Porroglossum portillae flowers almost continously. This small one from Ecuador usually develops 4 (non-resupinate) flowers on a flower stalk. Not at the same time but one after the other. So before everything has finished flowering, we are a few months further. Grows at 1300m to 1500m. Temperate and a lot of light. It has most of the time non-resupinate flowers, but not always, as can seen in the last picture.
