Question: Aethionema and Physoplexis are both native flowering plants from which continent?

Context paragraphs:
Dierama: Dierama, is a genus of flowering plants in the iris family, Iridaceae.  Common names include hairbells, Angel's Fishing Rod, fairybells, and wandflowers in English and grasklokkies in Afrikaans.  They are native to Africa, with most occurring in the southern regions of the continent.  The center of diversity is the Province of KwaZulu-Natal in eastern South Africa.

Richardia: Richardia (Mexican-clover) is a small genus of about 15 species of flowering plants in the family Rubiaceae, native to tropical to warm temperate regions of the Americas, with one species also native to Fiji in the Pacific Ocean.  They are mostly annual plants, a few species being herbaceous perennial plants.

Physoplexis: Physoplexis comosa, the tufted horned rampion is a species of flowering plant in the family Campanulaceae, native to alpine Europe.  It is the only species in its genus, and was formerly included in "Phyteuma".

Scolopterus penicillatus: Scolopterus penicillatus, also known as the black spined weevil, is an endemic beetle of New Zealand.  The beetle is present throughout New Zealand and can be discovered by beating native flowering plants in the summer months.  In appearance it is a shining black colour with a purplish tinge and looks very similar to its close relative "Scolopterus tetracanthus".  "S. penicillatus" can be distinguished from "S. tetracanthus" as the spines on the shoulders of the former are much less pointed.  Adult black spined weevils have been collected from "Hedychium gardnerianum" and caught in the flowers of "Helichrysum lanceolatum".  The larvae of "S. penicillatus" are known to develop in the recently dead bark of the various species of "Pseudopanax".

Eugenia: Eugenia is a genus of flowering plants in the myrtle family Myrtaceae.  It has a worldwide, although highly uneven, distribution in tropical and subtropical regions.  The bulk of the approximately 1,000 species occur in the New World tropics, especially in the northern Andes, the Caribbean, and the Atlantic Forest (coastal forests) of eastern Brazil.  Other centers of diversity include New Caledonia and Madagascar.  Many species new to science have been and are in the process of being described from these regions.  For example, 37 new species of "Eugenia" have been described from Mesoamerica in the past few years.  At least 20 new species are currently in the process of being described from New Caledonia, and approximately the same number of species new to science may occur in Madagascar.  Despite the enormous ecological importance of the myrtle family in Australia (e.g. "Eucalyptus", "Corymbia", "Angophora", "Melaleuca", "Callistemon", "Rhodamnia", "Gossia"), only one species of "Eugenia", "E. reinwardtiana", occurs on that continent.  The genus also is represented in Africa south of the Sahara, but it is relatively species-poor on that continent.  In the past some botanists included the morphologically similar Old World genus "Syzygium" in "Eugenia", but research by Rudolf Schmid in the early 1970s convinced most botanists that the genera are easily separable.  Research by van Wyk and colleagues in South Africa suggests the genus may comprise at least two major lineages, recognizable by anatomical and other features.

Lilium: Lilium (members of which are true lilies) is a genus of herbaceous flowering plants growing from bulbs, all with large prominent flowers.  Lilies are a group of flowering plants which are important in culture and literature in much of the world.  Most species are native to the temperate northern hemisphere, though their range extends into the northern subtropics.  Many other plants have "lily" in their common name but are not related to true lilies.

Colobanthus quitensis: Colobanthus quitensis (Antarctic pearlwort) is one of two native flowering plants found in the Antarctic region.  It occurs on the continental edge, as well as the South Orkney Islands and the South Shetland Islands.  It has yellow flowers and grows about 5 cm (two inches) tall, with a cushion-like growth habit that gives it a moss-like appearance.

Petroselinum: Petroselinum (parsley) is a genus of two species of flowering plants in the family Apiaceae, native to western and southern Europe and northern Africa.  They are bright green hairless biennial herbaceous plants, rarely annual plants.  In the first year, they form a rosette of pinnate to tripinnate leaves and a tap root used as a food store over the winter.  In the second year they grow a flowering stem up to 1 m tall with sparser leaves and umbels of white or pinkish to yellowish-green flowers.

Aethionema: Aethionema syn.  "Eunomia" is a genus of flowering plants, within the family Brassicaceae, subfamily Brassicoideae.  The genus is collectively known as the stonecresses.  They originate from sunny limestone mountainsides in Europe and West Asia, especially Turkey.

Eupomatia laurina: Eupomatia laurina, commonly named bolwarra or sometimes native guava or copper laurel is a species of shrubs to small trees, of the Australian continent ancient plant family Eupomatiaceae.  They often grow between 3 and tall, larger specimens may attain 15 m and a trunk diameter of 30 cm .  They grow naturally in eastern Australia and New Guinea.  In Australia, they grow as far south as Nowa Nowa in the humid forests of the warm temperate east of the state of Victoria through eastern New South Wales and Queensland north to tropical Cape York Peninsula.  They are one of the ancient lineages of flowering plants, usually growing as part of an understorey in rainforests or humid Eucalypt forests.
