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.

@AMR if you scroll down to the bottom of the page there is a section called "Sighting Information" which has the record date as opposed to the upload date. It says this was recorded 18 September 2013.

This appears to show 18 May as the date of the record, perhaps it is the date it was uploaded or when the species was identified? A leaf usually emerges late winter with flowering mostly in Sept/Oct. ALA records (64 only) show all their records outside Sept/Oct are seed collections made in summer. Can a note be added to avoid misleading visitors?

Flowering too late for hispidula. Also note the differences in floral structure
