A shrub or bush is a small-to-medium-sized perennial woody plant. Unlike herbaceous plants, shrubs have persistent woody stems above the ground. Shrubs can be either deciduous or evergreen. They are distinguished from trees by their multiple stems and shorter height, less than 6–10 m (20–33 ft) tall. Small shrubs, less than 2 m (6.6 ft) tall are sometimes termed as subshrubs. Many botanical groups have species that are shrubs, and others that are trees and herbaceous plants instead.
Centaurea is a genus of over 700 species of herbaceous thistle-like flowering plants in the family Asteraceae. Members of the genus are found only north of the equator, mostly in the Eastern Hemisphere; the Middle East and surrounding regions are particularly species-rich. In the western United States, yellow starthistles are an invasive species. Around the year 1850, seeds from the plant had arrived to the state of California. It is believed that those seeds came from South America.
Bromus is a large genus of grasses, classified in its own tribe Bromeae. They are commonly known as bromes, brome grasses, cheat grasses or chess grasses. Estimates in the scientific literature of the number of species have ranged from 100 to 400, but plant taxonomists currently recognize around 160–170 species.
Thistle is the common name of a group of flowering plants characterised by leaves with sharp prickles on the margins, mostly in the family Asteraceae. Prickles can also occur all over the plant – on the stem and on the flat parts of the leaves. These prickles are an adaptation that protects the plant from being eaten by herbivores. Typically, an involucre with a clasping shape similar to a cup or urn subtends each of a thistle's flower heads. The typically feathery pappus of a ripe thistle flower is known as thistle-down.
North Meadow, Cricklade is a hay meadow near the town of Cricklade, in Wiltshire, England. It is 24.6 hectares in size. It is a traditionally managed lowland hay-meadow, or lammas land, and is grazed in common between 12 August and 12 February each year, and cut for hay no earlier than 1 July. This pattern of land use and management has existed for many centuries and has resulted in the species rich grassland flora and fauna present on the site.
Pigeon Island is a small island located need the middle of the Wallabi Group of the Houtman Abrolhos, an archipelago off the coast of Western Australia. It is almost entirely given over to western rock lobster fishers' camps, and as a result is far more disturbed than most other islands in the archipelago. A nearby island also seasonally populated by fishers is named Little Pigeon Island, hence Pigeon Island is sometimes referred to as "Big Pigeon Island".
Atriplex lentiformis is a species of saltbush.
The Blue Oak Ranch Reserve, a unit of the University of California Natural Reserve System, is an ecological reserve and biological field station in Santa Clara County, California. It is located on 3,260 acres (13.2 km2) in the Diablo Range, northwest of Mount Hamilton, at 1,500 ft (460 m) elevation.
Morocco provides a refuge for a rich and diverse flora with about 4,200 taxa, of which 22% are endemic. The phytogeographic zones of Morocco comprise 8 zones: the Mediterranean zone, the Cedar zone (1000-2000m), the sub-Alpine zone (2,000-2,500m), the Alpine zone (2,500m+), the semi-desert scrub zone, the Reg, the sandy desert zone and the oases.
Cirsium perplexans is a species of flowering plant in the family Asteraceae known by the common names Rocky Mountain thistle and Adobe Hills thistle. It is endemic to Colorado in the United States, where it occurs in the Colorado and Gunnison River Valleys in the Rocky Mountains.
The flora of Lebanon includes approximately 2,600 plant species. Situated on the eastern coast of the Mediterranean Basin, Lebanon is a reservoir of plant diversity and one of the world's biodiversity hotspots for conservation priorities. Endemic species constitute 12% of the Lebanese flora; 221 plant species are broad endemics and 90 are narrow endemics. Important Plant Areas (IPAs) featuring the country exceptional botanical richness were defined in 2018.
