Question: Are Decaisnea and Weldenia native to the same area?

full_context: Document 1: Deinanthe: Deinanthe is a genus consisting of a few species of rare herbaceous-habit rhizomatous plants found in the mountain woodlands of East Asia, ranging from China to Japan. They are handsome clump-forming perennials good for shade, woodland and rock gardens. These attractive deciduous plants have relatively large "fishtail" leaves (cleft at the apex). Deinanthes grow at a slow rate to be bushy and shrub-like, 2ft tall and wide. The leaves attain 3 to 4 inches in length,being deep green, roughly textured, deep veined, cordate at their bases and with serrate margins. The shoots emerge from stout, knobby rhizomes. Leaves are easily damaged in direct sun exposure. Flowering occurs in late summer to early fall. The delicate, waxy, nodding cup-shaped flowers in rich to pale purple-blue, rose or white, are borne in loose terminal clusters. Resembling gargantuan fertile hydrangea flowers, with numerous yellowish to pale blue anthers, they are occasionally accompanied by sterile flowers, as in the lacecap hydrangeas. Roots and leaves are edible.
Document 2: Maurandya: Maurandya is a genus of flowering plants in the plantain family, Plantaginaceae, native to Mexico and the south west United States (from California to central Texas). They sprawl or climb by means of twining leaf stalks. One of the four species, "Maurandya barclayana", is widely cultivated as an ornamental plant.
Document 3: Dactylorhiza hatagirea: Dactylorhiza hatagirea is a species of orchid generally found growing in the Himalayas, from Pakistan to SE Tibet, at altitudes of 2800 - . It is locally called 'Salam Panja' or 'Hatta Haddi'. It is called 'Panchaule' (पाँचऔंले) in Nepali and Himalayan regions. The name 'Panchaule' (meaning 5 fingered hand) arises from its root resembling fingers of hand with around 3-5 fingers. It is an erect perennial herb with long flowering stems. The plant is well known for its medicinal value. The root has sweet taste. It is strictly prohibited for collection and sale, but can be found easily around Nepal. It costs around NRs. 10,000-15,000 per kilo as of late 2015.
Document 4: Decaisnea: Decaisnea, known commonly as dead man's fingers, blue bean plant or blue sausage fruit, is a genus of flowering plant in the family Lardizabalaceae. It is native to eastern Asia, from China west to Nepal and south to Myanmar.
Document 5: Commelinaceae: Commelinaceae is a family of flowering plants. In less formal contexts, the group is referred to as the dayflower family or spiderwort family. It is one of five families in the order Commelinales and by far the largest of these with about 731 known species in 41 genera. Well known genera include "Commelina" (dayflowers) and "Tradescantia" (spiderworts). The family is diverse in both the Old World tropics and the New World tropics, with some genera present in both. The variation in morphology, especially that of the flower and inflorescence, is considered to be exceptionally high amongst the angiosperms.
Document 6: Wulfenia: Wulfenia is a plant genus in the family Plantaginaceae. Named after Franz Xaver von Wulfen (1728–1805), it was first described in 1781 by Nikolaus Joseph von Jacquin.
Document 7: Weldenia: Weldenia is a monotypic genus of flowering plant in the Commelinaceae family, first described in 1829. It has one single species: Weldenia candida, which grows originally in Mexico and Guatemala.
Document 8: Wigandia: Wigandia is a genus of flowering plants within the waterleaf subfamily, Hydrophylloideae. They are found mainly in Central America and South America, though one or two species are found as far north as the United States. Some are grown as ornamental plants and will flourish in most Mediterranean or temperate regions. The genus is named for Johann Wigand (ca. 1523-1587), German Lutheran cleric and theologian, and Bishop of Pomesania.
Document 9: Centradenia: Centradenia is a genus of 4-5 species of tropical evergreen perennials or subshrubs, native to Central America and Mexico.
Document 10: Paulownia: Paulownia is a genus of six to 17 species (depending on taxonomic authority) of flowering plants in the family Paulowniaceae, related to and sometimes included in the Scrophulariaceae. They are present in much of China, south to northern Laos and Vietnam and are long cultivated elsewhere in eastern Asia, notably in Japan and Korea. They are deciduous trees 12 – tall, with large, heart-shaped leaves 15–40 cm across, arranged in opposite pairs on the stem. The flowers are produced in early spring on panicles 10–30 cm long, with a tubular purple corolla resembling a foxglove flower. The fruit is a dry capsule, containing thousands of minute seeds.
Document 11: Maurandya wislizeni: Maurandya wislizeni is a scrambling or climbing herbaceous annual native to Mexico and the south western United States (Texas, Arizona and New Mexico) where it grows in sand dunes. It has tubular flowers in shades of blue to violet and white and more-or-less triangular untoothed leaves. It has been placed in a separate genus as Epixiphium wislizeni.
Document 12: Deutzia: Deutzia ( or ) is a genus of about 60 species of flowering plants in the family Hydrangeaceae, native to eastern and central Asia (from the Himalayas east to Japan and the Philippines), and Central America and also Europe. By far the highest species diversity is in China, where 50 species occur.
Document 13: Dichroa: Dichroa is a genus of 12 species of flowering plants in the family Hydrangeaceae, native to eastern and southeastern Asia. They are deciduous shrubs growing to 1-3 m tall, with their leaves arranged in opposite pairs. The flowers are produced in a broad inflorescence similar to that of the related genus "Hydrangea". The fruit is a glossy metallic purple-blue berry.
Document 14: Wislizenia: Wislizenia is a genus of flowering plants containing three recognized species native to the southwestern United States and northern Mexico. Common names include spectacle fruit and jackass clover. Like genus "Cleome" and several relatives, "Wislizenia" has traditionally been included in the caper family, Capparaceae, but has more recently been moved to the new family Cleomaceae.
Document 15: Caulophyllum: Caulophyllum is a small genus of perennial herbs in the family Berberidaceae. It is native to eastern Asia and eastern North America. These plants are distinctive spring wildflowers, which grow in moist, rich woodland, it is known for its large triple-compound leaf, and large blue, berry-like fruits. Unlike many spring wildflowers, it is not an ephemeral plant and persists throughout much of the summer. Common names for plants in this genus include Blue Cohosh, Squaw Root, and Papoose Root. As hinted at by its common names, this plant is well known as an alternative medicine for inducing childbirth and menstrual flow; it is also considered a poisonous plant.
