Collection of interesting natural things

I took the picture above to see if I could get a good shot of the ocelli - three secondary eyes between the big ones. They are just about visible. Why spanning tree? It's a routing term, from each user's perspective the network looks like a spanning tree - with no loops and only one route to any place. Every user's spanning tree is unique.

Orchids

Interesting day today with the Box Hill Volunteers, we spotted some interesting orchids... the rare butterfly orchid
and as a bonus extra, a birds nest orchid... this is in full flower and you can see the pollen on the flowers - but it seems devoid of chlorophyll, and apparently derives its energy from a symbiotic relationship with some fungi


I saw this, as yet, unnamed orchid - perhaps a man orchid, but I'm not sure...

and finally... a white Helleborine (Cephalanthera damasonium)
