Peter - I can't see a timeline; I think your record is the first record for this site. Perhaps someone can confirm? I have difficulties bringing up the distribution.

Peter - in that first photo the flower colour is not typical. The labellum is very light yellow.

Derek - I remember noting that at the time while that nearby appeared normal. I wondered if it was to do with the conditions as it was also a bit stunted.

Peter, I declare you the truffle pig for Canberra Spider Orchid! Reg the yellowish colour, could it be a colour mutant?

Waltraud - I will leave that to the experts ! However, it will be interesting to follow up next year to see if the same colouring emerges

The yellow colour might just be some natural variation. It might also be a function of the flower ageing, a response to nutrient deficiencies or a response to receiving too much/too little water.

I would exclude
1. ageing - given that nearby specimen which appears of older age has the typical colour;
2. nutrient deficiency - given that the surrounding vegetation appears well-nourished and (1);
3. too little water - given the amount of rain we had and (1).
It might be too much water but this would have an effect on close by specimen too?
colour variation of wildflowers based on mutation is not uncommon - it requires only a change of one locus in the DNA. In fact, these mutations are used by the horticulture industry to create variants.
