Siphonia is a genus of extinct hallirhoid demosponges of the Lower and Upper Cretaceous, from about 125 to 66 million years ago. [1] They lived in the Western Tethys Ocean, in what is now Europe.
They all had distinctive pear-shaped bodies that were attached to the seafloor via a long stem. Their common name, "tulip sponges,"[ citation needed ] refers to their suggestive shape, while the genus name refers to how the spongocoel (the main tube of the sponge body) runs almost the entire length of the sponge, as though it were almost a drinking straw.
Sponges, the members of the phylum Porifera, are a basal animal clade as a sister of the diploblasts. They are multicellular organisms that have bodies full of pores and channels allowing water to circulate through them, consisting of jelly-like mesohyl sandwiched between two thin layers of cells.
1095 Tulipa is an Eos asteroid from the outer regions of the asteroid belt. It was discovered by German astronomer Karl Reinmuth at the Heidelberg-Königstuhl State Observatory in southwest Germany on 14 April 1926. The assumed S-type asteroid has a rotation period of 2.8 hours and measures approximately 30 kilometers in diameter. It was named after the flower Tulip. Originally, the name was redundantly assigned to Florian asteroid 1449 Virtanen.
Leucosolenia is a genus of calcareous sponges belonging to the family Leucosoleniidae. Species of this genus usually appear as groups of curved vases, up to 2 cm long, each ending in an osculum. The overall shape is sometimes likened to a tiny bunch of bananas. They are most often observed in tide pools, clustered around the base of seaweeds or on rocks, and occur in a variety of colours, usually rather pale. Its canal system is of asconoid type. The colony consists of few simple vase-like, cylindrical individuals each terminating in an osculum and united at their bases by irregular horizontal tubes. Leucosolenia reproduces both asexually and sexually. asexual reproduction by budding and sexual reproduction takes place by formation of gametes, i.e., ova and sperms. Lecosolenia is hermaphrodite, because both the gametes are formed in the body of same individual. Sponges are mostly asymmetrical, but Leucosolenia is symmetrical.
Tulipa clusiana, the lady tulip, is an Asian species of tulip native to Afghanistan, Iran, Iraq, Pakistan and the western Himalayas. It is widely cultivated as an ornamental and is reportedly naturalized in France, Spain, Portugal, Italy, Tunisia, Greece, and Turkey.
Tulipa gesneriana, the Didier's tulip or garden tulip, is a species of plant in the lily family, cultivated as an ornamental in many countries because of its large, showy flowers. This tall, late-blooming species has a single blooming flower and linear or broadly lanceolate leaves. This is a complex hybridized neo-species, and can also be called Tulipa × gesneriana. Most of the cultivars of tulip are derived from Tulipa gesneriana. It has become naturalised in parts of central and southern Europe and scattered locations in North America.
Tulips are spring-blooming perennial herbaceous bulbiferous geophytes in the Tulipa genus. Their flowers are usually large, showy, and brightly coloured, generally red, orange, pink, yellow, or white. They often have a different coloured blotch at the base of the tepals, internally. Because of a degree of variability within the populations and a long history of cultivation, classification has been complex and controversial. The tulip is a member of the lily family, Liliaceae, along with 14 other genera, where it is most closely related to Amana, Erythronium, and Gagea in the tribe Lilieae.
Trimastix is a genus of excavates, the sole occupant of the order Trimastigida. Trimastix are bacterivorous, free living and anaerobic. When first observed in 1881 by William Kent, the morphology of Trimastix was not well described but over time the oral structure and flagellar organization have become clearer. There are few known species, and the genus's role in the ecosystem is largely unknown. However, it is known that they generally live in marine environments within the tissues of decaying organisms to maintain an anoxic environment. Much interest in this group is related to its close association with other members of Anaeromonadea. These organisms do not have classical mitochondria, and as such, much of the research involving these microbes is aimed at investigating the evolution of mitochondria.
