Diuris orientis, commonly called the wallflower orchid or eastern wallflower orchid, is a species of orchid which is endemic to eastern Australia. Like others in the genus Diuris, it has two ear-like petals and is similar to the common donkey orchid (Diuris corymbosa) of Western Australia with which it has been confused. This species is found in New South Wales, Victoria, South Australia and Tasmania and its stalk-like petal "claw" is shorter in than those of D. corymbosa. Diuris orientis is a tuberous, perennial, terrestrial herb, usually growing to a height of 12–35 cm. There are up to three leaves arising from the base of the plant, each leaf linear to narrow lance-shaped, 10–30 cm long, 5–10 mm wide and channelled. There are up to 6 yellow flowers with reddish brown, purplish and mauve markings on a raceme 8–40 mm high. The dorsal sepal is erect, broadly egg-shaped, 9–15 mm long and wide. The lateral sepals are greenish-brown, linear to lance-shaped, 12–23 mm long, 3–4 mm wide, project down below the flow and are parallel or sometimes crossed. The petals are erect and spread, ear-like above the flower. They are broadly egg-shaped, 12–20 mm long, 8–12 mm wide on a greenish-brown, stalk-like "claw", 3–6 mm. (The claw in the similar Western Australian Diuris corymbosa is longer.) The labellum is 10–14 mm long and is divided into three lobes. The lateral lobes are narrow egg-shaped to wedge shaped, 7–11 mm long, 2.5–4 mm wide, sometimes with a wavy margin. The medial lobe is 5–8 mm, wedge-shaped, strongly folded with a rounded tip. There is a callus near the base of the mid-lobe, consisting of a narrow, yellow ridge. Flowering usually occurs between September and November. Diuris orientis was first formally described in 1998 by David Jones from a specimen collected at Beauty Point in Tasmania. The description was published in Australian Orchid Research. The specific epithet (orientis) is a Latin word meaning "east", referring to the easterly distribution of this species, compared to other orchids in the Diuris corymbosa complex. The eastern wallflower orchid is widely distributed in South Australia, Tasmania and Victoria. In New South Wales it is only found in the far south east, in and near the Nadgee Nature Reserve. In Victoria it is fairly common in open forest and heath. There is a dramatic increase in the flowering of this species after summer bushfires. - https://en.wikipedia.org/wiki/Diuris_orientis
Diuris pardina, commonly known as the leopard orchid or leopard doubletail is a species of orchid which is endemic to south-eastern Australia. It has two or three grass-like leaves and up to ten yellow flowers with reddish-brown marks and blotches. Diuris pardina is a tuberous, perennial herb with two or three linear leaves 100–300 mm (4–10 in) long, 4–6 mm (0.2–0.2 in) wide and folded lengthwise. Flowering occurs from August to October. Diuris pardina was first formally described in 1840 by John Lindley and the description was published in his book, The Genera and Species of Orchidaceous Plants. The specific epithet (pardina) is derived from the Ancient Greek word pardos meaning "leopard". The leopard orchid is found in New South Wales, the Australian Capital Territory, Victoria, South Australia and Tasmania. It grows in well-drained soils in heath and forest and there is considerable variation in the colouration of the flowers. In New South Wales in occurs south from Mudgee and in Victoria it is widespread and common in the southern half of the state. - https://en.wikipedia.org/wiki/Diuris_pardina
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
