It shouldn't be vastly different than pollinating any orchid, right? Pull the pollinia out of the anther cap and place them on the stigmatic surface. The anther cap is usually on the tip of the column, and sometimes has a little 'tag' that you can pull with tweezers. Sometimes, pollinia pop out, so be careful. The stigmatic surface is usually on the underside of the column, behind the anther cap/stamenoid.
