Here's a link to an image of Barbosella dusenii: http://www.pleurothallids.com/index....=369&Itemid=58
The low elevation indicates that this may be a warm growing species afterall. Neat cos there aren't a lot of warm growing Pleurothallids out there.
Amp: Barbosella IS in the Pleurothallid Alliance silly! :Pthat orchid seems to have spikes rising from the base of the leaf so im guessing it isn't part of the Pleurothallid alliance.
