Excellent images of Griffinia Steve.
Below a few images of bulbs from our recent trips to Peru:
First, two dryland plants from 3000m, Arequipa Province, southern Peru - a small irid with a single leaf, Mastigostyla hoppii, and Oziroe acaulis (Asparagaceae).
The final two irids are from the same elevation further north around Cusco - Hesperoxiphium herrerae and Hesperoxiphiumn peruvianum.
