I think I've got the ID right. Our guide called this 'Angel-wing Begonia', but that seems to refer more commonly to an unrelated hybrid houseplant. Small plant (<50 cm tall, most of which is flower stalk), abundant trailside in cloud forest. Growth habit shot: http://www.flickr.com/photos/anitagould/5487377267/. I'll add to iNat when the tag starts working.
