It was the first episode written by Linwood Boomer and was directed by Todd Holland. In the episode, the six primary characters are introduced, Malcolm, Lois, Hal, Reese, Dewey, and Francis, and Malcolm's struggles and fears to be placed in the accelerated learning class ('Krelboynes') even though he has an IQ of 165. Airing as a midseason replacement for Futurama, the episode gained a large viewer base, with ratings of 23 million.

Lothar Späth was a German politician of the CDU.

The putative Wych Elm cultivar Ulmus glabra 'Holgeri' originated in Sweden, where it was described by Holger Jensen of Ramlösa Plantskola, Helsingborg, in 1921. It was distributed by the Späth nursery of Berlin in the 1920s and '30s as Ulmus montana Holgeri. Späth used U. montana both for wych and for U. × hollandica hybrids like 'Dampieri', so the name does not necessarily imply a wych cultivar. In The Netherlands the tree was classified as an Ulmus × hollandica hybrid, a 1932 herbarium specimen from a tree in The Hague supplied by Späth being labelled Ulmus hollandica var. holgeri (Jensen).

The hybrid elm cultivar Ulmus × hollandica 'Tricolor' was first listed as U. suberosa tricolor by C. de Vos in 1867.

<i>Ulmus americana</i> Pendula Elm cultivar

The American elm cultivar Ulmus americana 'Pendula' was originally listed by William Aiton in Hort. Kew, 1: 320, 1789, as U. americana var. pendula, cloned in England in 1752 by James Gordon. From the 1880s the Späth nursery of Berlin supplied a cultivar at first listed as Ulmus fulva (Michx.) pendulaHort., which in their 1899 catalogue was queried as a possible variety of U. americana, and which thereafter appeared in their early 20th-century catalogues as U. americana pendula. The Scampston Elm, Ulmus × hollandica 'Scampstoniensis', in cultivation on both sides of the Atlantic in the 19th and 20th centuries, was occasionally referred to as 'American Weeping Elm' or Ulmus americana pendula. This cultivar, however, was distinguished by Späth from his Ulmus americana pendula.

<i>Ulmus minor</i> Umbraculifera Gracilis Elm cultivar

The Field Elm cultivar Ulmus minor 'Umbraculifera Gracilis' was obtained as a sport of 'Umbraculifera' by the Späth nursery of Berlin c.1897. It was marketed by the Späth nursery in the early 20th century, and by the Hesse Nursery of Weener, Germany, in the 1930s.

The Field Elm cultivar Ulmus minor 'Rugosa' was distributed by the Späth nursery, Berlin, in the 1890s and early 1900s as U. campestris rugosaKirchner. Kirchner's tree, like Späth's a level-branched suberose field elm, was received from Belgium in 1864 as Ulmus rugosa pendula. Kirchner stressed that it was different from Loudon's Ulmus montana var. rugosa, being "more likely to belong to U. campestris or its subspecies, the Cork-elm".

<i>Ulmus minor</i> Dicksonii Elm cultivar

The Field Elm cultivar Ulmus minor 'Dicksonii', commonly known as Dickson's Golden Elm, is a yellow-leaved tree raised in Chester in 1900 by Dickson's Nursery, which distributed it from the autumn of 1907 as 'Golden Cornish Elm'. 'Cornish Elm' was the name often given in error to Guernsey or Wheatley Elm by the local authorities who planted the latter extensively, an error which may have influenced the choice of name by Dickson's nursery. 'Dicksonii' is usually listed as a variety of Guernsey Elm rather than Cornish Elm, Bean giving 'Wheatleyi Aurea' as a synonym, and Hillier 'Sarniensis Aurea' and later U. × sarniensis 'Dicksonii'. Clibrans' nursery of Altrincham, however, described it (1922) as otherwise identical "in habit and constitution" to 'type' Cornish Elm. The Späth nursery of Berlin distributed it from c.1913 as U. campestris cornubiensis Dicksonii. The nursery Messieurs Otin père et fils of Saint-Étienne sold an Ulmus Wheatleyi aurea pyramidalis, with leaves marbled yellow, in 1882, earlier than Dickson's introduction.

