2 species: I expect one is the common onion orchid. I've found other [probable] onion orchids in this general location as well. In amongst them, another orchid - possibly a sun orchid? - only found 3 of these but I didn't hunt around too far. I'll monitor and will take photos if they flower later on.
Note there's also lots of onion grass - Romulea - in this area, mostly around the amenity track.
