Banksia sessilis, commonly known as parrot bush, is a species of shrub or tree in the plant genus "Banksia" in the family Proteaceae.
 It had been known as Dryandra sessilis until 2007, when the genus "Dryandra" was sunk into "Banksia".
 The Noongar peoples know the plant as Budjan or Butyak.
 Widespread throughout southwest Western Australia, it is found on sandy soils over laterite or limestone, often as an understorey plant in open forest, woodland or shrubland.
 Encountered as a shrub or small tree up to 6 m in height, it has prickly dark green leaves and dome-shaped cream-yellow flowerheads.
 Flowering from winter through to late spring, it provides a key source of food—both the nectar and the insects it attracts—for honeyeaters in the cooler months, and species diversity is reduced in areas where there is little or no parrot bush occurring.
 Several species of honeyeater, some species of native bee, and the European honey bee seek out and consume the nectar, while the long-billed black cockatoo and Australian ringneck eat the seed.
 The life cycle of "Banksia sessilis" is adapted to regular bushfires.
 Killed by fire and regenerating by seed afterwards, each shrub generally produces many flowerheads and a massive amount of seed.
 It can recolonise disturbed areas, and may grow in thickets.
Hesperelaea is a plant genus with only one species, probably now extinct.
 Hesperelaea palmeri was found only on Guadalupe Island, a small island in the Pacific Ocean, part of the Mexican state of Baja California, about 400 km southwest of Ensenada.
 The last collection of the plant on the island was in 1875, so the species and the genus must now be presumed extinct.
 An intensive search for the plant in 2000 was unsuccessful.
Aldrovanda vesiculosa, commonly known as the waterwheel plant, is the sole extant species in the flowering plant genus "Aldrovanda" of the family Droseraceae.
 The plant captures small aquatic invertebrates using traps similar to those of the Venus flytrap.
 The traps are arranged in whorls around a central, free-floating stem, giving rise to the common name.
 This is one of the few plant species capable of rapid movement.
Falconeria is a monotypic plant genus in the family Euphorbiaceae, first described as a genus in 1839.
 The genus is sometimes included within the genus "Sapium".
 The sole species is Falconeria insignis.
 The plant is found from India, Nepal, Bangladesh, and Sri Lanka to Indochina, China (Hainan, Sichuan, Yunnan), Thailand and Peninsular Malaysia.
Phyllanthus is the largest genus in the flowering plant family Phyllanthaceae.
 Estimates of the number species in this genus vary widely, from 750 to 1200.
 "Phyllanthus" has a remarkable diversity of growth forms including annual and perennial herbs, shrubs, climbers, floating aquatics, and pachycaulous succulents.
 Some have flattened leaflike stems called cladodes.
 It has a wide variety of floral morphologies and chromosome numbers and has one of the widest range of pollen types of any seed plant genus.
Acanthopale is a plant genus in the Acanthaceae plant family.
 The genus name is based on the classic Greek words for thorn "ákantha" and stake "palum".
 Some species in the genus are cultivated as ornamental plants.
Beta is a genus in the flowering plant family Amaranthaceae.
 The best known member is the common beet, "Beta vulgaris", but several other species are recognised.
 Almost all have common names containing the word "beet".
 Wild "Beta" species can be found throughout the Atlantic coast of Europe, the Mediterranean coastline, the Near East, and parts of Asia including India.
The flowering plant genus Ipheion (starflower, spring starflower) belongs to Allioideae subfamily of the Amaryllidaceae family.
 The World Checklist of Selected Plant Families no longer recognize the genus, regarding it as a synonym of "Tristagma", although The Plant List accepts two species.
Cercospora beticola is a fungal plant pathogen which typically infects plants of the genus Beta, within the family of Chenopodiaceae.
 It is the cause of Cercospora leaf spot disease in sugar beets, spinach and swiss chard.
 Of these hosts, Cercospora leaf spot is the most economically impactful in sugar beets ("Beta vulgaris)".
 "Cercospora beticola" is a deuteromycete fungi that reproduces using conidia.
 There is no teleomorph stage.
 "C. beticola" is a necrotrophic fungi that uses phytotoxins specifically "Cercospora beticola" toxin (CBT) to kill infected plants.
 CBT causes the leaf spot symptom and prevents root formation.
 Yield losses from Cercospora leaf spot are around 20 percent.
Collinsia is a genus of about 20 species of annual flowering plants, consisting of the blue eyed Marys and the Chinese houses.
 It was traditionally placed in the snapdragon family Scrophulariaceae, but following recent research in molecular genetics, it has now been placed in a much enlarged family Plantaginaceae.

Question: are Beta and Collinsia both plant genus ?
Answer: yes
