A herbarium is a collection of preserved plant specimens and associated data used for scientific study.
The Field Elm cultivar Ulmus minor 'Umbraculifera' [:shade-giving] was originally cultivated in Iran, where it was widely planted as an ornamental and occasionally grew to a great size, being known there as 'Nalband' Persian: نعلبند [:the tree of the farriers]. Litvinov considered it a cultivar of a wild elm with a dense crown that he called U. densa, from the mountains of Turkestan, Ferghana, and Aksu. Non-rounded forms of 'Umbraculifera' are also found in Isfahan Province, Iran. Zielińksi in Flora Iranica considered it an U. minor cultivar.
The Laboulbeniales is an order of Fungi within the class Laboulbeniomycetes. They are also known by the colloquial name beetle hangers or labouls. The order includes around 2,325 species of obligate insect ectoparasites that produce cellular thalli from two-celled ascospores. Of the described Laboulbeniales, Weir and Hammond 1997 find 80% to be from Coleoptera and the next largest group to be the 10% from Diptera. Recently, the genus Herpomyces, traditionally considered a basal member of Laboulbeniales, was transferred to the order Herpomycetales based on molecular phylogenetic data. Laboulbeniales typically do not kill their hosts, although they may impair host fitness if the parasite density is high.
The so-called American Elm cultivar Ulmus americana 'Variegata' was a Belgian clone mentioned by Wesmael in Bulletin de la Fédération des sociétés d'horticulture de Belgique, 1862, as Ulmus americana var. variegataHort. It was marketed by the Baudriller nursery of Angers as U. americana foliis variegatis. Wesmael's herbarium specimens, however, held in the Botanic Garden, Meise, both of his Ulmus americana and of his Ulmus americana var. variegata, do not appear to show American white elm leaves. It is known that nurseries in Europe and America marketed the golden wych elm Ulmus glabra 'Lutescens' as Ulmus americana aurea, and it is likely that Wesmael's Ulmus americana variegata was similarly misnamed, and perhaps derived from a reverting branch of aurea, whose leaves it resembled.
The putative Wych Elm cultivar Ulmus glabra 'Dovaei', or Doué elm, was raised by the André Leroy nursery at Angers, France, as Ulmus dovaei, before 1868. The Baudriller nursery of Angers marketed it as Ulmus Dowei, "orme de Doué", suggesting a link with the royal nurseries at nearby Doué-la-Fontaine, which stocked elm. Green considered it a form of wych.
Hauteville-la-Guichard is a commune in the Manche department in Normandy in north-western France.
Ulmus × hollandica 'Klemmer', or Flanders Elm, is probably one of a number of hybrids arising from the crossing of Wych Elm with a variety of Field Elm, making it a variety of Ulmus × hollandica. Originating in the Bruges area, it was described by Gillekens in 1891 as l'orme champêtre des Flandres in a paper which noted its local name, klemmer, and its rapid growth in an 1878–91 trial. Kew, Henry (1913), and Krüssmann (1976) listed it as an Ulmus × hollandica cultivar, though Henry noted its "similarity in some respects" to field elm Ulmus minor, while Green went as far as to regard it as "possibly U. carpinifolia" (:minor).
The hybrid elm cultivar Ulmus × hollandica 'Tricolor' was first listed as U. suberosa tricolor by C. de Vos in 1867.
The Field Elm cultivar Ulmus minor 'Pendula' was said to have been raised in Belgium in 1863. It was listed as Ulmus sativa pendula by C. de Vos in 1887, and by Boom in 1959 as a cultivar.
Platanthera elegans is a species of orchid known by several common names, including elegant piperia, coast piperia, hillside rein orchid, and hillside bogorchid. This is a showy flowering plant native to western North America. It grows from a caudex tuber and sends up a thick stem just under a meter in maximum height. The stem is topped with a cylindrical spike inflorescence of densely packed flowers with curving white to greenish-yellow petals. Coastal individuals are noticeably thicker and have more flowers than those that grow further inland; it is uncertain if these are variants, subspecies, or even separate species. They are both currently treated as P. elegans. Other species of Plantanthera, notably the endangered species P. yadonii are quite similar in appearance to some populations of this species.
Rémelfing is a commune in the Moselle department in Grand Est in north-eastern France.
René Charles Joseph Ernest Maire was a French botanist and mycologist. His major work was the Flore de l'Afrique du Nord in 16 volumes published posthumously in 1953. He collected plants from Algeria, Morocco, France, and Mali for the herbarium of the National Botanic Garden of Belgium.

Cucujomyces is a genus of fungi in the family Laboulbeniaceae. The genus contain 14 species.
Peyerimhoffiella is a genus of fungi in the family Laboulbeniaceae. A monotypic genus, it contains the single species Peyerimhoffiella elegans.
Roland Thaxter was an American mycologist, plant pathologist, botanist, and entomologist, renowned for his contribution to the insect parasitic fungi—Laboulbeniales. His college education was completed at Harvard, where he dedicated forty years to mycological and botanical research. His five-volume series on fungi in the order Laboulbeniales laid a solid foundation of research on these insect ectoparasites. He also contributed to the field of Plant Pathology.
Cucujomyces elegans is a species of fungus in the family Laboulbeniaceae. It is found in Argentina.
The Field Elm cultivar Ulmus minor 'Viminalis Betulaefolia' (:'birch-leaved') is an elm tree of uncertain origin. An U. betulaefolia was listed by Loddiges of Hackney, London, in the catalogue of 1836, an U. campestris var. betulaefolia by Loudon in Arboretum et Fruticetum Britannicum (1838), and an U. betulifoliaBooth by the Lawson nursery of Edinburgh. Henry described an U. campestris var. betulaefolia at Kew in 1913, obtained from Fulham nurseryman Osborne in 1879, as "scarcely different from var. viminalis ". Melville considered the tree so named at Kew a form of his U. × viminalis, while Bean (1988), describing U. 'Betulaefolia', likewise placed it under U. 'Viminalis' as an apparently allied tree. Loudon and Browne had noted that some forms of 'Viminalis' can be mistaken for a variety of birch. An U. campestris betulaefolia was distributed by Hesse's Nurseries, Weener, Germany, in the 1930s.
Chitonomyces elegans is a species of fungus in the family Laboulbeniaceae.
Cryptandromyces elegans is a species of fungus in the family Laboulbeniaceae. It is found in the Netherlands.
