Echinocereus triglochidiatus is a species of hedgehog cactus known by several common names, including kingcup cactus, claret cup cactus, red-flowered hedgehog cactus and Mojave mound cactus. This cactus is native to the southwestern United States and northern Mexico, where it is a resident of varied habitats from low desert to rocky slopes ...
This flower morphology is likely an adaptation to protect the developing buds from low temperatures. Upon maturity, the flowers are usually brightly colored and open during the day. Echinocereus floral color is variable because perianth color reflects pollinator specificity.
A cactus (pl.: cacti, cactuses, or less commonly, cactus) [3] is a member of the plant family Cactaceae (/ k æ k ˈ t eɪ s i. iː,-ˌ aɪ /), [a] a family of the order Caryophyllales comprising about 127 genera with some 1,750 known species. [4]
The Cactoideae are the largest subfamily of the cactus family, Cactaceae, and are widely distributed throughout the Americas. Cactaceae is the 5th most endangered plant or animal family evaluated globally by the International Union for Conservation of Nature. [1] Around 80% of cactus species belong to this subfamily. [2]
The name Cactus became so confused that the 1905 Vienna botanical congress rejected Cactus as a genus name, [4] and conserved Mammillaria. [ 1 ] Mammillaria is a large and diverse genus with many species often exhibiting variations due to the nature of terrain, weather, soil and other ecological factors.
One adaptation around this problem is the evolution of flattened cladodes that allow opuntioids to swell up with water, increasing in volume without an increase in surface area risking water loss. Opuntioids also lack fiber caps to their phloem bundles, which in other cacti protect against sucking insects and stiffen developing internodes .
The green cylindrical to elongated shoots are 16 to 45 centimeters long and have a diameter of 4 to 7.5 centimeters. The shoot surface is not completely covered by the spines. There are eight to 18 ribs that are not clearly tuberculated. The two to four straight, light-colored central spines have a darker tip and are 2.5 to 7.5 centimeters long.
The cactus fruits were always an important food for the Seri people, in Sonora; the dried cactus columns themselves could be used for construction purposes, as well as for firewood. [ 5 ] A symbiotic relationship with bacterial and fungal colonies, on its roots, allows P. pringlei to grow on bare rock, even where no soil is available at all ...