Diplomoceratidae is a family of ammonites included in the order Ammonitida. Fossils of species within this genus have been found in the Cretaceous sediments. Studies of Diplomoceras suggest that members of this family could reach lifespans of over 200 years.

<i>Ulmus</i> Glabra Elm cultivar

The elm cultivar Ulmus 'Glabra' was distributed by the Späth nursery, Berlin, in the 1890s and early 1900s as U. glabraMill.. Not to be confused with the species U. glabraHuds..

<i>Ulmus minor</i> Monumentalis Elm cultivar

The Field Elm cultivar Ulmus minor 'Monumentalis', the tomb elm (Grabmal-Rüster), was raised as a sucker of U. suberosa by Sebastian Rinz, the city gardener of Frankfurt, before 1855 and listed by the Jacob-Makoy nursery of Liège in their 1861 catalogue as Ulmus monumentalisRinz, "a new variety". Kirchner (1864) described it, confirming that it had only recently been propagated by Rinz and established in the nursery. It was distributed from the 1880s by the Baudriller nursery, Angers, and by the Späth nursery, Berlin, as U. campestris monumentalisRinz., appearing separately in their catalogues from U. minor 'Sarniensis', the Guernsey or Wheatley Elm, with which, according to Henry, it was confused on the continent. Krüssmann, for example, gives 'Monumentalis' as a synonym of 'Sarniensis'. 'Sarniensis' is known as monumentaaliep [:monumental elm] in The Netherlands. Springer noted that the Dutch monumentaaliep was "not the actual monumentaaliep but U. glabraMill.var. Wheatleyi Sim. Louis", and that it "should be renamed U. glabraMill. var. monumentalisHort.(non Rinz)". In England, Smith's of Worcester listed Ulmus monumentalis separately from Ulmus 'Wheatley' in the 1880s.

The Wych Elm cultivar Ulmus glabra 'Gigantea' was listed as U. montana var. giganteaHort. by Kirchner (1864). An U. montana gigantea was distributed by the Späth nursery, Berlin, in the 1890s and early 1900s. It did not appear in Späth's 1903 catalogue. A specimen at Kew was judged by Henry to be "not distinct enough to deserve a special name". Both Späth and the Hesse Nursery of Weener, Germany, supplied it in the 1930s.

The elm cultivar Ulmus 'Betulaefolia Nigrescens', the Black Birch-leaved Elm, reportedly a seedling of a purplish-leaved elm, was first described by Pynaert in 1879 as U. campestris betulaefolia nigrescens. An U. campestris betulaefolia nigrescensHort. was distributed by the Späth nursery, Berlin, in the 1890s and early 1900s.

The hybrid elm cultivar Ulmus × hollandica 'Viminalis' [:osier-leaved] was listed by the Späth nursery of Berlin as Ulmus scabraMill. var. viminalis in 1890 and as Ulmus montana viminalis from 1892. Though Späth's catalogues stated that it was "also distributed under the name planera aquatica", it remained in his lists under 'elm' and was accessioned by the Dominion Arboretum, Ottawa, and by the Royal Botanic Garden Edinburgh as an elm cultivar. A similar misidentification occurred in the mid-20th century, when the Siberian elm cultivar Ulmus pumila 'Poort Bulten' was for many years commercially propagated under the name Planera aquatica or 'water elm'. As the leaves of osier or Salix viminalis, however, differ markedly from those of Planera aquatica, being long, thin and tapering at both ends, Spath's name 'Viminalis' for this elm cultivar confirms that its leaves were not Planera-like. The probable explanation for the early distribution name is that Planera was the old name for Zelkova, a close relative of elm with willow-like leaves. It is therefore unlikely that 'Viminalis' was related in any way to the 19th-century elm cultivar Ulmus 'Planeroides'.
