This is one of the smallest Orchids in the World, as far as I know – It’s so small, you need to use manual focus most of the time – Not a favourite with Orchid-lovers, but for those who love the unusual, this is really something. These were quite abundant in the Aldinga Scrub – Here’s a Link to John Walmsley’s page:

Caladenia latifolia aka Pink Fairies, Pink Fairy Orchid
Kingdom: Plantae
Phylum: Angiosperms
Class: Monocots (or Liliopsida…?!)
Order: Asparagales
Family: Orchidaceae
Subfamily: Orchidoideae
Aldinga Scrub – August 16th, 2014 – overcast conditions

Another Orchid that can be overlooked in passing because of its resemblance to the more common Glossodia major, or Purple Cockatoo, aka Waxlip, Orchid – It was a very exhilarating find for my brother and I – It was very close to the Cladia ferdinandii (Coral Lichen) enclosure – For more information on this species, look here: http://www.oznativeplants.com/plantdetail/Pink-Fairy-Orchid/Caladenia/latifolia/zz.html

The Onion Orchid And The Ant

Microtis arenaria aka Notched Onion Orchid (?)
Kingdom: Plantae
Class: Angiosperms
Subclass: Monocots
Order: Asparagales
Family: Orchidaceae
Subfamily: Orchidoideae
Tribe: Diurideae
Aldinga Scrub – November, 2013 – overcast conditions

When I first saw this species from a distance, I suspected it was a Microtis, because I had read about them – The others passed it by because they thought it was a weed – As inconsequential as they may appear, they are very unusual orchids – Here is an interesting quote from Wikipedia:
“Every flower tends to set seed, after being pollinated by wingless worker ants from the genus Iridomyrmex, attracted by nectar at the base of the lip. This is an exceptional case of pollination by ants, since ants tend to secrete an anti-fungal substance that kills pollen. This doesn’t seem to affect Microtis pollen.”
