ORCHID FAMILY

THE ORCHID FAMILY(Orchidaceae)

Orchidaceae is a diverse and widespread family of flowering plants with blooms that are often colourful and fragrant. Along with the Asteraceae, they are one of the two largest families of flowering plants, with between 21,950 and 26,049 currently accepted species. The name comes from the Ancient Greek ὄρχις (órkhis), literally meaning "testicle", because of the shape of the root.

The family also includes Vanilla (the genus of the vanilla plant), Orchis (type genus), and many commonly cultivated plants such as Phalaenopsis and Cattleya. Moreover, since the introduction of tropical species in the 19th century, horticulturists have produced more than 100,000 hybrids and cultivars.

Orchidaceae are cosmopolitan, occurring in almost every habitat apart from glaciers. The world's richest concentration of orchid varieties is found in the tropics, mostly Asia, South America and Central America, but they are also found above the Arctic Circle and in southern Patagonia.

Like most monocots, orchids generally have simple leaves with parallel veins. The structure of the leaves corresponds to the specific habitat of the plant. Species that typically bask in sunlight, or grow on sites which can be occasionally very dry, have thick, leathery leaves covered by a waxy cuticle to retain their necessary water supply. Shade species, on the other hand, have elongated, thin leaves.

Some orchids have single flowers, but most have an inflorescence, sometimes with a large number of flowers. The flower tepals typically comprise three sepals and three petals. One petal, called the lip or labellum, is typically quite different from the other two. As an orchid flower bud develops, the lip is usually uppermost. In most cases, the flower stem twists to present the lip pointing down by the time the flower opens. This condition is referred to as resupinate. (Resupinate means being upside-down, supine, facing upward.) In the great majority of orchids, the anthers (male structures), carry two pollinia. (A pollinium is a waxy mass of pollen grains held together by the glue-like alkaloid viscin.) Each pollinium is connected to a viscidium, a sticky pad which enables it to stick to the body of pollinators.

The complex mechanisms which orchids have evolved to achieve cross-pollination were investigated by Charles Darwin and described in his 1862 book Fertilisation of Orchids. Orchids have developed highly specialized pollination systems, thus the chances of being pollinated are often scarce. For this reason, orchid flowers usually remain fresh and receptive for very long periods and this is also why most orchids deliver pollen in a single mass. Pollinators are often visually attracted by the shape and colours of the labellum. In some, it is adapted to have a colour, shape and odour mimicking the receptive female of a particular species of insect, often bees. Pollination happens as the insect attempts to copulate with the flowers.

The ovary typically develops into a capsule that is dehiscent (splits open when ripe) by three or six longitudinal slits, while remaining closed at both ends (like the vanilla pod). The seeds are generally almost microscopic and very numerous, in some species over a million per capsule. After ripening, they blow away like dust particles or spores. They lack endosperm (stored food for the development of the embryo) and must enter symbiotic relationships with various fungi that provide them the necessary nutrients to germinate. All orchid species are reliant upon fungi during germination to complete their life cycles. As the chance for a seed to meet a fitting fungus is very small, only a minute fraction of all the seeds released grow into adult plants.

(Monocots are one of two major groups of flowering plants, characterized as having only one seed leaf (cotyledon) in the embryonic form. (monocotyledon=one cotyledon). This group embraces the narrow-leaved, parallel-veined plants with floral symmetry in 3’s or multiples. It also includes grasses and reeds. Its embryonic development differs from the other major group – the dicots (dicotyledon=two cotyledons) that include the broad-leaved, network veined plants with floral symmetry in 4’s or 5’s. Dicots have 2 seed-leaves in the embryonic form.)

Green-winged Orchid
Orchis morio; syn. Anacamptis morio
Other common name(s):
German name(s): Kleines Knabenkraut
ITIS Serial #: 894643
Date:
27 april, 2011

This is a protected flower!

It is a native of western Eurasia, ranging from Europe to Iran.. It grows in grassy meadows, especially on limestone-rich soil and may reach a height of 30 cm.

Leaves are lanceolate, or sometimes ovate, and grow in a rosette around the base of the plan, with some thinner leaves clasping the stem and sheathing almost up to the flowers. Leaves are green and unspotted.

