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 alternative name is lilioid monocots.
Lobularia maritima is a species of low-growing flowering plant in the family Brassicaceae. Its common name is sweet alyssum or sweet alison, also commonly referred to as just alyssum.
Eremophila is a genus of more than 270 species of plants in the figwort family, Scrophulariaceae all of which are endemic to mainland Australia.. Eremophilas are widespread in the arid areas of Australia, especially Western Australia and range in size from low-growing shrubs to small trees. The petals are joined, at least at their bases, into a tube with the upper petals different in size and shape from the lower ones. Some species have common names including emu bush, poverty bush or fuchsia bush, reflecting the belief that emus eat the fruit, their arid environment or a superficial resemblance to the flowers of plants in the genus Fuchsia.
Ophrys insectifera, the fly orchid, is a species of orchid and the type species of the genus Ophrys. It is remarkable as an example of the use of sexually deceptive pollination and floral mimicry, as well as a highly selective and highly evolved plant–pollinator relationship.
Paeonia brownii is a low to medium height, herbaceous perennial flowering plant in the family Paeoniaceae. It has compound, steely-gray, somewhat fleshy leaves and small drooping maroon flowers. Its vernacular name is Brown's peony, native peony or western peony. It is native to the western United States and usually grows at altitude, often as undergrowth in part-shade. The fleshy roots store food to carry the plant through the dry summers and produce new leaves and flowers the following spring.
Platystemon is a monotypic genus of flowering plants in the poppy family containing the single species Platystemon californicus, which is known by the common name creamcups. It is native to Oregon, California, Arizona, Utah and Baja California, and is found in open grasslands and sandy soils below 6,000 feet (1,800 m) elevation.
Commelina communis, commonly known as the Asiatic dayflower, is an herbaceous annual plant in the dayflower family. It gets its name because the blooms last for only one day. It is native throughout much of East Asia and northern parts of Southeast Asia. In China, the plant is known as yazhicao, roughly translating to "duckfoot herb", while in Japan it is known as tsuyukusa, meaning "dew herb". It has also been introduced to parts of central and southeastern Europe and much of eastern North America, where it has spread to become a noxious weed. It is common in disturbed sites and in moist soil. The flowers emerge from summer through fall and are distinctive with two relatively large blue petals and one very small white petal.
Knautia arvensis, commonly known as field scabious, is a herbaceous perennial species of flowering plant in the honeysuckle family Caprifoliaceae.
Lobelia siphilitica, the great blue lobelia, great lobelia, or blue cardinal flower, is a plant species within the family Campanulaceae. It is an herbaceous perennial dicot native to eastern and central Canada and United States. There are two recognized varieties of Lobelia siphilitica, var. siphilitica and var. ludoviciana. Blooming from August to October, it is short-lived, lasting only for a few years.
Thelymitra crinita, commonly known as the blue lady orchid, queen orchid or lily orchid, is a species of orchid which is endemic to the south-west of Western Australia. It has a single broad, oval leaf and up to fifteen brilliant blue flowers with a blue column with the lobe on top of the anther covered with short, finger-like calli.
Succisa pratensis, also known as devil's-bit or devil's-bit scabious, is a flowering plant in the honeysuckle family Caprifoliaceae. It differs from other similar species in that it has four-lobed flowers, whereas Scabiosa columbaria and Knautia arvensis have five lobes and hence it has been placed in a separate genus in the same family. It also grows on damper ground.
Leucopogon parviflorus, commonly known as coast beard-heath or native currant, is a shrub or small tree in the family Ericaceae. It is native to all Australian states and territories excluding the Northern Territory and the ACT and also grows in New Zealand. The species can grow to between 1 and 5 metres in height and has leaves that are 11 to 29 mm long and 2.4 to 7.5 mm in width, often with curved tips. The white flowers are around 15 mm long and are produced in spikes of 7 to 13. These occur throughout the year.
Calochilus, commonly known as beard orchids, is a genus of about 30 species of plants in the orchid family, Orchidaceae. Beard orchids are terrestrial herbs with a single leaf at the base of the plant, or no leaves. Their most striking feature is a densely hairy labellum, giving rise to their common name. Beard orchids, unlike some other Australian orchids, do not reproduce using daughter tubers, but self-pollinate when cross-pollination has not occurred. Most species occur in Australia but some are found in New Zealand, New Guinea and New Caledonia.
Paeonia broteri is a perennial, herbaceous species of peony. It is an endemic species of the Iberian Peninsula. It bears rose-pink highly fragrant flowers about 12 cm wide and glossy green leaves. It reaches up to 40 centimetres (16 in) in height.
Galearis rotundifolia is a species of flowering plants in the orchid family, Orchidaceae. It is commonly called roundleaf orchis and small round-leaved orchid. It is a succulent perennial herb native to North America, where it occurs throughout Canada, part of the northern United States, and Greenland.
Babiana ambigua is a species of plant in the Iridaceae. It is endemic to the Western Cape province of South Africa. It is a geophyte, that appears from an underground corm every year and grows to a height of 5–8 cm (2.0–3.1 in) or occasionally up to 16 cm (6.3 in). Its leaves are pleated, hairy, lance-shaped, reaching higher than the inflorescence. The fragrant, mirror-symmetric, blue to mauve flowers, consist of six tepals merged into a tube at their base, but with free lobes at the top. The lower lateral tepals have whitish markings accentuated by a more intense blue line along their margin. Each flower is supported by two green bracts sometimes with a brownish tip, and the inner bract is divided entirely to its base. There are three anthers crowded to the dorsal side of the perianth and a style divided in three branches on top of a smooth ovary. Flowers can be found from late July at sea level to the end of September at high altitude.
Gaylussacia frondosa is a species of flowering plant in the heath family known by the common names dangleberry and blue huckleberry. It is native to the eastern United States, where it occurs from New Hampshire to South Carolina.
Pentachondra pumila, also known as carpet heath, is a small alpine shrub in the epacris family (Ericaceae). It is commonly found in Australia and New Zealand in areas of high rainfall, being known for its small white flowers as well as its red, hollow fruit that grows on branch ends. It is distinguishable as a prostrate, mat-like shrub, growing in rocky or boggy alpine areas. The fruit is edible and is a food source for many species of bird.
Rubus flagellaris, the northern dewberry, also known as the common dewberry, is a North American species perennial subshrub species of dewberry, in the rose family. This dewberry is distributed across much of Canada, Mexico, and the United States. It grows in diverse habitats ranging from drier savannas to temperate deciduous forests.
Thelymitra campanulata, commonly called the bell sun orchid or shirt orchid, is a species of orchid in the family Orchidaceae and is endemic to the south-west of Western Australia. It is a common species with a single narrow leaf and up to fifteen distinctly cup-shaped, prominently striped blue or mauve flowers with crowded, finger-like glands on top of the anther.
