Halgania cyanea, commonly known as rough halgania, [2] is a species of flowering plant in the family Boraginaceae. It is a small perennial shrub with dull green leaves, bright blue flowers and is endemic to Australia.
Halgania cyanea is a small, usually dense perennial, growing up to 20–40 cm (7.9–15.7 in) high and a spreading habit up to 2 m (6 ft 7 in) wide. The dull green leaves are narrow elliptic or linear shaped, 4–20 mm (0.16–0.79 in) long and 20–40 mm (0.79–1.57 in) wide, flattened, glandular hairs on the upper surface, toothed edges and almost sessile. The bright blue or rarely white flowers 10–12 mm (0.39–0.47 in) in diameter, usually singly or up to 3 in a cluster in a terminal inflorescence on a pedicel 2–10 mm (0.079–0.394 in) long, calyx 3–4 mm (0.12–0.16 in) long, lobes narrow-triangular or lance-shaped, equal in size. It mostly flowers in summer or sporadically throughout the year. The fruit is a brown drupe containing one or two seed. [2] [3] [4]
Halgania cyanea was first formally described in 1840 by John Lindley and the description was published in A Sketch of the Vegetation of the Swan River Colony . [5] [6] The specific epithet (cyanea) means "dark blue". [7]
Rough halgania occurs in a wide range of situations including sandy loam, sand plains, mallee and sand dunes in Western Australia, South Australia, Victoria and the Northern Territory, but is restricted to mallee communities in New South Wales. [8] [9]
Banksia stuposa is a species of shrub that is endemic to the southwest of Western Australia. It has hairy stems, broadly linear pinnatifid leaves, golden yellow and white flowers in heads of one hundred or more, and hairy, egg-shaped follicles.
Caladenia marginata, commonly known as the white fairy orchid, is a species of orchid endemic to the south-west of Western Australia. It has a single pale green, hairy leaf and up to four creamy-white flowers and often grows in dense colonies, flowering profusely after summer fires.
Diuris corymbosa, commonly called common donkey orchid or wallflower orchid, is a species of orchid which is endemic to the south-west of Western Australia. It is similar to the purple pansy orchid but its flowers are yellow rather than purple or mauve and it flowers earlier in the year. It also resembles the winter donkey orchid but flowers later than that species. It is one of the most common orchid species in the Perth area, often forms extensive colonies and usually has numerous flowers on the one spike.
Diuris porrifolia, commonly called the small-flowered donkey orchid is a species of orchid which is endemic to the south-west of Western Australia. It has two or three leaves and up to seven yellow flowers with brown or reddish markings. It is similar to the common donkey orchid but its flowers are smaller and it has a more easterly distribution.
Pterostylis barbata, commonly known as the western bearded greenhood or bird orchid is a species of orchid endemic to the south-west of Western Australia. Flowering plants have a rosette of leaves at the base of the plant and a single translucent white flower with dark green veins on a flowering stem with up to 20 stem leaves. It is one of a number of bearded orchids, some of which have yet to be formally described, all of which have a distinctive feather-like labellum.
Thelymitra cyanea, commonly known as the veined sun orchid in Australia and as the swamp sun orchid or striped sun orchid in New Zealand, is a species of orchid which is native to New Zealand and south-eastern Australia. It has a single erect, fleshy, channelled leaf and up to five bright blue flowers with darker blue veins. It is usually found growing in swamps, sphagnum bogs, and subalpine herbfields, often in clonal colonies.
Thelymitra antennifera, commonly called the rabbit-eared sun orchid, lemon-scented sun orchid or vanilla orchid is a species of orchid which is native to Western Australia, South Australia and Victoria and northern parts of Tasmania.
Calectasia cyanea, commonly known as the star of Bethlehem or blue tinsel lily, is a plant in the family Dasypogonaceae growing as a perennial herb and is endemic to the south–west of Western Australia. Restricted to a single population in Torndirrup National Park, it is critically endangered.
Conostylis aurea, commonly known as golden conostylis, is a plant in the bloodwort family Haemodoraceae. It is endemic to the south-west of Western Australia.
Johnsonia pubescens, commonly called the pipe lily, is a grass-like plant in the family Asphodelaceae, subfamily Hemerocallidoideae, endemic to the south-west of Western Australia. As with others in the genus, it is distinguished by its minute flowers which are on the end of a spike and hidden by large, overlapping, papery bracts.
Caladenia discoidea, commonly known as the dancing spider orchid, antelope orchid or bee orchid is a species of orchid endemic to the south-west of Western Australia. It is distinguished by its horizontally arranged flowers and unusually short sepals and petals.

Pterostylis scabra, commonly known as the green-veined shell orchid, is a species of orchid endemic to the south-west of Western Australia. As with similar orchids, the flowering plants differ from those which are not flowering. The non-flowering plants have a rosette of leaves but the flowering plants lack a rosette and have a single flower with leaves on the flowering spike. This greenhood has a white flower with green and pale brownish-fawn stripes and a long, curved protruding labellum. It is found in inland areas between Kalbarri and Esperance.
Microtis atrata, commonly known as the swamp mignonette orchid or yellow onion orchid and sometimes as Microtidium atratum, is a species of orchid endemic to southern Australia. It has a single thin leaf and up to forty or more yellowish-green flowers. The flowers are the smallest of any Australian ground-dwelling orchid. The orchid usually grows in large colonies after fire and although small, are easily seen because of their very large numbers in their blackened surroundings.
