Floral morphologies of wind orchid mutants and schematic diagrams of flowers (insets). A and B, A frontal (A) and side (B) view of the wild-type wind orchid flower. C and D, Mutants with a homeotic conversion of floral organs from a labellum to an inner tepal (C) and vice versa (D) with near-radial floral symmetry. E–G, Mutants with decreased (E and F) or increased (G) floral organ number. H and I, Mutants with degenerative tepal development. J to N, Flower determinacy mutants. These mutant flowers maintain meristematic activity and continue to produce tepals (J), leaf-like tepals (K), tepals and labella (L), or labella (M and N). i, Inner tepal (colored purple in the diagrams); o, outer tepal (gray in the diagrams); la, labellum (white in the diagrams); g, gynostemium; s, spur; pe, pedicel; d-o, dorsal outer tepal; v-o, ventral outer tepal. Bars = 3.00 mm.