It flowers from April to June The inflorescence is of various colours, mainly purple but ranging from white, through pink, to deep purple. From 5 to 25 helmet-shaped flowers grow in a loose, linear bunch at the top of the single stalk.

The name morio is derived from the Greek word "moros" meaning "fool". This refers to the colorful, green striped flowers. A pair of lateral sepals with prominent green, occasionally purple veins extend laterally like "wings", giving the orchid its name. The broad, three lobed, lower petal is pale in the centre with dark spots.

Protected flower!

This is the largest of the orchids found in the Lobau and the one with the most distinctive flower. It grows to a height of 20 to 50 cm with a robust stem with rather drawn up oblong basal leaves. The inflorescence forms a purplish dense cone consisting of from 10 to 40 flowers. In each flower the sepals and side petals are gathered together to form a pointed "helmet" (whence it gets its name), a lilac colour outside and a veined purple colour inside. The central tongue finishes in two lobes separated by a tooth.

Bug Orchid
Orchis coriophora, syn. Anacamptis coriophora, syn. Anteriorchis coriophora
Other common name(s):
German name(s): Wanzen-Knabenkraut
ITIS Serial #:
Date:
24 May, 2015

Like all types of orchid growing in this area, the Bug Orchid is an endangered and strictly protected species.

As the multiple synonyms suggest, its exact classification is a matter of ongoing discussion but I have chosen to use the name Orchis because that is the one used in the database of the Natural History Museum in Vienna.

It differs from the other orchids growing at the same time in the same area mainly by its colour (a brownish pink) and the shape of the lip petal. The dark pinkish-brown edges are noticeably pulled backwards, emphasising a prominent and lighter-coloured spotted bump. The hood is beak-shaped with a pointed, downward-facing tip.

The elongated, unspotted leaves form a rosette with several smaller and shorter leaves extending from the erect, light green stem.

Beneath each flower in the spike is an upward-reaching, long, narrow, brownish-green bract that is clearly visible in the inflorescence. The spike is cylindrical composed of 15 to 40 small, densely-arranged flowers.

Other common name(s):
German name(s): Fleischfarbenes Knabenkraut, Steifblättriges Knabenkraut
ITIS Serial #: 505935
Date:
24 May, 2015

An endangered and protected species!

This type of orchid is recognisable by its upright, cone-shaped spike of up to 50 dense, pale pink or flesh-coloured flowers with long, pinkish-green bracts reaching upwards between them. The lip is only slightly lobed and appears elongated as its lateral edges are slightly curled under. The darker markings on the lip are distinct, looped and linear, slightly patchy or spotted. There may be considerable variation here. The hood has 2 pink, wing-like sepals projecting outwards and upwards on either side giving the flower a distinctive appearance of flight.

4 to 7 pale green upright leaves reach beyond the base of the flower spike and loosely enfold it, the tips sometimes bending outwards.

This flower tends to hybridise with other related sub-species so many small variations may occur that make it difficult or impossible to identify exactly.

Bee orchid
Ophrys apifera
Other common name(s):
German name(s): Bienen-Ragwurz
ITIS Serial #:
Date:
06 June, 2016

This orchid is particularly rare in Austria and strictly protected.

It is a short lived perennial, producing a small rosette of leaves in the autumn. It develops slowly during 3 - 4 years before producing a flower. It may then flower during several further successive years, then either disappear or miss a few seasons before flowering again. Overall, the numbers of flowering plants in an area may vary greatly from season to season.

The flower attracts bees by producing a scent that mimics the scent of the female bee. In addition, the lip acts as a decoy as the male bee confuses it with a female. Pollen transfer occurs during the ensuing pseudocopulation. Alternatively it can pollinate itself, the stalks of the pollinia bending over causing them to touch the sticky surface of the stigma beneath.

The future seed pod is visible during flowering as a thickened green area behind the flower, growing out from the main stem in the axil of a leaf. This is not a stalk but the female part of the flower.

Violet Limodore
Limodorum abortivum
Other common name(s):
German name(s): Violetter Dingel
ITIS Serial #:
Date:
06 June, 2016

This plant is rare and strictly protected.

It is native to central and eastern Europe, western Asia and the Mediterranean area.

