Question: Are Witch-hazel and Bikkia endemic to North America?
Context: Hamamelis virginiana, known as common or American witch-hazel, is a species of witch-hazel native to eastern North America, from Nova Scotia west to Minnesota, and south to central Florida to eastern Texas. Hamamelis vernalis (Ozark witchhazel) is a species of witch-hazel native to the Ozark Plateau in central North America, in Missouri, Oklahoma, and Arkansas. Witch-hazels ("Hamamelis," ) are a genus of flowering plants in the family Hamamelidaceae, with four species in North America ("H. mexicana", "H. ovalis", "H. virginiana", and "H. vernalis"), and one each in Japan ("H. japonica") and China ("H. mollis").  The North American species are occasionally called winterbloom. Dicerca pugionata is a species of buprestid beetle from the Chrysochroinae subfamily that occurs in the Eastern North America.  Its food includes witch-hazel species including "Hamamelis virginiana" in mid July.  It also feeds on ninebark and alder species. North American Atlantic Region is a floristic region within the Holarctic Kingdom identified by Armen Takhtajan and Robert F. Thorne, spanning from the Atlantic and Gulf coasts to the Great Plains and comprising a major part of the United States and southeastern portions of Canada.  It is bordered by the Circumboreal floristic region in the north, by the Rocky Mountain and Madrean floristic regions in the west and by the Caribbean floristic region of the Neotropical Kingdom in the south of Florida.  The flora of the region comprises two endemic monotypic families, Hydrastidaceae and Leitneriaceae, and is characterized by about a hundred of endemic genera (such as "Sanguinaria", "Leavenworthia", "Gillenia", "Neviusia", "Dionaea", "Yeatesia", "Pleea").  The degree of species endemism is very high, many species are Tertiary relicts, which survived the Wisconsin glaciation and are now concentrated in the Appalachians (esp.  Blue Ridge Mountains) and the Ozarks.  A number of genera ("Sarracenia", "Uvularia" etc.) are shared only with the Canadian floristic province of the Circumboreal region.  Moreover, as has long been noted (e.g. by Joseph Gerhard Zuccarini and especially by Asa Gray), a large number of relict genera ("Liriodendron", "Hamamelis", "Stewartia" etc.) are shared with the relatively distant Eastern Asiatic Region (comprising Japan and the east of China) and sometimes Southeast Asia.  R. F. Thorne counted at least 74 genera restricted to eastern North America and Asia (mostly eastern and southeastern Asia).  The fossil record indicates that during the Tertiary period a warm temperate zone extended across much of the Northern Hemisphere, linking America to Asia. The genus Arceuthobium, commonly called dwarf mistletoes, is a genus of 26 species of parasitic plants that parasitize members of Pinaceae and Cupressaceae in North America, Central America, Asia, Europe, and Africa.  Of the 42 species, 39 and 21 are endemic to North America and the United States, respectively.  They all have very reduced shoots and leaves (mostly reduced to scales) with the bulk of the plant living under the host's bark.  Recently the number of species within the genus has been reduced to 26 as a result of more detailed genetic analysis. Hesperia (the branded skippers) is a Holarctic genus in the skippers (Hesperiidae) butterfly family.  Most species are endemic to North America, "Hesperia comma" is widespread throughout the region.  "H. florinda" is endemic to temperate eastern Asia.  "H. nabokovi" is endemic to Hispaniola. Blastomyces dermatitidis is the causal agent of blastomycosis, an invasive and often serious fungal infection found occasionally in humans and other animals in regions where the fungus is endemic.  The causal organism is a fungus living in soil and wet, decaying wood, often in an area close to a waterway such as a lake, river or stream.  Indoor growth may also occur, for example, in accumulated debris in damp sheds or shacks.  The fungus is endemic to parts of eastern North America, particularly boreal northern Ontario, southeastern Manitoba, Quebec south of the St. Lawrence River, parts of the U.S. Appalachian mountains and interconnected eastern mountain chains, the west bank of Lake Michigan, the state of Wisconsin, and the entire Mississippi Valley including the valleys of some major tributaries such as the Ohio River.  In addition, it occurs rarely in Africa both north and south of the Sahara Desert, as well as in the Arabian Peninsula and the Indian subcontinent.  Though it has never been directly observed growing in nature, it is thought to grow there as a cottony white mold, similar to the growth seen in artificial culture at 25 C .  In an infected human or animal, however, it converts in growth form and becomes a large-celled budding yeast.  Blastomycosis is generally readily treatable with systemic antifungal drugs once it is correctly diagnosed; however, delayed diagnosis is very common except in highly endemic areas. Blastomycosis (also known as "North American blastomycosis", "Blastomycetic dermatitis", and "Gilchrist's disease") is a fungal infection of humans and other animals, notably dogs and occasionally cats, caused by the organism "Blastomyces dermatitidis".  Endemic to portions of North America, blastomycosis causes clinical symptoms similar to histoplasmosis.  The disease occurs in several endemic areas the most important of which is in eastern North America, particularly in the western and northern periphery of the Great Lakes Basin, extending eastward along the south shore of the St. Lawrence River Valley and southward in the territory spanned by the central Appalachian Mountains in the east, to the Mississippi River Valley in the west.  Sporadic cases have been reported in continental Africa, the Arabian Peninsula and the Indian subcontinent. Bikkia is a genus of flowering plants in the Rubiaceae family.  It is native to the Philippines, the Maluku region of eastern Indonesia, New Guinea and the western Pacific (Melanesia and Micronesia).  The genus was named by Caspar Reinwardt in 1825.  Seven of the New Caledonian species previously included in "Bikkia" were transferred to a separate genus, "Thiollierea", in 2011 based on molecular and morphological information.
