Xerophytic plants exhibit a diversity of specialized adaptations to survive in such water-limiting conditions. They may use water from their own storage, allocate water specifically to sites of new tissue growth, or lose less water to the atmosphere and so channel a greater proportion of water from the soil to photosynthesis and growth.
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.
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 ...
The flower buds are blunt shaped. [5] The flowers are fragrant highly variable in color, the colored inner tepals (casually called petals) coming in white, pink, magenta, yellow, or yellow-green. [7] [3] The size of the flowers of Pediocactus simpsonii ranges from 1.2–3 centimeters across and 1–2.5 centimeters in depth. [3]
Echinocereus stramineus is a species of cactus, with stramineus meaning made of straw. There are various common names such as strawberry cactus, porcupine hedgehog cactus, straw-color hedgehog, and pitaya. The straw-colored spines distinguishes this particular plant from other Echinocereus. The aged spines may turn white in color and are very ...
Silver cholla is a large, shrub to tree-like cactus which may exceed 0.5 to 2 m (1.6 to 6.6 ft) in height. Its stems and branches are made up of cylindrical green tubercles (segments) up to 1.5 cm wide and just under 1.0 cm tall. The elliptical white or yellow areoles turn gray and bear conspicuous yellow glochids that are 3 to 4 millimeters long.
Flowers grow 8.6–12.4 cm (3.4–4.9 in) long, and are open for less than 24 hours. Since they form only at the top of the plant and the tips of branches, saguaros growing numerous branches is reproductively advantageous. Flowers open sequentially, with plants averaging four flowers open per day over a bloom period lasting a month. [7]
