Question: The genus Heuchera and the genus Glottiphyllum mark which type of living organism?

full_context: Document 1: Hellebore: Commonly known as hellebores , the Eurasian genus Helleborus consists of approximately 20 species of herbaceous or evergreen perennial flowering plants in the family Ranunculaceae, within which it gave its name to the tribe of Helleboreae. The scientific name "Helleborus" derives from the Greek name for "H. orientalis", ἑλλέβορος "helléboros", from "elein" "to injure" and βορά "borá" "food". Many species are poisonous. Despite names such as "winter rose", "Christmas rose" and "Lenten rose", hellebores are not closely related to the rose family (Rosaceae).
Document 2: Hepatica: Hepatica (hepatica, liverleaf, or liverwort) is a genus of herbaceous perennials in the buttercup family, native to central and northern Europe, Asia and eastern North America. Some botanists include "Hepatica" within a wider interpretation of "Anemone".
Document 3: Heuchera: Heuchera is a genus of evergreen, herbaceous perennial plants in the family Saxifragaceae, all native to North America. Common names include alumroot and coral bells.
Document 4: Brachyglottis: Brachyglottis is a genus of flowering plants in the aster family, Asteraceae. The genus was erected on November 29, 1775, by Johann Reinhold Forster and Georg Forster. The name was derived from the Greek "brachus" ("short")
Document 5: Conophytum: Conophytum is a genus of South African and Namibian succulent plants that belong to the Aizoaceae family. The name is derived from the Latin “conus” (cone) and Greek “phytum” (plant). The plants are also known as knopies (buttons), waterblasies (water blisters), sphaeroids, conos, cone plants, dumplings, or button plants.
Document 6: 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.
Document 7: Ericaceae: The Ericaceae are a family of flowering plants, commonly known as the heath or heather family, found most commonly in acid and infertile growing conditions. The family is large, with c. 4250 known species spread across 124 genera, making it the 14th most species-rich family of flowering plants. The many well-known and economically important members of the Ericaceae include the cranberry, blueberry, huckleberry, rhododendron (including azaleas), and various common heaths and heathers ("Erica", "Cassiope", "Daboecia", and "Calluna" for example).
Document 8: Titanopsis: Titanopsis is a genus of about 10 species of succulent plants of the family Aizoaceae, indigenous to the arid regions of South Africa and Namibia.
Document 9: Delosperma: Delosperma ('delos'=evident, 'sperma'=seed) is a genus of around 100 species of succulent plants, formerly included in "Mesembryanthemum" in the family Aizoaceae. The family is common in southern and eastern Africa.
Document 10: Glottiphyllum: Glottiphyllum is a genus of about 57 species of succulent subtropical plants of the family "Aizoaceae".
Document 11: Lithops: Lithops is a genus of succulent plants in the ice plant family, Aizoaceae. Members of the genus are native to southern Africa. The name is derived from the Ancient Greek words λίθος ("lithos"), meaning "stone," and ὄψ ("ops"), meaning "face," referring to the stone-like appearance of the plants. They avoid being eaten by blending in with surrounding rocks and are often known as pebble plants or living stones. The formation of the name from the Greek "-ops" means that even a single plant is called a Lithops.
Document 12: × Heucherella: × "Heucherella" is an evergreen perennial flowering plant in the family Saxifragaceae. A hybrid of garden origin, it is the result of a cross between two distinct genera, "Heuchera" and "Tiarella", and shows similarities to both parents. This type of intergeneric hybrid is quite rare, and is indicated by a multiplication symbol before the name. The name "Heucherella" is an example of a portmanteau word, a combination of the two parents' names.
Document 13: Aeonium glutinosum: Aeonium glutinosum is a species of flowering plant in the family "Crassulaceae". It has fairly thick leaves and its appearance varies depending on its growing conditions. One characteristic is the very sticky stem of the inflorescence. The main flower is shown but small stalks with flowers continue to appear for several months
Document 14: Alum root: Alum root or Alumroot is a common name for some species of two different genera of flowering plants:
Document 15: Erica: Erica is a genus of roughly 860 species of flowering plants in the family Ericaceae. The English common names "heath" and "heather" are shared by some closely related genera of similar appearance. The genus "Calluna" was formerly included in "Erica" – it differs in having even smaller scale-leaves (less than 2–3 mm long), and the flower corolla consisting of separate petals. "Erica" is sometimes referred to as "winter (or spring) heather" to distinguish it from "Calluna" "summer (or autumn) heather".
