Question: Are both Tritonia and Degarmoara genuses comprised of hybrids?

full_context: Document 1: Grex (horticulture): The term grex (pl. greges or grexes; abbreviation gx), derived from the Latin noun "grex, gregis" meaning 'flock', has been coined to expand botanical nomenclature to describe hybrids of orchids, based solely on their parentage. Grex names are one of the three categories of plant names governed by the International Code of Nomenclature for Cultivated Plants; within a grex the "cultivar group" category can be used to refer to plants by their shared characteristics (rather than by their parentage), and individual orchid plants can be selected (and propagated) and named as cultivars.

Document 3: Angraecum: The genus Angraecum, abbreviated as Angcm in horticultural trade, common name Angrek (Indonesian and Malay) or Comet Orchid, contains about 220 species.
Document 4: Tritoniopsis: Tritoniopsis is a genus of flowering plants in the family Iridaceae, first described as a genus in 1926. The entire genus is endemic to Cape Province in South Africa. The genus name refers to the African genus "Tritonia" and is combined with the Greek word "opsis", meaning "look-alike".
Document 5: Brassocattleya: Brassocattleya or Brasso-cattleya, abbreviated Bc. in the horticultural trade, is an intergeneric orchid hybrid derived from the genera "Brassavola" and "Cattleya".
Document 6: Tigridia: Tigridia , the peacock flowers, tiger-flowers or shell flowers, is a genus of bulbous or cormous plants, belonging to the family Iridaceae. They have large showy flowers and one species, "Tigridia pavonia", is often cultivated for this. The approximately thirty five species in this family grow in the Western Hemisphere, from Mexico to Chile. The tigridia flower is short lived, each often blooming for only one day, but often several flowers will bloom from the same stalk. Usually they are dormant during the winter dry-season. Its roots are edible and were eaten by the Aztecs of Mexico who called it "cacomitl" and its flower "ocēlōxōchitl" "Jaguar flower". The genus name means "tiger-like" and alludes to the coloration and spotting of the flowers of the type species "Tigridia pavonia".
Document 7: Triteleia laxa: Triteleia laxa (previously "Brodiaea laxa") is a triplet lily known by several common names, including Ithuriel's spear, common triteleia and grassnut. It is native to California where it is a common wildflower, and it is occasionally found in southwestern Oregon. It bears a tall, naked stem topped with a spray of smaller stalks, each ending in a purple or blue flower. The flower is tubular, opening into a sharply six-pointed star. The plant grows from a corm which is edible and similar in taste and use as the potato. The most used common name for the species, Ithuriel's spear, is a reference to the angel Ithuriel from Milton's "Paradise Lost".
Document 8: Ascocenda: × Ascocenda, abbreviated as Ascda in the horticultural trade, is a man-made hybrid orchid genus resulting from a cross between "Ascocentrum" and "Vanda" (Asctm × V). It was first described in Orchid Rev. 57: 172 (1949).
Document 9: Phalaenopsis: Phalaenopsis , known as moth orchids, abbreviated Phal in the horticultural trade, is an orchid genus of approximately 60 species. "Phalaenopsis" is one of the most popular orchids in the trade, through the development of many artificial hybrids. It is native to southern China, Taiwan, the Indian Subcontinent, Southeast Asia (Thailand, Philippines, Malaysia, Indonesia, etc.), New Guinea, the Bismarck Archipelago, and Queensland.
Document 10: Fritillaria: Fritillaria is a genus of Eurasian, North African, and North American plants in the lily family.
Document 11: Zygotritonia: Zygotritonia is a genus of herbaceous, perennial and bulbous plants in the Iris family (Iridaceae). It contains four species distributed in Tropical Africa. The genus name is derived from the word zygomorphic (meaning bilabiate), and the apparent resemblance to some species in the genus "Tritonia".
Document 12: Tritonia (plant): Tritonia (flame freesia) is a genus of flowering plants in the iris family first described as a genus in 1802. They are naturally distributed across southern Africa, with a high concentration of species in Cape Province of western South Africa. The genus is closely related to the genus "Ixia".
Document 13: Kniphofia: Kniphofia , also called tritoma, red hot poker, torch lily, knofflers or poker plant, is a genus of flowering plants in the family Asphodelaceae, first described as a genus in 1794. It is native to Africa. Herbaceous species and hybrids have narrow, grass-like leaves 10 - long, while perennial species have broader, strap-shaped foliage up to 1.5 m long. All plants produce spikes of upright, brightly coloured flowers well above the foliage, in shades of red, orange and yellow, often bicoloured. The flowers produce copious nectar while blooming and are attractive to bees. In the New World they may attract sap-suckers such as hummingbirds and New World orioles.
Document 14: Degarmoara: × Degarmoara, abbreviated Dgmra. in the horticultural trade, is the nothogenus comprising intergeneric hybrids between the orchid genera "Brassia", "Miltonia" and "Odontoglossum" (Brs. x Milt. x Odm.).
Document 15: Fragaria × Comarum hybrids: There are several commercially important hybrids between "Fragaria" and "Comarum" species in existence, but they have not yet received formal botanical names as hybrids between those genera. Both "Fragaria" and "Comarum" have at different times been considered to be part of the genus "Potentilla", and these hybrids have been named Potentilla" x "rosea, or are sometimes referred to as "Fragaria" × "Potentilla" hybrids.
