Robert --
One possible cause of underexposure with the Incident method is failure to set the meter on 100 ISO—regardless of the actual speed of the film. For a common example, if you're using 400-speed film, and setting the meter on 400 ISO you'll underexpose by two stops.
The other question is your closeup calculation. If you're using a 320mm (12.6 inch) lens and measuring a total bellows length of 12-14 inches you're not very close to the subject. If what you measured is in addition to the focal length (total lens-too-film distance about 25 inches, then the bellows factor is about 2 stops and you're shooting the orchid at about life size.
