Question: Which genus of plants contains a larger variety of species, Paulownia or Dendromecon?

full_context: Document 1: Hydrangea: Hydrangea ( ; common names hydrangea or hortensia) is a genus of 70–75 species of flowering plants native to southern and eastern Asia (China, Japan, Korea, the Himalayas, and Indonesia) and the Americas. By far the greatest species diversity is in eastern Asia, notably China, Japan, and Korea. Most are shrubs 1 to 3 meters tall, but some are small trees, and others lianas reaching up to 30 m by climbing up trees. They can be either deciduous or evergreen, though the widely cultivated temperate species are all deciduous.
Document 2: Dendromecon rigida: Dendromecon rigida, also called bush poppy or tree poppy, is a shrub or small tree of the Papaveraceae native to California and Baja California.
Document 3: Peucephyllum: Peucephyllum is a monotypic genus of flowering plants containing the single species Peucephyllum schottii. Its common names include pygmy cedar, Schott's pygmy cedar, desert fir, and desert pine. It is not a cedar, fir, or pine, but a member of the aster family, Asteraceae. It is a leafy evergreen shrub with glandular, resinous foliage. It flowers in yellow flower heads which have only disc florets. The fruits are woody, bristly seeds with a pappus. This plant is native to the deserts of Arizona, California, Nevada, and Utah in the United States and Baja California and Sonora in northern Mexico.
Document 4: 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 5: Ericameria laricifolia: Ericameria laricifolia is a North American species of flowering shrub in the daisy family known by the common name turpentine bush, or turpentine-brush. It is native to the southwestern United States (Arizona, New Mexico, western Texas, southwestern Utah, southern Nevada, southeastern California) and northern Mexico (Chihuahua).
Document 6: Stylophorum diphyllum: Stylophorum diphyllum (celandine-poppy, wood poppy, poppywort) is a herbaceous perennial native to moist woodland in eastern North America, valued for its yellow flowers. The common name is derived from greater celandine ("Chelidonium majus"), a closely related European plant with similarly shaped leaves and similarly coloured and shaped flowers.
Document 7: Delphinium purpusii: Delphinium purpusii is a rare species of larkspur known by the common names Kern County larkspur and rose-flowered larkspur. It is endemic to California where it is known only from Kern and Tulare Counties in the region where the Sierra Nevada meets the Mojave Desert. It grows on rocky cliffs and talus. This wildflower reaches between one half and one meter in height. The erect thin stem has deeply lobed leaves around the base and a small, narrow inflorescence of generally ten to 20 flowers at the top. The flowers of this species are bright pink, making it unusual among the mainly blue-flowered plants of this genus. The sepals curl either forward or back.
Document 8: Dendromecon: Dendromecon, the tree poppy, is a genus of one or two species of shrubs to small trees, native to California and northern Baja California.
Document 9: Fallopia: Fallopia is a genus of about 12–15 species of flowering plants in the buckwheat family, often included in a wider treatment of the related genus "Polygonum" in the past. The genus is native to temperate and subtropical regions of the Northern Hemisphere. The genus includes herbaceous perennial plants, herbaceous vines, and woody vines.
Document 10: Plagiobothrys canescens: Plagiobothrys canescens is a species of flowering plant in the borage family known by the common name valley popcornflower. It is endemic to California, where it is a common wildflower in valley, foothill, desert, coastline, and canyon habitat in the central and southern regions of the state.
Document 11: 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 12: Pueraria: Pueraria is a genus of 15–20 species of plants native to Asia. "Pueraria" flower is used in traditional Chinese medicine to reduce reactions to alcohol consumption, and is undergoing scientific study for that use.
Document 13: Rehmannia elata: Rehmannia elata (Chinese foxglove) is a species of flowering plant in the family Orobanchaceae, native to China. Growing to 150 cm tall by 50 cm broad, it is an herbaceous perennial with veined, hairy leaves and pink, tubular flowers with darker pink stripes in summer. The flowers bear a superficial resemblance to foxgloves, hence the common name "Chinese foxglove", which is also applied to the whole genus. However this species is not closely related to the true foxglove ("Digitalis").
Document 14: Chaenomeles: Chaenomeles is a genus of three species of deciduous spiny shrubs, usually 1–3 m tall, in the family Rosaceae. They are native to Japan, Korea, China, Bhutan, and Burma. (Burmese: ချဉ်စော်ကား ) These plants are related to the quince ("Cydonia oblonga") and the Chinese quince ("Pseudocydonia sinensis"), differing in the serrated leaves that lack fuzz, and in the flowers, borne in clusters, having deciduous sepals and styles that are connate at the base.
Document 15: 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.
