| Echeveria runyonii | |
Echeveria runyonii is a species of flowering plant in the family Crassulaceae, [1] that is native to the state of Tamaulipas in Mexico. [2] Several cultivars have been described and cultivated.
Joseph Nelson Rose described Echeveria runyonii in 1935, [1] named in honour of Texas amateur botanist Robert Runyon. [3] Runyon had collected the type specimen from a Matamoros, Tamaulipas garden [4] in 1922. [5] [6] Wild populations were unknown until 1990, when one was discovered by the staff of Yucca Do Nursery. [7]
The cytology of Echeveria species is helpful in identification, as many species can be very variable in appearance; E. runyonii has 14 chromosomes. [1]
Echeveria is named for Atanasio Echeverría y Godoy, a botanical illustrator who contributed to Flora Mexicana. [8]
Echeveria runyonii forms a rosette 8–10 cm (3.1–3.9 in) in diameter. Leaves are spatulate-cuneate to oblong-spatulate, truncate to acuminate, and mucronate. They are a glaucous pinkish-white in color and measure 6–8 by 2.5–4 cm (2.4–3.1 by 1.0–1.6 in). The single stem reaches 10 cm (3.9 in) in length or more and a diameter of roughly 1 cm (0.39 in). Inflorescences are 15–20 cm (5.9–7.9 in) tall and have 2 – 3 cincinni, conspicuous bracts, and pedicels approximately 4 mm long. The red flowers have ascending-spreading sepals to 11 mm and pentagonal corollas measuring 19 – 20 × 10 mm. [1]
Echeveria desmetiana has similar-coloured glaucous leaves, but its leaves are wedge-shaped with mucronulate (pointed) tips. [9]
Several named cultivars exist, including 'Texas Rose', 'Dr. Butterfield', 'Lucita', 'Tom Allen', and 'Topsy Turvy'. The last is a mutant form originated in California, with leaves positioned upside-down. [10]
Echeveria is a large genus of flowering plants in the family Crassulaceae, native to semi-desert areas of Central America, Mexico and northwestern South America.
Dudleya, commonly known as liveforevers is a genus of rosette-forming succulent plants in the stonecrop family, Crassulaceae, consisting of about 68 taxa in southwestern North America and Guadalupe Island. The species come in many forms, with some large and evergreen, others geophytic and deciduous. Yet, despite their dramatic variations in appearance, most species readily hybridize. The flowers of Dudleya have parts numbered in fives, with the petals arranged in tubular, star-shaped, and bell-shaped forms and, when fruiting, are filled with tiny, ovoid-crescent-shaped seeds.
Dudleya candelabrum is a species of succulent plant known by the common names candleholder liveforever or candleholder dudleya. Endemic to California, this species grows wild only on the northern Channel Islands, where it is found in open rocky places and north-facing slopes. It is characterized by thin, spade-shaped green leaves and an inflorescence covered in long, reflexed bracts, with pale yellow flowers. It has been threatened by poachers shipping plants to South Korea.
Dudleya farinosa is a species of succulent plant in the family Crassulaceae known by several common names, including bluff lettuce, powdery liveforever, and powdery dudleya. A coastal plant of northern California and southern Oregon, it is typically found on oceanic bluffs just directly above the reach of the waves. Its appearance is characterized by lotus-like rosettes of beveled leaves, and in summer the plant erects a tall pink to red stem densely covered in foliage, topped with branches adorned with pale yellow flowers. The green or white rosettes of this plant can be seen covering stretches of rocky coast and nearby islets.
Dudleya traskiae is a rare succulent plant known by the common name Santa Barbara Island liveforever. This Dudleya is endemic to Santa Barbara Island, one of the Channel Islands of California, where it grows on rocky bluffs. The plant has a basal rosette of flat, spade-shaped fleshy leaves up to 15 centimeters long, which are pale green to yellowish. It erects tall stems bearing dense, rounded inflorescences of many bright yellow flowers.
