CYMBIDIUM

Cymbidium, or boat orchids, is a genus of 52 evergreen species in the orchid family Orchidaceae. One of its first descriptions come from Olof Swartz in 1799. The name is derived from the Greek word kumbos, meaning 'hole, cavity'. It refers to the form of the base of the lip. The genus is abbreviated Cym in horticultural trade.

This genus is distributed in tropical and subtropical Asia (such as northern India, China, Japan, Malaysia, the Philippines, and Borneo) and northern Australia. The larger flowered species from which the large flowered hybrids are derived, grow at high altitudes. 

Cymbidiums became popular in Europe during the Victorian era. One feature that makes the plant so popular is the fact that it can survive during cold temperatures (as low as 7˚C).

PANSY ORCHID

Miltonia, abbreviated Milt. in the horticultural trade, is an orchid genus formed by nine epiphyte species and eight natural hybrids inhabitants of the Brazilian Atlantic Forest, one species reaching the northeast of Argentina and east of Paraguay. This genus was established by John Lindley in 1837, when he described its type species, Miltonia spectabilis. Many species were attributed to Miltonia in the past, however, today, the species from Central America and from cooler areas on northwest of South America have been moved to other genera.

Miltonia species have large and long lasting flowers, often in multifloral inflorescences. This fact, allied to being species that are easy to grow and to identify, make them a favourite of orchid collectors all over the world. Species of this genus are extensively used to produce artificial hybrids. Despite the fact that Miltonia is now a well established genus, most of its species were originally classified under other genera as Cyrtochilum, Oncidium, Odontoglossum, and Brassia. All were discovered between 1834 and 1850 with the exception of M. kayasimae, discovered only in 1976. 

These epiphytic orchids occur from Central to Southern Brazil down to Argentina. They are named after Charles Wentworth-Fitzwilliam, 5th Earl Fitzwilliam, formerly Viscount Milton, an English orchid enthusiast. These orchids have two leaves, arising from a pseudobulbs, covered with a foliaceous sheath. The inflorescence consists of waxy, nonspurred flowers. The lip is large and flat and lacks a callus at its base. They possess a footless column with two hard pollinia. The flowers have a delicate, exotic scent, some compare to that of roses. The species in this genus are sometimes referred to as the "pansy orchids", but it is the Miltoniopsis orchids that have flowers that closely resemble the pansy. Almost everyone except for the most serious orchid hobbyists use the name pansy orchids interchangeably, which may cause confusion.

CALADENIA

Caladenia maritima, commonly known as coastal fingers or Angahook pink fingers, is a species of orchid (family Orchidaceae) endemic to Victoria, Australia. It has a single, almost hairless leaf and one or white flowers with greenish backs and only occurs in the coastal district of Anglesea, Victoria, Australia.

Caladenia maritima is a terrestrial, perennial, deciduous, herb with an underground tuber and a single, almost glabrous, linear leaf, 60–150 mm long and 1–3 mm wide. One or two white flowers 20–25 mm long and wide are borne on a stalk 100–200 mm tall. The backs of the sepals and petals are greenish with a dark line along the centre. The dorsal sepal is erect, sometimes curving backwards and is 10–15 mm long and 2–3 mm wide. The lateral sepals are 13–17 mm long, 4–5 mm wide and spreading. The petals are 13–15 mm  long and 4–5 mm wide and arranged like the lateral sepals. The labellum is 7–9 mm long, 5–8 mm wide and white with purple lines and blotches. The tip of the labellum is orange and curled under. The sides of the labellum have a few narrow teeth near the tip and there are two short rows of yellow or white calli in the centre of the labellum.

Flowering occurs from September to October. This orchid was first described in 1999 by David Jones from a specimen collected near Anglesea and the description was published in The Orchadian. The specific epithet (maritima) is a Latin word meaning "of the sea". Coastal fingers occurs near Anglesea in a single population, growing in woodland with a heathy understorey. 

