3D Images Via Stereo Pairs

Stereo pairs of Buttercup (Ranunculus repens and Ranunculus acris) shoot apices at various stages of ontogeny. Taken from Meicenheimer, R.D., 1979. Relationships between Shoot Growth and Changing Phyllotaxy of Ranunculus. American Journal of Botany. 66: 557-569. Three dimensional visualization of these images can be achieved by following these instructions :
  1. R. repens vegetative apex at 6.11 Plastochron Index (PI)
  2. R. repens vegetative apex at 6.58 PI
  3. R. acris vegetative apex at 9.17 PI
  4. R. repens transitional apex at 10.72 PI
  5. R. repens transitonal apex at 11.43
  6. R. repens sepal stage apex at 11.72 PI
  7. R. repens petal stage apex
  8. R. acris early stamen stage apex
  9. R. repens stamen stage apex with intact sepals
  10. R. repens stamen stage apex with sepals dissected off
  11. R. repens carpel initiation
  12. R. acris carpel initiation
  13. R. repens carpel initiation completed
  14. R. repens nearly mature floral apex
