Lawrencella rosea

Lawrencella is a genus of flowering plants in the family Asteraceae endemic to Australia.

The genus comprises two species: Lawrencella davenportii with a distribution in arid regions of Western Australia, The Northern Territory, and South Australia and Lawrencella rosea which is restricted to Southern Western Australia. [3]

Both species are annual herbs growing to approximately 40 cm in height. The strap-shaped leaves up to 10 cm in length are covered with short hairs. Flower heads are produced on stalks well above the main leaves, and have yellow centres with pink or occasionally white bracts. Flowering usually occurs in spring or summer in years with good cool season rain. [4] [5]

Both species have horticultural potential for their colourful flower displays and their drought hardiness. However, difficulties in germination of seed have restricted their widespread cultivation to date. [5] [6]

The genus Lawrencella is closely related to two other Australian genera, Schoenia and Bellida .

The family Asteraceae, alternatively Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales. Commonly referred to as the aster, daisy, composite, or sunflower family, Compositae were first described in the year 1740. The number of species in Asteraceae is rivaled only by the Orchidaceae, and which is the larger family is unclear as the quantity of extant species in each family is unknown.

Amaryllis is the only genus in the subtribe Amaryllidinae. It is a small genus of flowering bulbs, with two species. The better known of the two, Amaryllis belladonna, is a native of the Western Cape region of South Africa, particularly the rocky southwest area between the Olifants River Valley and Knysna.

<i>Helichrysum</i> Genus of flowering plants

The genus Helichrysum consists of an estimated 600 species of flowering plants in the sunflower family (Asteraceae). The type species is Helichrysum orientale. They often go by the names everlasting, immortelle, and strawflower. The name is derived from the Anicent Greek words ἥλιος and χρῡσός.

<i>Gundelia</i> Genus of flowering plants

Gundelia is a low to high (20–100 cm) thistle-like perennial herbaceous plant with latex, spiny compound inflorescences, reminiscent of teasles and eryngos, that contain cream, yellow, greenish, pink, purple or redish-purple disk florets. It is assigned to the family Asteraceae. Flowers can be found from February to May. The stems of this plant dry-out when the seeds are ripe and break free from the underground root, and are then blown away like a tumbleweed, thus spreading the seeds effectively over large areas with little standing vegetation. This plant is native to the eastern Mediterranean and the Middle-East. Opinions differ about the number of species in Gundelia. Sometimes the genus is regarded monotypic, Gundelia tournefortii being a species with a large variability, but other authors distinguish up to nine species, differing in floret color and pubescence. Young stems are cooked and eaten in the Middle-East and are said to taste like a combination of artichoke and asparagus. The plant also contains compounds that have been demonstrated to be effective against a range of ailments. A large quantity of pollen assigned to Gundelia has been found on the Shroud of Turin, which may suggest that the crown of thorns was made from Gundelia, but this finding has been contested.

Gerbera is also commonly known as the African daisy.

<i>Byblis</i> (plant) Genus of carnivorous plants

Byblis is a small genus of carnivorous plants, sometimes termed the rainbow plants for the attractive appearance of their mucilage-covered leaves in bright sunshine.

Eight species are now recognized.

<i>Xerochrysum bracteatum</i> Flowering plant in the family Asteraceae native to Australia

Xerochrysum bracteatum, commonly known as the golden everlasting or strawflower, is a flowering plant in the family Asteraceae native to Australia. Described by Étienne Pierre Ventenat in 1803, it was known as Helichrysum bracteatum for many years before being transferred to a new genus Xerochrysum in 1990. It is an annual up to 1 m (3.3 ft) tall with green or grey leafy foliage. Golden yellow or white flower heads are produced from spring to autumn; their distinctive feature is the papery bracts that resemble petals. The species is widespread, growing in a variety of habitats across the country, from rainforest margins to deserts and subalpine areas. The golden everlasting serves as food for various larvae of lepidopterans, and adult butterflies, hoverflies, native bees, small beetles, and grasshoppers visit the flower heads.

<i>Chrysocephalum semipapposum</i> Species of plant

Chrysocephalum semipapposum, commonly known as clustered everlasting is a perennial shrub native to Australia. Clustered everlasting belongs to the family Asteraceae. C. semipapposum produces terminal flowers heads in clusters, mainly between spring and early summer with silver-grey appearing stems and branches. It grows up to 40cm high and 60 cm high, although there have been some varieties which can grow up to 1 m. C. semipapposum is often confused with Chrysocephalum apiculatum or 'yellow buttons', due to their similar appearances. C. semipapposum has 4 different subspecies, however they lack distinctive qualities and are often hard to identify. C. semipapposum is endemic to Australia and can be found in multiple states, most notably within Victoria. The plant is found in a variety of habitats including dry rocky regions. Clustered everlasting often grows sparsely and is rarely found in abundance and can be mistaken for a weed. Clustered everlasting has many uses, including as a source of nectar for butterflies, cut flowers or as an addition to a garden.
