Heteromeles
''Heteromeles arbutifolia'' (, more commonly by Californian botanists), commonly known as toyon, is a perennial shrub native to Coastal California. It is the sole species in the genus ''Heteromeles''. Description Toyon typically grows from , rarely up to 10 m in shaded conditions, and has a rounded to irregular top. Its leaves are evergreen, alternate, sharply toothed, have short Petiole (botany), petioles, and are in length and wide. In the early summer it produces small white flowers diameter in dense terminal corymbs. Flowering peaks in June. The five petals are rounded. The fruit is a small pome, 5–10 mm across, bright red and berry-like, produced in large quantities, maturing in the fall and persisting well into the winter.

Photinia
''Photinia'' () is a genus of about 30 species of small trees and large shrubs, but the taxonomy has recently varied greatly, with the genera ''Heteromeles'', '' Stranvaesia'' and '' Aronia'' sometimes included in ''Photinia''. They are a part of the rose family (Rosaceae) and related to the apple. The botanical genus name derives from the Greek word ''photeinos'' for shiny and refers to the often glossy leaves. Most species are evergreen, but deciduous species also occur. The small apple-shaped fruit has a size of 4 to 12 mm and forms in large quantities. They ripen in the fall and often remain hanging on the bush until well into the winter. The fruits are used as food by birds, which excrete the seeds with their droppings and thereby distribute the plant. The natural range of these species is restricted to warm temperate Asia, from the Himalayas east to Japan and south to India and Thailand. They have, however, been widely cultivated throughout the world as ornamentals for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Guadalupe Island
Guadalupe Island () is a volcanic island located off the western coast of Mexico's Baja California peninsula and about southwest of the city of Ensenada in the state of Baja California, in the Pacific Ocean. The various volcanoes are extinct or dormant. In 2005 Guadalupe Island and its surrounding waters and islets were declared a biosphere reserve to restore its vegetation (decimated by feral goats) and to protect its population of marine mammals and birds. The island was a popular destination for great white shark cage diving before a tourism ban was put in place in 2022. Guadalupe Island is inhabited only by scientists, military personnel operating a weather station, and a small group of seasonal fishermen. The island is mostly arid and has very little surface water. The two other Mexican island groups in the Pacific Ocean that are not on the continental shelf are the Revillagigedo Islands and Rocas Alijos. Guadalupe Island and its islets are the westernmost region ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Coastal Sage Scrub
Coastal sage scrub, also known as coastal scrub, CSS, or soft chaparral, is a low scrubland plant community of the California coastal sage and chaparral subecoregion, found in coastal California and northwestern coastal Baja California. It is within the California chaparral and woodlands ecoregion, of the Mediterranean forests, woodlands, and scrub biome. Characteristics ;Plant community Coastal sage scrub is characterized by low-growing aromatic, and drought-deciduous shrubs adapted to the semi-arid Mediterranean climate of the coastal lowlands. The community is sometimes called "soft chaparral" due to the predominance of soft, drought-deciduous leaves in contrast to the hard, waxy-cuticled leaves on sclerophyllous plants of California's chaparral communities. ;Flora Characteristic shrubs and subshrubs include: * California sagebrush (''Artemisia californica'') * Black sage (''Salvia mellifera'') * White sage (''Salvia apiana'') * California buckwheat (''Eriogonum fasci ...

Corymb
Corymb is a botanical term for an inflorescence with the flowers growing in such a fashion that the outermost are borne on longer pedicels than the inner, bringing all flowers up to a common level. A corymb has a flattish top with a superficial resemblance towards an umbel, and may have a branching structure similar to a panicle. Flowers in a corymb structure can either be parallel, or alternate, and form in either a convex, or flat form. Many species in the Maloideae, such as hawthorns and rowans, produce their flowers in corymbs. The Norway maple and yerba maté are also examples of corymbs. The word ''corymb'' is derived from the Ancient Greek Ancient Greek (, ; ) includes the forms of the Greek language used in ancient Greece and the classical antiquity, ancient world from around 1500 BC to 300 BC.

Channel Islands (California)
The Channel Islands () are an eight-island archipelago located within the Southern California Bight in the Pacific Ocean, off the coast of California. They define the Santa Barbara Channel between the islands and the California mainland. The four Northern Channel Islands are part of the Transverse Ranges geologic province, and the four Southern Channel Islands are part of the Peninsular Ranges province. Five of the islands are within the Channel Islands National Park. The waters surrounding these islands make up Channel Islands National Marine Sanctuary. The Nature Conservancy was instrumental in establishing the Channel Islands National Marine Sanctuary. There is evidence that humans have lived on the Northen Channel Islands for thousands of years. Radiocarbon dating shows that there was a continuous human presence between 8000-11000 years ago. The islands were inhabited primarily by two different Native American groups, the Chumash, and the Tongva/Gabrieleno .The Chan ...
