Pulicaria dioscorides is a species of flowering plant in the family Asteraceae. It is found only on the island of Socotra in Yemen. Its natural habitat is rocky areas.
Pedanius Dioscorides, "the father of pharmacognosy", was a Greek physician, pharmacologist, botanist, and author of De materia medica, a 5-volume Greek encyclopedia about herbal medicine and related medicinal substances, that was widely read for more than 1,500 years. For almost two millennia Dioscorides was regarded as the most prominent writer on plants and plant drugs.
Hibiscus clayi, common names red Kauai rosemallow, Clay's hibiscus or Kokiʻo ʻula, is a perennial angiosperm of the mallow family Malvaceae. This species has unique leaves that are round and toothed and grow in a decussate pattern.
Acacia, commonly known as wattles or acacias, is a genus of about 1,084 species of shrubs and trees in the subfamily Mimosoideae of the pea family Fabaceae. Initially, it comprised a group of plant species native to Africa, South America, and Australasia, but is now reserved for species mainly from Australia, with others from New Guinea, Southeast Asia, and the Indian Ocean. The genus name is Neo-Latin, borrowed from the Greek ἀκακία, a term used in antiquity to describe a preparation extracted from Vachellia nilotica, the original type species.
Hibiscus dioscorides is a species of flowering plant in the family Malvaceae. It is found only in Yemen. Its natural habitat is rocky areas.
Ageratina rhypodes is a species of flowering plant in the family Asteraceae. It is found only in Ecuador. Its natural habitats are subtropical or tropical moist montane forests and subtropical or tropical high-altitude grassland. It is threatened by habitat loss.
Pulicaria aromatica is a species of flowering plant in the family Asteraceae. It is found only on the island of Socotra in Yemen. Its natural habitats are subtropical or tropical dry forests and rocky areas.
Pulicaria is a genus of flowering plant in the sunflower family, native to Europe, Asia, and Africa. In North America Pulicaria is known by the common name false fleabane.
Pulicaria diversifolia is a species of flowering plant in the family Asteraceae.It is found only on the islands of Socotra and Samhah in Yemen. Its natural habitat is rocky areas.
Pulicaria elegans is a species of flowering plant in the family Asteraceae. It is found only on the island of Socotra in Yemen. Its natural habitats are subtropical or tropical dry forests and subtropical or tropical dry shrubland.
Pulicaria lanata is a species of flowering plant in the family Asteraceae. It is found only on the island of Socotra in Yemen. Its natural habitat is subtropical or tropical dry shrubland.
Pulicaria stephanocarpa is a species of flowering plant in the family Asteraceae. It is endemic to Yemen's Socotra archipelago, where it is native to the islands of Socotra, Samhah, and Abd al Kuri. Its natural habitats are subtropical or tropical dry shrubland and rocky areas.
Pulicaria vieraeoides is a species of flowering plant in the family Asteraceae. It is endemic to the island of Socotra in Yemen. Its natural habitat is subtropical or tropical dry shrubland.
Hypericum balfourii is a species of flowering plant in the family Hypericaceae. It is endemic to Socotra, an island archipelago that is part of Yemen. It grows in mountain shrubland dominated by Cephalocroton. It is usually found on granite terrain above 600 meters in elevation.
Hypericum fieriense is a species of flowering plant in the St. John's wort family Hypericaceae. It is endemic to Socotra, an island archipelago that is part of Yemen. It grows in mountain shrubland dominated by Cephalocroton, where it can be found with the endemic tree Dracaena cinnabari. It is rarer than other local shrubby Hypericum species. It can be distinguished from them by its pubescent herbage.
Hypericum scopulorum is a species of flowering plant in the family Hypericaceae. It is endemic to Socotra, an island archipelago that is part of Yemen. It is a common plant in shrubland habitat, and it is a dominant species in some areas along with Cephalocroton and another local endemic, Libinhania rosulata.
Hypericum tortuosum is a species of flowering plant in the genus Hypericum. It is found only in Socotra, Yemen, where it is endemic. The species is an apomorphic relative of the other Socotran species in Hypericum sect. Triadenioides and is most closely related to Hypericum scopulorum. Its natural habitats are subtropical or tropical dry forests and subtropical or tropical dry shrubland.
Pulicaria dysenterica, the common fleabane, or, in North America, meadow false fleabane, is a species of fleabane in the family Asteraceae. It is native to Europe and western Asia where it grows in a variety of habitats ranging from semi-arid Mediterranean woodlands to wetter situations. Pulicaria dysenterica is perennial and can form dense clusters of plants, spreading by its roots. It flowers at its maximum height of about 60 centimetres (2.0 ft). Leaves are alternately arranged and clasp the stem, which itself contains a salty-astringent liquid. The yellow inflorescences are typically composed of a prominent centre of 40–100 disc florets surrounded by 20–30 narrow, pistillate ray florets. When setting seed the flower heads reflex.
Cissus subaphylla is a low shrub in the grape family Vitaceae. It is endemic to the Yemeni island of Socotra. The plant grows mainly in dry, low-lying areas on alluvial fans or on limestone slopes, and is rarely found above elevations of 300 metres (980 ft), where it is replaced by C. hamaderohensis. It does not have the climbing habit of other Cissus species, and its stems are flattened and gray-green in colour, with relatively small leaves and flowers. The tangled mats of C. subaphylla stems act as a protective covering for plants regularly eaten by goats and other browsing animals; the plant is thus important in the rehabilitation of species such as Dendrosicyos, Maerua and Commiphora.
Asphodelus aestivus, the summer asphodel, is a species of asphodel, a common Western Mediterranean geophyte with a short vertical rhizome and basal leaves. Its flowers are actinomorphic, pinkish-white, with six perianth segments, 14–19 mm long and six stamens of the same length, in two whorls. Its distribution is limited to the Western Mediterranean, mainly found in Portugal and Spain on the European mainland. There has been a lot of confusion over the nomenclature and taxonomy of the species, owing to its similarity to Asphodelus ramosus. It grows in dry grasslands, phrygana and on rocky or sandy ground.
Daphnia pulicaria is a species of freshwater crustaceans found within the genus of Daphnia, which are often called "water fleas," and they are commonly used as model organisms for scientific research. Like other species of Daphnia, they reproduce via cyclic parthenogenesis. D. pulicaria are filter-feeders with a diet primarily consisting of algae, including Ankistrodesmus falcatus, and they can be found in deep lakes located in temperate climates. Furthermore, D. pulicaria are ecologically important herbivorous zooplankton, which help control algal populations and are a source of food for some fish. D. pulicaria are closely related to Daphnia pulex, and numerous studies have investigated the nature and strength of this relationship because these species can produce Daphnia pulex-pulicaria hybrids. In recent years, D. pulicaria along with other Daphnia species have been negatively affected by invasive predators, such as Bythotrephes longimanus.
