POLLEN FACTS

FACT:

The pollen grains, in most orchids, are aggregated into packets containing thousands of pollen grains and usually are removed as a unit. (see photo top right)

Some self-pollinating orchid's pollinia lack coherence and readily break into fragments.  (see photo bottom right)

All species of Arachnorchis have a pair of yellow waxy glands at the base of the column.  (see photo bottom left)

SPECULATION:

There is speculation that these represent anthers to attract pollen seeking insects while an alternative thought is that they are remnants of a pollination strategy gone wrong.
