Dischidia ovata at lower left, showing some nice light-stressed color (presumably, given the more shaded leaf areas are green). I think the ruby blush makes for a nice accent and hope it keeps it when I try it in another setup.
For anyone curious, some of the other denizens are: Peperomia 'Isabella Yellow' (lower center, looking slightly like a golden creeping Jenny in the pic but less so in real life), Codonanthe devosiana 'Paula' (roaming around, medium to yellow-green...incidentally over-lit as it should be, and used to be, a much darker green), Begonia vankerckhovenii (clump next to Dischidia with fine red edges to leaves), and some very, very bleached-out Peperomia prostrata wandering around. Upper right bromeliad is Neoregelia 'Domino' and lower right is Neoregelia ['Red Bird' x pauciflora], I think. Terete-leaved orchid clump at the base of the dark Neo is Leptotes bohnkiana.
