Aaron Clausen's very first sighting of this endangered spider orchid, which inspired the creation of CNM & NatureMapr

This record comes up as a Hackett record however it is clearly within Mt Majura nature reserve.

Yeah, the official record. One of the actual orchids I almost crushed with mountain bike tyre.

What an amazing journey! I remember the first meet on the mountain with a rogue bike rider ... so I thought...

You were pivotal in putting me in touch with the government @waltraud as the first person that responded to my messages:

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?

@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.

Thanks Matt. You must have a more privileged view of the website than I have. The sighting date isn't visible to me for any records of this species, though I can see it for others, presumably an artefact of limiting data for endangered species. I'm trying to construct a table of first and last flowering records for each year for a report where I am recommending the survey window for a population. Aren't we glad that someone is mining the information so meticulously?

@AMR I wasn't aware that those details were suppressed for most users. As a moderator this information is made visible to me.

Reported Date Time is deliberately suppressed to prevent the possible triangulation of sensitive records.
