Dudleya Guadalupensis
''Dudleya guadalupensis'' is a very rare species of succulent perennial plant in the family Crassulaceae commonly known as the Guadalupe liveforever. It is a rosette-forming leaf succulent, with foliage that is variously colored light green, green, and a waxy white. It is characterized by dense leaves that fold over the center in dormancy, a curving, sinuous flower stalk, and white, cup-shaped flowers. It is endemic to the rocks and islets off of Guadalupe Island, an isolated volcanic island in the Pacific Ocean located 241 kilometers off of the coast of Baja California. Description A densely-leaved species of ''Dudleya'', with the outer foliage folding over the center, giving the rosettes a rounded appearance. It has a curved flower stalk and white flowers that form a cup or "V" shape. Morphology Like most other ''Dudleya'', this plant is a rosette-forming leaf succulent which grows rosettes on the tips of a stem, with the stem also referred to as a caudex. In this speci ...

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), Mo ...

Petal
Petals are modified leaves that surround the reproductive parts of flowers. They are often 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 genera such as '' Aloe'' and '' Tulipa''. Conversely, genera such as ''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. Since they include Liliales, an alte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcanic Cone
Volcanic cones are among the simplest volcanic landforms. They are built by ejecta from a volcanic vent, piling up around the vent in the shape of a cone with a central crater. Volcanic cones are of different types, depending upon the nature and size of the fragments ejected during the eruption. Types of volcanic cones include stratocones, spatter cones, tuff cones, and cinder cones. Stratocone Stratocones are large cone-shaped volcanoes made up of lava flows, explosively erupted pyroclastic rocks, and igneous intrusives that are typically centered around a cylindrical vent. Unlike shield volcanoes, they are characterized by a steep profile and periodic, often alternating, explosive eruptions and effusive eruptions. Some have collapsed craters called calderas. The central core of a stratocone is commonly dominated by a central core of intrusive rocks that range from around to over several kilometers in diameter. This central core is surrounded by multiple generations of lava ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dudleya Virens Subsp
''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 star ...

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 ...

Pinus Radiata
''Pinus radiata'' ( syn. ''Pinus insignis''), the Monterey pine, insignis pine or radiata pine, is a species of pine native to the Central Coast of California and Mexico ( Guadalupe Island and Cedros island). It is an evergreen conifer in the family Pinaceae. ''P. radiata'' is a versatile, fast-growing, medium-density softwood, suitable for a wide range of uses. Its silviculture reflects a century of research, observation and practice. It is often considered a model for growers of other plantation species. It is the most widely planted pine in the world, valued for rapid growth and desirable lumber and pulp qualities. Although ''P. radiata'' is extensively cultivated as a plantation timber in many temperate parts of the world, it faces serious threats in its natural range, due to the introduction of pine pitch canker (''Fusarium circinatum''). Description ''P. radiata'' is a coniferous evergreen tree growing to tall in the wild, but up to in cultivation in optimum condi ...

Feral Goat
The feral goat is the domestic goat (''Capra aegagrus hircus'') when it has become established in the wild. Feral goats occur in many parts of the world. Species Feral goats consist of many breeds of goats, all of which stem from the wild goat, ''C. aegagrus''. Although breeds can look different, they all share similar characteristics. Physically, both domestic and feral goats can be identified by their prominent straight horns (more prominent on male goats), rectangular pupils, and coarse hair. In addition, most domesticated goats/feral goats lie around 100 – 120lbs, with heavier goats tending to be wild goats. Behavior The feral goat is seen in Australia, New Zealand, Ireland, Great Britain, Hawaii, Brazil, Honduras, Lebanon, Panama, Madagascar, Comoro Islands, Mauritius, Réunion, New Guinea, the Galapagos, Cuba and in many other parts of the world. When feral goats reach large populations in habitats which are not adapted to them, they may become an invasive species wi ...
