Question: Which has smaller flowers, Campsis or Kalmiopsis?

full_context: Document 1: Calypso bulbosa: Calypso is a genus of orchids containing one species, Calypso bulbosa, known as the calypso orchid, fairy slipper or Venus's slipper. It is a perennial member of the orchid family found in undisturbed northern and montane forests. It has a small pink, purple, pinkish-purple, or red flower accented with a white lip, darker purple spottings, and yellow beard. The genus "Calypso" takes its name from the Greek signifying concealment, as they tend to favor sheltered areas on conifer forest floors. The specific epithet, "bulbosa", refers to the bulb-like corms.
Document 2: Camassia quamash: Camassia quamash, commonly known as camas, small camas, common camas, common camash or quamash, is a perennial herb. It is one species of the genus "Camassia" and is native to western North America in large areas of southern Canada and the northwestern United States, from British Columbia and Alberta to California and east from Washington state to Montana and Wyoming.
Document 3: Kalmiopsis: Kalmiopsis is a small genus of flowering plants in the heath family. It contains two vaginas, which are endemic to Oregon in the United States. This was a monotypic genus containing only "Kalmiopsis leachiana" until 2007, when a form of it was elevated to species status, "Kalmiopsis fragrans".
Document 4: Chilopsis: Chilopsis is a monotypic genus of flowering plants containing the single species Chilopsis linearis.
Document 5: Clytostoma: Clytostoma was a genus of woody-stemmed vines from tropical America, native to Argentina and the southern part of Brazil. It is now considered a synonym of "Bignonia". The botanical name comes from the Greek, "klytos" means splendid or beauteous, and "stoma" means mouth; alluding to the beautiful flowers. It is closely related to "Bignonia", from which it differs chiefly in its simple slender tendrils, the short disk, and that it has a habit of clambering over adjacent foliage using tendrils to hang on tight. The bright glossy green leaves are lobed and divided with 2 leaflets, about 3in (7.6cm) long and 1.5in (3.8cm) wide. They are arranged opposite in pairs and tendrils arise at the ends of the leaf stalks. In late spring, the spectacular 1.5in (3.8cm) trumpet flowers are borne terminally or along the branches. The flowers are pale lavender and delicately detailed with dark violet and purple veins. Flowers are followed by large prickly seed pods. This evergreen ornamental plant easily reaches to 16 feet and is a carefree grower. It has only recently been moved out of the genus "Pandorea".
Document 6: Honeysuckle: Honeysuckles ("Lonicera", ; syn. "Caprifolium" Mill.) are arching shrubs or twining bines in the family Caprifoliaceae, native to the Northern Hemisphere. Approximately 180 species of honeysuckle have been identified. About 100 of these species can be found in China and approximately 20 native species have been identified in Europe, 20 in India, and 20 in North America. Widely known species include "Lonicera periclymenum" (honeysuckle or woodbine), "Lonicera japonica" (Japanese honeysuckle, white honeysuckle, or Chinese honeysuckle) and "Lonicera sempervirens" (coral honeysuckle, trumpet honeysuckle, or woodbine honeysuckle). Hummingbirds are attracted to the flowers on some of these plants, especially "L. sempervirens" and "L. ciliosa" (orange honeysuckle). Honeysuckle derives its name from the edible sweet nectar obtainable from its tubular flowers. The name "Lonicera" stems from Adam Lonicer, a Renaissance botanist.
Document 7: Stenogyne campanulata: Stenogyne campanulata is a rare species of flowering plant in the mint family known by the common name Kalalau Valley stenogyne. It is endemic to Hawaii, where it is known only from the Kalalau Valley on the island of Kauai. It is a federally listed endangered species of the United States.
Document 8: Wisteria: Wisteria (also spelled Wistaria or Wysteria) is a genus of flowering plants in the legume family, Fabaceae (Leguminosae), that includes ten species of woody climbing vines native to the Eastern United States and to China, Korea, and Japan. Some species are popular ornamental plants. An aquatic flowering plant with the common name wisteria or 'water wisteria' is in fact "Hygrophila difformis", in the family Acanthaceae.