Spicules are structural elements found in most sponges. The meshing of many spicules serves as the sponge's skeleton and thus it provides structural support and potentially defense against predators.
Spongiforma is a genus of sponge-like fungi in the family Boletaceae. Newly described in 2009, the genus contains two species: S. thailandica and S. squarepantsii. The type species S. thailandica is known only from Khao Yai National Park in central Thailand, where it grows in soil in old-growth forests dominated by dipterocarp trees. The rubbery fruit bodies, which has a strong odour of coal-tar similar to Tricholoma sulphureum, consists of numerous internal cavities lined with spore-producing tissue. S. squarepantsii, described as new to science in 2011, is found in Malaysia. It produces sponge-like, rubbery orange fruit bodies with a fruity or musky odour. These fruit bodies will—like a sponge—resume their original shape if water is squeezed out. The origin of the specific name derives from its perceived resemblance to the cartoon character SpongeBob SquarePants. Apart from differences in distribution, S. squarepantsii differs from S. thailandica in its colour, odour, and spore structure.
Spongiforma squarepantsii is a species of fungus in the family Boletaceae, genus Spongiforma. Found in Malaysia, it was described as new to science in 2011. It produces sponge-like, rubbery orange fruit bodies that have a fruity or musky odour. The fruit bodies reach dimensions of 10 cm (3.9 in) wide by 7 cm (2.8 in) tall. Like a sponge, they will resume their original shape if water is squeezed out. The spores, produced on the surfaces of the hollows of the sponge, are almond-shaped with rough surfaces, and measure 10‑12.5 μm by 6‑7 μm. The name of the fungus derives from the Nickelodeon cartoon character SpongeBob SquarePants from the show of the same name. S. squarepantsii is one of two species in Spongiforma; it differs from S. thailandica in its color, odour, and spore structure.
Higginsia is a genus of sea sponges belonging to the order Axinellida.
Tulipa humilis is a species of flowering plant in the lily family, found in Syria, Lebanon, Israel, Turkey, Iran, and the North Caucasus region of Russia. The flowers are pink with yellow centers. Its preferred habitat are rocky mountain slopes. It is known by several other names in horticulture.
Tulipa linifolia, the flax-leaved tulip or Bokhara tulip, is a species of flowering plant in the tulip genus Tulipa, family Liliaceae, native to Tajikistan, Uzbekistan, northern Iran and Afghanistan. Growing to 20 cm (8 in) tall, it is a bulbous perennial with wavy red-margined sword-shaped leaves, and bowl-shaped red flowers in early to mid-spring. Each petal has blackish marks at the base.
Tulipa agenensis is a species of flowering plant in the family Liliaceae. It is native to Turkey, Iran, Cyprus, the Aegean Islands, Syria, Lebanon, Israel, Jordan, and naturalized in the central and western Mediterranean.
Tulipa sylvestris, the wild tulip or woodland tulip, is a Eurasian and North African species of wild tulip, a plant in the lily family. Its native range extends from Portugal and Morocco to western China, covering most of the Mediterranean and Black Sea Basins, and Central Asia. The species is also cultivated as an ornamental and naturalized in central and northern Europe as well as a few scattered locations in North America. It was first recorded as being naturalised in Britain in the late 17th century.
Thylacodes is a genus of sea snails, marine gastropod mollusks in the family Vermetidae, the worm snails or worm shells. The species in this genus were previously placed in the genus Serpulorbis.
Tulipa alberti, or Albert's tulip, is a species of flowering plant in the family Liliaceae. It has long reddish, orange or pink flowers. It comes from the mountains of Central Asia.
The taxonomy of Tulipa places the genus in the family Liliaceae, and subdivides it as four subgenera, and comprises about 75 species.
Tulipa fosteriana is a species of tulip, native to the Pamir Mountains and nearby areas of Afghanistan, Kyrgyzstan, Tajikistan and Uzbekistan.
