The Rugosa, also called the Tetracoralla, are an extinct order of coral that were abundant in Middle Ordovician to Late Permian seas.
Solitary rugosans (e.g., Caninia, Lophophyllidium, Neozaphrentis, Streptelasma) are often referred to as horn corals because of a unique horn-shaped chamber with a wrinkled, or rugose, wall. Some solitary rugosans reached nearly a meter in length. However, some species of rugose corals could form large colonies (e.g., Lithostrotion). When radiating septa were present, they were usually in multiples of four, hence Tetracoralla in contrast to modern Hexacoralla, colonial polyps generally with sixfold symmetry.
Rugose corals have a skeleton made of calcite that is often fossilized. Like modern corals (Scleractinia), rugose corals were invariably benthic, living on the sea floor or in a reef-framework. Some symbiotic rugose corals were endobionts of Stromatoporoidea, especially in the Silurian. Although there is no direct proof, it is inferred that these Palaeozoic corals possessed stinging cells to capture prey. They also had tentacles to help them catch prey. Technically they were carnivores, but prey-size was so small they are often referred to as microcarnivores.
The Wych Elm cultivar Ulmus glabra 'Rugosa' was identified by Loudon in Arb. Frut. Brit. 3: 1898 as Ulmus montana (: glabra) var. rugosa Masters; another cultivar of the same name was earlier listed in Audibert's (Tonelle, Tarascon, France) catalogue of 1817 but without description.
Loudon described the tree as having "dark, reddish-brown bark, cracking into short, regular pieces, very like Acer campestre; a tree of spreading growth and moderate size." It was later described by Hartwig & Rümpler as having somewhat folded leaves, and being pyramidal, thick and bushy.
Only one specimen is known to survive, at Brighton, UK. 'Rugosa' is not known to have been introduced to North America or Australasia.
Ilex /ˈaɪlɛks/, or holly, is a genus of 400 to 600 species of flowering plants in the family Aquifoliaceae, and the only living genus in that family. The species are evergreen and deciduous trees, shrubs, and climbers from tropics to temperate zones worldwide.
The genus Ilex is widespread throughout the temperate and subtropical regions of the world. It includes species of trees, shrubs, and climbers, with evergreen or deciduous foliage and inconspicuous flowers. Its range was more extended in the Tertiary period and many species are adapted to laurel forest habitat. It occurs from sea level to more than 2,000 metres (6,600 ft) with high mountain species. It is a genus of small, evergreen trees with smooth, glabrous, or pubescent branchlets. The plants are generally slow-growing with some species growing to 25 m (82 ft) tall. The type species is the European holly Ilex aquifolium described by Linnaeus.
Plants in this genus have simple, alternate glossy leaves, typically with a spiny toothed, or serrated leaf margin. The inconspicuous flower is greenish white, with four petals. They are generally dioecious, with male and female flowers on different plants.
Ilex is the genus of flowering plants also known as holly.

The Chartered Institute of Legal Executives (CILEx) is the professional body for Chartered Legal Executives in England and Wales and an examination board providing qualifications for Chartered Legal Executives, paralegals and legal secretaries.
The Institute of Legal Executives as it stands was established in 1963 with the help of the Law Society of England and Wales to provide a more formal process for training so-called "solicitors' clerks". Prior to that the Institute had various incarnations dating back to 1892. Charles Dickens was a solicitor's clerk (he drew on his experience for characters in his novels, and a solicitor's managing clerk is featured in Galsworthy's Justice).
Traditionally, solicitors' clerks were not formally trained in law, but through experience had built up a working knowledge of specific aspects and could carry out legal paperwork as a fee earner. The creation of the Institute of Legal Executives meant that solicitors' clerks became qualified "legal executives" (holding a practising certificate and having a similar role to solicitors in practicing law). Legal Executive Lawyers gained rights that allow them to become partners in law firms, advocates with rights of audience in Court and also judges.
