Question: Which is native to more continents, Bursaria or Melissa?

Context paragraphs:
Bursaria: Bursaria is a genus of large shrubs and small trees which are native to Australia.  The genus was first described by Antonio Cavanilles in 1797, with his description of the type species "B. spinosa".  The name is derived from the Latin word "bursa" (purse) which relates to the shape of its seed capsules.

Panamanian cuisine: Panamanian cuisine is a mix of African, Spanish, and Native American techniques, dishes, and ingredients, reflecting its diverse population.  Since Panama is a land bridge between two continents, it has a large variety of tropical fruits, vegetables and herbs that are used in native cooking.

Denis Petukhov: Denis Alexandrovich Petukhov (Russian: Денис Александрович Петухов ; born October 6, 1978) is a Russian-American ice dancer.  With partner and wife Melissa Gregory, he is the 2005 Four Continents silver medalist, a 2006 United States Olympic team member, and a four-time (2004–07) U.S. national silver medalist.

Russian exploration of the Pacific Northwest: The Russian Empire began its interest of the Pacific Northwest in the 18th century, initially curious if there was a land connection between the Eurasian and North American Continents.  Two expeditions were led by Vitus Bering, with the findings proving the separation of two continents through the Bering Sea.  Being the first European nation to chart much of what comprises the modern American state of Alaska, many locations retain Russian place names.  The discovery of sizable fur bearing populations by Bering drew the attention of promyshlenniki previously engaged in the Siberian fur trade.  Based out of the Siberian ports of Okhotsk or Petropavlovsk, fur trappers sailed and reported the location of land formations like the Aleutian Islands, Kodiak Island and portions of the Alaskan mainland.  Relations with Native Alaskans was often terse due to the uncontrolled actions of particular promyshlenniki who killed and raped Indigenous on islands they trapped furs.

Conicosia pugioniformis: Conicosia pugioniformis is a species of succulent plant in the ice plant family known by the common names narrow-leaved iceplant and pigroot.  It is native to South Africa and it is known on other continents as an introduced species and sometimes a noxious weed.  It is an invasive species on the Central Coast of California, where it is a minor threat to native coastal vegetation, although not as harmful as other species of invasive iceplant.  This is a short-lived perennial herb growing from an underground caudex.  It can sprout vegetatively from the caudex if its aboveground parts are destroyed.  The fingerlike leaves are fleshy, gray-green, hairless, and up to 20 centimeters long.  The inflorescence is a solitary, malodorous flower up to 8 centimeters wide.  It has rings of up to 250 thin petals.

Melissa Gregory: Melissa Gregory (born May 22, 1981) is an American ice dancer.  With partner and husband Denis Petukhov, she is the 2005 Four Continents silver medalist, a 2006 United States Olympic team member, and a four-time (2004–07) U.S. national silver medalist.

European rabbit: The European rabbit or common rabbit ("Oryctolagus cuniculus") is a species of rabbit native to southwestern Europe (Spain, Portugal and Western France) and northwest Africa (Morocco and Algeria).  It has been widely introduced elsewhere, often with devastating effects on local biodiversity.  However, its decline in its native range (caused by the diseases myxomatosis and rabbit calicivirus, as well as overhunting and habitat loss), has caused the decline of its highly dependent predators, the Iberian lynx and the Spanish imperial eagle.  It is known as an invasive species because it has been introduced to countries on all continents with the exception of Antarctica, and caused many problems within the environment and ecosystems.  Australia has the most problems with European rabbits, due to the lack of natural predators there.

Alexander Lychnus: Alexander (Gr.  Ἀλέξανδρος ) surnamed Lychnus (Λύχνος ), was an ancient Greek rhetorician and poet.  He was a native of Ephesus, from which he is sometimes called Alexander Ephesius, and must have lived shortly before the time of Strabo (i.e., the 1st century BC), who mentions him among the more recent Ephesian authors, and also states that he took a part in the political affairs of his native city.  Strabo ascribes to him a history, and poems of a didactic kind, viz.  one on astronomy and another on geography, in which he describes the great continents of the world, treating of each in a separate work or book, which, as we learn from other sources, bore the name of the continent of which it contained an account.  What kind of history it was that Strabo alludes to, is uncertain.  The so-called Aurelius Victor quotes the first book of a history of the Marsic War by Alexander the Ephesian; but this authority is considered doubtful.

Melissa (plant): Melissa is a genus of perennial herbs in the Lamiaceae, native to Europe and Asia but cultivated and naturalized in many other places.  The name "Melissa" is derived from the Greek word "mélissa" meaning "honeybee", owing to the abundance of nectar in the flowers.  The stems are square, like most other plants in the mint family.  The leaves are borne in opposite pairs on the stems, and are usually ovate or heart-shaped and emit a lemony scent when bruised.  Axillary spikes of white or yellowish flowers appear in the summer.

Native Tour: The Native Tour (also known as the Native Summer Tour in North America or Native Fall Tour in Europe) is the third headlining concert tour by American pop-rock band, OneRepublic in support of their third studio album, "Native" (2013).  OneRepublic were joined on the Native Summer leg of the tour by, The Script and American Authors, and on the European "Native Fall Tour" leg by Kongos.  The tour has traveled across five continents; Asia, Europe, Oceania, North America, and Africa.  The tour began on April 2, 2013, in Milan, Italy and finished on September 20, 2015, in São Paulo, Brazil.
