Orchids


There are about 30,000 species of orchid worldwide making Orchidaceae the largest family of flowering plants. They are found in a diverse range of habitats.

Orchids have distinctive flowers, consisting of three sepals and three petals. The third petal is greatly modified into a specialised structure known as a labellum. Another distinctive feature is the column, a fusion of the sexual parts of the flower (stamens and style) into a fleshy structure. Most terrestrial orchids grow from a tuber which is replaced each year.

Some orchids are designated as rare and endangered plants. Others, although reasonably common, are very localised in their occurence. All orchids are protected species and should not be disturbed in their native habitat. For these reasons all orchids have been included as rare or sensitive plants.

I was surprised to find one growing in a neighbour’s front lawn.

Thanks for that.
There has been a bit of chatter in the last few days about the Corunastylis at that site.
Fast coming to the conclusion that it is C oligantha.
Photographed in 2022 and 2023 also.

@Tapirlord I believe this may be at the same location I visited today. If so, Tobias and Gavin Phillips (whom Lachlan recommended as an expert in this species group) think these plants are C oligantha, or possibly C sagittifera. The labellums have too much red to be C cornuta. Something to consider for the ID on this sighting?

I believe this is P. tadgellianum but the photos make a confident identification challenging. The leaf tip is only just showing signs of withering where P. sphacelatum would be much more withered at flowering.

I agree, we saw some flowering in the general area on the 8th of January. The altitude looks a little odd on the sighting, it is more like 940m (I think).
