The "Tolkien Road" in Eastbourne, East Sussex, was named after Tolkien whereas the "Tolkien Way" in Stoke-on-Trent is named after Tolkien's eldest son, Fr. John Francis Tolkien, who was the priest in charge at the nearby Roman Catholic Church of Our Lady of the Angels and St. Peter in Chains. In the Hall Green and Moseley areas of Birmingham, parks and walkways are dedicated to J. R. R. Tolkien, especially at the Millstream Way and Moseley Bog. Collectively the parks are known as the Shire Country Parks. In Weston-super-Mare, Somerset, England there is a collection of roads in the 'Weston Village' named after locales of Middle Earth, namely Hobbiton Road, Bree Close, Arnor Close, Rivendell, Westmarch Way and Buckland Green.

About a dozen Tolkien-derived street names also appear scattered throughout the town of Lake Forest, California. The Columbia, Maryland, neighbourhood of Hobbit's Glen and its street names (including Rivendell Lane, Tooks Way, and Oakenshield Circle) come from Tolkien's works.

## Taxonomy

It has been noted that "Tolkien has been accorded formal taxonomic commemoration like no other author." In the field of taxonomy, over 200 taxa (genera and species) have been given scientific names honouring, or deriving from, characters or other fictional elements from The Lord of the Rings, The Hobbit, and other works set in Middle-earth.
Several taxa have been named after the character Gollum (also known as Sméagol), as well as for various hobbits, the small humanlike creatures such as Bilbo and Frodo Baggins. Various elves, dwarves, and other creatures that appear in his writings. Tolkien himself has been honoured in the names of several species. In 1978, paleontologist Leigh Van Valen named over 20 taxa of extinct mammals after Tolkien lore in a single paper. The entomologist Karl-Johan Hedqvist, also a fan of Tolkien, named several wasp genera after Tolkien's characters. In 1999, entomologist Lauri Kaila described 46 new species of Elachista moths and named 38 of them after Tolkien mythology.
In 2004, the extinct hominid Homo floresiensis was described, and quickly earned the nickname "hobbit" due to its small size.
    Pink background shading indicates that this species name has been synonymised and is no longer in use
