Dudleya Cymosa Subsp. Paniculata
''Dudleya cymosa'' subsp. ''paniculata'', known by the common name Diablo Range dudleya, is a species of perennial succulent plant in the family Crassulaceae native to the Inner South Coast Range of California. It is characterized by pale yellowish flowers, oblong to oblanceolate leaves and a growth habit not limited to a single substrate. It is closely related to ''Dudleya abramsii'' subsp. ''setchellii''. Description This plant is not usually caespitose, rosettes are solitary to few. The rosettes are 4 to 11 cm wide. The stems are 1 to 2 cm wide. The leaves are 3 to 10 cm, 5 to 20 mm wide, shaped oblong, oblanceolate to lance-oblong, green to more or less white, and the foliage may or may not be glaucous, leaf tip acute. The peduncle is 5 to 25 cm long, and the inflorescence contains 2 to 3 branches that rebranch once or twice. The terminal branches are 1 to 5 cm long, with 4 to 10 flowers, on pedicels 3 to 12 mm long. The petals are 1.5 ...

Perennial Plant
A perennial plant or simply perennial is a plant that lives more than two years. The term ('' per-'' + '' -ennial'', "through the years") is often used to differentiate a plant from shorter-lived annuals and biennials. The term is also widely used to distinguish plants with little or no woody growth (secondary growth in girth) from trees and shrubs, which are also technically perennials. Perennialsespecially small flowering plantsthat grow and bloom over the spring and summer, die back every autumn and winter, and then return in the spring from their rootstock or other overwintering structure, are known as herbaceous perennials. However, depending on the rigours of local climate (temperature, moisture, organic content in the soil, microorganisms), a plant that is a perennial in its native habitat, or in a milder garden, may be treated by a gardener as an annual and planted out every year, from seed, from cuttings, or from divisions. Tomato vines, for example, live several y ...

Petal
Petals are modified Leaf, leaves that surround the reproductive parts of flowers. They are often advertising coloration, brightly colored or unusually shaped to attract pollinators. All of the petals of a flower are collectively known as the ''corolla''. Petals are usually accompanied by another set of modified leaves called sepals, that collectively form the ''calyx'' and lie just beneath the corolla. The calyx and the corolla together make up the perianth, the non-reproductive portion of a flower. When the petals and sepals of a flower are difficult to distinguish, they are collectively called tepals. Examples of plants in which the term ''tepal'' is appropriate include Genus, genera such as ''Aloe'' and ''Tulipa''. Conversely, genera such as ''Rose, Rosa'' and ''Phaseolus'' have well-distinguished sepals and petals. When the undifferentiated tepals resemble petals, they are referred to as "petaloid", as in petaloid monocots, orders of monocots with brightly colored tepals. Sinc ...

Flora Of California
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ...

Dudleya
''Dudleya'', commonly known as liveforevers (Spanish: ''siemprevivas'') is a genus of succulent plants in the stonecrop family, Crassulaceae, consisting of about 68 taxa in southwestern North America and Guadalupe Island. The species come in multiple divergent forms, some large and evergreen, others cryptic and deciduous, but despite their dramatic variations in appearance, most species readily hybridize. The flowers of ''Dudleya'' have parts numbered in 5, with the petals arranged in tubular, star-shaped, and bell-shaped forms, and when fruiting are filled with tiny, ovoid to crescent-shaped seeds. The genus evolved as neoendemics, from ancestors in the stonecrop genus, ''Sedum.'' The ancestors radiated southward from ''Sedum'' during the creation of the dry summer climate in the California region 5 million years ago. Early botanists classified the larger species as ''Echeveria'' and ''Cotyledon'', while the cryptic species were placed as ''Sedum''. Taxonomic efforts starte ...

Edaphic
Edaphology (from Greek , ''edaphos'', "ground",, ''-logia'') is concerned with the influence of soils on living beings, particularly plants. It is one of two main divisions of soil science, the other being pedology. Edaphology includes the study of how soil influences humankind's use of land for plant growth as well as people's overall use of the land. General subfields within edaphology are agricultural soil science (known by the term agrology in some regions) and environmental soil science. (Pedology deals with pedogenesis, soil morphology, and soil classification.) In Russia, edaphology is considered equivalent to pedology, but is recognized to have an applied sense consistent with agrophysics and agrochemistry outside Russia. History Xenophon (431–355 BC), and Cato (234–149 BC), were early edaphologists. Xenophon noted the beneficial effect of turning a cover crop into the earth. Cato wrote De Agri Cultura ("On Farming") which recommended tillage, crop rotatio ...

Reid Venable Moran
Reid Venable Moran (June 30, 1916 – January 21, 2010) was an American botanist and the curator of botany at the San Diego Natural History Museum from 1957 to 1982. Moran was the world authority on the Crassulaceae, a family of succulent plants, and in particular the genus ''Dudleya'', the subject of his Ph.D. dissertation. He named at least 18 plants new to science — some in that family and some not — and published many papers elucidating relationships within the Crassulaceae. As a mark of the respect he earned among his peers, more than a dozen plants have been named for him. Jane Goodall described Moran as "a sort of living myth in botanical exploration in Baja California and the Pacific Islands of Mexico," citing specifically his analysis of the environmental impact of introduced species (especially goats) on the flora of Guadalupe Island. Biography Born in Los Angeles, California on June 30, 1916 to Edna Louise Venable and Robert Breck Moran (a petroleum geologist), Mora ...

Willis Linn Jepson
Willis Linn Jepson (August 19, 1867 – November 7, 1946) was an early California botanist, conservationist, and writer. Career Born at Little Oak Ranch near Vacaville, California, Jepson became interested in botany as a boy and explored the adjacent San Francisco Bay Area. He came in contact with various botanists before he entered college. In 1892, at the age of 25, Jepson, John Muir, and Warren Olney formed the Sierra Club, in Olney's San Francisco law office. From 1895 to 1898, Jepson served as instructor in Botany and carried on research at the University of California, Berkeley, Cornell University (1895), and Harvard University (1896–1897).

Dudleya Caespitosa
''Dudleya caespitosa'' is a succulent plant known by several common names, including sea lettuce, sand lettuce, and coast dudleya. It is endemic to California, where it grows along the coastline in the southern half of the state. Taxonomically, this species is a highly variable complex of polymorphic and polyploid plants, closely related to numerous neighboring species such as '' Dudleya farinosa'', ''Dudleya greenei'' and ''Dudleya palmeri''. It is delimited from neighboring species on an arbitrary basis of distribution and chromosome number, and may not be immediately separable from the other species it approaches. Description Vegetative morphology This plant may grow in solitary rosettes, but most often forms caespitose clumps, which may contain up to 150+ rosettes. The clumps are generally not dense. Each rosette may be anywhere from 8 to 32 cm wide, containing 15 to 30 leaves. The caudex is 1.5 to 4 cm wide, and on older plants is often exposed between dry ...
