Evolution and development of fruits of Erycina pusilla and other orchid species
Fig 2
Ancestral state reconstruction of fruit ripening period (A), fruit orientation (B), fruit dehiscence type (C), number of slits in mature fruit (D), fusion of valves (E), and lignification of dehiscence zone (F) characters from stochastic mapping analysis based on joint sampling of nrITS, matK and rbcL (10,000 mapped trees). Posterior probabilities (pie charts) are mapped in a random stochastic character map. Note: * nodes have bootstrap values < 70%. Illustrations of fruits: (A-B) Character 1: Erycina pusilla (ripe in ≤4 months), Phalaenopsis equestris (ripe in >4 months); character 2: Habenaria eustachys (erect), Papilionanthe teres (pendant). (C-D) Character 3: Vanilla pompona (indehiscent), Arundina graminifolia (dehiscent); character 4: Lockhartia acuta (<3 slits), Guarianthe skinneri (≥3 slits). (E-F) Character 5: A. graminifolia (valves fused at the base and apex), Ornithocephalus valerioi (valves fused at the base only); character 6: E. pusilla (non-lignified dehiscence zones), Cynorkis fastigiata (lignified dehiscence zones).
