There is a lot of confusion with plant taxonomy at the moment, and this is one of the victims – Some call it Caladenia leptochila, and others use the name Arachnorchis leptochila ssp leptochila. It often grows nearby to other species such as Caladenia tentaculata, but it is much more slender and the scented tentacled petals, or segments,  curve more vertically upwards. It has a hairy stem and is 15-45cm high.
Its flowers can be seen usually on solitary spikes in Spring, from September to November in the Mount Lofty Ranges. According to NOSSA, it prefers “leached, stony soils”. I first encountered it in close proximity to Caladenia tentaculata and at first thought it must be an emerging flower of that species, but after walking around the gravelly, gentle slope, I saw there were clearly two species – I was so stunned by these two species and the others I saw that day! One of the greatest days of my life and my brother and I still refer to that day as Orchid Day! See my other posts on Spider-orchid species here:

I haven’t seen an Arthropodium with this colour or quite this shape before – I really don’t know why this looks like this. I have noticed the way the flowers connect to the stems is a little different, thinner and more feeble than Arthropodium strictum, and also the arrangement along the stem, and possibly small differences in the sex parts, plus the edges of the petals almost look serrated, whereas A. strictum looks more fluted and undulating – The colours on the stamens are different in my specimens, but many specimens are more purple on the anther part of the stamens and the greenish filament part which connects to the flower is cream yellow on mine – This is not, therefore, a universal example of the appearance of this flower and I have insufficient knowledge to know why these I have photographed differ. See also my entry on Arthropodium strictum aka Dichopogon strictus.

Montacute Conservation Park – November 15th, 2014 – mild to warm, overcast conditions

This common species has a sweet, vanilla-chocolatey scent – Very pleasing – Before European settlement, this species was widespread and abundant in open areas. See also my entry on Arthropodium fimbriatum aka Dichopogon fimbriatus.
