Gomphoneis is a genus of diatoms in the family Gomphonemataceae.
The Oxalidaceae, or wood sorrel family, are a small family of five genera of herbaceous plants, shrubs and small trees, with the great majority of the 570 species in the genus Oxalis. Members of this family typically have divided leaves, the leaflets showing "sleep movements", spreading open in light and closing in darkness.
Begoniaceae is a family of flowering plants with two genera and about 2040 species occurring in the subtropics and tropics of both the New World and Old World. All but one of the species are in the genus Begonia. There have been many recent discoveries of species in the genus Begonia, such as Begonia truncatifolia which is endemic to San Vincente, Palawan. B. truncatifolia is smaller in size than other species of the genus Begonia and this new species is proposed Critically Endangered by standards set by the IUCN. The only other genus in the family, Hillebrandia, is endemic to the Hawaiian Islands and has a single species. Phylogenetic work supports Hillebrandia as the sister taxon to the rest of the family. The genus Symbegonia was reduced to a section of Begonia in 2003, as molecular phylogenies had shown it to be derived from within that genus. Members of the genus Begonia are well-known and popular houseplants.
In botany, a zoid or zoïd is a reproductive cell that possesses one or more flagella, and is capable of independent movement. Zoid can refer to either an asexually reproductive spore or a sexually reproductive gamete. In sexually reproductive gametes, zoids can be either male or female depending on the species. For example, some brown alga (Phaeophyceae) reproduce by producing multi-flagellated male and female gametes that recombine to form the diploid sporangia. Zoids are primarily found in some protists, diatoms, green alga, brown alga, non-vascular plants, and a few vascular plants. The most common classification group that produces zoids is the heterokonts or stramenopiles. These include green alga, brown alga, oomycetes, and some protists. The term is generally not used to describe motile, flagellated sperm found in animals. Zoid is also commonly confused for zooid which is a single organism that is part of a colonial animal.
The Coscinodiscophyceae are a class(s) of diatoms. They are similar to the Centrales, a traditional, paraphyletic subdivision of the heterokont algae known as diatoms. The order is named for the shape of the cell walls of centric diatoms, which are circular or ellipsoid in valve view. The valves often bear radially symmetrical ornamental patterns that can appear as dots when viewed with an optical microscope. Some also bear spines on their valves, which may either increase cell surface area and reduce sinking, or act as a deterrent to zooplankton grazers. Unlike pennate diatoms, centric diatoms never have a raphe.
Mastigias is a genus of true jellyfish in the family Mastigiidae. It contains seven described species. Members of this genus are found widely in coastal regions of the Indo-Pacific, including saline lakes of Palau, but there are also records from the West Atlantic at Florida and Puerto Rico. The West Atlantic records are most likely the result of accidental introductions by humans.
Kodaikanal Lake, also known as Kodai Lake, is a manmade lake located in the Kodaikanal city in Dindigul district in Tamil Nadu, India. Sir Vere Henry Levinge, the then Collector of Madurai, was instrumental in creating the lake in 1863, amidst the Kodaikanal town which was developed by the British and early missionaries from USA. The lake is said to be Kodaikanal's most popular geographic landmark and tourist attraction.
Phytotaxa is a peer-reviewed scientific journal for rapid publication on any aspect of systematic botany. It publishes on a wide range of subjects, but focuses on new species, monographs, floras, revisions, reviews, and typification issues. Phytotaxa covers all plant groups covered by the International Code of Nomenclature for algae, fungi, and plants, including diatoms, fungi, algae, lichens, mosses, hornworts, liverworts, and vascular plants), both living and fossil.
Euphronia is a genus of three species of shrubs native to northern South America and is the only genus in the family Euphroniaceae. It was previously classified in the Vochysiaceae family and elsewhere due to its unique floral features, but the APG III system of 2009 recognized Euphroniaceae as distinct and placed Euphronia in it. Based on molecular data from the rbcL gene, it is sister to the Chrysobalanaceae.
Naviculaceae is a diatom family in the order Naviculales.
Luticola desmetii is a species of non-marine diatom first found in lakes of James Ross Island.
Luticola doliiformis is a species of non-marine diatom first found in lakes of James Ross Island.
Luticola evkae is a species of non-marine diatom first found in lakes of James Ross Island.
Luticola permuticopsis is a species of non-marine diatom first found in lakes of James Ross Island.
Luticola tomsui is a species of non-marine diatom first found in lakes of James Ross Island.
Kewa is a genus of flowering plants, consisting of eight species of succulent sub-woody plants, native to eastern and southern Africa, including Saint Helena and Madagascar. These are small shrubs or herbs that form cushions and have edible, acid-tasting leaves. Kewa is the only genus in the family Kewaceae.
Cocconeis is a genus of diatoms. Members of the genus are elliptically shaped diatoms.
Surirella is a genus of diatoms in the family Surirellaceae.
Cyclotella is a genus of diatoms often found in oligotrophic environments, both marine and fresh water. It is in the family Stephanodiscaceae and the order Thalassiosirales. The genus was first discovered in the mid-1800s and since then has become an umbrella genus for nearly 100 different species, the most well-studied and the best known being Cyclotella meneghiniana. Despite being among the most dominant genera in low-productivity environments, it is relatively understudied.
Greta Albrecht Fryxell was a marine scientist known for her work on the biology and taxonomy of diatoms. In 1996, she was elected a fellow of the American Association for the Advancement of Science.
Nupela is a genus of diatom. Species of Nupela typically measure less than 20 µm. The genus was first described as being isovalvar, however many recently described species are heterovalvar. The main diagnostic characteristic of the genus is the presence of an external covering over the areolae. The genus was circumscribed by Wim Vyverman and Pierre Compère in 1991, with Nupela giluwensis asigned as the type, and at that time, only species.
