Catopsis is a genus in the botanical family Bromeliaceae, subfamily Tillandsioideae.
 The genus name is from the Greek “kata” (hanging down) and “opsis” (appearance).
 "Catopsis" is a genus of plants widespread across much of Latin America from Mexico to Brazil, plus Florida and the West Indies.
 One of the species, "Catopsis berteroniana", is thought to be carnivorous.
Cucurbita texana, also known as Cucurbita pepo" subsp.
 "texana and Texas gourd, is a mesophyte plant species of the genus "Cucurbita".
 It is native to Texas, primarily the southeastern region.
 It is found only in the wild.
 It is possibly a progenitor and close relative of the domesticated species "Cucurbita pepo", though it and wild "C. pepo" are native to different areas. "
Cucurbita fraterna" is also closely related.
 It was first collected 1835 by J. L. Berlandier in southern Texas.
 It was formally described as "Tristemon texanus" by George Heinrich Adolf Scheele in 1848 and transferred to the genus "Cucurbita" by Asa Gray in 1850.
Cucurbita palmata is a species of flowering plant in the squash family known by the common names coyote melon and coyote gourd.
 It is similar to "Cucurbita californica", "Cucurbita cordata", "Cucurbita cylindrata", and "Cucurbita digitata" and all these species hybridize readily.
 It was first identified by Sereno Watson in 1876.
 These species form the only restricted xerophyte species group in the genus "Cucurbita".
 Each member of this species group is native to the Southwestern United States and Northwestern Mexico where they are relatively uncommon.
 Each group member is found in hot, arid regions with low rainfall.
 They prefer soil that is loose, gravelly, and well-drained.
 "C. palmata" is native to northeastern Baja California, southeastern California, and southwestern Arizona to a point near the Colorado River.
 The juvenile leaves of "C. cylindrata", "C. cordata", "C. digitata", and "C. palmata" show a high degree of similarity, but their mature leaves are visibly different, as are their root structures.
 "C. palmata" and "C. digitata" are sympatric, with "C. palmata" separating the ranges of "C. digitata" at the juncture of Baja California, California, and Arizona.
 "C. palmata" fruits are diffuse green mottle that turns yellow at maturity, striped, and round.
Cucurbita cordata is a species of flowering plant in the squash family.
 It is similar to "Cucurbita californica", "Cucurbita cylindrata", "Cucurbita digitata", and "Cucurbita palmata" and all these species hybridize readily.
 These species form the only restricted xerophyte species group in the genus "Cucurbita".
 Each member of this species group is native to the Southwestern United States and Northwestern Mexico where they are relatively uncommon.
 Each group member is found in hot, arid regions with low rainfall.
 They prefer soil that is loose, gravelly, and well-drained.
 "C. cordata" is found only in the vicinity of Bahía de los Ángeles, Baja California.
 Botanists Bemis and Whitaker suggest that "C. cordata" and "C. cylindrata" may be a case of sympatric speciation.
 The juvenile leaves of "C. cylindrata", "C. cordata", "C. digitata", and "C. palmata" show a high degree of similarity, but their mature leaves are visibly different, as are their root structures.
 "C. cordata" fruits are gray green, striped, and round.
Cucurbita digitata is a species of flowering plant in the squash family known by the common names fingerleaf gourd and bitter squash.
 It is similar to "Cucurbita californica", "Cucurbita cordata", "Cucurbita cylindrata", and "Cucurbita palmata" and all these species hybridize readily.
 These species form the only restricted xerophyte species group in the genus "Cucurbita".
 Each member of this species group is native to the Southwestern United States and Northwestern Mexico where they are relatively uncommon.
 Each group member is found in hot, arid regions with low rainfall.
 They prefer soil that is loose, gravelly, and well-drained.
 "C. digitata" is native to northern Baja California at higher elevations, northern Sonora, Mexico, southern Arizona, and southwestern New Mexico.
 The juvenile leaves of "C. cylindrata", "C. cordata", "C. digitata", and "C. palmata" show a high degree of similarity, but their mature leaves are visibly different, as are their root structures.
 "C. palmata" and "C. digitata" are sympatric, with "C. palmata" separating the ranges of "C. digitata" at the juncture of Baja California, California, and Arizona.
 "C. digitata" fruits are clear green mottle that turns yellow at maturity, striped, and round.
Cucurbita cylindrata is a species of flowering plant in the squash family.
 It is similar to "Cucurbita californica", "Cucurbita cordata", "Cucurbita digitata", and "Cucurbita palmata" and all these species hybridize readily.
 These species form the only restricted xerophyte species group in the genus "Cucurbita".
 Each member of this species group is native to the Southwestern United States and Northwestern Mexico where they are relatively uncommon.
 Each group member is found in hot, arid regions with low rainfall.
 They prefer soil that is loose, gravelly, and well-drained.
 "C. cylindrata" is found only in the middle portion of Baja California, mostly in Baja California Sur.
 Botanists Bemis and Whitaker suggest that "C. cordata" and "C. cylindrata" may be a case of sympatric speciation.
 The juvenile leaves of "C. cylindrata", "C. cordata", "C. digitata", and "C. palmata" show a high degree of similarity, but their mature leaves are visibly different, as are their root structures.
 "C. cylindrata" fruits are dark green, striped, and round.
Cucurbita maxima, one of at least four species of cultivated squash, is one of the most diverse domesticated species.
 This species originated in South America from the wild "Cucurbita andreana" over 4000 years ago.
 The two species hybridize quite readily but have noticeably different calcium levels.
Cucurbita (Latin for gourd) is a genus of herbaceous vines in the gourd family, Cucurbitaceae, also known as cucurbits, native to the Andes and Mesoamerica.
 Five species are grown worldwide for their edible fruit, variously known as squash, pumpkin, or gourd depending on species, variety, and local parlance, and for their seeds.
 First cultivated in the Americas before being brought to Europe by returning explorers after their discovery of the New World, plants in the genus "Cucurbita" are important sources of human food and oil.
 Other kinds of gourd, also called bottle-gourds, are native to Africa and belong to the genus "Lagenaria", which is in the same family and subfamily as "Cucurbita" but in a different tribe.
 These other gourds are used as utensils or vessels, and their young fruits are eaten much like those of Cucurbita species.
