Author's notes

Found with Jean and Eyal. Approximately 20 plants flowering. Growing in leaf litter in more 'exposed', open areas. Tended to grow where Bracken ferns were few and far between. I think this made it just within CNM's project boundaries! DL Jones has IDed this as D. atrans.

Hmm I don't think this is P alveata. But I am not sure what it is! Looks almost like a mix between P atrans and P decurva. Any chance you have more photos of other flowers in the population? Were they all still flowering?

I will check through my images, but I might to flick you an email because they won't all fit within the 5 image limit for each sighting. I have another couple of colonies of what is presumably the same species.

I have uploaded more photos. If I remember correctly, there are 4 individual plants in these photos. Images 3 and 4 are of the same individual, but image 2 might be that same plant too.
Jean believed it to be D. alveata due to the blunt, black labellum and flat sinus. However she was pointing out features that made it distinct from D. obtusa. I will admit that she was also pretty keen to get photos of this species, so there may be an element of wishful thinking (although we hope not).

Thanks for adding those photos. Feel free to send me more if you have different angles. The 3 and 4 angle does look more along the lines of Pt alveata but I'm still not convinced. There is a taxon which Gary Backhouse calls 'foothill forest' or aff. alveata which perhaps is more likely than true alveata for this one. It's definitely different to Pt decurva but not sure if we can rule out Pt atrans? The brown tip to the hood and the short and somewhat clubbed lateral sepals would point more towards Pt atrans than Pt alveata.

David Jones also identified as P atrans.
