Question: Are the Chirita plant and the Ferocactus cacti both found in Mexico?
Context: Chirita is an Old World genus of the flowering plant family Gesneriaceae, native to Indo-Malaysia, S. E. Asia, and southern China.  In 2011, the species in the genus were reassigned to several genera, with the type species ("C. urticifolia") assigned to the genus "Henckelia" (as "H. urticifolia" (Buch.-Ham.  ex D. Don.)  A. Dietr.) , so that "Chirita" became a synonym, no longer recognized. A cactus (plural: "cacti", "cactuses", or "cactus") is a member of the plant family Cactaceae, a family comprising about 127 genera with some 1750 known species of the order Caryophyllales.  The word "cactus" derives, through Latin, from the Ancient Greek κάκτος , "kaktos", a name originally used by Theophrastus for a spiny plant whose identity is not certain.  Cacti occur in a wide range of shapes and sizes.  Most cacti live in habitats subject to at least some drought.  Many live in extremely dry environments, even being found in the Atacama Desert, one of the driest places on earth.  Cacti show many adaptations to conserve water.  Almost all cacti are succulents, meaning they have thickened, fleshy parts adapted to store water.  Unlike many other succulents, the stem is the only part of most cacti where this vital process takes place.  Most species of cacti have lost true leaves, retaining only spines, which are highly modified leaves.  As well as defending against herbivores, spines help prevent water loss by reducing air flow close to the cactus and providing some shade.  In the absence of leaves, enlarged stems carry out photosynthesis.  Cacti are native to the Americas, ranging from Patagonia in the south to parts of western Canada in the north—except for "Rhipsalis baccifera", which also grows in Africa and Sri Lanka. The cochineal ( or ; Dactylopius coccus) is a scale insect in the suborder Sternorrhyncha, from which the natural dye carmine is derived.  A primarily sessile parasite native to tropical and subtropical South America as well as Mexico and Arizona, this insect lives on cacti in the genus "Opuntia", feeding on plant moisture and nutrients.  These insects are found on the pads of prickly pear cacti, then are brushed off and dried. The Hylocereeae are a tribe of cacti.  Found in the tropical forests of Central America, they are climbers or epiphytes, unlike most cacti.  In the classification of the International Cactaceae Systematics Group of the International Organization for Succulent Plant Study, the tribe has six genera. An epiphyte is an organism that grows on the surface of a plant and derives its moisture and nutrients from the air, rain, water (in marine environments) or from debris accumulating around it.  Epiphytes take part in nutrient cycles and add to both the diversity and biomass of the ecosystem in which they occur like any other organism.  They are an important source of food for many species.  Typically, the older parts of a plant will have more epiphytes growing on them.  Epiphytes differ from parasites in that epiphytes grow on other plants for physical support and do not necessarily negatively affect the host.  An epiphytic organism that is not a plant is sometimes called an epibiont.  Epiphytes are usually found in the temperate zone (e.g., many mosses, liverworts, lichens, and algae) or in the tropics (e.g., many ferns, cacti, orchids, and bromeliads).  Epiphyte species make good houseplants due to their minimal water and soil requirements.  Epiphytes provide a rich and diverse habitat for other organisms including animals, fungi, bacteria, and myxomycetes. Didymium wildpretii is a species of slime mold which feeds on the decaying remains of various species of cacti.  It was first described in 2007 and has been found across Mexico and the Canary Islands, but may be present where other cacti grow.  Its sporocarps are short (0.1–0.7 mm tall); their sporotheca is pale yellow with an orange stalk and their spores have a diameter of 7.5 μm.  When grown on agar, it completes its life cycle in 28–56 days.  It grows on basic media with a pH of 7.8–10.0, with optimum growth occurring at 8.5–9.4.  The species was named after Wolfredo Wildpret de la Torre, an expert in the flora of the Canary Islands. Ferocactus echidne is a barrel cactus in the genus "Ferocactus".  It is found in nature in Mexico.  This cactus is known commonly as Sonora barrel, Coville's barrel cactus, Emory's barrel cactus, and traveler's friend. Phytoliths (from Greek, "plant stone") are rigid, microscopic structures made of silica, found in some plant tissues and persisting after the decay of the plant.  These plants take up silica from the soil, whereupon it is deposited within different intracellular and extracellular structures of the plant.  Phytoliths come in varying shapes and sizes.  Although some use "phytolith" to refer to all mineral secretions by plants, it more commonly refers to siliceous plant remains.  In contrast, mineralized calcium secretions in cacti are composed of calcium oxalates. Ferocactus fordii (ford barrel cactus) is a species of flowering plant in the family Cactaceae, native to Baja California in Mexico.  It is spherical, growing to 50 cm in diameter, with whitish-grey radial spines and solitary flowers of a deep rose pink, 4 cm in diameter. Ferocactus is a genus of large barrel-shaped cacti, mostly with large spines and small flowers.  There are about 30 species included in the genus.  They are found in the southwestern United States and northwestern Mexico.
