Theca
In biology, a theca (plural thecae) is a sheath or a covering. Botany In botany, the theca is related to plant's flower anatomy. The theca of an angiosperm consists of a pair of microsporangia that are adjacent to each other and share a common area of dehiscence called the stomium. Larry Hufford, "The origin and early evolution of angiosperm stamens" i''The Anther: form, function, and phylogeny'' William G. D'Arcy and Richard C. Keating (editors), Cambridge University Press, 1996, 351pp, p.60, (from Google Books) Any part of a microsporophyll that bears microsporangia is called an anther. Most anthers are formed on the apex of a filament. An anther and its filament together form a typical (or filantherous) stamen, part of the male floral organ. The typical anther is bilocular, i.e. it consists of two thecae. Each theca contains two microsporangia, also known as pollen sacs. The microsporangia produce the microspores, which for seed plants are known as pollen grains. If t ...

List Of Taxa Named By Anagrams
In the biological nomenclature codes, an anagram can be used to name a new taxon. Wordplays are one source of inspiration allowing organisms to receive scientific names. In the binomial nomenclature, as scientists have latitude in naming genera and species, a taxon name can therefore be an anagram, provided it remains pronounceable. For example, in the ''International Code of Nomenclature for algae, fungi, and plants'', a new generic name can be taken from the name of a person by using an anagram or abbreviation of it. William Elford Leach was among the first naturalists to use taxonomic anagrams, and, in 1818, he described several isopod genera that were each other's anagrams of 'Caroline' : '' Conilera'', '' Lironeca'', '' Nerocila'', '' Olencira'', and ''Rocinela ''Rocinela'' is a genus of isopods in the family Aegidae, and was first described in 1818 by William Elford Leach.Bruce, Niel L.; Schotte, M.

Orobanchaceae Genera
Orobanchaceae, the broomrapes, is a family of mostly parasitic plants of the order Lamiales, with about 90 genera and more than 2000 species. Many of these genera (e.g., '' Pedicularis'', '' Rhinanthus'', '' Striga'') were formerly included in the family Scrophulariaceae '' sensu lato''. With its new circumscription, Orobanchaceae forms a distinct, monophyletic family. From a phylogenetic perspective, it is defined as the largest crown clade containing ''Orobanche major'' and relatives, but neither '' Paulownia tomentosa'' nor '' Phryma leptostachya'' nor ''Mazus japonicus''. The Orobanchaceae are annual herbs or perennial herbs or shrubs, and most (all except '' Lindenbergia'', '' Rehmannia'' and '' Triaenophora'') are parasitic on the roots of other plants—either holoparasitic or hemiparasitic (fully or partly parasitic). The holoparasitic species lack chlorophyll and therefore cannot perform photosynthesis. Description Orobanchaceae is the largest of the ...

Hemiparasitic
A parasitic plant is a plant that derives some or all of its nutritional requirements from another living plant. They make up about 1% of angiosperms and are found in almost every biome. All parasitic plants develop a specialized organ called the haustorium, which penetrates the host plant, connecting them to the host vasculature – either the xylem, phloem, or both. For example, plants like '' Striga'' or '' Rhinanthus'' connect only to the xylem, via xylem bridges (xylem-feeding). Alternately, plants like '' Cuscuta'' and some members of '' Orobanche'' connect to both the xylem and phloem of the host. This provides them with the ability to extract water and nutrients from the host. Parasitic plants are classified depending on the location where the parasitic plant latches onto the host (root or stem), the amount of nutrients it requires, and their photosynthetic capability. Some parasitic plants can locate their host plants by detecting volatile chemicals in the air ...

George Bentham
George Bentham (22 September 1800 – 10 September 1884) was an English botanist, described by the weed botanist Duane Isely as "the premier systematic botanist of the nineteenth century". Born into a distinguished family, he initially studied law, but had a fascination with botany from an early age, which he soon pursued, becoming president of the Linnaean Society in 1861, and a fellow of the Royal Society in 1862. He was the author of a number of important botanical works, particularly flora. He is best known for his taxonomic classification of plants in collaboration with Joseph Dalton Hooker, his ''Genera Plantarum'' (1862–1883). He died in London in 1884. Life Bentham was born in Stoke, Plymouth, on 22 September 1800.Jean-Jacques Amigo, « Bentham (George) », in Nouveau Dictionnaire de biographies roussillonnaises, vol. 3 Sciences de la Vie et de la Terre, Perpignan, Publications de l'olivier, 2017, 915 p.
