Harvested some pollen a few moments ago from a ripe H. folliculata flower.
(tuning fork method)
(Image post harvest)
Notice the anthers have dropped down and become parallel with the pistil.
They have also turned from green to a nice bright yellow.
Tuning fork frequency = 512 Hz.
Pollen collected on a cdrom case:
(anything black plastic, easier to see the pollen IMHO)
Please excuse pic quality, quickie images with point and click camera
Thanks for looking,
