubljana Botanical Garden Franz Hladnik.
Helosciadium is a genus of flowering plants belonging to the family Apiaceae.
Helosciadium repens commonly known as creeping marshwort, is a species of plant belonging to the Apiaceae family. It occurs in Western and Central Europe, being rare throughout its range. It grows in wetland areas where it does not have to compete with taller plants due to grazing by animals, periodic flooding during the winter-spring seasons, or mowing. It is considered a species of near-threatened status at the continental level, critically endangered and legally protected in Poland. It is subject to protection within the European Natura 2000 network.
