These are gorgeous large orchids. They are listed as critically endangered, and estimates are that the total population is 276 plants (2008). They are flowering beautifully at the moment.
This shot was obtained by focus stacking 42 individual shots, changing the focus slightly between each shot (this was done automatically). As it was windy, the flower kept moving substantially, and I had to align the images by hand. The easiest way was to open all the images as layers and create a new layer and place some red dots on it at places that were easily identified. You need multiple spots as as the focus changes some features become unrecognisable. Then you just align the individual layers to the spots. Once aligned I used Photoshop to do the blending (automatically!).
I came across these flowers on my recent trip – it is obvious where they got their name from. However I saw them described in one Visitors Centre as “Reef Flowers” – I suspect the staff had misheard. These seem to be relatively rare and often found next to new roadworks where the seeds have been spread with the gravel. In this case the flowers were next to a road built for a mining project between Wubin and Paynes Find.
The yellow flowers in the second image have nothing to do with the Wreath Flowers – they were just sharing the same piece of gravel.