Dudleya greenei is a perennial species of succulent plant known by the common names Greene's liveforever, or Greene's dudleya. It is endemic to the Channel Islands of California, where it grows along the cliffs of four of the eight islands. It is a highly variable plant, presenting with multiple forms and varying levels of ploidy. Taxonomically, this species is an insular segregate of Dudleya caespitosa, and was placed as a stopgap taxon by Reid Moran in his 1951 thesis on the genus. It is characterized by white or green leaf rosettes, loomed over by inflorescences bearing pale yellow to white flowers. It is a member of the subgenus Dudleya, as it cannot be propagated from leaf cuttings, does not grow from a corm, and has tight petals.
Echeveria elegans, the Mexican snow ball, God's Throne, Mexican gem or white Mexican rose is a species of flowering plant in the family Crassulaceae, native to semi-desert habitats in Mexico.
Crassula picturata is a species of plant in the family Crassulaceae, native to Cape Province in South Africa. It is a stemless plant with triangular, dark green leaves measuring approximately 10–12 cm long by 1 cm wide.
Echeveria agavoides, or lipstick echeveria, is a species of flowering plant in the family Crassulaceae, native to rocky areas of Mexico, notably the states of San Luis Potosí, Hidalgo, Guanajuato and Durango.
Echeveria desmetiana, incorrectly known as Echeveria peacockii, is a succulent plant in the family Crassulaceae. L. de Smet was the first grower of this plant.
Echeveria strictiflora, the desert savior, is a species of flowering plant in the family Crassulaceae, native to southwestern Texas and to the Chihuahuan Desert of northeast Mexico. Its range consists of several scattered populations, rather than a contiguous range.
Echeveria gibbiflora is a species of flowering plant in the family Crassulaceae. It was described by Swiss botanist Augustin Pyramus de Candolle in 1828. It occurs in Mexico and Guatemala.
Afrovivella is a monotypic genus of the succulent plant family Crassulaceae. The sole species is Afrovivella semiensis.
Echeveria amoena is a species of succulent plant in the family Crassulaceae, endemic to semi-arid areas of the Mexican states of Puebla, Tlaxcala, and Veracruz.
Dudleya gatesii, known by the common name as Gates'liveforever, is a species of perennial succulent plant in the family Crassulaceae. It is native to the central desert of the Baja California peninsula, found growing along dry and rocky outcroppings. It is characterized by red inflorescences topped with white flowers, bracts that are often reflexed downwards, and a rosette of dark-green leaves turning reddish.
Dudleya saxosa subsp. collomiae, known by the common name Gila County liveforever, is a subspecies of perennial succulent plant within the genus Dudleya native to central Arizona. It is characterized by showy bright-yellow flowers on an upright inflorescence colored pink, red or orange. The leaves are green or covered in a white, powdery wax. This species is found growing in rocky slopes, canyons, and crevices, and often on Sonoran Desert sky islands.
Reidmorania occidentalis is a succulent plant in the stonecrop family (Crassulaceae) native to the state of Sinaloa in Mexico. It is within the monotypic genus Reidmorania, which is named after botanist Reid Moran, who was notable for his research in the Crassulaceae family.
Dudleya cymosasubsp. pumila, most commonly known as the low canyon dudleya, chalky canyon dudleya or California live-forever, is a species of perennial succulent plant. It has diamond to spoon shaped leaves, sometimes coated with a fine white powder, and in May through July, bright red, orange or yellow flowers adorn the short inflorescence. A leaf succulent primarily found growing in rocky cliffs and slopes, it is endemic to California, and grows in the Transverse Ranges and South Coast Ranges, with some outlying populations. A variable plant, in some localities it is difficult to distinguish from other plants in the genus.
Dudleya saxosasubsp. aloides is a species of perennial succulent plant in the family Crassulaceae known by the common names desert dudleya or desert savior. It is a rosette-forming species widely distributed throughout the Peninsular Ranges and desert mountains of California in the United States. It is characterized by bright-yellow or greenish-yellow flowers, and can be found in shaded crevices and slopes. Plants in western half of the range may grade into Dudleya lanceolata.
Dudleya cymosasubsp. cymosa is a species of succulent perennial plant in the family Crassulaceae native to California.