It is easily distinguishable by its strong, upright stem, apparent lack of leaves and large winged flowers. In fact the leaves are in the form of greenish scales sheathing the stem and, although they do photosynthesise, the plant is unable to produce all the food it needs and is largely dependent on a symbiotic or parasitic relationship with its root fungus from which it obtains essential nutrients.

The flowers produce nectar and may either be pollinated by insects or self pollinated.

Seeds are among the largest produced by orchids and seedlings develop very slowly, remaining entirely below ground for 8-10 years before flowering.

Marsh Orchid
Epipactis palustris
Other common name(s): Marsh Helleborine
German name(s): Sumpf-Stendelwurz, Sumpfwurz
ITIS Serial #: 565168
Date:
23 June, 2014

This is a protected flower!

It is a perennial plant, overwintering as rhizomes that produce many shoots, resulting in the spreading of clumps over larger areas.

The tall, erect spikes with loosely arranged flowers have a fragile appearance, the colours delicate and the flower structure not immediately evident when seen from above on account of the downward facing growth. The flower buds are pointed, brownish and also downward facing.

The plants prefer a damp and sunny location, here in an intermittently marshy backwater area.

Broad-leaved Helleborine
Epipactis helleborine
Other common name(s): Broadleaf Helleborine
German name(s): Breitblatt-Ständelwurz
ITIS Serial #: 43482
Date:
10 July, 2015

This is a strictly protected plant as are all the native orchids.

It is found in woods and shady hedge banks as its fungal partner (see explanation at head of page) is also a partner of certain trees and shrubs. It has rhizomes that permit vegetative reproduction in addition to seed production.

The leaves are broad and pointed at the tip with clear parallel veins and spread out flatly, increasing in size towards the base.

Although the flower stem is tall and erect, it is easily overlooked because the petals and sepals are greenish in colour, sometimes with a cream or purple tinge. Only the inside of the deep cup-shaped lip is dark purple. The flowers are numerous, from 15 to 50, and tend to droop. They have no spur but a swollen part at the base that later develops into a pod, each producing as many as 10,000 tiny seeds that are so small, they float in the air and may reach as far as 10 km in the wind before they finally sink to the ground. The fruit pods ripen between August and September.

Bees are the best pollinators as the pollinium sticks well to their fur. Some insects such as wasps and flies visit the flower for its nectar but don’t contribute to pollination as the pollinium doesn’t stick to their smaller, smoother bodies.

Studies have found that the nectar contains minute amounts of oxycodone, an opiate-like narcotic substance.

Lesser Butterfly-Orchid
Platanthera bifolia
Other common name(s): Butterfly Orchid
German name(s): Zweiblättrige Waldhyazinthe, Weiße Waldhyazinthe, Kuckucksblume
ITIS Serial #:
Date:
13 June, 2016

Protected species

The lip of this white orchid is strap-like and 6-10mm long, the other two petals are smaller, upwards-pointing and, together with the upper petal-like sepal (tepal), forms a loose triangular hood that protects the two large pollen packets (pollinia) beneath. The whole flower resembles an insect in flight.

In the evening the flower emits a strong scent that attracts certain species of moths. The moth seeks to reach the nectar stored in the long spur projecting behind the flower, rests its legs on the lip of the flower, pushes its long proboscis between the two pollinia and dislodges them. Their sticky pads then adhere to the body of the insect which will later deposit them onto another flower of the same species.

As with all orchids, the tiny seeds of this flower possess no food reserves and germination is only possible with the help of a root fungus (Mycorhizza).

Sword-leaved Helleborine
Cephalanthera longifolia
Other common name(s): Narrow-Leaved Helleborine
German name(s): Waldvöglein
ITIS Serial #:
Date:
14 May, 2012

Rare in this part of Europe, this is a protected plant.

This orchid has smooth, erect multiple stems. The leaves are dark green, long and narrowly tapering.

The yellow patch on the labellum attracts insects although the flower produces little nectar. The pollen packets, which are the two pollinia suspended above the lip, stick to the backs of solitary bees that visit.

The fruit is a dry capsule and the dust-like seeds are dispersed by the wind.

The perennial plant has a rhizome and can also reproduce vegetatively.
