Question: Callirhoe and Dischidia are both genus of plants and one is known as poppy mallows, which?
Context: Malva pusilla, also known as Malva rotundifolia (the latter of which is now officially rejected by botanists), the low mallow, small mallow, or the round-leaved mallow, is an annual and biennial herb species of the Mallow genus "Malva" in the family of Malvaceae.  Malva is a genus that consists of about 30 species of plants.  This genus consists of plants named mallows.  Mallows grow in many regions, including temperate, subtropical, and tropical areas. Callirhoe is a genus of flowering plants in the mallow family, Malvaceae.  Its nine species are commonly known as poppy mallows and all are native to the prairies and grasslands of North America.  Of the nine, some are annuals while others are perennial plants. Dischidia major, the Malayan urn vine, is an unusual plant.  "Dischidia" is a genus of some 80 species of trailing, twining or scandent, succulent epiphytes found throughout the tropics of Asia (New Guinea, Moluccas, Philippines, India, tropical Australia, Hong Kong, Taiwan) through to the western Pacific.  They carry modified leaves, offering accommodation to ants, including those of the family Dolichoderinae, and in return gain some sustenance from increased carbon dioxide and nitrogen levels, and a degree of protection from noxious animals and plants.  This mutualism trait, known as myrmecophily, is widespread across the plant world and clearly carries considerable benefits for both ants and plant. Dischidia is a genus of plants in the Milkweed family, Apocynaceae.  They are epiphytes native to tropical areas of China, India and most areas of Indo-China.  "Dischidia" are closely aligned with the sister genus "Hoya".  Unlike "Hoya", the genus "Dischidia" is poorly known and has not been studied as closely. A poppy is a flowering plant in the subfamily Papaveroideae of the family Papaveraceae.  Poppies are herbaceous plants, often grown for their colorful flowers.  One species of poppy, "Papaver somniferum", is the source of the crude drug opium which contains powerful medicinal alkaloids such as morphine and has been used since ancient times as an analgesic and narcotic medicinal and recreational drug.  It also produces edible seeds.  Following the trench warfare which took place in the poppy fields of Flanders during World War I, poppies have become a symbol of remembrance of soldiers who have died during wartime. Meconic acid, also known as acidum meconicum and poppy acid, is a chemical substance found in certain plants of the Papaveraceae family (poppy) such as "Papaver somniferum" (opium poppy) and "Papaver bracteatum".  Meconic acid constitutes about 5% of opium and can be used as an analytical marker for the presence of opium.  Meconic acid has erroneously been described as a mild narcotic, but it has little or no physiological activity, and is not used medicinally.  Meconic acid forms salts with alkaloids and metals.  These salts as well as meconic acid esters are called meconates.  Meconic acid was first isolated by Friedrich Sertürner in 1805. Diadasia is a genus of bees in family Apidae.  Species of "Diadasia" are oligolectic, specialized on a relatively small number of plant species.  Their host plants include asters, bindweeds, cacti, mallows, and willowherbs, although mallows are the most common and likely ancestral host plant for the whole genus.  Its tribe is Emphorini. Hunnemannia is a monotypic genus of flowering plants in the poppy family Papaveraceae, containing the single species Hunnemannia fumariifolia (tulip poppy or Mexican tulip poppy) native to the highlands of Mexico.  It is typically found at elevations of 1500 - in the Chihuahuan Desert and south into central Mexico, where it favors rocky habitats, occurring along roadsides as well. Sphaeralcea is a genus of flowering plants in the mallow family (Malvaceae).  There are about 40-60 species, including annuals, perennials, and shrubs. Most originate in the drier regions of North America, with some known from South America.  They are commonly known as globemallows, globe mallows, or falsemallows.  The name of the genus is derived from the Greek words σφαῖρα ("sphaira"), meaning "sphere," and αλκεα ("alkea"), meaning "mallow." Callirhoe scabriuscula is a rare species of flowering plant in the mallow family known by the common name Texas poppy mallow.  It is endemic to Texas, where it is known from about ten populations in the deep sands alongside the Colorado River.  Much of its habitat has been lost, which is the reason it was federally listed as an endangered species in 1981.
