'Klemmer' or the Flanders Elm, is probably one of a number of hybrids arising from the crossing of the Wych Elm (Ulmus glabra) with a variety of Field Elm (Ulmus minor), making it a variety of Ulmus × hollandica . Originating in the Bruges area, it was released in 1789 and was listed at the Royal Botanic Gardens Kew as Ulmus × hollandica var. Klemmerii. The name 'Klemmer' derives, however, from the Flemish for 'climber', a reference to the tree's rapid growth and lofty height; so Klemmerii is a misnomer, incorrectly implying a proper noun Klemmer. This elm's rapid growth in its native area suggests F1 hybrid vigour. Though the tree was regarded by Green as "possibly U. carpinifolia (: minor)", fast growth is not usually a feature of U. minor in Northern Europe.

NB. The tree should not be confused with 'Klehmii', a cultivar of Ulmus americana named for Charles Klehm, an Illinois nurseryman.

A rapid growing tree, tall with ascending branches initially forming a narrow, pyramidal head which later broadens, and producing numerous root-suckers and some epicormic shoots. 'Klemmer' has a straight, cylindrical stem. The bark is smooth in young trees and later fissured. The leaves are ovate, up to 7.5 cm (3 in) long and up to 5.0 cm (2 in) broad, shortly acuminate at the apex, the upper surface scabrous and glabrescent. The samarae are distinguished by a seed situated close to the emargination. The timber is reddish in hue, strong but liable to warping.

Sherlock Holmes ( /ˈʃɜrlɒk ˈhoʊmz/) is a fictional detective created by Scottish author and physician Sir Arthur Conan Doyle. The fantastic London-based "consulting detective", Holmes is famous for his astute logical reasoning, his ability to adopt almost any disguise, and his use of forensic science skills to solve difficult cases.

Holmes, who first appeared in publication in 1887, was featured in four novels and 56 short stories. The first novel, A Study in Scarlet, appeared in Beeton's Christmas Annual in 1887 and the second, The Sign of the Four, in Lippincott's Monthly Magazine in 1890. The character grew tremendously in popularity with the first series of short stories in Strand Magazine, beginning with A Scandal in Bohemia in 1891; further series of short stories and two novels published in serial form appeared between then and 1927. The stories cover a period from around 1880 up to 1914.

All but four stories are narrated by Holmes's friend and biographer, Dr. John H. Watson; two are narrated by Holmes himself ("The Blanched Soldier" and "The Lion's Mane") and two others are written in the third person ("The Mazarin Stone" and "His Last Bow"). In two stories ("The Musgrave Ritual" and "The Gloria Scott"), Holmes tells Watson the main story from his memories, while Watson becomes the narrator of the frame story. The first and fourth novels, A Study in Scarlet and The Valley of Fear, each include a long interval of omniscient narration recounting events unknown to either Holmes or Watson.