Caladenia maritima is not classified under the Victorian Government Flora and Fauna Guarantee Act 1988 or under the Australian Government Environment Protection and Biodiversity Conservation Act 1999 but has been listed as "endangered" in Victoria according to the Advisory List of Rare or Threatened Vascular Plants in Victoria – 2004.

PINK SUN ORCHID

Thelymitra carnea, the pink sun orchid, is a perennial herb with fleshy egg-shaped tubers in the Orchidaceae family. It grows from 8 to 40 cm and has a slender reddish-brown stem. Plants are scattered. It has an erect single narrow to rounded channelled leaf 4-18cm x 1-2.5mm, green with reddish base, sheathing at base of stem; 2-3 sheathing stem bracts. 

Each plant has one to four pink flowers up to 15mm across. Sepals and petals are similar. Column pale pink, mid lobe with pink collar and yellow tip, short, narrow, not hooded; yellow column arms narrow, obliquely erect, margins scalloped; anther green. It flowers October to November. The plant grows in moist soils which dry out in summer on margins of swamps. It prefers full sun to semi shade. Flowers only open on hot humid days, self-pollinating in cooler weather.

It is found in Southeastern Australia and New Zealand. It is not threatened in the wild. The use of native orchids in gardens is not recommended, unless they already occur naturally, in which case they need to be protected. Removing orchids from the bush usually results in their death and further depletes remaining wild orchid populations. Take only photographs, not plants from the bush!

CATTLEYA

Perhaps no other orchid surpasses the Cattleya in popularity amongst orchid fanciers around the world. And it is the Cattleya which means "orchid" to the lay person, if they are asked to think about orchid types. It is the Cattleya which has been the mainspring of the orchid industry and it is the Cattleya which has done most to stimulate interest in orchid growing as a hobby.

Cattleya is a genus of 113 species of orchids from Costa Rica and the Lesser Antilles south to Argentina. The genus was named in 1824 by John Lindley after William Cattley who received and was the first to bloom a specimen of Cattleya labiata. William Swainson had discovered the new plant in Pernambuco, Brazil, in 1817 and shipped to the Glasgow Botanic Gardens for identification. Swainson requested that a few plants be later sent to Cattley, who was able to bloom one a full year before the plants in Glasgow.

These orchids are widely known for their large, showy flowers, and were used extensively in hybridisation for the cut-flower trade until the 1980s when pot plants became more popular. The flowers of the hybrids can vary in size from 5 cm to 15 cm or more. They occur in all colours except true blue and black. Many of these species and hybrids are very fragrant. 

The specimen below is a Cattleya mossiae hybrid and is fragrant. The typical flower has three rather narrow sepals and three usually broader petals: Two petals are similar to each other, and the third is the quite different conspicuous lip, featuring various markings and specks and an often frilly margin. At the base, the margins are folded into a tube. Each flower stalk originates from a pseudobulb. The number of flowers varies; it can be just one or two, or sometimes up to ten.

ORCHID

The orchid family, Orchidaceae, is a diverse and widespread family of flowering plants, with blooms that are often colourful and fragrant. Along with the Asteraceae (daisy family), they are one of the two largest families of flowering plants. The Orchidaceae have about 28,000 currently accepted species, distributed in about 763 genera.

The determination of which family is larger is still under debate, because verified data on the members of such enormous families are continually in flux. Regardless, the number of orchid species nearly equals the number of bony fishes and is more than twice the number of bird species, and about four times the number of mammal species. Moreover, since the introduction of tropical species into cultivation in the 19th century, horticulturists have produced more than 100,000 hybrids and cultivars!

Below is Phalaenopsis first described by Blume (1825), also known as moth orchids, abbreviated Phal in the horticultural trade. This is an orchid genus of approximately 60 species. Phalaenopsis is one of the most popular orchids in the trade, through the development of many artificial hybrids. It is native to southern China, the Indian Subcontinent, Southeast Asia (Thailand, Philippines, Malaysia, Indonesia, etc.), New Guinea, the Bismarck Archipelago, and Queensland.