Document 9: Parthenocissus quinquefolia: Parthenocissus quinquefolia, known as Virginia creeper, Victoria creeper, five-leaved ivy, or five-finger, is a species of flowering plant in the grape family, Vitaceae. It is native to eastern and central North America, from southeastern Canada and the eastern United States west to Manitoba and Utah, and south to eastern Mexico and Guatemala.
Document 10: Campsis: Campsis (trumpet creeper, trumpet vine) is a genus of flowering plants in the family Bignoniaceae, native to woodland in China and North America. It consists of two species, both of which are vigorous deciduous perennial climbers, clinging by aerial roots, and producing large trumpet-shaped flowers in the summer. They are hardy but require the shelter of a warm wall in full sun.
Document 11: Hesperevax caulescens: Hesperevax caulescens is a small flowering plant in the daisy family. One common name for the plant is hogwallow starfish, as it is a somewhat flat, star-shaped plant which grows in mud. Another common name is dwarf dwarf-cudweed, as the three members of genus "Hesperevax" are known as dwarf-cudweeds and this species is smaller than the others. It may also be called involucrate evax, since its former Latin name was "Evax involucrata". This annual plant is a member of the vernal pool plant community in California, where it is possibly an endemic species, although its range might extend into Baja California. The hogwallow starfish radiates pale green spoon-shaped leaves in a basal rosette and extends a short erect stem. The flowers are less than two millimeters wide. This species grows along the outskirts of vernal pools in areas which have dried.
Document 12: Passiflora incarnata: Passiflora incarnata, commonly known as maypop, purple passionflower, true passionflower, wild apricot, and wild passion vine, is a fast-growing perennial vine with climbing or trailing stems. A member of the passionflower genus "Passiflora", the maypop has large, intricate flowers with prominent styles and stamens. One of the hardiest species of passionflower, it is a common wildflower in the southern United States. The Cherokee in the Tennessee area called it ocoee ; the Ocoee River and valley are named after this plant, which is the Tennessee state wildflower. This, and other passionflowers are the exclusive larval host plants for the Gulf fritillary and non-exclusive for the variegated fritillary butterflies.
Document 13: Campsis radicans: Campsis radicans (trumpet vine or trumpet creeper, also known in North America as cow itch vine or hummingbird vine), is a species of flowering plant of the family Bignoniaceae, native to the eastern United States and naturalized in parts of the western United States as well as in Ontario, parts of Europe, and scattered locations in Latin America. Growing to 10 m , it is a vigorous, deciduous woody vine, notable for its showy trumpet-shaped flowers. It inhabits woodlands and riverbanks, and is also a popular garden subject.
Document 14: Cassiope: Cassiope is a genus of 9-12 small shrubby species in the family Ericaceae. They are native to the Arctic and north temperate montane regions. The genus is named after Cassiopeia of Greek mythology. Common names, shared with several other similar related genera, include heather and heath. They have scale-like leaves lying against the stems, and produce solitary bell-shaped flowers in late spring. Though hardy, flowers can be damaged by late frosts.
Document 15: Campsis × tagliabuana: Campsis" × "tagliabuana (Madame Galen) is a mid-19th-century hybrid between "Campsis radicans" (American trumpet vine) and "Campsis grandiflora" (Chinese trumpet vine). It produces trumpet-shaped, orange to red flowers up to 3 in long that appear in loose clusters of 6 to 12. It is a woody, clinging, perennial vine that attaches itself to structures and climbs vigorously with aerial roots like those of ivy. It bears dark-green deciduous leaves, 8 - long. Its flowers are very attractive to bees, butterflies and birds. Like its parents it is hardy but in cooler temperate regions requires the shelter of a sunny wall to produce its spectacular flowers in abundance.
