Catalpa, commonly called catalpa or catawba, is a genus of flowering plants in the family Bignoniaceae, native to warm temperate and subtropical regions of North America, the Caribbean, and East Asia.
Swedish heraldry encompasses heraldic achievements in modern and historic Sweden.
 Swedish heraldic style is consistent with the German-Nordic heraldic tradition, noted for its multiple helmets and crests which are treated as inseparable from the shield, its repetition of colours and charges between the shield and the crest, and its scant use of heraldic furs. Because the medieval history of the Nordic countries was so closely related, their heraldic individuality developed rather late.
 Swedish and Finnish heraldry have a shared history prior to the Diet of Porvoo in 1809; these, together with Danish heraldry, were heavily influenced by German heraldry.
 Unlike the highly stylized and macaronic language of English blazon, Swedish heraldry is described in plain language, using (in most cases) only Swedish terminology.
Chainmail is a medieval miniature wargame created by Gary Gygax and Jeff Perren.
 Gygax developed the core medieval system of the game by expanding on rules authored by his fellow Lake Geneva Tactical Studies Association (LGTSA) member Perren, a hobby-shop owner with whom he had become friendly.
 Guidon Games released the first edition of "Chainmail" in 1971 as its first miniature wargame and one of its three debut products.
 "Chainmail" was the first game designed by Gygax that was available for sale as a professional product.
 It included a heavily Tolkien-influenced "Fantasy Supplement", which made "Chainmail" the first commercially available set of rules for fantasy wargaming, though it follows many hobbyist efforts from the previous decade. "
Dungeons & Dragons" began as a "Chainmail" variant, and "Chainmail" pioneered many concepts later used in "Dungeons & Dragons", including armor class and levels, as well as various spells, monsters and magical powers.
The Military Museum (Serbian Latin:"Vojni muzej" ) in Belgrade was founded in 1878.
 The museum has over 3000 ancient and modern items.
 These include Roman swords and helmets, Greek helmets and daggers, Serbian heavy knight's armor, axes, shields, helmets, crossbows, armoured gloves, as well as Western medieval weapons.
 There are also more modern guns, firearms, and elements of soldier's uniforms and equipment.
 Dioramas, plaques, and displays illustrate the use and historical context of the museum's collection.
Gerald Clough Dunning (20 December 1905 – 16 April 1978) was a pioneering scholar in the development of medieval British archaeology.
 His most significant contribution was in the study of post-Conquest pottery; he was largely responsible for establishing the first chronological framework by which different types of English ceramics could be dated.
 His work has been described as 'visionary' and 'seminal'.
 It has been noted that Dunning didn't achieve the profile of some of his peers due to the fact that he didn't write a text-book on either medieval pottery in particular or on medieval archaeology in general, but concentrated on writing articles for academic journals and encouraged the research interests of others, however John Hurst argued that, '...we should regard Gerald Dunning as the main founding father of medieval archaeology as we know it today in the last quarter of the 20th Century'.
Jim Jumani Johansson (legally Jim Jumani Immanuel Masauko Kamuzu Banda) is a 40-year-old Malawian-Swedish man who claims to be the son of former Malawian President Hastings Kamuzu Banda.
 He changed his name to Jim Jumani Immanuel Masauko Kamuzu Banda.
 Johansson says that it was after Banda died in 1997 that 'some government officials' told him about who his father really was.
 Officially, Banda died childless and unmarried.
 His claim and resemblance to the former dictator opened up many unanswered questions about the legacy of Banda.
 Johansson became a celebrity overnight in Malawi owing to his uncanny resemblance to the former president and his measures to seek legal means of proving his identity.
 Malawians are divided on whether he is the true heir but the public is demanding a right to know as well.
 Focus Gwede, the head of Banda's Special Branch of Secret Police Services, came out in support of Johansson, claiming that Banda had three children in 2010.
True miniature art or painting in little is a genre that focuses on art (especially painting, engraving and sculpture) with a long history that dates back to the scribes of the medieval ages.
 Miniature art societies, such as the World Federation of Miniaturists (WFM), provide applicable definitions of the term.
 An often-used definition is that a piece of miniature art can be held in the palm of the hand, or that it covers less than 25 square inches or 100 cm².
 Subjects are depicted in 1/6 actual size, and in all paintings the spirit of miniaturisation should be maintained.
The history of underwater diving starts with freediving as a widespread means of hunting and gathering, both for food and other valuable resources such as pearls and coral, By classical Greek and Roman times commercial applications such as sponge diving and marine salvage were established, Military diving also has a long history, going back at least as far as the Peloponnesian War, with recreational and sporting applications being a recent development.
 Technological development in ambient pressure diving started with stone weights (skandalopetra) for fast descent.
 In the 16th and 17th centuries diving bells became functionally useful when a renewable supply of air could be provided to the diver at depth, and progressed to surface supplied diving helmets - in effect miniature diving bells covering the diver's head and supplied with compressed air by manually operated pumps - which were improved by attaching a waterproof suit to the helmet and in the early 19th century became the standard diving dress.
A visor was used in conjunction with some Medieval war helmets such as the bascinet.
 The visor usually consisted of a hinged piece of steel that contained openings for breathing ("breaths") and vision.
 Visors protected the face during battle.
 Most knights or warriors who wore visors usually were spotted on horses during war, and more specifically in tournaments.
 The word "beaver" is sometimes used interchangeably with "visor", as in Shakespeare's "Hamlet", when Hamlet and Horatio are discussing the Ghost.
 Hamlet says: "Then saw you not his face?"
 to which Horatio responds "O yes, my lord.
 He wore his beaver up [i.e., his visor raised]".
Scutellaria is a genus of flowering plants in the mint family, Lamiaceae.
 They are known commonly as skullcaps.
 The generic name is derived from the Latin "scutella", meaning "a small dish, tray or platter", or "little dish", referring to the shape of the calyx.
 The common name alludes to the resemblance of the same structure to "miniature medieval helmets".
 The genus has a subcosmopolitan distribution, with species occurring nearly worldwide, mainly in temperate regions.

Question: Is Scutellaria or Catalpa know for its resemblance to miniature medieval helmets? 
Answer: Scutellaria
