Rare Ghost Orchid Has Multiple Pollinators | Short Film Showcase

Deep in remote Florida swamps, a team of researchers and photographers have made a new discovery that upends what we thought we knew about the ghost orchid, one of the world’s most iconic flowers, and how it reproduces.

Rare lizard orchid re-discovered in the Netherlands


This video is called Wild Orchids – Himantoglossum hircinum (lizard orchid).

Game warden Mark Kras of the coastal sand dunes national park in South Holland province reports today that a rare orchid species has been rediscovered there.

It is the lizard orchid. In 1890, this species disappeared from the area. In 1980, it appeared again. Then, no lizard orchids until 2008. Then, gone again. And now, in 2019, it was found not so far from Katwijk town.

Twelve orchid species grow in this national park. The symbol flower of the park is the pyramid orchid.

Tilos orchids, birds and sea


This January 2019 video is called Tilos island, Dodecanese, Greece HD.

After 19 April 2019, we woke up the next day, 20 April, in Megalo Chorio, Tilos island.

In the morning, a singing nightingale.

We climbed the steep village alleys up to a Greek Orthodox church.

Heart, 20 April 2019

One of the houses has a heart shape in its front gate.

A Sardinian warbler singing.

A dark phase Eleonora´s falcon flying past.

We take the bus to Agios Antonios harbour hamlet. Inhabited in the summer season. Now still deserted.

Waves, 20 April 2019

It is windy, causing waves to break on the rocky coast.

Pier, 20 April 2019

On the pier, this old boat and this crooked lamppost.

Agios Antonios, 20 April 2019

The deserted Agios Antonios hamlet is quiet, but the sea and the wind are not.

We walk along the mountain path from Agios Antonios back to Megalo Chorio.

Holy orchid, 20 April 2019

Along the path, beautiful flowers. They are holy orchids. Most not yet flowering. But the one on this photo is.

Common poppies. Barley.

Pyramidal orchids, 20 April 2019

Then, another orchid species. Pyramidal orchids.

A house martin flies past. Then, barn swallows.

Then, a much bigger bird. A long-legged buzzard.

This 15 June 2017 video is called Long-legged buzzard in flight (Buteo rufinus) Αετογερακίνα – Cyprus.

Flowers, 20 April 2019

More beautiful flowers yet before we reached Megalo Chorio.

Wildlife crime against orchids


This December 2018 Dutch video with English subtitles says about itself:

Wildlife crime fighter Sarina Veldman studies cake made from threatened orchids! Wait what? Yes, at Naturalis Science we study cake. Learn more in the first episode of our series regarding wildlife crime.

Ant pollinates orchid, video


This 14 March 2017 video says about itself:

Ant pollination of orchids is very rare. Until now only one case was known. In the Dolomites (Italy) we observed how the frog orchid (Dactylorhiza viridis) was pollinated by the ant Formica exsecta.

Orchids, why are they beautiful?

Orchid close-up. Habenaria radiata

29 September 2016

Pecteilis radiata (formerly known as Habenaria radiata) is a terrestrial orchid species, found in China, Japan and Korea. It grows in humid locations, often in full sun and can be cultivated as a bog plant.

I grew it in full south-western sun, next to my carnivorous plants. I watered it every day (or even twice a day on very hot days) with copious amounts of tap water or rain water whichever I had at the time, but I would NEVER let it sit in water (unlike my carnivorous plants) or let it dry out.

When it was in active growth, I fertilised it with a very dilute fertiliser (weaker than I use for Masdevallias) every fortnight.

When it started growing a flower spike, I stopped the fertilisation. The bloom only lasted for a week, and the second one never opened. The plant itself did not grow to its potential height, because it can grow up to 30 cm. I’ve got it potted up in a mix that looks like peat and perlite and I didn’t repot it. Now the plant is still outside and is preparing for the winter, so I water it less.

Thank you for reading this long description, and please remember that I am by no means an expert and I don’t think that I am very successful at growing this plant yet, so please use this information carefully.

Mechanism behind orchid beauty revealed

August 20, 2018

Researchers at Tohoku University in Japan have identified the gene related to the greenish flower mutation in the Habenaria [radiata] orchid.

Associate Professor Akira Kanno and PhD candidate Mai Mitoma have discovered that the greenish flower mutation is caused by a retrotransposon insertion in one of the floral homeotic genes in the Habenaria orchid. The modification of this gene by a genetic transformation system enables the development of greenish flowers in orchids and other plant species.

Orchids are important ornamental plants with high commercial value. The orchid lip, which acts as a landing platform for pollinators (insects) can vary in shape, form and color. At the center of the flower, an orchid has a unique reproductive organ called a column. Botanists have been interested in the shape of the orchid flower for a long time, however, until now the molecular mechanism of the orchid flower development has been largely unclear. Being able to modify orchid floral structures through genetic engineering would be very valuable for orchid breeders allowing for an increase in orchid production.

Kanno explained the process, which was undertaken to reveal the mechanism: “first, we used a mutant orchid cultivar with greenish flowers to analyze the important genes related to flower development in orchids. Then we found the retrotransposon insertion in one of the floral homeotic genes called the SEPALLATA-like gene in the mutant orchid cultivar.”

This mutant cultivar has greenish flowers. The loss-of-function of the SEPALLATA-like gene transformed the white petals to greenish organs and the column was converted into greenish leaf-like organs; revealing that the SEPALLATA-like gene is essential for petal, lip and column development in orchids.

In the future, the team aims to modify the SEPALLATA-like gene in other orchid species. It is thought that the reduced expression of the SEPALLATA-like gene may produce greenish flowers. These transgenic plants may help us to better understand the molecular mechanism of floral development in orchids.

Orchid in Florida, USA, video


This video from the USA says about itself:

29 March 2018

A rare native Florida Orchid, I believe the Crested Coralroot (Hexalectris spicata) suddenly appeared in the Backyard in a protected semi-shaded drier area. It is unusual to spot native orchids in Florida out in the bush because of the density of other plants and brush. This one somehow managed to grow from wind-borne seeds as an isolated plant under a growing palmetto tree among lava rock ground cover – Go Figure. You will notice it has aphids at the new growth at the tip of the main flower. I love it when I spot an unusual bit of Nature that might otherwise be overlooked.
