Thelymitra rubra, commonly called the salmon sun orchid, is a species of orchid endemic to southeastern Australia. A slender species, about 1 foot high. Leaf linear, hardly 5 inches. Bracts very narrow, stems clasping. Flowers one or two, bright red. Petals and sepals ovate-acute, about 5 lines. Column about 3 lines, produced above and behind the anther, but not hooded, slightly denticulate between the lateral appendages. Lateral appendages lanceolate, produced horizontally beyond the anther almost to a point, not ciliate, but covered on both sides densely with rugose glands. Anther obtuse, continuing to enclose the pollen masses behind the stigma, but produced over it. This species is closely related to T. carnea, but the flowers are much larger and of a brighter colour. It opens constantly, is evidently not so absolutely self-fertilising, and is easily distinguished by the large and rugose lateral appendages of the column. - https://en.wikipedia.org/wiki/Thelymitra_rubra
Caladenia tentaculata, commonly known as the eastern mantis orchid, large green-comb, green comb or fringed spider orchid is a plant in the orchid family Orchidaceae and is endemic to south-eastern Australia. It is a ground orchid with a single, hairy leaf and up to three green flowers with red stripes on the sepals and petals. Caladenia tentaculata is a terrestrial, perennial, deciduous, herb with an underground tuber and a single hairy leaf, 80-150 mm long and 12-20 mm wide and often with red spots near the base. Up to three green flowers with red stripes and 60-100 mm across are borne on a spike 150-500 mm tall. The sepals have brown or yellow, club-like glandular tips 5-12 mm long. The dorsal sepal curves forward and is 60-80 mm long and 2-4 mm wide. The lateral sepals are 60-80 mm long, 4-5 mm wide and are turned downward, nearly parallel to each other but with the tips turning to horizontal or slightly upwards, then often drooping at their ends. The petals are 40-50 mm long, 2-3 mm wide and turned downwards. The labellum is green with a white central area and a dark red tip, and is 16-20 mm long and 20-25 mm wide. Each side of the labellum has between five and eight thin green teeth up to 8 mm long and the tip is curved downwards. There are four crowded rows of dark red, club-shaped calli up to 2 mm long in the centre of the labellum. Flowering occurs from September to December. The eastern mantis orchid is widespread through Victoria, eastern New South Wales and south-eastern South Australia, growing in heath, woodland and forest. - https://en.wikipedia.org/wiki/Caladenia_tentaculata
Leptoceras menziesii, commonly known as rabbit orchid, is a plant in the orchid family, Orchidaceae and the only member of the genus Leptoceras. It is a slender plant, usually found in large colonies and which only flowers after fire. The flowers are small, white, pink and red on a stem up to 30 cm (10 in) tall and is endemic to southern Australia. It was one of the first orchids from Western Australia to be described and was given the name Caladenia menziesii, a name still used by some authorities. The rabbit orchid is a tuberous perennial herb growing to a height of 6–20 cm (2–8 in), sometimes 30 cm (10 in) with one to three flowers. The leaf is glabrous, variable in size and shape but mostly lance-shaped to broadly egg-shaped to oblong, 30–120 mm (1–5 in) long and 5–23 mm (0.2–0.9 in) wide. There are one to three small flowers, sometimes all white but more usually white, pink and red. The top sepal at the back of the flower is about 11 mm (0.4 in) long, dark reddish, spoon-shaped and forms a hood over the column. The back of the dorsal sepal has many glandular hairs. The lower, lateral sepals are white or pink, wide in the middle, taper towards both ends and 10–15 mm (0.4–0.6 in) long. The petals forming the "ears" are erect, purplish-red, very narrow linear in shape but club-shaped on the ends, 16–30 mm (0.6–1 in) long and have many glandular hairs. The central labellum is white with pink or red markings, egg-shaped to almost circular, about 7 mm (0.3 in) long and has a short claw. The labellum has 2 to 4 rows of calli with large heads. The column is erect with wide wings and pink markings. The flowers only appear after recent bushfires, in August to November, delayed in some places until after rainfall. Caladenia menziesii was one of the first three orchids collected in Western Australia. Archibald Menzies was the collector of the holotype at King George Sound in 1791 during the Vancouver Expedition. It was first formally described by Robert Brown and the description was published in Prodromus Florae Novae Hollandiae et Insulae Van Diemen. In 1840, John Lindley changed the name to Leptoceras menziesii in The Genera and Species of Orchidaceous Plants. Some herbaria continue to use the old name. The specific epithet ("menziesii) honours Archibald Menzies. Rabbit orchid forms colonies using vegetative reproduction in a range of soil types in heath, scrub or forest, mainly in damp areas. It is widely distributed in Victoria, Tasmania, southern South Australia and the south-west of Western Australia. - https://en.wikipedia.org/wiki/Leptoceras
